Klarna vs Stripe: Which Is Better? (2026)

Stripe charges 2.9% + $0.30 per card transaction. Klarna charges merchants between 3.29%–5.99% + $0.30 per transaction depending on product and region. While Klarna can increase average order value, the per-transaction cost is significantly higher than standard card processing through Stripe.

Klarna's BNPL options (Pay in 4, Pay in 30 days, financing) increase average order value by 41% and reduce cart abandonment according to Klarna's data. Stripe processes payments but does not inherently offer conversion-boosting installment plans as a core product.

Stripe supports 100+ payment methods including cards, wallets, bank transfers, BNPL (including Klarna itself), and local methods worldwide. Klarna focuses exclusively on BNPL and direct payments within its own ecosystem.

Stripe's API, documentation, and developer tools are industry-leading. Klarna's integration is narrower in scope — focused on embedding BNPL widgets — and while functional, does not approach the breadth and polish of Stripe's developer ecosystem.

Klarna has 150+ million active users who browse and shop through the Klarna app. Merchants on Klarna get exposure through Klarna's shopping marketplace. Stripe is invisible to consumers — it powers the backend but has no consumer-facing brand.

Stripe offers subscriptions, invoicing, Connect for marketplaces, Radar for fraud, Tax, Terminal for in-person, Identity verification, and more. Klarna focuses on BNPL, on-site messaging, and its shopping app — a narrower but deep product set.

With Klarna, the merchant gets paid upfront in full while Klarna assumes the credit risk of the consumer's installment plan. With Stripe, chargebacks and payment defaults are the merchant's responsibility. This risk transfer is a significant advantage of Klarna for merchants.
