To be clear, this post is meant to SLAM the QB software engineers and the company in general.  This is accounting software, and by definition must be 100% accurate.  The idea that it is importing duplicate data without any notification is UNACCEPTABLE.  Do these people understand GAAP, rules of accounting, or any other principles of accounting software?  Evidently not.  This community continually receives a response from someone at QB "informing" us on how to delete transactions.  I know how to delete %#$@ING transactions.  The problem is going back and determining which ones are duplicate, and how much time it takes.   My post, and this thread, is about duplicates from Chase, and it is a problem that is several months old.  If the people charged with fixing this problem worked in a real company that was held accountable internally, they would be fired by now.  Unequivocally fired.   Let's see if this stays posted.
