Please note "fees"/"dues" are used here interchangeably: In Membership Export (or any other export that contains Membership data) there ought to be a way to pull the "balance due" on membership fees. Currently you can enter a Dues amount, and you can link gifts to the membership (which work similar to Pay-Cash/Pledge link; you're not creating a new record but linking records). It seems like, if people are making payments to their membership fee in INSTALLMENTS (especially for larger membership fees), there should be a "balance due" amount FIELD, so there is a way to pull that data into an Export.
