Hi cast54541,
I'll take that you want to convert your QuickBooks Premier file to QuickBooks Online - Brasil version.
Currently, migrating QuickBooks Desktop to QuickBooks Online is available in the UK, US, and Canada versions. Since you have an International subscription, you may consider using a third-party application tool. I’m unable to recommend you an app, but I'd suggest checking the reviews from the other customers to help you decide.
Here's how to look for an app:
- On your QuickBooks Online account, click the Apps tab.
- Go to the Finds Apps tab.
- In the search tab, type in the app you're looking for or you can enter keywords.
Once converted, you can check this reference as a guide in getting started with QuickBooks Online: Get started with QuickBooks Online.
I'm always here in the forum to help fix your concerns. Feel free to mention my name.
