years, and it sucks. Tons of bugs. There is no difference between 2003 and 2005 version, but the company forces you to buy new version, otherwise, you can't use the payroll. All the new features, they talk about are nothing but fix for their old bug. I recommand MYOB if you are in US. In canada, use simply accounting.
Quickbooks suck ass.
