Invoice Finance for Small Business: How It Works and Costs

You sent the invoice on 30 day terms. It is day 45, nobody is disputing anything, and your customer pays when they pay, while wages, materials and fuel come from your own account. Invoice finance for small business exists for that gap: it turns an invoice you have issued into cash now, and settles the rest when the customer pays.

The gap between your terms and when you actually get paid

The Payment Times Reporting Regulator collects payment data from Australia's largest businesses. Its August 2026 update, covering the six months to 31 December 2025, put the average common payment term across all industries at 29 days, the average payment time at 27.2 days and the median at 22 days. On those numbers the typical invoice is not the problem.

The problem is the tail. Reaching 95 per cent of small business invoices paid took 55 days across all industries. In construction, where reporting entities offered average terms of 33 days, that measure was 62 days, and in professional, scientific and technical services it was 64 days against terms of 27 days.

Across all industries, 69.8 per cent of small business invoices were paid within 30 days, which leaves close to a third of them sitting longer.

That is the shape of the problem for most small businesses. Most of the ledger behaves, and a slice of it sits out past 60 days while your own costs keep their schedule. Invoice finance exists for that slice.

How invoice finance for small business actually works

Invoice finance advances you most of the value of an invoice you have already issued, then settles the balance when your customer pays. The invoice is the security, so the facility moves with your sales ledger rather than being capped by the equity you can pledge.

As at September 2026, advance rates sit around 80 per cent of eligible invoice value, and up to 90 per cent on some ledgers. NAB publishes up to 85 per cent on its invoice and debtor finance page, and the specialist lender Earlypay advances 80 per cent and says it can stretch to 90. The remainder, less fees, is released once the invoice is paid.

It is not a term loan. You are not borrowing against a forecast, you are drawing against work already delivered and invoiced. That distinction is why a business with a thin balance sheet but solid customers can sometimes qualify when a traditional business loan will not stretch.

Factoring or discounting: the difference your customers notice

Invoice factoring means you sell the invoice. The financier owns the debt and usually collects directly from your customer, so the arrangement is disclosed. business.gov.au describes factor companies as buying a business's outstanding invoices at a discount and then chasing the debtors, and notes it is quick cash that can be expensive compared with traditional finance.

Invoice discounting uses the invoices as security instead. You keep the customer relationship and you keep doing the collections, and the facility is usually confidential, so your customers never see a third party on the account.

The choice is rarely about price alone. If you supply large firms with procurement teams, a disclosed facility is unremarkable. If you sell to a handful of relationship buyers who might read it as a sign of stress, confidentiality is worth paying for.

What it costs

Pricing usually combines a running charge with a fixed one. An interest or discount charge runs on the money you have drawn for as long as it is out, and a service fee is charged on the invoice value regardless of when the customer pays. The lender Moula's guide to invoice finance costs, written in 2021 and still live, puts typical service fees at 1 to 3 per cent of invoice value, uses 10 per cent a year as its indicative discount rate, and adds a separate due diligence fee on the ledger.

To put numbers on it, take a $30,000 invoice from a construction subcontractor on 30 day terms that is actually paid on day 62, the industry's 95th percentile payment time in the regulator's update. Assume an 80 per cent advance, a 1.5 per cent service fee and a 10 per cent annual discount charge.

That is about 2.9 per cent of the invoice value for 62 days of cash, or roughly 17 per cent a year if you ran the facility continuously. Treat it as an example only: the rates are assumptions, and every facility is priced on your ledger, your customers and your volumes.

Then compare it against what the money does. If the advance lets you put on a second crew, buy materials at a volume discount or stop paying your own suppliers late, the arithmetic can work. If it only funds the same trading at a higher cost, it does not.

Who it suits, and who it does not

It works best for businesses invoicing other businesses on terms, with a clean ledger and customers who pay eventually rather than never. Labour hire, transport, wholesale and manufacturing are the usual candidates, because they carry payroll and materials well before the money lands.

It is a poor fit if you invoice consumers, if you work on progress claims and retentions that get contested, or if one customer is most of your ledger. Concentration is the thing lenders look at hardest: a book where a single debtor carries most of the value is as risky for the financier as it is for you.

What to do next

Start with your own ledger. Pull an aged receivables report and work out how much sits past 60 days, which customers cause it, and what it costs you in overdraft interest or late supplier payments. Without that number you cannot tell whether a facility is worth 2 or 3 per cent of invoice value.

Then check the other side of the trade. The Payment Times Reports Register lets you look up how quickly a large customer pays its small business suppliers, which tells you whether you are dealing with one slow account or a structural gap in your trading terms. Fixing a payment culture is cheaper than financing around it.

When you compare offers, ask for the all in cost on a realistic payment profile rather than a headline rate. Ask whether the facility is disclosed or confidential, whether it covers your whole ledger or selected invoices, what happens if a customer never pays, and what it takes to exit. Subject to lender approval, terms, and conditions apply.
