During Make Sale a customer has various options when paying their bill.
The Pay Balance option automatically creates a Bill Payment for the current balance on the customer account.
The other option is to make payment using the same dialog as above will appear allowing the choice of payment amount and invoice. A different customer may be chosen. This enables bill payment of multiple customers on the same Sale transaction.
