Hello there, kgorton.
I'm here to clear things up for you about the QuickBooks Online (QBO) to QuickBooks Desktop (QBDT) conversion process.
We have a guide to help you with the process of converting your Online data to the Desktop version. It comes with a migration tool to assist you as well. To get started with the conversion, you'll want to follow the steps outlined in this article: Export and convert your QuickBooks Online data to QuickBooks Desktop. It should be noted that both programs have different functionalities and features, so there will be limitations to the conversion process. This article highlights those limitations: Limitations when you convert from QuickBooks Online to QuickBooks Desktop.
Currently, we're unable to suggest which third-party app you should use to convert. You can look for an app that integrates with conversion in QuickBooks. You can also go to the Apps menu in your QuickBooks account and look for an app from there.
You can also check this article for any apps you can find that is integrated with QuickBooks: QuickBooks App Store.
Please let me know if you need anything or have questions. I'll be more than happy to assist. Have a great day.
