We believe the best solutions aren't built in isolation. Kustom gives merchants the freedom to shape their own checkout by connecting to a growing network of 140+ partners. We handle the complexity behind the scenes, making sure every shopper enjoys the best possible experience. That way, growth happens freely, without compromises or closed loops.
From fast-growing brands to global enterprises, more than 24,000 businesses worldwide trust Kustom to power their checkout.
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. The checkout solution continues to evolve with 7 new payment methods, more markets and more currencies.
