I am appalled this has not been addressed by the QBO team.  Several of my clients need this Invoice Date / Accounting Date feature for various reasons.  I am a QBO Certified Pro, a CPA, and I purchase QBO using their wholesale program.  Because this has remained unresolved, I may not recommend QBO to my new clients.  I am also contemplating having a conversation with my current clients about the possibility of migrating to different bookkeeping software.
