How to invite an accountant to access my QB account? I cannot find the "my accountant" tab on the left panel as mentioned in the tutorial video.

If you couldn't find it, your QBO version doesn't provide the feature. Where is your company located?

I have here another way to invite your accountant, accounting417.

1. Click the Gear icon and select Manage users.
2. Select the Accounting firms tab.
3. Select Invite.
4. Enter your accountant's info and select Save.

This emails an invite link to your accountant with steps for how to connect to you from QuickBooks Online Accountant. If your accountant doesn't have QuickBooks Online Accountant, there's a link in the invite for how to sign up.

Let me know if you need anything else.
