What is Invoice Finance?

Invoice finance is a funding solution that allows businesses to release cash tied up in unpaid invoices. Rather than waiting for business customers to pay, a percentage of the invoice value is made available almost immediately.

This helps businesses:

  • Improve cash flow.
  • Fund growth.
  • Pay suppliers on time.
  • Invest in staff and equipment.
  • Reduce pressure caused by slow-paying customers.

Unlike many traditional funding options, invoice finance grows alongside your business because funding availability is linked to your invoicing activity.

More often, they apply because they are growing.

Common reasons include:

Long Payment Terms

Seasonal Demand

Cash flow can fluctuate dramatically throughout the year.

Replacing Expensive Borrowing

Invoice finance can often be a more flexible and cheaper alternative to traditional borrowing.
