QuickBooks on-line is lacking many features that are standard in the desktop program.  But a couple of month ago I had a call with support for some issue I had with the on-line version, for something I can do in the desktop version in 2 minutes, but could not do it on-line at all.  And I finally got an honest answer, that QuickBooks online is really not designed for accountants, it's designed more for people who don't really know what they are doing.  So, some of the features available in the desktop version are locked so the users don't screw-up the file too bad.
