If you encounter the error message "Sorry, we don’t currently support connecting to a client’s QuickBooks Online company from a different region" in QuickBooks Online

Welcome to the Community, @geneveive728. Thank you for reaching out to us with your concern about connecting to your client's QuickBooks Online company from a different region. I understand the importance of resolving this issue promptly, and I'm here to assist you and share some additional information about this.

Presently, the ability to accept a client's invitation from a QuickBooks Online Accountant US version if you're from a different region and vice versa is unavailable. I know how you would want to have this ability, however, there are sections of the account that may vary like taxes that's why it's prohibited.

To confirm, yes, you can sign up for a US version as a workaround. You can refer to this article to create one: Sign up for QuickBooks Online Accountant US. 

Additionally, I've included an article that'll help you learn about the tools that are exclusively available for accountant users. These tools can help you enhance your bookkeeping and get things done efficiently: Use accountant tools and features in QuickBooks Online Accountant.

We're here to ensure a smooth experience for you and your client. Thank you for choosing QuickBooks Online, and we appreciate your time here in the Community forum. Should you need further assistance in signing up for the QuickBooks Online US version, feel free to leave a reply below.  It's our pleasure to be of assistance. Take care.
