Your data doesn't have to be lost. You can convert QBO data to QBDT, or you can pull the entire GL into MS Excel or Google Sheets. There are ways to pull the data so you can easily import it to another system that will take data through excel or google sheets. And you can do this after you cancel your subscription as the data is still available for 12 months after cancellation.

In regards to this thread, I think my clients would prefer a longer turn-around time in exchange for getting the service for free.
