Ask your client to create a new email address and invite it as the new Primary Admin. Then they can try to invite you as an Accounting Firm. 

Thank you. I will give that a try. 

I understand you're facing a frustrating issue, pingrong. Subscribing to QuickBooks Bookkeeping service doesn't affect this matter. Let me connect you with the appropriate support team to proceed with the next steps and provide updates regarding your ticket.

You can contact our Live Support Team during their support hours. They have the tools to securely access your account and conduct further investigation. Here's how to reach them:

2. Click the Help button at the top right corner.
3. Go to the Search tab and enter your concern in the search field.
4. Select Contact Us and choose a way to connect with us.

Additionally, if you need to manage users, you can see this article for more information: Manage user roles or permissions.

Don't hesitate to add another post or reply on this thread if you have more questions about adding your accountant or managing your QBO company and transactions. We are always available to assist you.

I have talked multiple times on the ticket to the support team.  

So far, the support team says that they can't do anything while the engineers team is investigating. 

It's almost a month since the first ticket.  The next scheduled update is March 15th. 

I mean, how difficult is this?
