Invoice Finance and Factoring Explained
If your business invoices customers and waits 30, 60, or even 90 days to get paid, invoice finance turns those unpaid invoices into cash you can use today. Here’s how it actually works, what factoring and invoice discounting mean in practice, and what it really costs.
What invoice finance actually is
Invoice finance is borrowing secured against your unpaid sales invoices rather than against property or other assets. Instead of waiting for a customer to pay in full, a provider advances you a large percentage of the invoice value almost immediately — often within 24 hours of raising it — with the remainder (minus fees) paid to you once the customer settles.
It’s a facility rather than a one-off loan: as new invoices are raised, they become available to draw against, so the funding available grows in line with your sales. This is fundamentally different from a term loan, where you borrow a fixed amount up front and the facility doesn’t grow with your business.
Factoring vs invoice discounting
The two main forms of invoice finance work quite differently in practice, even though both advance cash against unpaid invoices:
The finance provider takes over credit control and collects payment directly from your customers. This is “disclosed” — your customers know a third party is involved in collecting the debt. It suits businesses without their own credit control function, but costs more because the provider is doing that work for you.
You keep control of credit control and collect payment from customers as normal — the finance simply sits in the background. This is usually “confidential”, meaning customers aren’t aware the facility exists. It’s cheaper than factoring but requires you to have a reasonably robust internal process for chasing payment.
Invoice discounting is generally only offered to businesses with a certain level of turnover and financial reporting maturity, since the provider is relying on your own credit control being effective. Smaller or younger businesses are more commonly offered factoring instead.
How the costs work
Invoice finance pricing has three separate components, which can make it harder to compare than a simple interest rate:
| Cost element | Typical range | What it covers |
|---|---|---|
| Advance rate | 75% – 95% of invoice value | How much you receive upfront; the rest follows once the customer pays, minus fees |
| Service fee | 0.5% – 3% (factoring), 0.5% – 1.5% (discounting) | The provider’s administration charge, usually a percentage of turnover |
| Discount charge | 2% – 6% above the Bank of England base rate | The interest cost on the amount advanced, similar in structure to an overdraft |
With the base rate currently at 3.75%, a business paying a 3% margin would see an effective discount charge of around 6.75% on the funds drawn — though pricing is genuinely bespoke, and both the margin and the service fee depend heavily on your turnover, sector, customer base, and how factoring or discounting is quoted by that particular provider.
Recourse vs non-recourse
A further distinction affects who carries the risk if a customer simply doesn’t pay:
- Recourse factoring: if a customer fails to pay, you’re responsible for repaying the advance to the provider. This is the more common and cheaper option.
- Non-recourse factoring: the provider absorbs the loss if a customer becomes insolvent or fails to pay (within agreed limits), effectively bundling in a form of bad debt protection. It costs more, reflecting that additional risk the provider is taking on.
Non-recourse facilities typically only cover non-payment due to genuine insolvency, not simply a slow or disputed payment, so it’s worth reading exactly what’s covered rather than assuming blanket protection.
Who it suits
Invoice finance tends to suit businesses that invoice other businesses (B2B) with standard payment terms, rather than consumer-facing businesses that are paid immediately. It’s a particularly strong fit where:
- Payment terms are long, tying up working capital for 30, 60, or 90 days after delivering the work.
- Sales are growing, since the facility scales automatically rather than needing a fresh loan application each time funding needs increase.
- Cash flow is the constraint, not profitability — a genuinely profitable business can still struggle for cash if customers are slow to pay.
- Traditional lending is difficult to access, since invoice finance is secured against the invoices themselves rather than relying purely on trading history or credit score.
It suits it less well where customer numbers are very small and concentrated (a handful of large customers can make a facility feel precarious) or where invoice values and payment terms are already short and predictable.
Pros and cons
Fast access to cash tied up in invoices; funding grows automatically with sales; factoring can outsource credit control entirely; often more accessible than a term loan for younger or lower-credit businesses.
Can be more expensive than it first appears once all fees are included; factoring means customers know a third party is involved; reliance on ongoing sales volume means income disruption directly affects available funding; exit and minimum volume terms can lock you in.
Choosing a provider
- Get the full fee schedule in writing, not just the headline advance rate and service fee.
- Ask specifically about minimum volume commitments, since some facilities charge fees based on expected turnover even if actual invoicing falls short.
- Check the contract length and exit terms, including notice periods and any penalty for leaving early.
- For factoring, ask how credit control is actually handled, since the provider’s approach to chasing your customers reflects on your business relationships.
- Compare more than one provider, ideally through a broker who works across several lenders, since pricing varies significantly by sector and customer profile.
Common mistakes
Missing service fees, discount charges, and additional costs that materially affect the total price.
Paying for credit control support the business doesn’t actually need.
Assuming broader bad debt protection than the policy actually provides.
Which can make leaving an unsuitable facility more costly than expected.
Which can make a facility fragile if one of them delays payment or becomes insolvent.
