As others have also noted, not having this function is very disheartening and apparently a pure oversight by Intuit.  If the time that has been spent telling us how to do work arounds had been spent on creating a way to pay statement balances online, we could have all moved on.  The audacity of saying "We recognize that each company has unique needs..."  This should be fairly obvious that this is not a unique need!  This issue keeps being brought up in blogs, communities, etc. and still nothing is done.

Having also been Director of IT for a public company, I realize that there is always more to it then the user can see.  However, if you can pay an invoice on line, paying an open balance isn't that much of a difference - you have the same database just a different record.  I've been involved in multiple system implementations over the years and this has always been a software requirement not a "nice-to-have".

Help us be more efficient and get this fixed sooner than later.
