So, did anyone ever add a class field into the payment record(s)??  I too am trying to run reports by class and there is no good way to include the payments.  Please don't try directing me to the above mentioned links that claim that Quickbooks will apply the class from the invoice.  It doesn't.  Plain and simple.    Will there every come a time when we can actually create intelligent reports directly from tables within Quickbooks?  It's so frustrating to know that there is good data that has been entered, but the very limited customization options don't allow us to join additional tables/records that would provide the data needed.  I really don't want to have to download transactions with a third party app, just to build my own SQL database that I can use to create the reports I need, but it's starting to look that way.
