The Funding Option UK Businesses Forget They Already Have

Here’s a question worth asking yourself honestly: when your business last ran short of cash, what did you do?

Most owners give the same answer. They called their bank. They dipped into an overdraft. They delayed paying a supplier, or quietly subsidised a large customer’s tardiness out of their own reserves, hoping the payment would arrive before the pressure became unbearable.

Very few thought: I have outstanding invoices. That is my working capital, sitting there already, waiting to be unlocked.

That gap, between what is available and what most business owners actually know about, is the subject of this article.

“Late payment forces SMEs to finance their customers. The question is whether they’re doing it for free.”

The scale of a problem nobody has solved

The numbers are stark:

• UK SMEs are collectively owed £70.4 billion in outstanding invoices at any given moment (Hiscox)
• The annual economic cost of late payment is £10.7 billion (Department for Business and Trade)
• Roughly 90% of UK businesses experienced late payment in the past year
• Sixteen businesses close every single day as a direct result

These are not new statistics. They are the chronic, structural condition of doing business in Britain.

Successive governments have launched voluntary codes, payment charters and regulatory consultations. The 2024 Fair Payment Code replaced the Prompt Payment Code amid much fanfare. Yet according to a 2025 survey by Coface, fewer than seven in ten small businesses even expect their cashflow to improve as a result.

Policy, in short, is not going to fix your cashflow. That’s something you have to do yourself, and it’s precisely where most SME owners are flying blind.

What comes to mind, and what doesn’t

Ask a business owner to name their short-term finance options and they’ll almost certainly reach for the familiar: bank overdraft, short-term loan, credit card, perhaps a director’s loan if things are tight. These are the products most people have grown up associating with business finance, the first call because they’re often the only call most owners have ever been told to make.

Merchant cash advances are increasingly part of the conversation too, particularly for businesses with steady card takings. They can be useful where repayment is linked to future sales. But that’s a different problem from a B2B business waiting for a known customer to pay an approved invoice. A merchant cash advance looks forward to tomorrow’s sales. Selective invoice finance looks back to work already completed and cash already earned.

That familiarity is expensive:

• 58% of SMEs have never explored any finance option beyond their main bank (Time Finance)
• Almost 40% have never even heard of specialist asset-based lending
• Awareness of invoice finance consistently lags behind loans, overdrafts and asset leasing, despite often being better suited to the cashflow problems SMEs actually face (British Business Bank)

The instinct to reach for a loan when cash is tight is understandable. But a loan creates new debt, requires monthly repayment regardless of whether customers have paid, and often demands a clean credit history or personal guarantee.

For a business whose problem is timing, not profitability, winning the work, doing the work, invoicing the work, then waiting forty-five days to be paid for it, a loan addresses the wrong end of the problem.

“The problem isn’t profitability. It’s timing. The money exists. It just hasn’t arrived yet.”

The oldest trade finance in the world

Invoice finance, or factoring as it was originally known, isn’t a modern fintech invention. Merchants in ancient Mesopotamia advanced funds against receivables. Tudor traders in England used agents to collect and advance against goods. The American textile industry was substantially financed this way in the eighteenth century. By most accounts, it’s the oldest form of commercial finance in existence.

It’s also, paradoxically, one of the least understood.

Part of the reason is historical stigma. For much of the twentieth century, factoring carried a faintly desperate reputation: if your invoices were being sold to a third party to raise cash, the assumption was that you were struggling. That perception was never entirely fair, but it was remarkably persistent, and it lingers even now in the instinctive reluctance of some business owners to consider invoice finance as a first-line tool rather than a last resort.

Part of the reason is also structural. Invoice finance has historically sat in specialist divisions within banks, away from the relationship manager who knew your business. It wasn’t on the menu when you walked in to talk about your overdraft, and it required a conversation most owners never had the opportunity to initiate.

The product has evolved significantly. The stigma, in too many cases, hasn’t.

How selective invoice finance actually works

The most important distinction to understand is between traditional whole-ledger invoice finance, where a business assigns all of its invoices to a funder as part of an ongoing facility, and selective invoice finance, which lets a business choose specific invoices to fund on an ad hoc basis, with no minimum commitment and no long-term contract.

