Once Billie via Klarna is integrated, customers can select Billie's payment methods at the checkout. Klarna handles business customer identification by signaling the customer type: "organization" during session creation. Billie's integration via KCO uses the same logic and API as the B2C integration of KCO but requires a few changes to the fields to ensure a successful integration of Billie.

Please reference the publicly available documentation for the B2B integration of Klarna Checkout here.
