I am an accountant who has wasted several hours on trying to help a client transfer from Desktop to Online.  This process is very frustrating.  There should be more support from Quickbooks to assist with start up and transfer problems.  When you type "purgecompany" nothing happens.  You should be able to wipe out the company data and start again.  I will not be recommending QuickBooks to my future clients.  I will be looking for another software that has better customer support.  I am so frustrated.
