One platform for the store and the web shop
Online, Unzer offers a preconfigured payment page, SDKs, a REST API and plugins for shop systems, plus in-app payments and pay by link. In the store it sells the POS Go terminal and an iPad cash register, and for buy now, pay later a white-label option (Unzer). A merchant that sells in both channels sees its sales from both in one place. Ecommerce payments in Germany covers which methods German shoppers choose online.
