Conversion manger to QB

One of my clients is planning on moving to Intiuit QB to manager due CRM integration. Is there a easy way that i can get the conversion done.

Can we download reports in CSV in Manager?

You can export any report in CSV format but don’t expect Quickbooks to magically be able to import anything. Typically when changing accounting systems, you normally start with opening balances. You don’t migrate history as it usually requires a lot of effort.
