Please ensure, before purchasing QXpress, that your version of QuickBooks has the ability to synchronize with third party software (such as QXpress). You can find this out by selecting 'Edit', then 'Preferences' in QuickBooks, then locating the ‘Integrated Applications’ option. This functionality is essential to the synchronization of your customer and item data between QuickBooks and QXpress. ‘EasyStart’ versions of QuickBooks do not have this functionality.
