What Is the Service Charge in Invoice Finance?

The service charge is a percentage of the gross invoice value, typically 0.5-3%, charged by the provider to cover administration, credit checks, and (for factoring) credit control. It is the main visible cost. Larger facilities and better debtor quality attract lower rates. Close Brothers and Skipton offer the lowest at 0.5%.

Why This Matters

The service charge is the core cost of invoice finance, deducted from every invoice you fund. Unlike the discount charge (interest on drawn funds), the service charge applies whether you draw money or not, making it a fixed percentage overhead on your turnover. For a business invoicing £500,000 annually with a 1.5% service charge, that's £7,500 a year in fees before any borrowing costs. Understanding what drives this rate, how it's calculated, and where providers differ is critical to accurate cost comparison. The service charge covers ledgering, debtor vetting, collections (in factoring), and ongoing account management. It's almost always quoted as a percentage of gross invoice value, but the effective rate varies wildly based on facility size, debtor quality, invoice volume, and whether you're using selective or whole turnover finance. Getting this wrong can mean overpaying by thousands annually or choosing a facility that looks cheap on paper but costs more in practice.

Key Points

Service charge typically ranges from 0.5% to 3% of gross invoice value. Close Brothers and Skipton Business Finance quote from 0.5% for larger, clean facilities, while smaller businesses or higher-risk sectors may pay 2-3%.
The charge is applied to every invoice submitted, not just those you draw funds against. A £10,000 invoice at 1.5% incurs £150 in fees whether you advance 80% or nothing at all.
Larger facilities attract lower rates through volume discounts. A £2 million annual turnover facility might pay 0.75%, while a £200,000 facility from the same provider could be 2%+.
Disclosed invoice finance and factoring typically carry higher service charges (1.5-3%) because the provider handles credit control, collections, and debtor communication. Confidential facilities with minimal intervention start around 0.5-1.2%.
Service charges are invoiced monthly, calculated on that month's gross invoice submissions. If you submit £50,000 of invoices in March at 1.8%, you'll pay £900 that month regardless of payment timing.
Better debtor quality lowers the service charge. Invoicing blue-chip companies on the approved debtor list (Tesco, NHS trusts, major PLCs) can reduce rates by 0.5-1% versus mixed SME debtors.
Some providers unbundle the service charge into separate ledger fees, credit control fees, and administration charges. Always compare the total percentage, not individual line items.

Real-World Example

A Birmingham-based IT contractor invoicing £800,000 annually to corporate clients receives two quotes: Bibby Financial Services at 1.8% service charge (disclosed factoring with full collections) and Sonovate at 1.1% (confidential invoice discounting, client retains collections).

Bibby's annual service charge would be £14,400 (£800k × 1.8%), including ledgering and chasing payments. Sonovate's would be £8,800 (£800k × 1.1%), but the contractor must manage their own credit control. The contractor chooses Sonovate because their clients pay reliably within 30 days and the £5,600 annual saving covers their existing part-time bookkeeper who already handles collections.

Common Pitfalls

Comparing headline service charge rates without checking minimum monthly fees. A 0.75% rate sounds cheap, but if there's a £500 minimum and you only invoice £40,000/month, you're effectively paying 1.25%.
Ignoring the discount charge (interest) entirely. A low 0.6% service charge with 12% discount charge can cost more than 1.5% service charge with 8% discount if you routinely draw 85%+ of invoice value.
Assuming the service charge is negotiable when facility size doesn't warrant it. Providers rarely budge below 1.5% for sub-£500k turnover facilities because fixed admin costs don't scale.
Failing to clarify whether the rate applies to all invoices or just funded invoices. In selective invoice finance, some providers charge the service fee only on submitted invoices, others on your entire declared turnover.
Not reading the small print on additional charges. The quoted service charge may exclude bad debt protection premiums, credit report fees, or audit fees that add another 0.3-0.5% effective cost.

What to Do Next

Request a detailed fee schedule showing service charge, minimum monthly fee, discount charge, and any unbundled administration costs. Compare the total annual cost across three quotes using your actual invoice volumes.
Ask each provider to calculate the effective combined rate (service charge plus discount charge) based on your typical drawdown pattern, debtor payment terms, and monthly invoice volume. A worked example exposes hidden costs.
Check whether the service charge applies to all submitted invoices or only those you draw against, especially for selective facilities. If you only fund 60% of invoices, this distinction can halve your cost.
