Hi there, @tony-herlihy-gma. I'll share some information about integrating third-party apps with QuickBooks.

There are a variety of third-party applications that works with QuickBooks Online (QBO). As much as I want to go further and help you, we’re unable to provide recommendations on which app to use, but I suggest visiting QuickBooks Apps to find one that will suit your business needs.

This is a place where you’ll find third-party applications that integrates with the online program. To expedite the process, type a keyword in the search box.

You can also check the customers’ reviews to get a better comparison of each app. Then choose the one that best suits your need the most.

Feel free to visit our Importing and Exporting Data page for more insights about managing data in QuickBooks. 

Please let me know if you have any other concerns. I want to make sure everything is taken care of for you. I'll be here to assist. Have a great day!

You can use Synder to connect and reconcile your Square transactions into QBO.

But if you only need to migrate the data, utilize another connector. There is a free plan with limited feature to use.
