What Is Invoice Finance?

Invoice finance is a flexible funding solution that allows businesses to release cash tied up in unpaid invoices. Instead of waiting 30, 60, or even 90 days for customers to pay, businesses can access up to 95% (or even 100% minus fees in some cases) of their invoice value upfront.

See our detailed Guide To Invoice Finance to find out how it works and see example pricing.

How Much Cash Can I Get From Invoice Finance?

The amount of funding you can access depends on several factors:

  • The total value of your unpaid invoices – The more outstanding invoices you have, the more cash you can release.
  • The advance rate – Typically 70% to 95% of invoice values.
  • Your industry and customer payment history – Some sectors qualify for higher advance rates.
  • Your finance provider’s terms – Different funders have different risk appetites and advance rates.
