I'm done with the constant instability, poorly implemented changes, and "improvements" that were thought up by some programmer who's never actually done accounting. 

Every day is like playing Whack-a-Mole to figure out what Quickbooks has screwed up today. 

I'm very much aware of how much hassle it is to convert to a different accounting system.  That's what has kept me hanging on this long, but the time has come.  I have three clients that all use QB and will be moving all of them to something more stable.
