What Is Invoice Finance?

A signed contract and a raised invoice are not the same as cash in the bank. For businesses selling on 30, 60, or 90-day payment terms, the gap between delivering work and getting paid for it is one of the most reliable ways a healthy, profitable business runs into trouble.

Invoice finance is built specifically for that timing problem. A lender advances you a percentage of your outstanding invoices, typically 80 to 90%, without waiting for your customers to settle. When they do pay, the remaining balance is released to you minus the lender's fees. The facility revolves automatically with your invoicing activity, so your access to cash grows as your business does.

The product is well established across UK SMEs. It is particularly common in sectors where long payment terms are simply how the industry operates: recruitment, professional services, construction, manufacturing, wholesale distribution, and transport. In these businesses, it is normal to have six figures of cash tied up in unpaid invoices at any given moment, and invoice finance is the standard tool for managing it.

How invoice finance works

The mechanics are consistent across all types of invoice finance, even though the product names vary. Once you have a facility in place, the process runs like this:

1. You raise an invoice to a business customer.

2. You notify your lender. In most modern setups this happens automatically via an integration with your accounting software.

3. The lender advances you up to 85 to 90% of the invoice value, usually within 24 hours.

4. Your customer pays the invoice on their normal payment terms.

5. The lender releases the remaining balance to you, minus their fees.

The facility is revolving. As invoices are raised and settled, your available funding moves with your ledger. If your turnover grows, your access to working capital grows with it, without a new loan application each time you win a larger contract.

This is the fundamental difference from a term loan. A loan gives you a fixed sum. Invoice finance gives you a funding line tied directly to your sales activity. Many businesses use both: a term loan for a specific capital purchase, invoice finance for day-to-day working capital. They solve different problems and are not mutually exclusive.

The two main types of invoice finance

The product comes in two main forms: invoice factoring and invoice discounting. Both advance cash against unpaid invoices. The difference is who manages credit control and the relationship with your customers.

Invoice factoring

With factoring, the lender takes over your credit control function. They chase customers for payment, manage aged debt, and collect what is owed. Your customer knows they are dealing with a finance provider rather than you directly.

This suits businesses that want the administrative overhead of credit management taken off their hands. Factoring is also more accessible. Eligibility thresholds are lower, and newer businesses with less trading history are more likely to qualify. The trade-off is cost and visibility. Fees are higher than for discounting because the lender is doing more work, and the arrangement is not confidential.

Invoice discounting

With discounting, you continue managing your own sales ledger and chasing customers for payment. The arrangement is typically confidential. Your customer pays you on their normal terms and has no reason to know a lender is involved.

Discounting usually requires a minimum annual turnover of around £500,000 and a demonstrable credit control function within the business. Fees are lower than factoring because the lender's workload is smaller. If you already have a finance function that handles collections competently, discounting gives you the cash flow benefit without handing over your customer relationships.

For most growing businesses, factoring is the practical entry point. As the business scales and the finance function matures, discounting often makes more sense on both cost and control grounds. Our guide to invoice discounting vs factoring covers the comparison in detail.

Other forms of invoice finance

Beyond factoring and discounting, there are a few variants worth knowing about.

Selective invoice finance, also called spot factoring or single invoice finance, lets you fund individual invoices rather than committing your whole sales ledger. You choose which invoices to advance against and when. The cost per invoice is higher than a whole-ledger facility, but the flexibility suits businesses that only occasionally need to release cash rather than those with a permanent working capital gap. Our guide to selective invoice finance explains when it makes sense.

Recourse vs non-recourse facilities is a distinction that applies to both factoring and discounting. With recourse invoice finance, if your customer does not pay, you are liable to repay the advance. Non-recourse transfers that credit risk to the lender at a higher cost. If you have significant exposure to a small number of large clients, non-recourse protection is worth examining before you sign.

Recruitment invoice finance is a specialist variant built for the specific cash flow dynamics of staffing agencies, where payroll has to be met weekly while clients pay on 30 to 90-day terms. General-purpose facilities do not always handle the pay-before-you-get-paid cycle well; specialist providers build products around it.

Who invoice finance is for

Invoice finance works for businesses that:

• Sell on credit terms to other businesses (B2B only)

• Invoice on payment terms of 30 days or longer

• Have a turnover of at least £50,000 to £100,000 a year (thresholds vary by lender and product type)

• Have a debtor book of unpaid invoices to advance against

Take a manufacturer supplying a national retailer on 60-day payment terms. The goods have shipped, the invoices are raised, the retailer will pay. But the cash is locked up for two months, and the next production run needs funding now. Invoice finance releases that locked cash the next day. The retailer never knows it is involved.

