Klarna's pay after delivery option allows customers to have their order delivered to them before they have to pay. Once the order has shipped, they will receive an email with a link to pay. They'll have up to 30 days to pay, depending on what was offered at checkout.
Klarna’s pay over time option is a revolving line of credit similar to a credit card, giving customers the ability to spread their payments over time. Klarna account holders can use their account to make purchases with any of Klarna’s partnered merchants who provide the pay over time option at checkout.
