FAQs

What is the best UK payment infrastructure for a marketplace?

Stripe Connect is the default for UK marketplaces in 2026: split payment at transaction time, seller KYC orchestration, embedded payouts, multi-currency support. Adyen for Platforms wins above £5m monthly platform volume. Square for Platforms for smaller community marketplaces with click-and-collect.

How does a UK marketplace handle seller KYC and payouts?

Stripe Connect Express handles seller onboarding via a Stripe-hosted KYC flow (passport, beneficial-ownership, banking details). Stripe Treasury handles payouts to the seller's bank account. Platform takes commission at transaction time; the rest goes to the seller balance, paid out daily or weekly per the platform's schedule. Compliance is on Stripe to the regulator; the platform stays compliant by using Stripe's flow as-designed.

Is a UK marketplace operator regulated as a payment institution?

Maybe. If you handle customer funds (money flows through your account before going to the seller), you typically need an FCA Payment Institution licence or use a regulated provider like Stripe Connect or Adyen who provide the licence layer. If you use Stripe Connect Standard accounts (customer pays the seller directly via the seller's own Stripe), the platform is not handling funds and avoids the licensing requirement.

How do UK marketplaces handle chargebacks between buyer and seller?

Stripe Connect lets the platform set the chargeback liability split: 100% to seller (platform protected), 100% to platform (seller protected), or shared. Most UK marketplaces put liability on the seller by default since the seller controls the listing, the delivery and the customer interaction. MerchantHQ helps configure this and handles disputes when they cross to the platform.
