Hi Yahal

The conversion will not work properly as the Desktop and Online functions are different. Online does not have a full stock function, you cannot process part/multiple deliveries on a single purchase order neither will it part/multiple bills against a single purchase order. This function has been on desktop for over 20 years online is a step back in technology it is only good for new startups not million pound turnover well established companies. 

Also as Desktop ceased payroll two years ago that data has already been made unavailable so will not transfer. 

Sage is also heading for the cloud, the stock is an add on but pointless taking that route if it will only be around for a year or two.

Surf accounting are cloud based and heading towards have QBDT functions I'm in cotact with them but this does not solve the issue of keeping current data. It will only be fully available if the sotware you are transferring to has the same functionality. Changing to another software is not the issue here it is access to existing data that is the issue.
