Small and medium-sized enterprises (SMEs) in New Zealand often use bank overdrafts to manage short-term cash flow. For some businesses, that works well for a time.

But as a business grows, an overdraft can start to feel restrictive. Larger customers, longer payment terms and more complex supply chains can all create cash flow gaps that a fixed overdraft limit may not be able to cover.

Invoice Finance works differently. It allows businesses to access working capital tied up in unpaid invoices, rather than waiting 30, 60 or 90 days for customers to pay.

For businesses involved in importing or exporting, the timing gap can be even more pronounced. Stock may need to be paid for before it arrives, and customer payment may not come through until weeks or months later. ScotPac’s Trade Finance facilities can work alongside Invoice Finance to help bridge the gap between supplier payments and customer receipts.

Why are New Zealand SMEs outgrowing their bank overdrafts?

For many New Zealand small and medium-sized businesses, a bank overdraft is a familiar cash flow tool. It is usually connected to existing business banking arrangements and can provide access to extra funds when cash is tight.

But as SMEs grow, the structure of an overdraft can become limiting.

An overdraft usually provides access to a fixed limit. That limit is typically based on the lender’s assessment of the business, its credit profile and available security. It does not automatically increase just because your sales are growing or your invoice values are getting larger.

That can become a problem when a major customer stretches payment terms to 60 or 90 days, or when a business needs to fund stock, wages or supplier payments before customer cash comes in.

For New Zealand importers and exporters, the pressure can be even greater. You may need to pay an overseas supplier before goods arrive in New Zealand, then wait again before your own customers pay you.

Invoice Finance is designed around that timing gap. Instead of relying on a fixed overdraft limit, it allows your business to access funding linked to unpaid customer invoices. As your eligible invoice volume grows, your available funding can grow too, subject to facility terms.

How does Invoice Finance work for New Zealand businesses?

Invoice Finance, also called Debtor Finance, allows a business to unlock the value of unpaid invoices without waiting for customers to pay.

Here’s how it generally works.

Issue an invoice 

You issue an invoice to your customer for the goods or services you have delivered.

Submit your invoice 

You submit the invoice to ScotPac. Once your facility is approved and set up, ScotPac can advance an agreed percentage of the invoice value, often within 24 hours.

Invoice is paid 

Your customer pays the invoice on their normal payment terms.

Receive the balance 

You receive the remaining balance, less applicable fees.

The result: your cash flow is more closely aligned to your sales activity, not your customers’ payment schedules.

Unlike a bank overdraft, Invoice Finance is linked to your unpaid invoices. That means your funding capacity can reflect the value of eligible invoices you are issuing, rather than being limited to a fixed overdraft amount.

How does Invoice Factoring differ from Invoice Discounting?

There are two types of invoice finance:

  • Invoice Factoring
  • Invoice Discounting
How does Invoice Factoring work?

With Invoice Factoring, your finance provider manages receivables and collections on your behalf.

This can reduce the administrative burden on your business, especially if you do not have a dedicated accounts receivable team. It also usually means your customers are aware a finance provider is involved.

How does Invoice Discounting work?

With Invoice Discounting, your business continues to manage customer relationships and collections in-house.

This can be a better fit for businesses with established accounts receivable processes that want to keep the arrangement confidential from customers.

Should you replace your overdraft with Invoice Finance?

Not every business needs to replace its overdraft. For some SMEs, an overdraft may still be useful for short-term or occasional cash flow needs.

But if your overdraft limit is no longer keeping pace with sales, or if customer payment terms are making it harder to fund growth, Invoice Finance may be worth considering. It can be particularly useful where your business has strong sales, reliable customers and cash tied up in unpaid invoices.

FAQs: Invoice Finance vs Overdraft for New Zealand SMEs

What is the main difference between Invoice Finance and a bank overdraft in New Zealand?

A bank overdraft gives your business access to a fixed credit limit. 

Invoice Finance gives your business access to funding linked to unpaid invoices. This means available funding can grow as your eligible invoice volume grows, subject to facility terms.  

What do New Zealand SMEs need to qualify for Invoice Finance?

To qualify for invoice finance, you will need to: 

  • invoice other businesses, rather than sell directly to consumers 
  • trade on standard payment terms 
  • have creditworthy debtors 
  • have been in operation for at least 6 months 
  • demonstrate consistent invoicing and collections 
  • meet ScotPac’s minimum monthly invoice requirements 
  • be registered and operating in New Zealand, with invoices issued in New Zealand dollars  

Is Invoice Finance more expensive than an overdraft?

Not necessarily. The cost depends on the structure of the facility, your invoice terms, debtor risk and the level of support required. 

An overdraft usually charges interest on the drawn balance and may involve fees or security requirements. 

Invoice Finance is priced differently and may include facility or service fees. For some businesses, the value comes from accessing cash earlier, reducing debtor pressure, paying suppliers sooner or taking on more work without waiting for invoices to be paid. 

A ScotPac specialist can help you compare the costs and benefits based on your business. 

Will my customers know I'm using invoice finance?

That depends on the facility structure. 

With Invoice Factoring, where ScotPac supports receivables and collections, customers are usually aware of the arrangement. 

With Invoice Discounting, your business continues managing collections and the arrangement can remain confidential.  

How quickly can I access funds through Invoice Finance compared to an overdraft?

Once an Invoice Finance facility is approved and set up, funds from eligible invoices can typically be accessed quickly, often within 24 hours. 

An overdraft facility, once set up, is accessible immediately but only up to the agreed limit. 

The difference is that an overdraft is limited to a fixed amount, while Invoice Finance is linked to the eligible invoices your business is issuing
