Simple subscription handling
A common use of Billwerk+ Payments and/or Billwerk+ Subscription Management (Lite/ Expert) is to have customers in own system and customer subscriptions in Billwerk+, where at any time a customer will have at most one active subscription.
This simple use case demonstrates how Billwerk+ can be used for signup, access control and subscription management without storing any data on own system except the customer with a unique id. At some point the solution could be extended to keep data on own system for quick access. This could be done by synchronizing data between Billwerk+ and an own system using webhooks.
