What is debtor finance?
Debtor finance is a way to draw cash from the money your customers already owe you, rather than waiting the full term for them to pay. Your unpaid invoices — the amounts your "debtors" (the customers you have billed) still have to settle — become the thing the funding is built around.
In practice, a finance provider advances you a portion of an invoice soon after you raise it, and you receive the rest, less a fee, once the customer pays. It is designed to smooth the gap between doing the work and getting paid for it.
Why can it work when a bank overdraft cannot?
Debtor finance is assessed largely on the creditworthiness of the customers you invoice, not the property you own. That is the key difference. A traditional overdraft often wants real estate as security, so a growing business without a house or commercial premises behind it can find the door closed.
With debtor finance, the focus shifts to a few things:
- Who your customers are and how reliably they pay
- The quality and spread of your invoice book
- Whether the work has genuinely been delivered and can be billed
So a business with no real estate security but solid commercial debtors may still qualify, depending on your circumstances.
What is the difference between factoring and invoice finance?
Factoring and invoice finance both release cash tied up in unpaid invoices, but they differ in who chases payment and who knows about it. Under factoring, a factor company buys your outstanding invoices at a discount and then chases the debtors itself, and the customer pays the factor directly. It is a quick way to get cash, but it can be expensive compared with traditional financing options.
Invoice finance is structured differently. It is treated as the sale of an asset — the customer invoice and the entitlement to that payment — rather than a loan or overdraft. The invoice is still paid to your own business, and your customers are generally not made aware of the arrangement. Which one suits you may depend on how comfortable you are with a third party contacting your customers.
"If your customers pay their bills, that track record can do more work for you than the bricks and mortar on your balance sheet"
— Moishe Weiss, Finance Writer, Wood & WeissWhy do slow payment times matter so much?
Slow-paying customers are a common reason a profitable business still runs short of cash. Reported data for 1 January to 30 June 2025 showed the average time a large business took to pay 95% of its small business invoices rose to 64 days, up from 58 days in the previous cycle. That is roughly two months of your money sitting on someone else's balance sheet.
For context, to be counted as a fast small business payer, a large business must pay 95% or more of its small business invoices in 20 days or less across two consecutive reporting periods. There is also a public tool that can help you before you extend terms: payment times reports for the period ended 30 June 2026 are due by 30 September 2026, and the register is publicly searchable, so you can check how a prospective customer tends to pay.
What should I weigh up before using it?
Debtor finance is convenient, but it can cost more than a traditional overdraft, so the price of speed is the first thing to weigh. Fees are usually charged as a percentage of invoice value plus a funding cost, and they add up if your customers are slow.
A few practical questions worth asking:
- Do you want customers contacted directly, or kept out of it?
- Is the cost worth it against the value of getting paid sooner?
- Are your invoices clean, undisputed and clearly owed?
None of this is one-size-fits-all, and the right answer could change as your business grows.
The bottom line
The bottom line is that debtor finance can suit a business that is cash-tight but has strong, reliable customers and little or no property to offer as security. It is general information, not advice, and whether it fits depends on your circumstances, your margins and how patient your customers are. If waiting on invoices is holding you back, it is worth understanding the trade-off between speed and cost before you commit.
Common questions
Do I need to own property to qualify?
Not necessarily. Debtor finance is assessed largely on the strength of your customers and your invoices rather than real estate, so a business without property security may still qualify depending on its circumstances.
Will my customers know I am using it?
It depends on the structure. Under factoring the customer pays the factor directly, so they are aware, whereas under invoice finance the invoice is paid to your own business and customers are generally not made aware.
Is debtor finance the same as a loan?
No. Invoice finance is treated as the sale of an asset — the invoice and the right to that payment — rather than a loan or overdraft, which is a different arrangement legally and practically.
Can I check how a customer pays before offering them terms?
Often yes. The payment times register is publicly searchable, so suppliers can look up how a prospective large-business customer tends to pay before extending credit terms.
Is it more expensive than an overdraft?
It can be. Factoring in particular is a quick way to get cash but may be expensive compared with traditional financing options, so it is worth comparing the cost against the value of being paid sooner.
Worth a conversation?
