I fill out the feedback form and NEVER get any status or feedback from my submission.  I never am notified when things are fixed.  I never get any admission of QB techs that it is a development bug. 

They spend the first 30 minutes trying to tell me the system is supposed to work some ridiculous way. 

I think your customers are QB's testers.  Do you test anything you develop before you go live?  do you test end to end?  or just see what's on the screen and think all is well? 

I have seen 3 different versions of a sales receipt and pledge in 3 days.  Do you know what does to employees who only know they are to fill out the forms in specific ways?  

I agree with the poster....stop MESSING with a LIVE system daily.  Do 1 formal release a month or quarter and tell your customers what the changes are!
