Will Invoice Finance Eat Into My Profit Margins?
Typical cost is 1-3% of turnover. If your margins are above 10%, the cost is manageable and you probably will not feel it. If margins are below 5%, think carefully. But the real question is: what is the cost of NOT having cash? Turning down a £50,000 contract because you cannot fund delivery costs far more than the 2% you would have paid to finance it.
Quick Reference
Direct Answer
Invoice finance costs 1-3% of turnover. With margins above 10%, the impact is manageable. Below 5% margins, it requires careful consideration. However, the cost should be weighed against alternatives: turning down work, late supplier payments, payroll stress, or overdraft fees.
Summary
The margin impact depends on how the facility is used. Businesses using invoice finance to fund growth (taking on more work) often see net margin increase because the additional revenue more than covers the financing cost. Businesses using it purely for survival may find it squeezes already-thin margins. The key metric is return on the funded amount, not the cost in isolation.

The Hidden Costs of NOT Having Cash
Before worrying about the 1-3%, consider what poor cash flow already costs you. Late supplier payments mean no early payment discounts (often 2-5%). Turning down contracts because you cannot fund delivery. Emergency borrowing at higher rates. Payroll anxiety every month. Damaged supplier relationships. All of these have a cost — they are just harder to measure than a percentage on an invoice.
When It Does Not Make Sense
If your net margins are consistently below 3-5% and you are not using the facility to fund growth, the maths gets tight. Businesses in this position may be better served by renegotiating payment terms, cutting costs, or restructuring pricing — using invoice finance to paper over a fundamental margin problem just delays the reckoning.
The Growth Scenario
Where invoice finance really pays for itself is growth. You win a £200,000 contract with 15% margin (£30,000 profit). You need £80,000 upfront for materials and wages. Invoice finance costs you roughly £3,000-£4,000 on that contract. You still make £26,000 profit. Without the facility, you would have made £0 because you could not take the work on.
