Working Capital Finance in New Zealand: Options, Costs and When to Use It

Indicative costs and what drives them

Pricing varies widely by lender, by how much security you offer and by your trading history, so treat any figure as a ballpark to be confirmed, not a quote. As a rough guide for the current market, bank business overdrafts tend to land in the low-to-high teens once the base rate and margin are combined, secured revolving credit is usually cheaper at single digits to the low teens, invoice finance is priced as a percentage of invoice value per period rather than a headline annual rate, and unsecured short-term loans sit well above bank rates. These ranges move with the Reserve Bank’s Official Cash Rate (OCR) and wider lending conditions, so it is worth understanding the broader picture in our guide to NZ interest rates.

Just as important as the interest rate are the fees and the structure around it. Watch for establishment or application fees, annual or line fees charged on your total limit (not just what you draw), management or service fees on invoice finance, early-repayment costs, and how interest is calculated — daily on the drawn balance is normal and fair for a revolving facility. Because a short-term loan is repaid over a short period, a seemingly small weekly fee can translate into a very large annualised cost, so always compare the total cost of borrowing in dollars, not just the advertised rate. Our guide to understanding loans walks through how rates, terms and fees combine into the true cost.

When a business needs working capital finance

The need almost always comes down to a timing mismatch between outgoings and income. Common triggers include:

• Seasonal cash-flow gaps — retailers stocking up before Christmas, or farmers covering costs between one harvest or payout and the next.
• Rapid growth that outpaces invoice collection, where winning more work means paying for more labour and materials before the money lands.
• Slow-paying customers, particularly large corporates and government agencies that pay to their own schedule rather than yours.
• Unexpected costs such as an equipment breakdown, an insurance excess, a compliance bill or a tax payment falling at an awkward time.
• A large new contract that requires significant upfront stock, materials or staffing before the first payment is received.

In each case the business is fundamentally sound — the problem is purely one of timing. That is exactly where short-term finance earns its keep. Where it does not help is in propping up a business whose costs structurally exceed its income; borrowing there only delays and deepens the issue, and the underlying numbers need to be fixed first.

How to choose the right option

The right product depends on the nature of your cash-flow gap rather than simply the cheapest headline rate. A revolving, unpredictable need — a buffer that rises and falls month to month — usually suits an overdraft or revolving credit facility, because you pay interest only on what you use and the facility stays in place for whenever you need it. A gap caused specifically by slow-paying customers points to invoice finance, which releases money you have genuinely already earned and grows with your sales. A one-off, urgent, short-lived need might justify a short-term loan, accepting a higher cost in exchange for speed. And a need tied to card-based sales might fit a merchant cash advance.

Whichever direction you lean, run the same checks: compare the total cost across at least two or three lenders; read the fine print on fees, limit reviews and early-repayment terms; and make sure the repayment pattern genuinely matches your cash-flow cycle, so repayments fall due around when money actually comes in rather than before it. Since GST timing is one of the most common cash-flow pressures for NZ businesses, it is worth setting money aside ahead of each return — our GST guide and calculator can help you plan for it.

Secured vs unsecured, and checking the lender

Working capital finance can be secured (backed by an asset such as property, the business’s debtors or a general security agreement) or unsecured (based on your trading record and cash flow alone). Secured facilities almost always carry lower rates and larger limits because the lender’s risk is reduced, but they put an asset at stake. Unsecured facilities are faster and keep your assets free, but cost more and tend to be smaller. Many business owners are also asked for a personal guarantee, which makes them personally liable if the business cannot repay — a significant commitment worth understanding fully before signing.

Before committing to any provider, confirm it is a registered financial service provider on New Zealand’s Financial Service Providers Register and that it belongs to an approved dispute-resolution scheme. Bank facilities come with that assurance automatically; with non-bank and fintech lenders it is worth checking, because the market includes everything from well-established specialists to high-cost short-term operators. A registered, reputable lender should set out all fees, the total cost and the repayment schedule clearly and in writing.

Common mistakes and improving the underlying cash flow

Finance is a tool, not a cure. The businesses that use it best also work on the cash flow that created the need in the first place, so they borrow by choice rather than necessity. The most common mistakes are borrowing to cover a structural loss rather than a timing gap; focusing on the weekly repayment instead of the total cost; taking a facility that is larger than needed and paying fees on the unused portion; and relying on expensive short-term finance as a permanent fixture. Alongside any facility, the practical levers that reduce the need to borrow include:

• Invoice promptly and accurately — the clock on getting paid only starts once the invoice is out.
• Tighten payment terms and make it easy to pay, with clear due dates and simple payment methods.
• Chase overdue debtors consistently rather than letting them drift.
• Negotiate supplier terms so what you owe and what you are owed are better aligned.
• Forecast and plan for seasonal dips and known lumpy costs such as tax, instead of being surprised by them.
• Keep a cash reserve where possible, so small shocks do not automatically mean borrowing.

Free, independent help is available through business.govt.nz and the Regional Business Partner Network, and an accountant or business adviser can help you model your cash flow and decide whether finance is the right answer at all.

The bottom line

Working capital finance is about timing rather than survival: it bridges the gap between money going out and money coming in, so a profitable business is not tripped up by its own billing cycle. Bank overdrafts and revolving credit facilities are the cheapest options for ongoing, flexible needs; invoice finance suits businesses held up by large, slow-paying invoices; and short-term loans offer speed for urgent one-offs at a higher price. Match the product to the specific problem, compare the true cost rather than the headline rate, and keep working on the underlying cash flow so you borrow because it is the smart choice, not because you have run out of room.

Frequently asked questions (FAQ)

What is working capital finance?

