Greetings, @rjkatz.
Thank you for posting in the QuickBooks Community. I'd be happy to help share some additional information about sending an invite to your accountant.
Please take note that inviting or removing an accountant user from a QuickBooks online subscription requires admin rights. Only the Accountant, Master administrator, Company Administrator has this access.
The following article contains additional information about this, as well as steps based on what Manage Users screen you have: Add or remove an accountant user in QuickBooks Online.
For additional help, feel free to reach out to our Phone Support. Our phone agents will be able to help you get to a resolution quickly.
That should do it. Feel free to drop a comment below. I'll be happy to help you out.
