For a lot of Australian SMEs, finding work isn’t the hard part, and neither is doing it. The hard part is getting paid on time. You finish the job, send the invoice, and then you wait. Thirty days if you’re lucky, sixty if you’re not, sometimes longer. Your costs don’t wait with you. Wages go out, suppliers want paying and materials still need buying, whether or not your customer has got around to your invoice.
That gap between doing the work and getting the cash is one of the most common pressure points for growing businesses, and it’s a big reason debtor finance has become so widely used across Australia. It lets you draw on the money sitting in your unpaid invoices, so your cash flow follows your work instead of your customers’ payment habits.
Debtor finance is also widely misunderstood. Plenty of people assume it’s a loan, or that it’s only for businesses already in trouble. Neither is quite right. In this post, OptiPay explains how debtor finance works, who tends to use it and what to weigh up before you do.
Why this is useful
If cash flow keeps you guessing, it’s hard to plan anything. Should you take on that bigger contract? Hire another person? Buy materials in bulk while the price is good?
Knowing how debtor finance works means you can answer those questions based on the work you have coming in, not on when a customer’s payment might land.
It’s one of the more practical tools an SME can have in its back pocket, and it makes more sense to understand it before you’re desperate for cash.
What debtor finance actually is
Debtor finance lets you get most of the value of an invoice upfront instead of waiting for your customer to pay. With OptiPay, that’s up to 90% of the invoice, paid within 24 hours of approval. When your customer pays, you receive the balance, minus an agreed fee.
Say you invoice a customer $50,000 on 60-day terms. Instead of waiting two months, you could have $40,000 in your account within about 24 hours of approval. The other, less the fee, arrives when the customer pays.
Unlike a bank loan, it’s tied to invoices you’ve already raised rather than your property, and there’s no fixed repayment schedule. That’s why the requirements look different too.
How debtor finance works in practice
The process is simple; you do the work and send your invoice as usual. OptiPay checks your customer’s credit rating and verifies the invoice, then pays you up to 90% of its value, usually within 24 hours of approval. When your customer pays, you receive the remaining balance, less the agreed fee.
You can put that cash straight toward wages, suppliers or materials. You also choose which invoices to fund, so you can use it only when you need it. Because you know roughly when the money is coming, planning your week gets a lot easier.
Why businesses use debtor finance
The businesses that get the most out of debtor finance tend to be growing quickly, or dealing with busy and quiet patches. A new contract means buying materials and paying staff upfront, and plenty of owners don’t want to drain their reserves to do it. Others use it simply to take the guesswork out of the month.
It’s especially common in industries where long payment terms are normal and upfront costs are high, like construction, labour hire, manufacturing, transport, professional services and wholesale. A transport company is a good example. Fuel and driver wages are due this week, but the payment for those runs might not arrive for two months.
The difference between debtor finance and traditional lending
Banks look at your financial history, property security, credit scores and long-term performance. Approvals can take weeks, and limits can be conservative, which is a poor fit for a business that’s growing faster than its history shows.
Debtor finance is based on your invoices and your customers’ credit. If you’ve done the work and raised the invoice, that’s what counts, and you don’t need to put up property as security. There’s still an assessment, but it’s built around your invoices and your customers rather than your assets. It also flexes with you: the more you invoice, the more you can draw.
Growing without a loan
Because you’re drawing on money you’ve already earned, there are no interest repayments and no repayment schedule to keep up with. OptiPay charges a pre-agreed fee on the invoices you fund, and only when your customer pays. That means you can hire, buy materials, invest in equipment or take on a new contract without adding a loan repayment on top of everything else.
What cash flow pressure does to owners
Cash flow pressure changes how you make decisions. You hesitate on things that should be simple, you put off hiring, second-guess a quote, or lie awake wondering whether a big customer will pay on time. When you’re waiting on payments, every choice feels heavier than it should.
Knowing the cash will be there takes a lot of that weight off. You get to think about the business instead of the bank balance.
Protecting customer relationships
Nobody enjoys chasing a customer for money, especially one you want to keep working with. Debtor finance means you don’t have to lean on them for faster payment or push for shorter terms just to keep cash moving. Your customer keeps their usual payment terms, and you still get access to the cash.
That matters most for SMEs that rely on trust and long-term relationships.
Is debtor finance right for you?
Debtor finance isn’t for everyone. It suits businesses that invoice other businesses and it won’t fix a business that isn’t making money.
But if you’re doing good work, your customers are good for it and the only problem is timing, it’s one of the most practical cash flow tools.
Blog in summary
Debtor finance lets you get paid early on invoices you’ve already raised, so cash arrives when your costs do rather than when your customers get around to paying. You keep growing without taking on a loan, and you know what you’ll have to work with each week. To see whether it suits your business, get in touch with OptiPay.
Frequently asked questions
Is debtor finance only for businesses in trouble?
Not at all. Plenty of profitable, fast-growing businesses use it because their customers pay on 30 to 90 day terms and their costs don’t wait. It’s also used to cover seasonal swings and to bridge the gap after a tough trading period.
How much of an invoice can I get upfront, and how fast?
With OptiPay, you can get up to 90% of an invoice’s value within 24 hours of approval. The remaining balance, less the agreed fee, is paid when your customer settles the invoice.
What does debtor finance cost?
OptiPay doesn’t charge application or set-up fees. You pay an agreed discount fee on the invoices you fund, and only when your customer pays them. There are no interest repayments, and the fee can come down as you fund more invoices, so it’s worth asking for a quote.
Who can use debtor finance?
It suits businesses that invoice other businesses. OptiPay works with businesses turning over $1 million or more a year, with facilities from $100,000 up to $10 million, and no property security is required. You’ll still go through an assessment, but it centres on your invoices and your customers’ credit rather than your assets.