It is short-term funding that helps a business cover day-to-day running costs — payroll, suppliers, stock and tax — when cash flow is tight, particularly in the gap between invoicing a customer and being paid. The main options in New Zealand are business overdrafts, revolving credit facilities, invoice finance and short-term business loans.

What is the difference between an overdraft and a revolving credit facility?

Both let you draw down and repay flexibly, paying interest only on what you use. An overdraft is usually smaller and attached to your business bank account, making it ideal for everyday smoothing. A revolving credit facility tends to be larger, more structured and often secured against property or assets, which makes it cheaper per dollar and better suited to bigger SMEs with substantial, reusable funding needs.

How does invoice finance work?

Invoice finance lets you borrow against unpaid invoices. A lender advances a large portion of an invoice’s value straight away — typically around 70% to 90% — then releases the balance, minus its fees, once your customer pays. It suits businesses that issue sizeable invoices to creditworthy customers on 30 to 90 day terms and are held up by slow payment.

How much does working capital finance cost?

It depends on the product, your security and your trading history. As a broad guide, bank overdrafts tend to sit in the low-to-high teens once the base rate and margin combine, secured revolving credit is cheaper, invoice finance is charged as a percentage of invoice value per period, and unsecured short-term loans cost considerably more. These are indicative figures only — confirm current rates and fees with the lender and always compare the total cost of borrowing in dollars.

Should I use finance or just fix my cash flow?

Ideally both. Finance is a useful tool for genuine, temporary timing gaps, but it costs money, so alongside it you should improve the underlying cash flow — invoicing promptly, tightening payment terms, chasing debtors and planning for seasonal dips. That reduces how often you need to borrow. Free help is available through business.govt.nz and the Regional Business Partner Network.

The main types of working capital finance

New Zealand businesses have several working capital products to choose from, and each is built for a different kind of cash-flow gap. The four most common are the business overdraft, the revolving credit facility, invoice finance and the short-term business loan, with a handful of other options such as merchant cash advances, trade finance and business credit cards filling niches around the edges.

Business overdraft

An overdraft is a limit attached to your business transaction account that lets the balance go below zero up to an agreed amount. It is the classic buffer for small, everyday fluctuations — the week payroll lands before a big customer pays. You draw on it automatically just by spending, and you pay interest only on the amount you are actually overdrawn, calculated daily. All the major banks (ANZ, ASB, BNZ, Kiwibank and Westpac) offer business overdrafts, usually priced as a base ‘working capital’ rate plus a margin that depends on your limit and security, with an annual or management fee on top. Overdrafts are flexible and quick to use once arranged, but limits are typically modest and the bank can usually review or reduce the facility, so they suit ongoing, low-level smoothing rather than large or permanent funding needs.

Revolving credit facility

A revolving credit facility works on the same draw-down-and-repay principle as an overdraft but is generally larger, more structured and more often secured — frequently against property or business assets. You have an approved limit, you can draw and repay as often as you like, and again you pay interest only on the balance outstanding. Because it is secured, the interest rate is usually lower than an unsecured overdraft, which makes it a cost-effective option for bigger small-to-medium enterprises (SMEs) that need a sizeable, reusable line of credit. The trade-off is that it is more involved to set up and puts an asset on the line if things go wrong.

Invoice finance (debtor finance)

Invoice finance — also called debtor finance, invoice discounting or factoring — lets you borrow against money your customers already owe you. Instead of waiting 30 to 90 days for an invoice to be paid, a lender advances you a large slice of its value straight away, typically around 70% to 90%, and releases the remaining balance (minus its fees) once your customer settles. It directly targets the most common cash-flow problem of all: good sales tied up in slow-paying invoices. Specialist providers such as ScotPac, Heartland and Bibby Financial Services operate in this space in New Zealand, and the facility usually scales with your sales, so the more you invoice the more funding you can unlock. The two broad flavours are factoring, where the lender manages collection and your customers know about the arrangement, and invoice discounting, where it stays confidential and you keep chasing payment yourself. Invoice finance suits businesses that issue sizeable invoices to creditworthy customers on standard trade terms; it is less useful if you sell mostly on the spot or for cash.

Short-term business loan

A short-term business loan is a lump sum repaid over a defined, usually brief period — anywhere from a few weeks to a couple of years — often through daily or weekly instalments. Non-bank fintech lenders have made these fast and easy to access, sometimes with approval in a day based on your bank-account or accounting-software data rather than lengthy paperwork. That speed is the appeal: it suits a one-off, urgent, short-lived need such as bridging a gap before a confirmed payment arrives. The catch is cost. Unsecured short-term loans carry much higher rates than bank facilities, and because the term is short the effective annual cost can be steep once fees are included. They are best treated as a tool for genuine one-offs, not a standing source of cheap money.

Other options

Beyond the big four, a few other products can cover specific situations:

• Merchant cash advance: an advance repaid as a fixed percentage of your daily card or EFTPOS takings. Repayments flex with sales, which suits seasonal retail and hospitality, but the cost per dollar borrowed is typically high.
• Trade and supply-chain finance: funding to pay suppliers — often overseas — before your own stock sells. Useful for importers and businesses with long lead times between ordering and selling.
• Business credit cards: handy for small, short-term purchases with an interest-free window if cleared in full each month, but an expensive way to carry a balance for long.
• Government support and advice: not finance itself, but the Regional Business Partner Network and business.govt.nz offer free or subsidised guidance that can reduce how much you need to borrow in the first place.

For the wider lending picture, our business finance guide maps the full range of options, and our small business loans guide covers term lending for SMEs in more depth. If your cash needs relate to buying equipment or vehicles rather than smoothing cash flow, that is a different category covered in our asset finance guide.

