A Guide to Invoice Finance

For businesses that sell to other businesses, the hardest part of trading often isn’t winning the work, it’s waiting to be paid for it. Payment terms of 30, 60 or even 90 days mean that a busy month can leave a business cash poor precisely when it’s most successful, with thousands of pounds earned but locked away in unpaid invoices.

Invoice finance exists to unlock that money. In this guide, we’ll explain how it works, the difference between factoring and invoice discounting, what it costs, and how to decide whether it’s the right form of business finance for you.

What Is Invoice Finance?

Invoice finance is a facility that advances you most of the value of your unpaid invoices as soon as you issue them, rather than making you wait for the customer to pay. Typically a provider advances around 80% to 90% of an invoice’s value, often within 24 hours of it being raised. When your customer eventually pays, you receive the remainder, minus the provider’s fees.

The effect is that your cashflow tracks your sales instead of your customers’ payment habits. The British Business Bank describes it as a way for businesses trading on credit terms to strengthen cashflow without waiting out their payment cycle, and that’s exactly the situation it’s designed for.

Because the borrowing is tied to invoices, the facility grows with your business automatically: more sales means more invoices, which means more available funding, with no need to renegotiate a limit.

Factoring vs Invoice Discounting

Invoice finance comes in two main forms, and the difference matters more than any other choice you’ll make about it.

Invoice Factoring

With factoring, the provider advances the money and also takes over collecting payment from your customers. Their team chases the invoices, and your customers will generally know a finance provider is involved because payments go to the provider.

Factoring suits businesses that would rather hand off credit control entirely, effectively getting an outsourced collections function bundled with the funding. The trade-off is visibility: your customers see the provider in the process, and you hand over part of the customer relationship.

Invoice Discounting

With invoice discounting, you keep collecting payments from customers exactly as you do now, and the finance stays confidential. Customers pay into an account as normal and need never know a facility exists.

Discounting suits established businesses with solid credit control processes of their own. Because the provider relies on your collections rather than their own, discounting is usually offered to businesses with a track record, decent systems and a well spread customer base, and it’s typically cheaper than factoring since the provider isn’t running your credit control.

What Does Invoice Finance Cost?

Pricing usually has two parts. A service fee, typically a small percentage of turnover put through the facility, covers running the facility (and, with factoring, the collections work). A discount fee, essentially interest, is charged on the funds you’ve drawn for the time you’ve drawn them.

Between the two, invoice finance generally costs more than a straightforward term loan for the same amount, and in return you get funding that arrives faster, flexes with sales and requires no fixed asset security. Whether that trade is worth it depends on how central the payment gap is to your cashflow problem. As with any facility, compare total costs across providers and check for minimum fees, contract lengths and notice periods; our guide to business loan interest rates and fees covers the comparison principles.

One term to understand before signing: recourse. Most facilities are with recourse, meaning if your customer never pays, the advance on that invoice is clawed back from you. Some providers offer bad debt protection (non-recourse) for an extra fee, which can be worthwhile if your sales are concentrated in a few large customers.

Is Invoice Finance Right for Your Business?

Invoice finance fits a specific shape of business very well:

  • You sell to other businesses on credit terms, since consumer sales paid immediately generate no invoices to finance.

  • Payment terms or slow payers are the main source of your cashflow pressure.

  • Your customers are reasonably creditworthy, because the strength of your debtor book is what providers assess most.

  • Sales are growing, so you want funding that scales without repeated renegotiation.

It’s less suitable when your cashflow pressure has other causes, when margins are too thin to absorb the fees, or when you invoice only a handful of customers whose disputes or delays could destabilise the facility. If late payment is an occasional irritation rather than a structural problem, remember you’re also entitled to charge statutory interest on late commercial payments, and a tighter credit control process may solve more than a facility would.

If the need is a defined lump sum rather than an ongoing gap, a working capital loan is simpler, and if the need ebbs and flows, compare a revolving credit facility, which offers flexible drawdown without touching your invoicing at all.

Questions to Ask a Provider

  • What advance rate applies to our invoices, and are any customers or invoice types excluded?

  • What are the service fee, discount fee and any minimum monthly fees?

  • Is the facility with recourse, and what does bad debt protection cost?

  • For discounting, is the facility fully confidential?

  • What is the contract length, and what notice is needed to exit?

Final Thoughts

Invoice finance turns your sales ledger into a source of funding, which makes it one of the most natural forms of finance for established businesses trading on credit terms. Factoring adds collections muscle for businesses that want it; discounting adds quiet flexibility for businesses that don’t. Cost more than a loan, flexibility more than a loan: that’s the trade. If unpaid invoices are where your cash is hiding, it’s a trade well worth pricing up alongside conventional borrowing.
