I have been working on client's qbo version-I am trying to add them to my qboaccountant-so that I can undo some recon. etc. I sent myself an invite-it will not connect?

I've got you covered, @jmassimo.

You'll want to accept the invitation first to successfully connect to your client's QuickBooks Online (QBO) account. An email invitation will be sent to the email address you enter when inviting yourself as an accountant to their QBO. If you encounter any issues accepting the invitation, let's check your sign-in info. Here's how:

1. Open the invite email.
2. Select the Accept Invitation.
3. Sign in with your existing user ID and password.

If you still can't connect to their company file, you can read this article for more troubleshooting steps: What to do if you can't accept client invites in QuickBooks Online Accountant.

Once you're already connected to your client's QBO account, you can now proceed with undoing their reconciliation. For more guidance with the steps, feel free to check out this article: Undo a client’s reconciliation in QuickBooks Online Accountant.

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response. Have a great day.