Indicative costs and what drives them

Pricing varies widely by lender, by how much security you offer and by your trading history, so treat any figure as a ballpark to be confirmed, not a quote. As a rough guide for the current market, bank business overdrafts tend to land in the low-to-high teens once the base rate and margin are combined, secured revolving credit is usually cheaper at single digits to the low teens, invoice finance is priced as a percentage of invoice value per period rather than a headline annual rate, and unsecured short-term loans sit well above bank rates.

Working capital finance helps New Zealand businesses manage the money they need to run day to day — covering wages, suppliers, rent, stock and tax while they wait to be paid by their own customers. For many Kiwi firms, reliable access to short-term cash is every bit as important as long-term investment or growth funding, because even a profitable business can be caught out when money goes out the door faster than it comes in. This guide explains what working capital is, the main finance options available in New Zealand, roughly what each costs, how to choose between them and when a business actually needs them. It is general information about the market, not financial advice or a recommendation of any lender or product.

What working capital finance is

Working capital is the money a business has available to meet its short-term obligations. In accounting terms it is your current assets (cash, stock and money owed to you by customers) minus your current liabilities (money you owe to suppliers, staff, the bank and Inland Revenue in the near term). When that number is healthy, you can pay your bills comfortably as they fall due. When it is tight, you feel the squeeze — even if the business is winning plenty of work and turning a profit on paper.

The reason the squeeze happens is the cash-flow cycle: the gap between spending money to deliver a product or service and actually collecting the cash for it. A builder buys materials and pays a crew this week, but the client might not settle the invoice for 30, 60 or even 90 days. A retailer pays for stock before the season starts and only recovers it as goods sell. That timing gap is where working capital finance comes in — it bridges the space between money going out and money coming in, so the day-to-day running of the business is not held hostage by its billing calendar.

Importantly, working capital finance is about timing, not rescue. It is designed to smooth a genuine, temporary gap in a viable business. It is not a sensible long-term fix for a business that consistently spends more than it earns — in that situation, borrowing simply adds interest to a deeper problem that needs solving at its root.

The bottom line

Working capital finance is about timing rather than survival: it bridges the gap between money going out and money coming in, so a profitable business is not tripped up by its own billing cycle. Bank overdrafts and revolving credit facilities are the cheapest options for ongoing, flexible needs; invoice finance suits businesses held up by large, slow-paying invoices; and short-term loans offer speed for urgent one-offs at a higher price. Match the product to the specific problem, compare the true cost rather than the headline rate, and keep working on the underlying cash flow so you borrow because it is the smart choice, not because you have run out of room.

Frequently asked questions (FAQ)

What is working capital finance?

It is short-term funding that helps a business cover day-to-day running costs — payroll, suppliers, stock and tax — when cash flow is tight, particularly in the gap between invoicing a customer and being paid. The main options in New Zealand are business overdrafts, revolving credit facilities, invoice finance and short-term business loans.

What is the difference between an overdraft and a revolving credit facility?

Both let you draw down and repay flexibly, paying interest only on what you use. An overdraft is usually smaller and attached to your business bank account, making it ideal for everyday smoothing. A revolving credit facility tends to be larger, more structured and often secured against property or assets, which makes it cheaper per dollar and better suited to bigger SMEs with substantial, reusable funding needs.

How does invoice finance work?

Invoice finance lets you borrow against unpaid invoices. A lender advances a large portion of an invoice’s value straight away — typically around 70% to 90% — then releases the balance, minus its fees, once your customer pays. It suits businesses that issue sizeable invoices to creditworthy customers on 30 to 90 day terms and are held up by slow payment.

How much does working capital finance cost?

It depends on the product, your security and your trading history. As a broad guide, bank overdrafts tend to sit in the low-to-high teens once the base rate and margin combine, secured revolving credit is cheaper, invoice finance is charged as a percentage of invoice value per period, and unsecured short-term loans cost considerably more. These are indicative figures only — confirm current rates and fees with the lender and always compare the total cost of borrowing in dollars.

Should I use finance or just fix my cash flow?

Ideally both. Finance is a useful tool for genuine, temporary timing gaps, but it costs money, so alongside it you should improve the underlying cash flow — invoicing promptly, tightening payment terms, chasing debtors and planning for seasonal dips. That reduces how often you need to borrow. Free help is available through business.govt.nz and the Regional Business Partner Network.

The main types of working capital finance

New Zealand businesses have several working capital products to choose from, and each is built for a different kind of cash-flow gap. The four most common are the business overdraft, the revolving credit facility, invoice finance and the short-term business loan, with a handful of other options such as merchant cash advances, trade finance and business credit cards filling niches around the edges.

Business overdraft

An overdraft is a limit attached to your business transaction account that lets the balance go below zero up to an agreed amount. It is the classic buffer for small, everyday fluctuations — the week payroll lands before a big customer pays. You draw on it automatically just by spending, and you pay interest only on the amount you are actually overdrawn, calculated daily. All the major banks (ANZ, ASB, BNZ, Kiwibank and Westpac) offer business overdrafts, usually priced as a base ‘working capital’ rate plus a margin that depends on your limit and security, with an annual or management fee on top. Overdrafts are flexible and quick to use once arranged, but limits are typically modest and the bank can usually review or reduce the facility, so they suit ongoing, low-level smoothing rather than large or permanent funding needs.

Revolving credit facility

A revolving credit facility works on the same draw-down-and-repay principle as an overdraft but is generally larger, more structured and more often secured — frequently against property or business assets. You have an approved limit, you can draw and repay as often as you like, and again you pay interest only on the balance outstanding. Because it is secured, the interest rate is usually lower than an unsecured overdraft, which makes it a cost-effective option for bigger small-to-medium enterprises (SMEs) that need a sizeable, reusable line of credit. The trade-off is that it is more involved to set up and puts an asset on the line if things go wrong.

