What is invoice finance and how can it help your cash flow?

Business Finance Guide

By Caply  ·  May 2026  ·  5 min read

Waiting weeks or months for a client to pay an invoice is one of the most common cash flow problems UK businesses face. You have done the work, raised the invoice, and now you are sitting on money that is technically yours but completely out of reach.

Invoice finance is designed to solve exactly that problem. This guide explains how it works, the two main types, who it suits, and whether it could be the right fit for your business.

What Is Invoice Finance?

Invoice finance is a way of unlocking the cash tied up in your unpaid invoices before your clients actually pay them. Rather than waiting 30, 60, or 90 days for payment, a lender advances you the majority of the invoice value upfront, typically between 80% and 90%. When your client pays, you receive the remaining balance minus the lender's fee.

It is not a loan in the traditional sense. You are not borrowing against future revenue. You are simply accessing money that is already owed to you, just sooner than your payment terms allow.

If you raise a £50,000 invoice with 60-day payment terms, invoice finance could put £40,000 to £45,000 in your account within 24 hours rather than two months down the line.

The Two Main Types

Invoice finance comes in two forms. Understanding the difference will help you choose the right one for your business.

Option 01

Invoice Factoring

The lender takes over the collection of your invoices directly, chasing payment from your clients on your behalf. Your clients will be aware that a third party is managing collections. Best suited to businesses that want to hand off credit control entirely.

Option 02

Invoice Discounting

You retain full control of your sales ledger and continue chasing payment from clients yourself. The arrangement remains confidential so your clients never know a lender is involved. Better suited to businesses with established credit control processes.

How It Compares to Other Finance Options

Feature Invoice Finance Business Loan Overdraft
Based on Your unpaid invoices Business financials Bank relationship
Funding grows with Your sales ledger Fixed amount agreed Fixed limit set by bank
Repayment When client pays invoice Fixed monthly payments On demand by bank
Security needed Invoices act as security Sometimes required Sometimes required
Speed to fund 24 to 48 hours Days to weeks Slow to arrange

Who Is Invoice Finance Best Suited For?

Invoice finance works best for B2B businesses that invoice other businesses or organisations on credit terms. It is less relevant for businesses that are paid immediately at point of sale.

It is particularly well suited to businesses in these situations:

Situation 01

Rapid Growth

When you are winning new contracts faster than your cash flow can keep up, invoice finance scales with your sales ledger automatically.

Situation 02

Long Payment Terms

Working with large clients or public sector organisations often means 60 to 90 day payment terms. Invoice finance bridges that gap.

Situation 03

Seasonal Businesses

If your revenue is lumpy or seasonal, unlocking invoice value gives you working capital when you need it rather than when your clients decide to pay.

Situation 04

Funding a Large Contract

Winning a big contract is great. Funding the staffing and materials upfront before payment arrives is harder. Invoice finance solves that problem.

The Pros and Cons

Advantages
  • Access cash tied up in invoices within 24 to 48 hours
  • Funding grows automatically as your sales ledger grows
  • No fixed monthly repayments to manage
  • Invoices act as security so no separate assets required
  • Can be arranged confidentially with invoice discounting
  • Reduces the risk of bad debt with some facilities
Limitations
  • Only available to businesses that invoice other businesses
  • Not suitable if clients pay immediately at point of sale
  • Fees can accumulate if clients pay slowly
  • Factoring means clients know a third party is involved
  • Some lenders require a minimum level of monthly invoicing

What You Need to Apply

Invoice finance applications are generally straightforward. Lenders want to understand the quality and volume of your sales ledger rather than just your credit history.

1

A list of your current outstanding invoices. Lenders will want to see who owes you money, for how much, and how overdue the invoices are.

2

3 months of business bank statements. These help lenders understand your overall trading pattern and cash flow position.

3

Details of your main customers. Lenders assess the creditworthiness of the businesses paying your invoices, so knowing who your clients are helps them make a faster decision.

4

Your most recent accounts if available. Not always essential but can help secure better rates and higher advance percentages.

Is Invoice Finance the Right Option for You?

If your business invoices other businesses on credit terms and cash flow is being squeezed by slow-paying clients, invoice finance is one of the most effective tools available. It does not add debt to your balance sheet in the traditional sense and it scales naturally with your business.
