What Is the True Cost of Invoice Finance?
The headline service charge (0.5-3% of turnover) is only part of the cost. Add the discount charge (base rate + 2-5% on drawn balance), arrangement fee (0.5-1.5% year one), minimum monthly charge, audit fees (£4,000-£8,000 per visit), and CHAPS fees. Total annual cost typically runs 1.5-5% of turnover depending on facility size and provider.
What this means for your business
When UK businesses consider invoice finance, the headline service charge is often the first number quoted, but it rarely tells the whole story. In practice, the total cost combines several layers of fees that accumulate over a year. The service charge, typically between 0.5% and 3% of turnover, covers the administration of the facility. On top of this, a discount charge applies to the funds you actually draw down, calculated at a margin above the Bank of England base rate. Then there are one-off and periodic costs such as the arrangement fee in year one, scheduled audit visits, and transaction fees like CHAPS payments. When all these elements are added together, most UK businesses find their all-in annual cost falls somewhere between 1.5% and 5% of turnover, depending on their facility size, sector, and chosen provider.
Key points
- The service charge of 0.5% to 3% of turnover is the most visible fee but is not the only one you will pay.
- A discount charge, typically set at base rate plus 2% to 5%, is applied to the balance of funds you have drawn at any given time.
- An arrangement fee of 0.5% to 1.5% is commonly charged in the first year when setting up the facility.
- Audit fees, which can range from £4,000 to £8,000 per visit, are charged by the funder to inspect your sales ledger and are often overlooked during initial comparisons.
- Minimum monthly charges mean that businesses with lower invoice volumes may pay proportionally more than the headline rate suggests.
Common pitfalls
One of the most common mistakes is comparing providers on service charge alone, without requesting a full fee schedule. Businesses often underestimate how frequently audits are conducted and how quickly those costs accumulate, particularly in the first year of a facility. Minimum monthly charges can catch lower-turnover businesses off guard, effectively raising the true cost significantly above the quoted rate. It is also worth checking whether CHAPS and same-day transfer fees apply each time you draw funds, as frequent drawdowns can make these transaction costs a meaningful line item over a full year.
Related questions
How does the discount charge on invoice finance actually work?
The discount charge is interest applied to the amount of money you have drawn from your facility, calculated daily and charged monthly. It is expressed as the Bank of England base rate plus a fixed margin, usually between 2% and 5%, so the total rate you pay will move when the base rate changes. You only pay this charge on funds you have actually drawn, not on the full value of invoices you have uploaded.
Are invoice finance audit fees negotiable?
Audit fees are sometimes negotiable, particularly for larger facilities or businesses that can demonstrate strong credit controls and clean ledger management. Some providers bundle a set number of audits into the annual fee, while others charge separately for each visit. It is worth asking for clarity on the frequency and cost of audits before signing any agreement, as these fees can add several thousand pounds to your annual cost.
What is a minimum monthly charge and how does it affect smaller businesses?
A minimum monthly charge is a floor set by the provider, meaning you will pay at least that amount each month regardless of how many invoices you raise or how much of the facility you use. For businesses with seasonal turnover or lower invoice volumes, this can push the effective percentage cost well above the quoted service charge. Comparing the minimum monthly charge against your expected average monthly usage is an important step before committing to a facility.
