How do I distribute multiple subscriptions?

You can purchase multiple subscriptions, and the e-mail address where you make that purchase becomes the Account owner. You can also add multiple users to the 'Members' section and choose which role they get: Company Admin or Product user.

The Company Admin can also add users if they log in with their Trimble ID and choose the account assigned to them by the Account Owner. Added users with the role 'Product user' only see their product in the Account management portal, so that they can download SketchUp Pro themselves or have to de-authorize their Devices. (Account owners and Company Admins cannot do that for them.)

While adding the users you can already assign the product, do this later or change it:

Note: A SketchUp Subscription is personal, so in the name of the user. If it is a new Trimble ID, it still needs to be activated!
