Hello cbeck1,
Welcome to Community! I can understand the importance of managing user access in your books. QuickBooks Online lets you manage user roles and permissions when changes are necessary. I would be glad to help!
As the Primary Admin on the account, you'll be able to add, edit or delete users. To learn more about setting user roles and permissions, click here.
If you have any other questions, please don't hesitate to reach out. We would be happy to assist!
