Selected wrong billing plan
When setting up billing for G Suite, I selected the wrong billing plan.
During billing setup, go back and select the right plan
If you haven't yet completed billing setup for G Suite, click Back in the setup window to go back and select the correct billing plan. Or restart billing setup and this time choose the correct plan.
After billing setup...
If you've completed billing setup, your options for switching plans depend on the plan you want to switch to and whether you're still in your free trial period. For details, see Switch billing plans.
