Can I import dat from VT Transactions+ ?

Welcome to the Community, @pstrangward.

Currently, you need to find a third-party app that can help you migrate data from another software directly to QuickBooks Online.

Also, you can consult your software support to ask for options and assistance in migrating data.

Another option is export the data to a supported file type in QBO and import them.

Additionally, here is an article that contains common questions about importing data to QuickBooks Online: Common questions about importing data to QuickBooks Online.

Lastly, refer to this article for QuickBooks Online how-to videos: Get Started videos.

You can purchase a 3rd party conversion service or use an importer tool.
