Subscriptions describe a periodic billing for either physical or digital products. The amounts can be variable or fixed.

Subscription and Soft Subscription models

The classic subscription model binds the customer by notice periods or minimum terms. Billing takes place at fixed intervals. The soft-subscription model, on the other hand, gives customers a certain amount of freedom in the event of notice periods, delivery intervals and terms. The settlements differ by fixed amounts (fixed billing) and consumption-related amounts (metered billing). In part, these forms of billing can be combined, for example, a fixed monthly base charge with a usage-based component. There is also a trial subscription and a freemium model - here a free basic service with premium services is extended.
