A checkout revolution, step by step
Klarna launches an all-in-one checkout (KCO) with address pre-fill and flexible payment options, setting a new industry standard.
KCO becomes the number one checkout in the Nordics.
KCO allows merchants to sell in 170 markets, reaching shoppers worldwide while continuously refining and integrating the checkout experience.
The checkout’s success shows there’s a need for a dedicated home built around merchants and their long-term growth.
Klarna Checkout becomes Kustom, an independent company giving merchants more control, flexibility and scalability than ever before.
Kustom Mobile Point of Sale debuts, uniting online and in-person payments while the checkout solution evolves with more ways to pay, more markets and more currencies.
