Invoice finance is one of the most commonly misunderstood products in UK business lending. Not because it is complicated, but because the pricing is structured in a way that makes direct comparisons genuinely difficult. Many business owners sign up, accept the headline rate, and only later realise they are paying significantly more than they need to.
This article breaks down exactly how invoice finance facilities are priced, what the key cost components mean in practice, and what factors lenders use to set your rates.
The Two Core Charges You Will Always See
Every invoice finance facility, whether that is a full factoring arrangement or an invoice discounting line, is built around two primary charges.
The first is the service fee (sometimes called the management fee). This is charged as a percentage of your annual turnover, typically ranging from 0.5% to 3% depending on the provider, your sector, and the complexity of your debtor book. It covers the administration of the facility and, in factoring arrangements, the credit control and collections work carried out on your behalf.
The second is the discount charge. This is the interest element, applied to the funds you actually draw down. It is calculated daily on the outstanding balance and is typically expressed as a margin above the Bank of England base rate. In practice, total discount charges often sit in the range of 1.5% to 4% per annum above base rate, though this varies considerably.
Understanding that these two charges operate independently is important. A facility with a low service fee can still be expensive if the discount charge is high, and vice versa. Always model the total annual cost across both.
Additional Fees That Are Easy to Miss
Beyond the two core charges, most invoice finance facilities carry a range of secondary fees. These do not always appear prominently in a proposal, but they add up.
Common additional charges include:
- Arrangement or facility setup fees, typically a one-off cost ranging from a few hundred to several thousand pounds depending on facility size
- Minimum usage fees, charged if you do not draw down enough against the facility each month
- Same-day payment fees, applied when you request funds faster than the standard transfer window
- Credit protection or bad debt protection premiums, if you opt into a non-recourse arrangement where the lender absorbs debtor insolvency risk
- Audit fees, covering periodic reviews of your debtor book, often charged annually or half-yearly
- Exit or termination fees, which can apply if you leave before a minimum term, typically 12 months, is completed
None of these fees are inherently unreasonable, but they need to be factored into your cost calculation from the outset.
What Drives Your Rate
Lenders price invoice finance facilities based on a risk assessment of your business and your debtor book. Knowing what they are looking at helps you understand why one business pays 1% and another pays 2.5% for what looks like the same product.
Debtor concentration is one of the most significant factors. If 60% of your turnover comes from a single customer, a lender carries concentrated risk. The more spread your debtor base, the more favourably you are likely to be priced.
Sector also plays a meaningful role. Construction, recruitment, and transport businesses often face higher scrutiny due to sector-specific risks such as contractual disputes, CIS deductions, or high debtor churn. Professional services businesses with clean debtor books tend to attract tighter pricing.
Your average debtor days matter too. A business where invoices are consistently settled within 30 days is lower risk than one where debtors routinely stretch to 90 days. Lenders price for the time your money is out.
Turnover size affects pricing partly through economies of scale. Larger facilities tend to carry lower service fee percentages, though discount charges remain more closely tied to credit risk than facility size.
Finally, trading history and financial performance feed into the overall credit picture. A business with consistent profitability and clean accounts is simply less risky to lend against.
Recourse vs Non-Recourse: A Cost Decision, Not Just a Risk Decision
One choice that significantly affects total cost is whether your facility is recourse or non-recourse.
Under a recourse arrangement, if your debtor does not pay, the liability comes back to you. The lender advances funds against your invoices but does not absorb the credit risk of your customers. This is the cheaper option.
Under a non-recourse arrangement (sometimes called bad debt protection), the lender absorbs the risk of debtor insolvency. This is essentially a credit insurance wrapper built into the facility. It costs more, typically adding 0.3% to 0.8% to your overall facility cost, but it removes a meaningful risk from your balance sheet.
For businesses with customers in volatile sectors, or where a single large debtor failure could be genuinely damaging, non-recourse cover can be well worth the additional cost. For others, it is an unnecessary overhead. The right answer depends on your specific debtor profile.
Why Comparing Lenders Is Worth the Effort
The invoice finance market in the UK includes the major clearing banks, a significant number of independent specialists, and a growing fintech segment. Rates, fee structures, and credit appetites vary considerably across these providers.
A specialist lender may price a recruitment business more competitively than a clearing bank because they have deeper sector experience and a better model for the risk. Equally, a bank with an existing relationship may offer more flexible terms on a non-recourse arrangement than an independent would.
The point is that the first quote you receive is rarely the best one available. The differences in total annual cost across providers for the same facility can run to thousands of pounds, particularly on larger turnover businesses. Taking the time to see what the market will offer, ideally with the help of someone who understands how each lender prices, is straightforward common sense.
The Bottom Line
Invoice finance pricing is more layered than it appears at the proposal stage. Understanding the two core charges, knowing which secondary fees to interrogate, and recognising what drives your specific rate puts you in a much stronger position to evaluate what you are being offered. The businesses that get the best terms are almost always the ones that go into conversations informed, ask the right questions, and do not assume the first number on the table is the only one available.
