What Is Invoice Finance? A Complete Guide for UK Businesses

Late-paying customers are one of the biggest cash flow challenges facing UK businesses in 2026. When money is tied up in unpaid invoices, growth can stall, suppliers go unpaid, and payroll gets tight. Invoice finance is one option designed to help with this problem.

What Is Invoice Finance?

Invoice finance is a funding arrangement where a lender advances you a percentage of the value of your unpaid invoices, often within 24 hours of you raising them (subject to the provider and approval). Instead of waiting 30, 60 or even 90 days for a customer to pay, you can access much of the cash sooner.

Providers will typically advance up to around 80–90% of the invoice value upfront. The remaining balance, minus fees, is released once your customer settles the invoice.

How Invoice Finance Works

The process is broadly:

You raise an invoice to your business customer. The lender advances a percentage of that invoice value to you. Your customer pays the invoice within the agreed terms. The lender releases the remaining balance to you, minus their fee.

Main Types of Invoice Finance

The two most common facilities are invoice factoring, where the lender manages your sales ledger and collects payment from your customers directly, and invoice discounting, where you retain control of your own credit control and the arrangement can be kept confidential from your customers. Other options include selective invoice finance (financing individual invoices) and asset-based lending for larger, more complex requirements.

Points to Consider

Invoice finance is not free, and it is not right for every business. Consider that fees and interest apply and reduce the amount you ultimately receive; with a recourse facility you may have to repay the advance if your customer does not pay; facilities can involve minimum terms or notice periods; and it works best for B2B businesses invoicing creditworthy customers. It is most commonly used across recruitment, construction, manufacturing, logistics and wholesale, where long payment terms are common.

Final Thoughts

For businesses that invoice other businesses and wait weeks to get paid, invoice finance can help improve working capital — provided the costs and terms suit your circumstances. Understanding how it works is the first step to deciding whether it is right for you.

Important information

Invoice finance provided to limited companies and LLPs is a commercial, business-to-business product and is generally not regulated by the FCA, and typically falls outside the Consumer Credit Act 1974. Facilities taken by sole traders or small partnerships may carry different protections — check your agreement.
