Klarna
What it is
Klarna Payments lets merchants add Klarna as a checkout option for web, in-app, and in-person purchases. After selecting Klarna, customers may pay immediately, later, or in installments. In the United States, Pay in 4 divides a purchase into four interest-free payments due every two weeks, with no fees when paid on time. Other listed choices include paying within 30 days, paying in full, and monthly financing over 6–24 months. The Klarna app is free to download and use; shoppers can manage payments, earn cashback at participating stores, track deliveries, compare prices, use loyalty cards, and shop in-store. Merchants can connect through APIs or plugins for platforms including Shopify, Adobe Commerce, Salesforce Commerce, and WooCommerce. Klarna also supports recurring and one-time payments, and provides merchant tools such as express checkout and on-site messaging. Its US Pay in 4 eligibility rules include age, residency, and payment-account requirements, and each purchase is subject to a new automated approval decision. Klarna has a free plan, while pricing is also listed as available on request.
