my account thinks i'm in Britain and using the GBP. i'm not but it won't let me change my address. why won't it let me change my address?

Hello there, Dev. It appears you might have signed up for the QuickBooks Online UK edition. When this happens, QuickBooks locks your currency and tax settings based on the region selected at sign-up. Because of this, the system will not allow you to enter an address outside of the UK once the account is created.

Since regional settings are permanent, you may want to consider cancelling your current subscription and starting a new one for the correct region. I also recommend contacting our Live Support team for real-time assistance and to verify your current subscriptions. When you restart the sign-up process, please ensure you select your specific country from the list.

Once that is settled, you will also have to manually transfer any data you entered in your UK version of QuickBooks to your new QuickBooks account, as automated data migration between regional versions is not supported. 

From there, you can set up your new account to better suit your business needs. You can follow the steps outlined in this article to get your new account up and running: Get started with QuickBooks Online.

We’ll keep this thread open if you have any other questions.
