Most SMEs use one or two finance tools and wonder why they still have cashflow timing problems. This article compares invoice finance, overdrafts, BNPL, and trade finance side by side, explains when each tool is the right fit, and shows where invoice finance fills the gap most businesses are missing.

Why most SMEs use the wrong tool for their cashflow timing problem
[Write: Most SMEs default to an overdraft for cashflow problems. The overdraft is familiar, easy to access if you have a banking relationship, and flexible. But it has a fixed limit that doesn't scale with revenue. A business growing 30% year-on-year needs 30% more cashflow buffer, but the overdraft limit stays the same until the annual review. Invoice finance is the product that scales with revenue, but most SMEs don't know it exists or think it's only for large businesses.]
The comparison: invoice finance vs overdraft vs BNPL vs trade finance
| Invoice finance | Overdraft | B2B BNPL | Trade finance | |
|---|---|---|---|---|
| What it funds | Unpaid invoices (receivables) | Any short-term need | Supplier purchases (payables) | Import/export transactions |
| Cost | 4-6% per invoice (FundTap) | 8-15% p.a. on balance | Varies | Varies |
| Speed | Same day (before cut-off) | Available on draw | Immediate on purchase | Days to weeks |
| Scales with revenue? | Yes | No (fixed limit) | Depends on provider | No |
| Security | Invoice as collateral | May need property | Usually none | Letter of credit / insurance |
| Best for | B2B businesses waiting on invoices | Short-term buffer, irregular needs | Businesses buying on terms | Import/export businesses |
| AU/NZ availability | Yes | Yes | Emerging | Yes |
When each tool is the right fit
[Write: Invoice finance: B2B businesses, wait 20-60 days for payment, have regular costs before payment arrives. Overdraft: irregular needs, businesses that don't invoice, or as a secondary buffer alongside invoice finance. B2B BNPL: businesses that buy from suppliers on credit terms and want to extend their payment window. Trade finance: importers/exporters managing cross-border payment risk. Most SMEs don't need trade finance.]
Why most businesses benefit from two or three tools, not one
[Write: Invoice finance handles receivables. Overdraft handles irregular short-term needs. BNPL handles payables. A business can use invoice finance to fund outstanding invoices while maintaining an overdraft as a buffer for unexpected costs. The key is not to use the overdraft to cover cashflow timing gaps that invoice finance could solve more cheaply and at greater scale.]
Where invoice finance sits in a typical SME finance stack
[Write: The typical SME finance stack: a transaction account, a business credit card, and an overdraft. Invoice finance is the missing piece that most growing B2B businesses are not using. It is not a replacement for the overdraft. It is the layer that handles the receivables gap so the overdraft can handle unexpected costs.

How to evaluate your current finance stack
[Write: Three questions: (1) Do you invoice other businesses and wait to be paid? If yes, you probably need invoice finance. (2) Is your overdraft limit keeping up with your revenue growth? If no, you need a facility that scales. (3) Are you using a personal credit card to cover business cashflow? If yes, this is the most expensive and least scalable option in the stack. Invoice finance is almost certainly cheaper and more appropriate.]
Frequently asked questions
What is the difference between invoice finance and a business overdraft?
An overdraft is a revolving credit facility with a fixed limit. You draw from it when needed and repay at your own pace, paying interest on the outstanding balance. Invoice finance is tied to specific invoices: you fund a specific invoice, receive an advance, and repay when your client pays. Invoice finance scales with your invoicing volume and does not usually require property security.
Is BNPL suitable for B2B businesses?
Buy now pay later products were originally designed for consumer retail. B2B BNPL products allow businesses to purchase from suppliers on deferred payment terms. This is a payable-side product: it helps you delay paying a supplier. Invoice finance is a receivable-side product: it helps you receive payment from a customer faster. They solve different problems and can work together.
What is trade finance and how is it different from invoice finance?
Trade finance covers products designed to facilitate import and export transactions, including letters of credit, trade credit insurance, and supply chain finance. Invoice finance is simpler: it is an advance on a domestic invoice. Most SMEs do not need trade finance unless they are importing or exporting.
Can a business use invoice finance and an overdraft at the same time?
Yes. Most SMEs that use invoice finance also maintain an overdraft or another credit facility. Invoice finance handles the receivables gap. An overdraft handles unexpected short-term needs. Using both is common and appropriate.
How much does invoice finance cost compared to an overdraft?
Invoice finance is priced as a percentage of each invoice funded, typically 4 to 6% at FundTap. An overdraft is priced as interest on the balance drawn, typically 8 to 15% per annum. For a business that draws on invoice finance for 30 to 45 days per invoice, the cost is often comparable to or lower than an overdraft on the same amount for the same period, with the added benefit that invoice finance scales with revenue.
