I am an accountant and I have accepted an invitation and now the Company does not appear on my list. How do I get it back?

Did the client remove you as an Accountant user? That's the first thing I would check.

Hi there, @kallen.

Thank you for posting here in the Community. I'm here to help check your client's company in QuickBooks Online Accountant.

If you are added as an accountant, you can check the client's company by selecting Client at the left pane and clicking on the drop-down arrow beside Go to client's QuickBooks.

However, if you're added as a company administrator, you can check the list of companies under Please select the company you want to open after signing into your account.

That should do it. Let me know if you have any other QuickBooks concerns by adding a comment below, I'm always here to help you. Have a great day ahead!
