How UK small businesses are using credit cards to extend cashflow

12 March 2026 · QuidClever

The cashflow gap is real

If you run a UK small business, you know the drill. Suppliers want paying in 14-30 days. Your customers take 30-60 days to pay you. That gap can make or break your business.

According to recent research, late payments cost UK SMEs an average of £22,000 per year. And 50,000 businesses close every year directly because of cashflow problems — not because they're unprofitable, but because the timing of money in vs money out just doesn't work.

The credit card float trick

Here's what smart business owners are doing: they're routing their supplier payments through a business credit card, even when those suppliers only accept bank transfers.

Using a bill payment service, you can put virtually any invoice on your credit card. Rent, contractors, stock, even HMRC. The supplier gets a bank transfer (so they don't need to accept cards), and you get 30-45 extra days before the money actually leaves your account.

That's 30-45 days of free float. No loan application. No overdraft fees. No equity dilution.

The maths

Say you're a small e-commerce business paying £10,000/month in supplier invoices. Currently, that money leaves your account on day 1.

With credit card bill payments:

  • Day 1: Invoice uploaded, paid via credit card
  • Day 30-45: Credit card bill due
  • Net effect: £10,000 stays in your account for an extra 30-45 days every single month

That's effectively a £10,000-£15,000 interest-free working capital facility. Every month. Automatically.

Yes, there's a 1.5-2.5% fee per transaction. But compare that to an overdraft (15-20% APR), invoice finance (5-15%), or a business loan (8-15% APR). Credit card float is dramatically cheaper.

Stacking rewards on top

The beautiful part? You're also earning credit card rewards on this spend. With the right card:

  • Amex Gold Business: 1 MR point per £1 = transferable to Avios, hotels
  • Capital on Tap: Effectively 1% cashback, no annual fee
  • Amex Platinum Business: 1-3 MR points per £1, plus premium travel perks

On £10,000/month in bill payments, that's 10,000+ rewards points per month — just for paying bills you were going to pay anyway.

Getting started

The setup takes about 10 minutes:

  1. Get a business credit card (Capital on Tap if you want fast and free, Amex Gold if you want rewards)
  2. Sign up with a bill payment service (we like Incredible for simplicity, but there are others)
  3. Upload your first invoice
  4. Choose your credit card as the payment method
  5. Done. Supplier gets paid, you get cashflow.

It's one of those rare business strategies that actually works, costs very little, and scales with your business.
