How to change country

Hello there, @AUSSIEAUTOMOTIVEREGINA.

Are you trying to change the country of your subscription in QuickBooks? If so, there isn't a way to directly change which country your account is set as within the system. 

I'd suggest creating a new subscription in QuickBooks then cancel the other account to avoid double billing. 

To create a new account, here's how:

1. Open this link: https://quickbooks.intuit.com/choose-country/.
2. Choose the country you want to subscribe to.
3. Select whether to subscribe now or use a 30-day free trial and the type of subscription you will be using.
4. Click Add another company, then enter your existing Intuit login credentials.
5. Follow the on-screen instructions to set up the account.

Then, import your customer, suppliers, chart of accounts, and products and services list from the old account. This article will guide you to import them: Export Then Import List Data Into QuickBooks Online.

Once completed, you can now cancel the other subscription. I've got you this article for the detailed steps:  How To Cancel Your QuickBooks Online Company

However, if you meant something else, I'd appreciate any extra details you have so I can provide the steps to move forward. Looking forward to your reply. Enjoy the rest of the day.