The mechanics are straightforward:

• A business issues an invoice to a commercial customer on, say, sixty-day payment terms.
• Rather than waiting two months, the business presents that invoice to a selective invoice finance provider, who advances a large proportion of its value, typically 80 to 90%, usually immediately.
• When the customer pays at the end of the agreed credit period, the remaining balance is released to the business, minus the provider’s fees.

The advance is secured against the invoice itself, not against property or personal assets. Approval depends primarily on the creditworthiness of the debtor, the customer who owes the money, rather than the borrower’s credit history or years of audited accounts. The business retains control of its customer relationships, with no requirement to commit the entire sales ledger.

The arrangement can be disclosed, where the customer is informed the invoice has been assigned, or confidential, where the process is handled in a way that’s less visible to the end customer.

“Approval depends on the creditworthiness of your customer, not your own credit history.”

Who it suits, and who it doesn’t

Selective invoice finance works best for businesses that invoice other businesses on credit terms:

• Recruitment and staffing agencies, who must pay temporary workers weekly while waiting a month or more for client invoices to settle
• Construction subcontractors working on staged billing or delayed payment cycles
• Manufacturers and wholesalers who buy materials and build stock before the customer pays
• Transport and logistics businesses, whose fuel, wages and subcontractor costs fall due immediately while customers pay on extended terms
• Professional services firms, issuing high-value project invoices to reliable clients who can’t afford to let payment delays restrict day-to-day operations

It’s less well suited to businesses that sell to consumers rather than businesses, those with very small invoice values, or companies whose debtor book is dominated by customers with weak credit profiles. It’s not a substitute for permanent working capital infrastructure, and it should be assessed alongside other options rather than adopted reflexively.

The key question isn’t whether it exists, but whether it fits the specific shape of the cashflow problem at hand.

The benefits, and a candid word on the costs

The main advantages can be summarised without much embellishment:

• Fast — funding is typically available within 24 hours of a successful application
• Self-liquidating — the advance is repaid from invoice proceeds when the customer pays, not a separate monthly instalment
• Scales with turnover — a business growing quickly can access more funding without renegotiating a fixed facility
• Preserves other credit lines — using it doesn’t affect a bank overdraft or existing loan facility

For businesses with occasional pressure points, a large contract, a seasonal peak, a single slow-paying customer disrupting cashflow, the pay-as-you-go structure means you use it when you need it, and pay nothing when you don’t.

Costs vary by provider, but the typical structure involves a service charge (usually a small percentage of the invoice value) and a discount fee, charged against the advance while the invoice remains outstanding. On a sixty-day invoice, these combined costs are often more modest than people assume. The comparison that matters isn’t against a notional ‘cheapest possible finance’, but against the real cost of the alternative: delayed supplier payments, strained relationships, lost growth opportunities, or the ongoing drag of an overdraft facility permanently at its limit.

A few honest caveats: some debtor contracts contain clauses that restrict invoice assignment, so it’s worth checking terms before proceeding. If a customer pays significantly late, fees continue to accrue. And businesses with a very high volume of small invoices may find the administrative overhead less practical than a whole-ledger facility.

The awareness gap is the only real barrier

Of the 5.7 million SMEs operating in the UK, approximately 55,000 are estimated to use any form of invoice finance. That’s roughly 1%.

The UK Invoice Finance Benchmark Report 2025/6, an independent industry study, found that 84% of businesses not currently using the product said they’d benefit from having funds released from invoices immediately, yet most had simply never been told it was an option.

There’s no mystery here. The product works. The economics are often compelling. The legal and operational framework is well established. What’s missing, consistently and at scale, is basic awareness.

That matters because the alternative, waiting, borrowing against personal assets, using expensive short-term credit, or quietly absorbing the cost of late payment, has real consequences. Around 50,000 SMEs close every year in the UK due to cashflow problems – well over 100 per day. Not because they lacked orders. Not because their products or services failed. But because the money their customers owed them hadn’t arrived in time.

That’s a problem that, in many cases, has a straightforward solution. The most important step is simply knowing it exists.
