Hello! How to accept the accounting invitation from US QBO? I'm in Canada

Hello Galina6V,

Welcome to the QuickBooks Community. It's important you get the help you need so you can continue to focus on your business with peace of mind. Rest assured, I'll be happy to share more info so you're on the right track. 

In order for you to accept an invite from the US QBO, the admin of that account would have to send an invite to you via email. Since US QBO and QB Canada are separate, you can still accept the invite using the link in the invitation email. Let me know if this info helps you. You're more than welcome to ask other questions in the comments below. I've got your back. 

When I try to accept the invitation, I have the message "Sorry, we don’t currently support connecting to a client’s QuickBooks Online company from a different region"

I see. What happens when you try to accept the invite while using a private/incognito browser window?

You have to sign up a new QBO Accountant US version with another email address to accept that invitation.
