Invited me as an accountant user with the same email address to my regular QBO access. why I didn't receive the email invitation as an accountant user?

Thank you for letting us know about this concern, emint. Allow me to share some information on why you didn't receive the email invitation as an accountant user in QuickBooks Online (QBO).

I agree with what 4Gal said. When invited as an accountant user with the same email address as your regular QBO access, you may not receive the email invitation due to a specific process. The system may have identified your email address as an existing user and won't send a duplicate invitation. In this case, you can access the company file by logging in directly to your QBO Accountant account with your existing credentials.

I'll be here if you still have further questions regarding accountant users or other QuickBooks-related concerns. I'll be happy to assist you. Take care.
