Invoice finance is an umbrella term for any facility that advances cash against a business’s unpaid invoices – including invoice factoring, invoice discounting, selective invoice finance, and asset-based lending. In 2026, UK businesses use invoice finance to release an average of 80–90% of invoice value within 24 hours of raising a bill, without waiting the standard 30–90-day payment terms. Total UK invoice finance utilisation exceeded £20 billion in outstanding balances in 2025, according to UK Finance data.

Key Takeaways
  • Invoice finance advances 70-90% of invoice value - Access immediate cash flow while waiting for customer payments within 24 hours
  • Factoring costs 1.5-3% monthly vs discounting at 0.5-2% - Choose between full service factoring or confidential invoice discounting
  • SMEs with £100k+ annual turnover benefit most - Particularly effective for businesses with 30-90 day payment terms from customers
  • Bad debt protection available with factoring services - Providers manage collections & offer credit insurance, unlike basic invoice discounting
  • Setup fees range £500-2,000 plus ongoing charges - Compare providers as rates vary significantly based on turnover & industry risk

What Is Invoice Finance?

Invoice finance is a type of short-term business borrowing where a finance provider advances a percentage (typically 80–90%) of the value of your unpaid sales invoices. Instead of waiting 30, 60, or 90 days for your customers to pay, you access most of the cash immediately after raising the invoice. The remaining balance (minus fees) is released when your customer pays. Invoice finance is available as factoring (where the provider manages credit control) or discounting (where you retain credit control and the arrangement is confidential).

Invoice Finance vs Invoice Factoring vs Invoice Discounting

Invoice finance is the parent category. Invoice factoring is a type of invoice finance where the lender manages your sales ledger and credit control – your customers are aware of the arrangement. Invoice discounting is a type of invoice finance where you retain full credit control and the facility is confidential – your customers pay you directly, unaware of any third-party involvement. Both advance 80–90% of invoice value within 24 hours; the difference is who manages collections and whether customers know. Our Invoice Factoring UK has the latest figures. For a detailed comparison, see our Invoice Discounting UK.

How Does Invoice Finance Work?

The basic process: (1) You raise an invoice to your business customer on standard payment terms (30–90 days). (2) You submit the invoice to your invoice finance provider. (3) The provider advances 80–90% of the invoice value – typically within 24 hours. (4) Your customer pays the invoice when it falls due (either to the provider directly in factoring, or to a trust account in discounting). (5) The provider releases the remaining balance to you, minus their fees. The cycle repeats for each invoice or batch of invoices uploaded.

Invoice Finance Rates and Fees UK 2026

Invoice finance has two cost components: (1) a discount charge – equivalent to interest on the amount advanced, typically 1.75–4.5% above the Bank of England base rate (currently 3.75%), meaning an effective annual rate of approximately 5.5–8.25% on drawn balances; and (2) a service charge – a percentage of turnover (0.1–3% for discounting; 0.5–3% for factoring) covering administration and, in factoring, credit control. Selective invoice finance charges a flat fee per invoice (1–3% of invoice value) with no monthly commitment. Always compare total annual cost, not the headline advance rate. Our Best Invoice Finance Companies UK 2026 breaks this down further.

Who Is Invoice Finance For?

Invoice finance is designed for B2B businesses that issue invoices on standard payment terms and experience cash flow gaps between raising invoices and receiving payment. It is particularly common in: recruitment (weekly payroll funded by 30-day invoices), construction (stage payment gaps), logistics and transport (fuel and driver costs ahead of 60-day payment terms), manufacturing (raw material costs vs 90-day buyer terms), and professional services. It is not suitable for B2C businesses, cash-on-delivery businesses, or businesses that do not invoice other businesses on deferred payment terms.

Pros and Cons

What we like
Unlocks up to 90% of invoice value within 24 hours – faster than waiting 30-90 day payment terms
Flexible: fund your entire ledger or select individual invoices
Grows with your business – facility size increases automatically as turnover rises
Bad debt protection available as add-on (non-recourse factoring)
No fixed assets required as security – invoices themselves are the collateral
Watch out for
Ongoing cost: two-fee structure (finance charge + service charge) adds up over time
Factoring: your customers know a third party is involved (may affect relationships)
Not suitable for businesses that invoice consumers (B2C invoices are rarely accepted)
Minimum turnover requirements exclude very small businesses from institutional providers
Contract terms: most whole-ledger facilities require 12-24 month minimum commitment

FAQs

What is invoice finance?

Invoice finance is an umbrella term for borrowing against your unpaid invoices. A lender advances 70-90% of the invoice value upfront, then you receive the remainder (minus fees) when your customer pays. The two main types are factoring and invoice discounting.

How much does invoice finance cost in the UK?

Costs typically include a service fee (0.2-0.5% of turnover for discounting, 0.5-3% for factoring) plus a discount rate (1-3% above base rate on the amount advanced). Total cost depends on your turnover, number of debtors, and sector risk profile.

Is invoice finance suitable for small businesses?

Yes. Many providers now offer invoice finance to businesses with annual turnovers from £50,000. Selective (spot) invoice finance lets you finance individual invoices without committing your entire ledger, which suits smaller businesses with occasional cash flow gaps.

Will my customers know I am using invoice finance?

It depends on the type. With confidential invoice discounting, your customers are not informed – you collect payments as normal. With factoring, the finance provider contacts your customers directly to collect. If confidentiality matters, choose invoice discounting.

How quickly can I access funds with invoice finance?

Most providers release funds within 24 hours of receiving an approved invoice. Initial setup takes 1-2 weeks for due diligence, but once the facility is live, subsequent drawdowns are typically same-day or next-day.
