We want to offer EU and Swiss electronic signatures in our application. Is that possible?

As a customer, you must open two user accounts (ClaimedIdentity); each account is related to the respective signature type, i.e., the signing application must decide which account it sends a signature inquiry to. You can address both accounts via one interface, i.e., the same endpoint.

There is a service fee per account. 2 invoices are issued at the end of the month. Therefore two service contracts with two different configurations and acceptance declarations must be submitted. If you have two legal areas and two billing types, you still have only one interface (technical) but four service access interface points, and by this, four times a service fee. It doubles again to 8 ClaimedIDs if both signature levels (QES/AES) are planned with both billing types and jurisdictions.
