To distribute App Store applications and custom applications to Apple iOS and macOS devices, utilize Volume Purchase Program by integrating Apple Business Manager and Workspace ONE UEM.
The Apple Business Manager enables organizations to purchase publicly available applications for distribution. Any paid application from the App Store is available for purchase, in volume, at the existing App Store price. Custom applications can be free or purchased at a price set by the developer.
See Apple's website for the availability by country and for other details.