It does not work for businesses that sell direct to consumers, take payment on delivery, or collect cash upfront at point of sale. Retail, hospitality, and most consumer services do not fit the model because there is no debtor book to advance against.

The sectors where invoice finance is most embedded are those where slow payment is structural rather than exceptional: construction contractors waiting on retention payments, manufacturers supplying supermarkets or retailers on 60-day terms, logistics companies billing freight clients monthly, and professional services firms on milestone payment schedules. In each of these, the cash flow gap is predictable and recurring, which makes a revolving facility more practical than a series of one-off loans.

What invoice finance costs

Invoice finance is priced across two main components, and understanding both is important before comparing providers.

The discount rate is the interest charge on the advance. It works like an overdraft. You pay interest for each day the advance is outstanding. Rates are typically quoted as the Bank of England base rate plus a margin, and the all-in annualised rate generally falls between 1.5% and 3.5%, depending on your turnover, sector, and the creditworthiness of your customer base.

The service fee covers the lender's administration. It is calculated as a percentage of your total monthly invoiced turnover. For a discounting facility, expect 0.2% to 0.5%. For factoring, where the lender is also managing your collections, expect 0.5% to 2.5%.

Watch for ancillary charges on top of these two headline costs: audit fees (lenders periodically verify invoices and the underlying debts), minimum monthly fees, and early termination penalties. These vary significantly between providers and can add materially to the total cost if you do not factor them in when comparing quotes.

As a rough benchmark, for a business with £500,000 annual turnover and an average debtor balance of £50,000, the all-in annual cost of a discounting facility typically falls between £3,000 and £7,000. Your actual figure depends on your lender, sector, advance rate, and how much of the facility you use each month.

Is invoice finance the right solution?

Invoice finance works well when cash flow timing is the problem, not cash flow volume. If you have a solid order book, your customers pay reliably, but the wait between raising an invoice and receiving payment is limiting what you can take on next, this is the product for that situation. It does not fix a bad business. It fixes a timing problem in a good one.

It is not a rescue product. Lenders assess the creditworthiness of your customers as part of the underwriting, but they also look at your own financials. A pattern of persistent bad debt, customers who routinely pay late or dispute invoices, or a business running consistent losses makes approval harder and terms worse. Invoice finance works best when the underlying business is healthy and the problem is purely timing.

The question worth asking before applying is whether this is a structural problem or a temporary one. If you will always have a working capital gap because of the nature of your payment terms, a revolving invoice finance facility is a good long-term fit. If the pressure is temporary, a short-term loan or a business overdraft may be a lower-cost option that does not require committing your whole ledger.

For most UK B2B businesses invoicing on 30-day terms or longer, with turnover above £100,000, invoice finance is worth getting a quote for. The application process is quicker than most business owners expect, and the all-in cost is often lower than the equivalent business loan.

Frequently asked questions

What is the difference between invoice finance and factoring?

Invoice factoring is one type of invoice finance. The broader category also includes invoice discounting and selective invoice finance. With factoring, the lender takes over your credit control and chases customers for payment. With discounting, you manage that process yourself and the arrangement stays confidential. Both advance cash against unpaid invoices.

How quickly can I access funds through invoice finance?

Most lenders advance funds within 24 to 48 hours of an invoice being raised. Once your facility is live, the process runs largely automatically via your accounting software integration. The advance typically arrives the next working day once the lender receives the invoice notification.

Can a startup use invoice finance?

Yes, in some cases. Factoring providers assess your customers' creditworthiness more heavily than your own trading history, so newer businesses can qualify if they are invoicing creditworthy clients. Invoice discounting is harder to access for businesses with less than 12 months' trading history or below the minimum turnover threshold, which most lenders set at around £500,000.

Is invoice finance regulated in the UK?

Invoice finance providers are not required to be FCA-regulated in the same way as consumer credit lenders, because the product is extended to businesses rather than consumers. Many providers are members of UK Finance, the industry trade body, and operate under its voluntary codes of practice covering transparency and conduct.

What happens if my customer does not pay?

This depends on whether your facility is recourse or non-recourse. With recourse invoice finance, if the customer fails to pay, you are liable to repay the advance to the lender. Non-recourse invoice finance transfers that credit risk to the lender at a higher cost. If you have significant turnover concentration in a small number of clients, non-recourse protection is worth pricing up before you commit to a facility structure.
