Umbrella memberships for Restrict Content Pro.
This Group Accounts add-on allows you to sell group memberships with multiple members through Restrict Content Pro.
With Group Accounts, a member can register an account that includes a set number of seats for “sub accounts”. Once registered, the group owner can then add or import accounts in order to give membership access to members of their group.
For example, a school teacher might register a group account for a class and then add each student in the class as a member of the group, granting each student access to members-only content and resources on the website.
Billing and account control (cancellations, upgrades, etc) is limited to group owners, meaning group members do not ever need to enter any payment details or worry about the status of their account. This makes it easy for organizations and other multi-member groups to manage access for their members without requiring that each member maintain their own account.
