The Subscriptions feature is available in the Sales Pack extension.
The Subscription feature provides the ability to invoice customers on a recurring basis (monthly, yearly, etc.). It can be used for various purposes, like managing billing for a digital service, maintenance service, physical product replenishment, consulting, membership, etc.
Subscriptions are integrated with price books, allowing for flexible and customizable pricing.
A subscription billing cycle can be configured to align to specific days. For example, you may want to bill customers only on the 1st and 15th days of month. An alignment period, which is usually much shorter than the regular billing period, can be optionally prorated.
Updates to existing subscriptions can be automatically prorated, with the customer invoiced or credited accordingly.
