Apple Business Manager

Location-based licenses in Apple Business Manager
When you buy apps or books for your location, those purchases are seen by other Content Managers associated with that location. For example, if you purchased 5000 licenses for the Pages app, other Content Managers at your location can:
Transfer licenses to another location.
Download the token for those licenses and make assignments in your mobile device management (MDM) solution.
Licenses that are currently assigned in your MDM solution are still listed as assigned and are unavailable. When those licenses are unassigned, they are then shown as available for transfer in Apps and Books.
Note: Books obtained from the Books app, once assigned, become the property of the Managed Apple ID and can’t be reassigned.
