Best card payment setup for UK online businesses 2026

For UK ecommerce stores, marketplaces, subscription billing, donation platforms and any business taking card payments via a website checkout. Payment gateway rather than physical card machine. The right answer depends on your platform (Shopify, WooCommerce, custom), volume, B2B-vs-B2C mix and whether you also trade in-person.

FAQs

What is the best card payment setup for a UK online business?

Depends on platform and volume. Shopify stores: native Shopify Payments (powered by Stripe) is the strongest at 1.5% + 20p plus avoids Shopify's alternative-gateway surcharge. Tech-led custom checkout: Stripe Checkout (1.5% + 20p) wins on developer ecosystem. Click-and-collect retail: Square Online plus Square Terminal (shared inventory). Above £1m monthly: Adyen Web on bespoke interchange-plus pricing.

Do I need a different acquirer for in-person and online sales?

No, ideally not. Omnichannel acquirers (Stripe, Adyen, Square, Worldpay) run both rails on one merchant agreement, giving you one statement, one settlement schedule, one chargeback workflow and one set of reconciliation. SumUp, Dojo and Tide are in-person-led with weaker online stories; Shopify Payments and GoCardless are online-only. Match the omnichannel acquirer to your dominant channel.

What is the difference between card-present and card-not-present pricing?

Card-not-present (online) transactions carry higher interchange than card-present (in-person). UK consumer-debit online interchange is around 0.2% (same as in-person), but the acquirer markup on online is typically 0.3% to 0.7% higher to cover the increased fraud and chargeback risk. Expect 0.3% to 0.7% more on your online rate vs your in-person rate from the same acquirer.

Does MerchantHQ cover online payment gateways too?

Yes. We work the 80+ UK acquirer panel, which includes 8 online gateways (Stripe Checkout, Adyen Web, Shopify Payments, Square Online, GoCardless, PayPal Checkout, Opayo, Mollie) plus 12 high-risk specialist online acquirers. See /online-payments/ for the full set.
