 is defined, an FS::cust_bill_pay record for the full amount of the payment
 will be created.  In this case, custnum is optional.
 
+If the additional field discount_term is defined then a prepayment discount
+is taken for that length of time.  It is an error for the customer to owe
+after this payment is made.
+
 A hash of optional arguments may be passed.  Currently "manual" is supported.
 If true, a payment receipt is sent instead of a statement when
 'payment_receipt_email' configuration option is set.
