The issue is with "partial payments" in the ledger under "Batch Insurance Payments". When I entered the "additional payment" today (January), the final tally of the payments included the payment from October.......so there was no way I could balance. Sadly this happened on a "U" patient (alphabetically), so I had already entered $6000 worth of payments from "A-T". Will have to delete all payments and enter them as a NON BATCH. This is not as good for our book keeping. Hopefully you will find a fix for this in the future. Very Frustrating.
