Hi there,

You've reached the right place for help. QuickBooks Online makes it easy to manage an Accountant User.  To remove the user:

1. Select the Gear icon at the top, then Manage Users.
2. In the Accounting firms section, select Accountant row, then choose Delete.
3. Select Yes to confirm

Here's how to add or invite an accountant:

1. Select the Gear icon at the top, then Manage Users.
2. In the Accounting firms section, select Invite Accountant.
3. Enter your accountant’s email address. Select Next, then Finish.
