Subscription

Summary

Subscriptions are a particular type of document that have a set of rules and directives that must be tracked and performed to verify their validity. Eg. Some manufacturers offer their documentation and manuals as a free resource, while others require a daily/monthly/yearly payment to have access to these goods.
The Subscriptions screen provides a way to assign subscriptions and its rules to one's own customer, as well as track and validate their expiry date.