Invoice finance (debtor finance)

Invoice finance — also called debtor finance, invoice discounting or factoring — lets you borrow against money your customers already owe you. Instead of waiting 30 to 90 days for an invoice to be paid, a lender advances you a large slice of its value straight away, typically around 70% to 90%, and releases the remaining balance (minus its fees) once your customer settles. It directly targets the most common cash-flow problem of all: good sales tied up in slow-paying invoices. Specialist providers such as ScotPac, Heartland and Bibby Financial Services operate in this space in New Zealand, and the facility usually scales with your sales, so the more you invoice the more funding you can unlock. The two broad flavours are factoring, where the lender manages collection and your customers know about the arrangement, and invoice discounting, where it stays confidential and you keep chasing payment yourself. Invoice finance suits businesses that issue sizeable invoices to creditworthy customers on standard trade terms; it is less useful if you sell mostly on the spot or for cash.

Short-term business loan

A short-term business loan is a lump sum repaid over a defined, usually brief period — anywhere from a few weeks to a couple of years — often through daily or weekly instalments. Non-bank fintech lenders have made these fast and easy to access, sometimes with approval in a day based on your bank-account or accounting-software data rather than lengthy paperwork. That speed is the appeal: it suits a one-off, urgent, short-lived need such as bridging a gap before a confirmed payment arrives. The catch is cost. Unsecured short-term loans carry much higher rates than bank facilities, and because the term is short the effective annual cost can be steep once fees are included. They are best treated as a tool for genuine one-offs, not a standing source of cheap money.

Other options

Beyond the big four, a few other products can cover specific situations:

• Merchant cash advance: an advance repaid as a fixed percentage of your daily card or EFTPOS takings. Repayments flex with sales, which suits seasonal retail and hospitality, but the cost per dollar borrowed is typically high.
• Trade and supply-chain finance: funding to pay suppliers — often overseas — before your own stock sells. Useful for importers and businesses with long lead times between ordering and selling.
• Business credit cards: handy for small, short-term purchases with an interest-free window if cleared in full each month, but an expensive way to carry a balance for long.
• Government support and advice: not finance itself, but the Regional Business Partner Network and business.govt.nz offer free or subsidised guidance that can reduce how much you need to borrow in the first place.

For the wider lending picture, our business finance guide maps the full range of options, and our small business loans guide covers term lending for SMEs in more depth. If your cash needs relate to buying equipment or vehicles rather than smoothing cash flow, that is a different category covered in our asset finance guide.

Indicative costs and what drives them

Pricing varies widely by lender, by how much security you offer and by your trading history, so treat any figure as a ballpark to be confirmed, not a quote. As a rough guide for the current market, bank business overdrafts tend to land in the low-to-high teens once the base rate and margin are combined, secured revolving credit is usually cheaper at single digits to the low teens, invoice finance is priced as a percentage of invoice value per period rather than a headline annual rate, and unsecured short-term loans sit well above bank rates. These ranges move with the Reserve Bank’s Official Cash Rate (OCR) and wider lending conditions, so it is worth understanding the broader picture in our guide to NZ interest rates.

Just as important as the interest rate are the fees and the structure around it. Watch for establishment or application fees, annual or line fees charged on your total limit (not just what you draw), management or service fees on invoice finance, early-repayment costs, and how interest is calculated — daily on the drawn balance is normal and fair for a revolving facility. Because a short-term loan is repaid over a short period, a seemingly small weekly fee can translate into a very large annualised cost, so always compare the total cost of borrowing in dollars, not just the advertised rate. Our guide to understanding loans walks through how rates, terms and fees combine into the true cost.

When a business needs working capital finance

The need almost always comes down to a timing mismatch between outgoings and income. Common triggers include:

• Seasonal cash-flow gaps — retailers stocking up before Christmas, or farmers covering costs between one harvest or payout and the next.
• Rapid growth that outpaces invoice collection, where winning more work means paying for more labour and materials before the money lands.
• Slow-paying customers, particularly large corporates and government agencies that pay to their own schedule rather than yours.
• Unexpected costs such as an equipment breakdown, an insurance excess, a compliance bill or a tax payment falling at an awkward time.
• A large new contract that requires significant upfront stock, materials or staffing before the first payment is received.

In each case the business is fundamentally sound — the problem is purely one of timing. That is exactly where short-term finance earns its keep. Where it does not help is in propping up a business whose costs structurally exceed its income; borrowing there only delays and deepens the issue, and the underlying numbers need to be fixed first.

How to choose the right option

The right product depends on the nature of your cash-flow gap rather than simply the cheapest headline rate. A revolving, unpredictable need — a buffer that rises and falls month to month — usually suits an overdraft or revolving credit facility, because you pay interest only on what you use and the facility stays in place for whenever you need it. A gap caused specifically by slow-paying customers points to invoice finance, which releases money you have genuinely already earned and grows with your sales. A one-off, urgent, short-lived need might justify a short-term loan, accepting a higher cost in exchange for speed. And a need tied to card-based sales might fit a merchant cash advance.

Whichever direction you lean, run the same checks: compare the total cost across at least two or three lenders; read the fine print on fees, limit reviews and early-repayment terms; and make sure the repayment pattern genuinely matches your cash-flow cycle, so repayments fall due around when money actually comes in rather than before it. Since GST timing is one of the most common cash-flow pressures for NZ businesses, it is worth setting money aside ahead of each return — our GST guide and calculator can help you plan for it.

