After twenty-odd years working with businesses on finance, you start noticing something peculiar.
When people talk about cashflow, they focus on the wrong question.
The conversation usually goes: “How do I improve cashflow?” or “What funding do I need?”
Rarely does anyone ask: “Why am I funding someone else’s business?”
Because that’s what’s happening. UK small businesses are currently owed £70.4 billion in late payments 
. In just six months to December 2025, £8.75 billion of supplier invoices were paid late by large UK companies . Over £5 billion of that related to invoices where there was no dispute.
Not administrative oversights. Not processing delays. Policy.
When Your Customer Becomes Your Lender: The UK Cashflow Crisis
You deliver the work. You send the invoice. The clock starts ticking.
But instead of payment arriving in 30 days, it arrives in 60. Or 90. Sometimes longer.
During that period, you’ve already paid your suppliers. Your staff. Your rent. Your VAT bill doesn’t wait for your customers to pay you.
So you bridge the gap. From reserves, from your overdraft, from somewhere.
You’ve just provided an interest-free loan to your customer. Except you didn’t choose to be a lender – and you’re probably paying interest yourself to cover the gap.
The madness is that many of the businesses doing this have strong margins and solid order books. They’re profitable on paper. They’re just permanently skint in practice.
Profit doesn’t pay wages. Cash does.
The Scale of Late Payment Problems in UK Business
29 companies take 100 days or more on average to pay .
122 companies pay at least 70% of their invoices late.
That’s not inefficiency. That’s not accident.
Some household names appear repeatedly on late payer watchlists. Travis Perkins extended supplier terms from 30 to 60 days and paid over £791 million in undisputed invoices late. Baxi Heating reportedly paid 96% of invoices late. Red Bull paid 85% late.
These aren’t struggling businesses. They’re choosing to use suppliers as a source of working capital.
Which is a perfectly rational decision – if you’re the one receiving the extended terms. Less rational if you’re the one providing them.
The Real Cost of Late Payments for SMEs
Around 14,000 UK businesses close each year due to late payment . That’s 38 businesses every day.
Not because they weren’t profitable. Not because their business model didn’t work. Because the cash wasn’t there when the bills came due.
If your margins are 5% and you write off a £10,000 bad debt, you need £200,000 in additional sales just to stand still. Most businesses don’t calculate that. They just absorb it and keep going.
Until they can’t.
The businesses I see getting into trouble aren’t typically the ones with bad ideas or lazy management. They’re the ones who’ve been too accommodating for too long. 60-day terms become 90. 90 becomes 120. One late payer becomes normal. Then three. Then it’s just how things work.
Invoice Finance: Converting Late Payments Into Working Capital
You can’t force a large customer to pay faster. But you can stop carrying the full cost of their payment behaviour.
Invoice finance converts your unpaid invoices into working capital – typically within 24 hours of raising the invoice. You get 80-90% of the invoice value immediately. The remaining balance (minus fees) comes through when your customer eventually pays.
It’s not a loan. You’re releasing capital that’s already yours – just locked in credit terms.
The businesses that use it well don’t see it as emergency funding. They see it as a structural solution to a structural problem. If your customers are going to treat you as a lender, you need a way to convert those receivables back into usable cash without waiting three months.
How Confidential Invoice Discounting Works
Confidential invoice discounting works particularly well for established businesses. Your customers don’t know you’re using it. The relationship doesn’t change. But your cashflow does.
According to UK Finance, invoice finance and asset-based lending provides over £20 billion in funding at any time, totalling £125 billion annually .
It won’t solve every problem. If your margins are too tight or your customers genuinely can’t pay, finance just delays the inevitable. But if the issue is timing rather than solvency – if you’re waiting on good invoices from solvent customers – it removes the gap between delivery and payment.
Business Cashflow Solutions: The Question Worth Asking
Most businesses I speak with have never really questioned the idea that they should fund their customers’ operations for 60, 90, or 120 days.
It’s just what you do. The customer’s bigger. They set the terms. You accept them.
But there’s a difference between accepting payment terms and accepting that you’ll carry the full financial strain of those terms.
If a customer insists on 90-day terms, fine. That’s their choice. Whether you finance that period through your own cashflow or through a facility that releases the value immediately – that’s yours.
The £70 billion question isn’t whether late payment will stop. It probably won’t, not completely.
It’s whether you’re going to keep funding it from your own reserves – or whether you’re going to structure your business so those payment terms don’t determine whether you can make payroll, take on new work, or invest in growth.
None of this matters if your customers pay on time.
But if you’re chasing 14 late payments a year and spending the equivalent of 331 days waiting , the real question is whether you can afford to keep doing it.
