Well, if they'd make it easier
Workng for a company using Intuit Quickbooks for accounts and Sage for payroll on the desktop, we wanted to move that out to the cloud versions. For Intuit, it was "backup your local system, upload the file here, and 5 minutes later you are up and working on the cloud". Sage - "the systems aren't compatible. You will need to enter our cloud version as a new customer and set everything up again from the beginning".
At that point, are they surprised people start to look around at their options? If they'd made it easy, we'd probably just have gone ahead with Sage to save time, but if we've got to re-enter anyway, we'll have someone cheaper, thanks!
