Klarna is a popular Buy Now Pay Later payment method available in 22 countries/regions. With Klarna, the customer can choose to:

  • Pay later: Pay after the goods have been delivered.

  • Pay over time: Pay in instalments over time.

  • Pay now: Pay the whole amount instantly, either by online banking or direct debit.

Before approving the payment, Klarna performs risk checks on the shopper. If successful, Klarna takes on the full fraud risk for the payment, and pays you up front.
