If a client is going to completely shut down their Google Workspace/Gsuite email accounts, you will do this at MediaTemple if we are the ones billing them. Just login to MediaTemple>Billing>Request to Close Services
The service will be Google Workspace Business Starter. Find the client’s domain and it will show you the next renewal date. Set a reminder to make sure the service ends.
If a client is looking to just remove one or more email accounts, but leave the rest operational, you’ll need to make sure they delete them from the Google Workspace Admin first and then you have to get on chat with MT support in order to have the slots removed. Otherwise, they/we will still be charged for them.
