How Invoice Finance Works

Invoice finance works by turning your unpaid sales invoices into cash you can use now instead of waiting 30, 60, or 90 days to be paid. You raise an invoice to a business customer as normal; the lender advances a percentage of its value, usually 80% to 90%, within a day or so of verifying it; then when your customer pays, the lender releases the remaining balance to you, minus their fee. These figures are indicative and vary by lender, sector, and the strength of your debtor book. The exact advance rate is set by the lender once they have seen your ledger, not fixed in advance.

The mechanism matters because it is a rolling facility, not a one-off loan. As you invoice more, more funding becomes available; as invoices are paid, the facility resets and frees up headroom against the new invoices you raise. That is the core reason growing businesses reach for it: the funding line scales with your sales ledger rather than being a fixed lump sum you have to reapply for. It is designed to smooth cash flow when your money is tied up in the gap between delivering work and getting paid.

What the lender is really underwriting is your debtors, not just you. They will look at who owes you money, how spread out those debts are, and how reliably those customers pay. A ledger with one customer accounting for most of your turnover carries debtor concentration risk, so lenders often cap the percentage they will fund against any single debtor (a limit of around 30% to 50% of the ledger is common, though this is illustrative and set case by case). A broad spread of solid, creditworthy customers reads far better than a handful of large but shaky ones.

Verification is the step people underestimate. Before advancing, the lender checks that the invoice is genuine, that the goods or services were actually delivered, and that the debtor accepts the debt. Depending on the facility this can be a light touch or a direct confirmation with your customer. Poorly documented invoices, disputes, or contra-trading (where a customer also sells to you) can all reduce or block an advance, because the lender needs to be confident the debt is clean and collectable.

A key fork is recourse versus non-recourse. With recourse finance (the more common and usually cheaper option), if your customer does not pay, you carry that risk and have to repay the advance on that invoice. With non-recourse, the lender absorbs an agreed level of bad-debt risk, often via credit insurance, which typically means a higher fee and tighter debtor vetting. Non-recourse protects against a customer becoming insolvent, but it is not a blanket guarantee; it usually only covers approved debtors within agreed limits, and disputes are generally excluded. The right choice depends on how concentrated and how creditworthy your ledger is.

Costs generally come in two parts: a service or management fee (a percentage of turnover put through the facility) and a discount charge (interest on the funds you actually draw, usually priced over a base rate). Whether the facility is confidential or disclosed, and whether the lender handles collections, also shapes the price and the day-to-day experience. None of this is quoted meaningfully until a lender has seen your figures, so treat any headline rate you read online as a starting point, not a promise.

As a broker, our job is to work out which lenders actually suit your sector, your debtor profile, and your typical invoice size, then place you with one that fits rather than the first that says yes. Invoice finance appetite varies a lot: some lenders like recruitment and wholesale ledgers, others avoid construction (with its stage payments and retentions) or contracts with heavy dispute risk. We match you to lenders whose criteria fit your ledger and get the facility properly structured. What we cannot do is set the advance rate or fee, or guarantee approval; the lender prices the facility and makes the decision on your specific file.
