The agreement gives millions of Ebay users in the USA the opportunity to choose Klarna's services to pay for their purchases.
Klarna has been offered on Ebay in several major European countries since before.
"We are very pleased to now be able to offer Klarna's services to our customers in the USA. We have already seen clear positive results with Klarna in the UK and several European countries", writes Avritti Khandurie Mittal, global head of payment solutions at Ebay, in the press release.
According to Klarna, the partnership means "another step towards becoming an obvious part of how the world's largest retailers shape their customer offerings – with sustainable payments in focus".
