Requiring payment of a minimum deposit for special order.
In our business we have lots of special orders (really back orders from the vendor). We require 100% payment for a special order. However, today, our cashiers sometimes forget to add the deposit and the special order is accepted without payment. In our previous system, we could specify a minimum payment for a special order (or a layaway) and this was included in the total due without having to remember to directly apply a deposit to their credit account. It also seems that if you add the deposit, then return to the sales ticket, the deposit is removed.