Secured vs unsecured, and checking the lender

Working capital finance can be secured (backed by an asset such as property, the business’s debtors or a general security agreement) or unsecured (based on your trading record and cash flow alone). Secured facilities almost always carry lower rates and larger limits because the lender’s risk is reduced, but they put an asset at stake. Unsecured facilities are faster and keep your assets free, but cost more and tend to be smaller. Many business owners are also asked for a personal guarantee, which makes them personally liable if the business cannot repay — a significant commitment worth understanding fully before signing.

Before committing to any provider, confirm it is a registered financial service provider on New Zealand’s Financial Service Providers Register and that it belongs to an approved dispute-resolution scheme. Bank facilities come with that assurance automatically; with non-bank and fintech lenders it is worth checking, because the market includes everything from well-established specialists to high-cost short-term operators. A registered, reputable lender should set out all fees, the total cost and the repayment schedule clearly and in writing.

Common mistakes and improving the underlying cash flow

Finance is a tool, not a cure. The businesses that use it best also work on the cash flow that created the need in the first place, so they borrow by choice rather than necessity. The most common mistakes are borrowing to cover a structural loss rather than a timing gap; focusing on the weekly repayment instead of the total cost; taking a facility that is larger than needed and paying fees on the unused portion; and relying on expensive short-term finance as a permanent fixture. Alongside any facility, the practical levers that reduce the need to borrow include:

• Invoice promptly and accurately — the clock on getting paid only starts once the invoice is out.
• Tighten payment terms and make it easy to pay, with clear due dates and simple payment methods.
• Chase overdue debtors consistently rather than letting them drift.
• Negotiate supplier terms so what you owe and what you are owed are better aligned.
• Forecast and plan for seasonal dips and known lumpy costs such as tax, instead of being surprised by them.
• Keep a cash reserve where possible, so small shocks do not automatically mean borrowing.

Working capital finance helps New Zealand businesses manage the money they need to run day to day — covering wages, suppliers, rent, stock and tax while they wait to be paid by their own customers. For many Kiwi firms, reliable access to short-term cash is every bit as important as long-term investment or growth funding, because even a profitable business can be caught out when money goes out the door faster than it comes in. This guide explains what working capital is, the main finance options available in New Zealand, roughly what each costs, how to choose between them and when a business actually needs them. It is general information about the market, not financial advice or a recommendation of any lender or product.

What working capital finance is

Working capital is the money a business has available to meet its short-term obligations. In accounting terms it is your current assets (cash, stock and money owed to you by customers) minus your current liabilities (money you owe to suppliers, staff, the bank and Inland Revenue in the near term). When that number is healthy, you can pay your bills comfortably as they fall due. When it is tight, you feel the squeeze — even if the business is winning plenty of work and turning a profit on paper.

The reason the squeeze happens is the cash-flow cycle: the gap between spending money to deliver a product or service and actually collecting the cash for it. A builder buys materials and pays a crew this week, but the client might not settle the invoice for 30, 60 or even 90 days. A retailer pays for stock before the season starts and only recovers it as goods sell. That timing gap is where working capital finance comes in — it bridges the space between money going out and money coming in, so the day-to-day running of the business is not held hostage by its billing calendar.

Importantly, working capital finance is about timing, not rescue. It is designed to smooth a genuine, temporary gap in a viable business. It is not a sensible long-term fix for a business that consistently spends more than it earns — in that situation, borrowing simply adds interest to a deeper problem that needs solving at its root.

New Zealand businesses have several working capital products to choose from, and each is built for a different kind of cash-flow gap. The four most common are the business overdraft, the revolving credit facility, invoice finance and the short-term business loan, with a handful of other options such as merchant cash advances, trade finance and business credit cards filling niches around the edges.

Business overdraft

An overdraft is a limit attached to your business transaction account that lets the balance go below zero up to an agreed amount. It is the classic buffer for small, everyday fluctuations — the week payroll lands before a big customer pays. You draw on it automatically just by spending, and you pay interest only on the amount you are actually overdrawn, calculated daily. All the major banks (ANZ, ASB, BNZ, Kiwibank and Westpac) offer business overdrafts, usually priced as a base ‘working capital’ rate plus a margin that depends on your limit and security, with an annual or management fee on top. Overdrafts are flexible and quick to use once arranged, but limits are typically modest and the bank can usually review or reduce the facility, so they suit ongoing, low-level smoothing rather than large or permanent funding needs.

Revolving credit facility

A revolving credit facility works on the same draw-down-and-repay principle as an overdraft but is generally larger, more structured and more often secured — frequently against property or business assets. You have an approved limit, you can draw and repay as often as you like, and again you pay interest only on the balance outstanding. Because it is secured, the interest rate is usually lower than an unsecured overdraft, which makes it a cost-effective option for bigger small-to-medium enterprises (SMEs) that need a sizeable, reusable line of credit. The trade-off is that it is more involved to set up and puts an asset on the line if things go wrong.

Invoice finance (debtor finance)

Invoice finance — also called debtor finance, invoice discounting or factoring — lets you borrow against money your customers already owe you. Instead of waiting 30 to 90 days for an invoice to be paid, a lender advances you a large slice of its value straight away, typically around 70% to 90%, and releases the remaining balance (minus its fees) once your customer settles. It directly targets the most common cash-flow problem of all: good sales tied up in slow-paying invoices. Specialist providers such as ScotPac, Heartland and Bibby Financial Services operate in this space in New Zealand, and the facility usually scales with your sales, so the more you invoice the more funding you can unlock. The two broad flavours are factoring, where the lender manages collection and your customers know about the arrangement, and invoice discounting, where it stays confidential and you keep chasing payment yourself. Invoice finance suits businesses that issue sizeable invoices to creditworthy customers on standard trade terms; it is less useful if you sell mostly on the spot or for cash.

