My region is Australia, and the accountant i am trying to assign is in Bangladesh. A region message comes up and she cant proceed when trying to login from the QB invite?

Hello there, jrichter-nguyen. 

The system can only add QuickBooks accounts within the same region. With regards to this, we can ask your accountant to sign up with the QuickBooks Online for Accountant AU version. Invite him/her again to proceed with accepting the invitation. 

You can check these articles for more details about adding an accountant:
