Mobile Device Management (MDM) solution like Apple Profile Manager

Streamline Your Distribution
Get apps and books into the hands of your users quickly and easily with an MDM solution. You can purchase apps or books in volume, then assign them to your users on iOS 7 or later or on OS X 10.9 or later via a Mobile Device Management (MDM) solution. When you assign an app to your users, they can use it on all of their devices. When they no longer need the app or when they leave your organization, you can then reassign it to a different user.
To get started, invite your users to enroll through your Mobile Device Management (MDM) solution. All they need to participate is an Apple ID and a device with iOS 7 or later or a computer with OS X 10.9 or later.
How it Works
    1. Invite users to participate.
    2. Assign apps and books to participate users.
    3. Revoke and reassign apps as needed. Book assignments are permanent and cannot be revoked or reassigned.
User Requirements
    An iOS device running iOS 7 or later.
    A Mac running OS X 10.9 or later.
    An Apple ID that has been set up for use on the iTunes Store.

Managing Content
You can easily manage content using a Mobile Device Management (MDM) solution. There are a wide variety of MDM solutions available for iOS and OS X, including Apple Profile Manager. MDM solutions can integrate with your organization's directory system and manage users and groups. Check with your MDM provider to see if they support managed distribution for the Volume Purchase Program (VPP).
To get started, go to your Account Summary page and generate a token which can link your VPP account to your MDM server. Once your MDM server and VPP account are linked, you can invite users, assign apps and books, and revoke and reassign apps directly through the MDM solution.