Short-term business loan

A short-term business loan is a lump sum repaid over a defined, usually brief period — anywhere from a few weeks to a couple of years — often through daily or weekly instalments. Non-bank fintech lenders have made these fast and easy to access, sometimes with approval in a day based on your bank-account or accounting-software data rather than lengthy paperwork. That speed is the appeal: it suits a one-off, urgent, short-lived need such as bridging a gap before a confirmed payment arrives. The catch is cost. Unsecured short-term loans carry much higher rates than bank facilities, and because the term is short the effective annual cost can be steep once fees are included. They are best treated as a tool for genuine one-offs, not a standing source of cheap money.

Other options

Beyond the big four, a few other products can cover specific situations:

• Merchant cash advance: an advance repaid as a fixed percentage of your daily card or EFTPOS takings. Repayments flex with sales, which suits seasonal retail and hospitality, but the cost per dollar borrowed is typically high.
• Trade and supply-chain finance: funding to pay suppliers — often overseas — before your own stock sells. Useful for importers and businesses with long lead times between ordering and selling.
• Business credit cards: handy for small, short-term purchases with an interest-free window if cleared in full each month, but an expensive way to carry a balance for long.
• Government support and advice: not finance itself, but the Regional Business Partner Network and business.govt.nz offer free or subsidised guidance that can reduce how much you need to borrow in the first place.

For the wider lending picture, our business finance guide maps the full range of options, and our small business loans guide covers term lending for SMEs in more depth. If your cash needs relate to buying equipment or vehicles rather than smoothing cash flow, that is a different category covered in our asset finance guide.

Indicative costs and what drives them

Pricing varies widely by lender, by how much security you offer and by your trading history, so treat any figure as a ballpark to be confirmed, not a quote. As a rough guide for the current market, bank business overdrafts tend to land in the low-to-high teens once the base rate and margin are combined, secured revolving credit is usually cheaper at single digits to the low teens, invoice finance is priced as a percentage of invoice value per period rather than a headline annual rate, and unsecured short-term loans sit well above bank rates. These ranges move with the Reserve Bank’s Official Cash Rate (OCR) and wider lending conditions, so it is worth understanding the broader picture in our guide to NZ interest rates.

Just as important as the interest rate are the fees and the structure around it. Watch for establishment or application fees, annual or line fees charged on your total limit (not just what you draw), management or service fees on invoice finance, early-repayment costs, and how interest is calculated — daily on the drawn balance is normal and fair for a revolving facility. Because a short-term loan is repaid over a short period, a seemingly small weekly fee can translate into a very large annualised cost, so always compare the total cost of borrowing in dollars, not just the advertised rate. Our guide to understanding loans walks through how rates, terms and fees combine into the true cost.

When a business needs working capital finance

The need almost always comes down to a timing mismatch between outgoings and income. Common triggers include:

• Seasonal cash-flow gaps — retailers stocking up before Christmas, or farmers covering costs between one harvest or payout and the next.
• Rapid growth that outpaces invoice collection, where winning more work means paying for more labour and materials before the money lands.
• Slow-paying customers, particularly large corporates and government agencies that pay to their own schedule rather than yours.
• Unexpected costs such as an equipment breakdown, an insurance excess, a compliance bill or a tax payment falling at an awkward time.
• A large new contract that requires significant upfront stock, materials or staffing before the first payment is received.

In each case the business is fundamentally sound — the problem is purely one of timing. That is exactly where short-term finance earns its keep. Where it does not help is in propping up a business whose costs structurally exceed its income; borrowing there only delays and deepens the issue, and the underlying numbers need to be fixed first.

How to choose the right option

The right product depends on the nature of your cash-flow gap rather than simply the cheapest headline rate. A revolving, unpredictable need — a buffer that rises and falls month to month — usually suits an overdraft or revolving credit facility, because you pay interest only on what you use and the facility stays in place for whenever you need it. A gap caused specifically by slow-paying customers points to invoice finance, which releases money you have genuinely already earned and grows with your sales. A one-off, urgent, short-lived need might justify a short-term loan, accepting a higher cost in exchange for speed. And a need tied to card-based sales might fit a merchant cash advance.

Whichever direction you lean, run the same checks: compare the total cost across at least two or three lenders; read the fine print on fees, limit reviews and early-repayment terms; and make sure the repayment pattern genuinely matches your cash-flow cycle, so repayments fall due around when money actually comes in rather than before it. Since GST timing is one of the most common cash-flow pressures for NZ businesses, it is worth setting money aside ahead of each return — our GST guide and calculator can help you plan for it.

Secured vs unsecured, and checking the lender

Working capital finance can be secured (backed by an asset such as property, the business’s debtors or a general security agreement) or unsecured (based on your trading record and cash flow alone). Secured facilities almost always carry lower rates and larger limits because the lender’s risk is reduced, but they put an asset at stake. Unsecured facilities are faster and keep your assets free, but cost more and tend to be smaller. Many business owners are also asked for a personal guarantee, which makes them personally liable if the business cannot repay — a significant commitment worth understanding fully before signing.

Before committing to any provider, confirm it is a registered financial service provider on New Zealand’s Financial Service Providers Register and that it belongs to an approved dispute-resolution scheme. Bank facilities come with that assurance automatically; with non-bank and fintech lenders it is worth checking, because the market includes everything from well-established specialists to high-cost short-term operators. A registered, reputable lender should set out all fees, the total cost and the repayment schedule clearly and in writing.

