1. Click on your name in the top right. Then Select "Account and Billing" from the dropdown.
2. On the second heading on the left hand side click the button that says, "Manage Subscriptions".
3. In this section you can add or remove admin users, SMS messages, storage, and AI. To add simply increase the number on the right hand side, check the box on the left and then hit "Submit". Removing subscriptions is the same process except you lower the number under the Quantity column.
