I see where you're coming from, @Jaynee. As a customer, I would also like to keep my company files updated in QuickBooks Online (QBO).
Let me share some insights about third-party applications and limitations when moving your QuickBooks Desktop (QBDT) company file to QuickBooks Online (QBO) so you can manage your financial data accordingly.
When you switch from QBDT to QBO, there'll be differences in how your books appear. Transactions like invoices move to QBO. However, some of its data like subtotals and progress invoices don't move. With this, you may opt to manually import them or utilize a third-party application to do it for you.
If you wish to know more about how your books move from QBDT to QBO, please see this article: Learn how features and data move from QuickBooks Desktop to QuickBooks Online.
On the other hand, QuickBooks advertises apps to guide our users on how to optimize their experience with the system. While I can't recommend which app you should use, I know the resources to help you look for one. Explore the Apps menu within QBO or the QuickBooks App Center to do that. From there, you can read some user feedback about the app and other information like its functions, etc.
Also, you may want to check out this article with short step-by-step videos as your reference to guide you in getting started and using QBO to run your business: Learn about QuickBooks Online with how-to videos.
Please don't hesitate to keep me posted in the comments if you have other concerns about migration and data management in QBO. I'm always ready to help. Take care, and I wish you continued success, @Jaynee.
