We have a customer who has prepaid a percentage on a large sales order.   The customer has requested to see the prepayment on each line item that gets invoiced.  How does this get set up in Evo?   We want our cost to be the full cost, not the reduced cost.
 
I thought of using the discount column but that affects our cost and I can't seem to change the name from "Discount" to "Prepayment."
 
Any input would be very helpful!
