Move from QBO to QBDT serious limitation/problem
The details of products/services in bills and checks did not come through when the file was converted from online to desktop. Thousands of details are gone. I tracked small asset purchases this way, details are gone. Accruals: gone. Legal fees classified by matter: gone.
Also if you want to download the attachments, get ready to download 50 at a time if you're lucky. QBO on Chrome and IE, and the app cannot handle downloading 150-300 attachments at a time.
When moving the file from online to desktop be prepared to lose all your details entered in bills/checks using products/services. Make sure you save all the detail reports in QBO.
