Invoice Finance: Everything you need to know

Key Takeaways

• Invoice finance lets a business borrow against unpaid invoices, advancing 70–95% of their value instead of waiting 30–90 days for customer payment.
• It splits into two main structures: factoring (funder manages collections) and discounting (business keeps control), as well as more selective, invoice-by-invoice options.
• Eligibility is based mainly on your sales ledger and customers' payment history, not just your own credit history, making it accessible to newer businesses too.

Invoice Finance: Everything You Need to Know

For many UK businesses, growth and cash flow don't move at the same speed. You might win a new contract, deliver the work, and raise the invoice, only to spend the next 30, 60 or even 90 days waiting for the money to actually land in your account. Invoice finance exists to close that gap, giving businesses a way to access cash that's already been earned rather than waiting on someone else's payment terms.

What is invoice finance?

Invoice finance is a form of short-term business funding that allows a company to borrow against the value of its unpaid invoices, rather than waiting for customers to settle them in full. A funder advances a percentage of the invoice value, typically somewhere between 70% and 95%, almost as soon as the invoice is raised. Once the customer eventually pays, the remaining balance is released to the business, minus the funder's fee.

Unlike a traditional loan, invoice finance isn't a fixed lump sum. Because it's tied to your sales ledger, the amount available to you naturally moves with your invoicing. Therefore, the more you sell, the more funding becomes available, without needing to renegotiate terms every time your business grows.

It's most commonly used by businesses that trade with other businesses (B2B) on credit terms, since this is where long payment cycles tend to cause the biggest cash flow strain.

The two main types of invoice finance 

There are two core ways invoice finance is typically structured: 

Invoice factoring: the funder takes over management of your sales ledger, including chasing payment from your customers directly. This is a more hands-off option for the business, with the funder effectively acting as your credit control department.

Invoice discounting: you remain in control of your own sales ledger and continue to manage customer relationships and collections yourself. Because your customers usually aren't aware a finance provider is involved, this is often referred to as confidential invoice discounting.

Beyond these two, facilities can also be arranged more selectively, allowing a business to fund specific invoices or customers rather than the whole ledger, which can suit companies that only occasionally need extra working capital.

How does invoice finance work in practice?

The process is fairly straightforward once a facility is in place. You deliver goods or services to a customer and raise an invoice as normal. Details of that invoice are then submitted to the funder, who advances an agreed percentage, usually within 24 to 48 hours. Depending on whether you've opted for factoring or discounting, either the funder or your own team will then be responsible for collecting payment from the customer. Once the invoice is settled, the funder releases the remaining balance to you, after deducting their service and discount charges.

Costs are typically made up of two elements: a service fee, which covers administration and (in the case of factoring) credit control, and a discount charge, which functions similarly to interest on the amount advanced. 

Who qualifies for invoice finance?

Eligibility for invoice finance tends to be assessed differently to a standard business loan. Rather than focusing purely on your company's own credit history, funders place significant weight on the strength of your sales ledger and the reliability of the customers who owe you money. Broadly, you're likely to qualify if:

• Your business invoices other businesses (B2B) on credit terms
• Invoices relate to completed work or delivered goods
• You operate as a limited company, LLP, PLC, partnership or sole trader
• Your customers have a reasonable track record of paying on time

Because the emphasis is placed on your customers' creditworthiness rather than solely your own, invoice finance can be more accessible to newer businesses or those with a limited trading history than some other forms of funding.

Why do businesses choose invoice finance?

Cash flow is the most obvious driver, but it's rarely the only one. Businesses turn to invoice finance when they want to take on larger contracts without waiting for existing invoices to clear, when they're growing faster than their customers are paying, or when they simply don't have property or other assets to offer as security for a loan. For businesses without significant assets, invoice finance offers a route to funding that's based on what they've already earned, not what they own.

It can also reduce the administrative burden of chasing payments, particularly with a factoring arrangement, freeing up time that would otherwise go into credit control.

Is invoice finance right for your business?

Invoice finance won't suit every business, companies that invoice consumers directly, or that raise very few, very large invoices to a small number of customers, may find other funding routes more appropriate. But for B2B businesses managing long payment terms, growing order books, or seasonal cash flow pressure, it can provide a flexible, scalable alternative to a fixed loan or overdraft.

Because facilities, fees and advance rates vary considerably between funders, it's worth comparing your options with a broker who has access to a wide panel of lenders, rather than approaching a single provider directly. This helps ensure the structure you end up with genuinely fits how your business operates.
