Kustom Checkout is not compatible with the following e-commerce platforms:

If you are switching to one of these platforms from another provider, you will not be able to use Kustom Checkout with your store.

Each of these platforms has a built-in checkout system that is required for transactions. They do not allow third-party checkout solutions like Kustom Checkout to replace their native checkout.

While Kustom Checkout works with various e-commerce platforms, the restrictions set by Shopify, Wix, and Shopware v6 prevent external checkout solutions from integrating with their systems.

While Klarna Payments is compatible with some of these platforms, Klarna Checkout as a stand-alone solution is not. If you wish to use Klarna Payments through Shopify, Wix, or Shopware, you will need to apply for a new agreement directly with Klarna.
