Master Plan Instances
A Master Plan Instance acts as a container for billable and non-billable services.
Master Plan Instances can be assigned to and removed from an existing account on the Plans screen within the Accounts section.
Each master plan instance purchased is given a unique Plan Instance ID for tracking purposes. When multiple units of a master plan instance are purchased, each unit is also given a unique Plan Unit Instance ID for tracking purposes.

Note: The Aria Customer Care Portal offers an updated, more refined view of Subscriptions.
