Add Google Apps services to your account
When you sign up for Google Apps, core Apps services are added to your Google Account and become available to your users. These include Gmail, Google Calendar, Google Drive, Google Hangouts, and more. You can add more Apps services, for example, to upgrade to Google Groups for Business or purchase additional Drive storage for users. Or if you remove a core service you don't want to use, you can add it back later.
To add a Google Apps service:
- Sign in to the Google Admin console.
- On the dashboard, click Apps, then click Google Apps.
- Click . A page appears listing the services that are available to add.
- Click Add it now under the description of the service you want to add.
After adding a service, you can control who uses it. Just turn the service on or off for those people in your Google Admin console. For details, see Control who can access Google services.
