If it fits, it’s Kustom
We're the checkout solution behind Europe’s biggest brands—fully customizable, all-in-one, and made to convert.
The Kustom story
Kustom became an independent company in 2024 after Klarna Checkout earned universal acclaim—so much so that its team knew it deserved a venture of its own. Now, as Europe’s leading checkout solution, Kustom has grown to over 90 experts, all committed to delivering a checkout experience tailored to every business’s unique needs.
With a merchant-first approach, Kustom offers unmatched control, flexibility, and scalability—empowering businesses to grow on their own terms, without compromises or being locked into a closed-loop solution.
From fast-growing brands to global enterprises, over 24,000 businesses worldwide trust Kustom to power their checkout.

Klarna has increasingly focused on and invested in developing Klarna as a payment method, which has led to a decreased focus on innovation related to the Checkout platform. Additionally, Klarna has deepened its partnerships with other Payment Service Providers (PSPs), and no longer sees the need to own and maintain the infrastructure for Checkout themselves.
