Somehow we have techs/cashiers registering a cash payment as well as a credit card payment and it gets applied to the same invoice number for a customer. This is creating a credit balance for the customer, but I'm sure we only collected either the cash or the credit card, it was just not corrected (or not allowed to happen in the first place) by the cashier. It is creating a large "Payments that have not fully Applied" list. This creates extra work after the fact.
