Purchasing G Suite licenses
If you're on the Annual or Flexible plans and use up all your licenses, you can easily purchase more. We increase your monthly payment to cover the new licenses.
Required Permission: Assets Manager
You must be assigned access to the specific billing profile under which the domain is managed in order to purchase a license.
Within the CMP, select Billing from the top navigation bar and then select Assets. The CMP will take you to the Assets page.
From the Assets page, select Google Workspace from the left-hand menu:
You can see the number of licenses in use next to each Quantity label.
When you have located the subscription you would like to modify, you can add or remove as many licenses as you like, using the -1 and +1 buttons, respectively.
To apply your changes, select the APPLY button in the bottom right-hand corner of the card.
If you are purchasing additional licenses, you will be prompted to approve the purchase before continuing:
If you remove licenses, you will not have to pay for the licenses available if you aren't planning to use them. The charges will be deducted from your account as reflected in the next month's billing to your organization.
Only FLEXIBLE plans allow you to decrease the number of licenses. For more information, please review the Google documentation.
