This is beyond ridiculous - paying customers have been asking for this feature for YEARS.  Other platforms, including open-source systems (e.g. Invoice Ninja, from which I'm migrating) have this feature and for years now.

The utter disrespect of Intuit for it's customers' requests is appalling - we keep getting canned responses that provide no benefit other than to prove again and again that QBO development cares nothing for it's user base.

Having implemented this type of feature in my own development before, it's pretty low hanging fruit when you've got predefined variables.  What exactly does development spend their time doing???  It's not like new useful features are pushed out on any kind of regular basis.  Considering the monthly cost of QBO, you'd think after a reasonable period something would be done - and waiting years doesn't seem like a reasonable amount of time.

Suggesting using a recurring billing app as a solution is a cop-out for something this simple.  Shame on you, Intuit.  This just reinforces the general perception that Intuit cares about nothing except conning new users into moving to their platform and then milking them for all it's worth.  Maybe stop trying to aggressively push customers into buying more products and start actually implementing features users are actively asking for.
