How often do I need to upgrade to a new version of QuickBooks Pro?
The specific answer would depend upon whether the latest version of QuickBooks has new features that you believe are important. Barring your need for a specific new feature, you can generally skip the new releases for two of three years. In other words, there isn’t anything wrong with QuickBooks Pro 2002 or 2003, so I you don’t need any of the new features that are in version 2004, then you don’t need to upgrade at that time.