Common mistakes and improving the underlying cash flow

Finance is a tool, not a cure. The businesses that use it best also work on the cash flow that created the need in the first place, so they borrow by choice rather than necessity. The most common mistakes are borrowing to cover a structural loss rather than a timing gap; focusing on the weekly repayment instead of the total cost; taking a facility that is larger than needed and paying fees on the unused portion; and relying on expensive short-term finance as a permanent fixture. Alongside any facility, the practical levers that reduce the need to borrow include:

• Invoice promptly and accurately — the clock on getting paid only starts once the invoice is out.
• Tighten payment terms and make it easy to pay, with clear due dates and simple payment methods.
• Chase overdue debtors consistently rather than letting them drift.
• Negotiate supplier terms so what you owe and what you are owed are better aligned.
• Forecast and plan for seasonal dips and known lumpy costs such as tax, instead of being surprised by them.
• Keep a cash reserve where possible, so small shocks do not automatically mean borrowing.

Free, independent help is available through business.govt.nz and the Regional Business Partner Network, and an accountant or business adviser can help you model your cash flow and decide whether finance is the right answer at all.

The bottom line

Working capital finance is about timing rather than survival: it bridges the gap between money going out and money coming in, so a profitable business is not tripped up by its own billing cycle. Bank overdrafts and revolving credit facilities are the cheapest options for ongoing, flexible needs; invoice finance suits businesses held up by large, slow-paying invoices; and short-term loans offer speed for urgent one-offs at a higher price. Match the product to the specific problem, compare the true cost rather than the headline rate, and keep working on the underlying cash flow so you borrow because it is the smart choice, not because you have run out of room.

Frequently asked questions (FAQ)

What is working capital finance?

It is short-term funding that helps a business cover day-to-day running costs — payroll, suppliers, stock and tax — when cash flow is tight, particularly in the gap between invoicing a customer and being paid. The main options in New Zealand are business overdrafts, revolving credit facilities, invoice finance and short-term business loans.

What is the difference between an overdraft and a revolving credit facility?

Both let you draw down and repay flexibly, paying interest only on what you use. An overdraft is usually smaller and attached to your business bank account, making it ideal for everyday smoothing. A revolving credit facility tends to be larger, more structured and often secured against property or assets, which makes it cheaper per dollar and better suited to bigger SMEs with substantial, reusable funding needs.

How does invoice finance work?

Invoice finance lets you borrow against unpaid invoices. A lender advances a large portion of an invoice’s value straight away — typically around 70% to 90% — then releases the balance, minus its fees, once your customer pays. It suits businesses that issue sizeable invoices to creditworthy customers on 30 to 90 day terms and are held up by slow payment.

How much does working capital finance cost?

It depends on the product, your security and your trading history. As a broad guide, bank overdrafts tend to sit in the low-to-high teens once the base rate and margin combine, secured revolving credit is cheaper, invoice finance is charged as a percentage of invoice value per period, and unsecured short-term loans cost considerably more. These are indicative figures only — confirm current rates and fees with the lender and always compare the total cost of borrowing in dollars.

Should I use finance or just fix my cash flow?

Ideally both. Finance is a useful tool for genuine, temporary timing gaps, but it costs money, so alongside it you should improve the underlying cash flow — invoicing promptly, tightening payment terms, chasing debtors and planning for seasonal dips. That reduces how often you need to borrow. Free help is available through business.govt.nz and the Regional Business Partner Network.

Working capital finance helps New Zealand businesses manage the money they need to run day to day — covering wages, suppliers, rent, stock and tax while they wait to be paid by their own customers. For many Kiwi firms, reliable access to short-term cash is every bit as important as long-term investment or growth funding, because even a profitable business can be caught out when money goes out the door faster than it comes in. This guide explains what working capital is, the main finance options available in New Zealand, roughly what each costs, how to choose between them and when a business actually needs them. It is general information about the market, not financial advice or a recommendation of any lender or product.

What working capital finance is

Working capital is the money a business has available to meet its short-term obligations. In accounting terms it is your current assets (cash, stock and money owed to you by customers) minus your current liabilities (money you owe to suppliers, staff, the bank and Inland Revenue in the near term). When that number is healthy, you can pay your bills comfortably as they fall due. When it is tight, you feel the squeeze — even if the business is winning plenty of work and turning a profit on paper.

The reason the squeeze happens is the cash-flow cycle: the gap between spending money to deliver a product or service and actually collecting the cash for it. A builder buys materials and pays a crew this week, but the client might not settle the invoice for 30, 60 or even 90 days. A retailer pays for stock before the season starts and only recovers it as goods sell. That timing gap is where working capital finance comes in — it bridges the space between money going out and money coming in, so the day-to-day running of the business is not held hostage by its billing calendar.

Importantly, working capital finance is about timing, not rescue. It is designed to smooth a genuine, temporary gap in a viable business. It is not a sensible long-term fix for a business that consistently spends more than it earns — in that situation, borrowing simply adds interest to a deeper problem that needs solving at its root.

Watch for establishment or application fees, annual or line fees charged on your total limit (not just what you draw), management or service fees on invoice finance, early-repayment costs, and how interest is calculated — daily on the drawn balance is normal and fair for a revolving facility. Because a short-term loan is repaid over a short period, a seemingly small weekly fee can translate into a very large annualised cost, so always compare the total cost of borrowing in dollars, not just the advertised rate. Our guide to understanding loans walks through how rates, terms and fees combine into the true cost.

When a business needs working capital finance

The need almost always comes down to a timing mismatch between outgoings and income. Common triggers include:

• Seasonal cash-flow gaps — retailers stocking up before Christmas, or farmers covering costs between one harvest or payout and the next.
• Rapid growth that outpaces invoice collection, where winning more work means paying for more labour and materials before the money lands.
• Slow-paying customers, particularly large corporates and government agencies that pay to their own schedule rather than yours.
• Unexpected costs such as an equipment breakdown, an insurance excess, a compliance bill or a tax payment falling at an awkward time.
• A large new contract that requires significant upfront stock, materials or staffing before the first payment is received.

