I tried to use REWIND App, but failed due to region, when i ask REWIND why, they says: They only provide sevice to QBO:USA, UK, INDIA, and Austrilia, Canada....

Hi there, Buck.

I'd like to help with your concern about adding a third-party app in QuickBooks Online. This feature is currently offered in the following regions:

• USA
• UK
• Canada
• India
• Australia
• France

I checked the Rewind app and it looks like it offers data backup services. Rest assured that QuickBooks Online saves your data automatically. We also use the same level of security used by banks and financial institutions. Here's an article for more details: Do I Need To Back Up My Data With QuickBooks Online?.

I'd also recommend sending feedback or feature request directly to our engineers. Here's how:

1. Go to the Gear icon at the top, then select Feedback.
2. Enter your comments or product suggestions.
