I am using quick books advance but i am in Bahrain. is it ok to use it? and how can i change the address to bahrain.

Why did you choose QBO Advanced, not QBO Global version for Bahrain? Any specific reason?

Let me share details about the availability of the QuickBooks Online (QBO) Advanced plan, hanan2.

QuickBooks Online Advanced isn't offered yet in other regions. The option to change the region or country of your QuickBooks account is currently unavailable. You may consider canceling your account and signing up for QuickBooks Online International for Bahrain. 

Here's how to cancel the account:

1. Go to the Gear icon.
2. Select Account and Settings.
3. Click the Billing & Subscription tab.
4. In the QuickBooks section, choose Cancel subscription.
5. Click Continue to cancel, then select Continue to cancel again.
6. Follow the online steps, then hit Submit and cancel the subscription.
7. Click Got it.

Once done, you may subscribe to the International version of your home country by visiting this link: https://quickbooks.intuit.com/community/Getting-Started/International-versions/m-p/186273.

Please know that you're always welcome to comment below if you have other concerns or follow-up inquiries about managing your subscription in your QBO account. I'm just around to help. Have a great day.