In each case the business is fundamentally sound — the problem is purely one of timing. That is exactly where short-term finance earns its keep. Where it does not help is in propping up a business whose costs structurally exceed its income; borrowing there only delays and deepens the issue, and the underlying numbers need to be fixed first.

How to choose the right option

The right product depends on the nature of your cash-flow gap rather than simply the cheapest headline rate. A revolving, unpredictable need — a buffer that rises and falls month to month — usually suits an overdraft or revolving credit facility, because you pay interest only on what you use and the facility stays in place for whenever you need it. A gap caused specifically by slow-paying customers points to invoice finance, which releases money you have genuinely already earned and grows with your sales. A one-off, urgent, short-lived need might justify a short-term loan, accepting a higher cost in exchange for speed. And a need tied to card-based sales might fit a merchant cash advance.

Whichever direction you lean, run the same checks: compare the total cost across at least two or three lenders; read the fine print on fees, limit reviews and early-repayment terms; and make sure the repayment pattern genuinely matches your cash-flow cycle, so repayments fall due around when money actually comes in rather than before it. Since GST timing is one of the most common cash-flow pressures for NZ businesses, it is worth setting money aside ahead of each return — our GST guide and calculator can help you plan for it.

Secured vs unsecured, and checking the lender

Working capital finance can be secured (backed by an asset such as property, the business’s debtors or a general security agreement) or unsecured (based on your trading record and cash flow alone). Secured facilities almost always carry lower rates and larger limits because the lender’s risk is reduced, but they put an asset at stake. Unsecured facilities are faster and keep your assets free, but cost more and tend to be smaller. Many business owners are also asked for a personal guarantee, which makes them personally liable if the business cannot repay — a significant commitment worth understanding fully before signing.

Before committing to any provider, confirm it is a registered financial service provider on New Zealand’s Financial Service Providers Register and that it belongs to an approved dispute-resolution scheme. Bank facilities come with that assurance automatically; with non-bank and fintech lenders it is worth checking, because the market includes everything from well-established specialists to high-cost short-term operators. A registered, reputable lender should set out all fees, the total cost and the repayment schedule clearly and in writing.

Common mistakes and improving the underlying cash flow

Finance is a tool, not a cure. The businesses that use it best also work on the cash flow that created the need in the first place, so they borrow by choice rather than necessity. The most common mistakes are borrowing to cover a structural loss rather than a timing gap; focusing on the weekly repayment instead of the total cost; taking a facility that is larger than needed and paying fees on the unused portion; and relying on expensive short-term finance as a permanent fixture. Alongside any facility, the practical levers that reduce the need to borrow include:

• Invoice promptly and accurately — the clock on getting paid only starts once the invoice is out.
• Tighten payment terms and make it easy to pay, with clear due dates and simple payment methods.
• Chase overdue debtors consistently rather than letting them drift.
• Negotiate supplier terms so what you owe and what you are owed are better aligned.
• Forecast and plan for seasonal dips and known lumpy costs such as tax, instead of being surprised by them.
• Keep a cash reserve where possible, so small shocks do not automatically mean borrowing.

The bottom line

Working capital finance is about timing rather than survival: it bridges the gap between money going out and money coming in, so a profitable business is not tripped up by its own billing cycle. Bank overdrafts and revolving credit facilities are the cheapest options for ongoing, flexible needs; invoice finance suits businesses held up by large, slow-paying invoices; and short-term loans offer speed for urgent one-offs at a higher price. Match the product to the specific problem, compare the true cost rather than the headline rate, and keep working on the underlying cash flow so you borrow because it is the smart choice, not because you have run out of room.

Frequently asked questions (FAQ)

What is working capital finance?

It is short-term funding that helps a business cover day-to-day running costs — payroll, suppliers, stock and tax — when cash flow is tight, particularly in the gap between invoicing a customer and being paid. The main options in New Zealand are business overdrafts, revolving credit facilities, invoice finance and short-term business loans.

What is the difference between an overdraft and a revolving credit facility?

Both let you draw down and repay flexibly, paying interest only on what you use. An overdraft is usually smaller and attached to your business bank account, making it ideal for everyday smoothing. A revolving credit facility tends to be larger, more structured and often secured against property or assets, which makes it cheaper per dollar and better suited to bigger SMEs with substantial, reusable funding needs.

How does invoice finance work?

Invoice finance lets you borrow against unpaid invoices. A lender advances a large portion of an invoice’s value straight away — typically around 70% to 90% — then releases the balance, minus its fees, once your customer pays. It suits businesses that issue sizeable invoices to creditworthy customers on 30 to 90 day terms and are held up by slow payment.

How much does working capital finance cost?

It depends on the product, your security and your trading history. As a broad guide, bank overdrafts tend to sit in the low-to-high teens once the base rate and margin combine, secured revolving credit is cheaper, invoice finance is charged as a percentage of invoice value per period, and unsecured short-term loans cost considerably more. These are indicative figures only — confirm current rates and fees with the lender and always compare the total cost of borrowing in dollars.

Should I use finance or just fix my cash flow?

Ideally both. Finance is a useful tool for genuine, temporary timing gaps, but it costs money, so alongside it you should improve the underlying cash flow — invoicing promptly, tightening payment terms, chasing debtors and planning for seasonal dips. That reduces how often you need to borrow. Free help is available through business.govt.nz and the Regional Business Partner Network.
