Cannot accept invitation as accountant - error Your user ID and/or password is incorrect. Please try again.

Let's work together so you can accept the invitation, kay-ewanzyen-koh.

I assume you use the same credentials for signing in to your QBO Accountant account, and you have no password issues with it. Therefore, please ask your client to delete the pending invitation and create a new one so that you'll get a new link. If you'll still have password issues, please contact our QBO Support to check this further.

Contact QBO Support:

1. Go to Help and choose the Search tab.
2. Click Contact Us at the bottom.
3. Enter a sentence to describe the issue and click Continue.
4. Choose a way to reach the team.

On the other hand, you can also check out the tools and features of QBO Accountant that you can use when auditing your client's QBO company.

Feel free to go back to this thread if you have other concerns. We'll be happy to help you again. Take care!
