Tom makes a great point – there is a huge difference between an accounting package and a management program.  QuickBooks primary function is to provide you
with the tools for IRS reporting using generally accepted accounting principles
(GAAP), which are standards and detailed rules for financial reporting which
may not mend well with how to manage your shop. 
I have had long discussions with my accountant, who not only is a CPA
but also holds an MBA from University of Pennsylvania’s Wharton School Of
Business, he professes that while QuickBooks is excellent for keeping track of
finances, it is not the best tool for strategic management especially in a
niche business such as needed in an Automotive Repair Shop. 

We need to always have the right tools for the job that
would mean having both programs in your electronic tool box (computer) – My
recommendation, select a premier management program and an accounting
program…..

This all starts at the grass rots level.  I would recommend getting involved in your local technical school’s automotive  advisory boards – this is the group that reviews the curriculum and program.  Two things happen, you get to know the instructor (which helps when coming hiring time) and you help them to better understand the aftermarket needs as well.  Hope this helps.
