The functionality that is being requested is also something I have sought as well.  If Quickbooks wants to truly help business owners, we must have the reporting we need.  Cashflow is one of the most important aspects of running a business, so knowing when we need to follow up with a customer regarding payment is critical.  I don't particularly care how a client has paid over the life of their relationship.  Let me know how they're paying in time periods that matter to me so I can make informed decisions.  Please make this a priority!!
