What is invoice finance? A UK SME guide

Invoice finance is one of the most under-explained finance products in the UK SME market. Owners often hear the word "factoring" and assume it means the same thing as a payday-style cash advance, or that the lender will hound their customers. Neither is true. Invoice finance is a working-capital facility designed specifically for businesses that sell to other businesses on credit terms, and it has a structure that is very different from a term loan or a merchant cash advance.

The core idea is simple. When you raise an invoice, the cash is locked up until the customer pays. For a £50k furniture importer selling into 60-day-payment retail chains, that lock-up can easily be £100,000 or more in working capital sitting in the ledger at any one time. Invoice finance lets you draw against that ledger as soon as you raise the invoice, rather than waiting for the payment to clear.

How invoice finance works

There are three moving parts: the advance, the service fee and the discount charge. The advance is the percentage of each invoice the lender will release upfront, typically 80 to 90 per cent. The service fee is a small percentage of turnover that covers the running cost of the facility. The discount charge is interest on the funds drawn, charged for the days the money is outstanding. When the customer pays the invoice, the lender clears its drawn balance, deducts its charges, and pays you the remainder.

Factoring vs invoice discounting

In factoring, the lender manages credit control: chasing payment, banking receipts and providing statements. Your customers know an invoice finance company is involved, although polite, professional providers like Bibby and Skipton Business Finance handle this discreetly. In invoice discounting, you keep control of collections and the arrangement is usually confidential. Discounting is generally only offered to more established businesses with proven credit control processes and stronger financials.

Selective and single-invoice finance

Some providers — Kriya and Skipton Business Finance among them — offer selective or single-invoice finance, where you pick specific invoices to fund rather than committing the whole ledger. This costs more per invoice but avoids the long contracts and minimum-fee commitments of a whole-turnover facility. It tends to suit businesses with one or two large invoices to a strong debtor rather than a steady book of trade.

Who invoice finance fits

• Established B2B businesses with at least six months of trading and a clean invoice process.
• Sectors with structurally long payment terms: construction subcontractors, recruitment, manufacturing, wholesale, transport and professional services.
• Businesses where customer concentration is reasonable — no single debtor accounts for more than 30 to 40 per cent of the ledger.
• Owners who want a facility that grows with sales, rather than a fixed-amount term loan.

Who it tends not to fit

• B2C businesses paid by card or cash at the point of sale — a merchant cash advance is usually the right shape.
• Pre-revenue or very early-stage trading where there is no invoice ledger yet.
• Businesses raising contra invoices, milestone billing or pay-when-paid sub-contracts, which factor lenders find very hard to underwrite.
• Companies with disputed invoices, credit notes or a history of bad debts in the ledger.

Typical costs in the UK market

Costs vary by ledger size, debtor quality and product. As a rule of thumb, expect a service fee in the 0.2 to 2.5 per cent of turnover range and a discount charge of 2 to 5 per cent over base on funds drawn. Smaller ledgers and weaker debtor books cost more. Confidential discounting is cheaper than factoring but harder to qualify for. Always ask for the all-in effective cost on your projected utilisation, not just the headline rate.

What lenders look at

1. Debtor quality: are your customers limited companies with clean credit?
2. Concentration: is the ledger spread across many customers or dependent on one?
3. Ageing: how much of the ledger is over 90 days old?
4. Dilution: how often are credit notes, contras or disputes raised?
5. Director profile: clean personal credit and no recent insolvency history.
6. Account history: 6 to 12 months of trading is normally the floor, although some providers will look at less for strong propositions.

Common blockers to be aware of

Most declines we see in this product fall into four buckets. First, ledger concentration: a recruitment firm with one large agency client accounting for 70 per cent of revenue will struggle to get a whole-turnover facility. Second, disputed or contra-billing: anything that gives the debtor a reason to refuse payment makes the invoice unfundable. Third, sector exclusions: stage payments and pay-when-paid arrangements in construction; non-recourse exporting outside scoped countries. Fourth, director adverse credit: a recent CCJ on a director's record can still kill a deal even where the company numbers look strong.

How to prepare your application

A clean application usually includes the last two years of filed accounts, the most recent management accounts, a current aged debtor and creditor report, a sample of customer contracts, and a director CV summary. If you can show that your top five customers are stable, well-rated UK limited companies with consistent payment behaviour, you remove most of the underwriting friction.

When to choose invoice finance over a loan

Invoice finance scales with sales — the facility size grows as your ledger grows — and the cost only applies to funds you draw. A term loan gives you a fixed lump sum with fixed repayments, which is simpler to budget for but less flexible. Owners who experience real cash-flow swings due to long payment terms tend to prefer invoice finance once they understand the structure. Owners with one-off purchase needs — a piece of equipment, a marketing push — tend to prefer a term product.
