Best Business Credit Card for UK Amazon, eBay & Etsy Sellers (2026)

By Afshin · 9 June 2026 · 7 min read

Running a UK online store on Amazon, eBay or Etsy means constant cashflow pressure: you buy stock upfront (often from overseas suppliers in USD), pour money into ads to stay visible, then wait days or weeks for the marketplace to pay you out. The right business credit card turns that pressure into rewards. Here is what UK limited company sellers should look for in 2026.

The online seller's cashflow squeeze

Marketplaces like Amazon, eBay and Etsy typically hold your sales revenue and pay out on a schedule — often two weeks or more behind your actual sales. Meanwhile you are buying stock, paying for ads and covering fees in real time. That mismatch is the number one cashflow headache for UK sellers.

A business credit card with an interest-free period lets you fund stock and ads now, then repay once your marketplace payout lands — keeping you growing instead of waiting.

Stop losing money on overseas stock

If you source products from suppliers in China, the US or the EU, foreign transaction fees quietly eat your margin. Most cards add around 2.75% on every non-sterling purchase. Capital On Tap charges 0% FX fees on EUR and USD spend, so importing stock costs you less on every order.

On top of that, you earn 1% unlimited cashback on everything — including the thousands you spend on Amazon PPC, eBay Promoted Listings and Etsy Ads each year.

• 0% FX fees on EUR/USD when buying overseas stock
• 1% unlimited cashback on advertising and inventory
• Instant virtual card for online supplier and ad payments
• Credit limits up to £250,000 to scale inventory

Fund growth, not just survival

The sellers who scale fastest are the ones who can reinvest in stock and ads before the cash from previous sales has cleared. With a limit of up to £250,000 and an instant virtual card on approval, Capital On Tap gives growing UK sellers the headroom to buy bigger and advertise harder.

Transactions feed into Xero, so your cost of goods, ad spend and fees stay organised for VAT returns and profit tracking.

Eligibility and your £75 head start

Capital On Tap is available to UK limited companies, LLPs and PLCs registered at Companies House, with turnover of at least £24,000 and no unsatisfied CCJs in the last 12 months. The application takes about two minutes with an instant decision. Like most business cards, it requires a personal guarantee from a director.

Apply with referral code 2REFY893A52 to receive a 7,500-point welcome bonus (worth around £75) after your first transaction — a useful head start on your next stock order.
