To add a new payment (Down Payment or Installment) you need to first search the customer by NIC number. In the search result page (search.php) There is a link "Payment" for each sale of the customer. In the new payment page (new_payment.php), all the details (sales details, customer details, previous payment details, remaining payment details) are showing.
Following details need to enter as a new payment:
- Payment Date
- Value
- Payment Type (Down Payment, Installment or Other Charges)
- Payment details (mode of payment cash, cheque or credit card, etc.)
If you select Installment, the amount must be equal to the installment value defined earlier. There is an option to delete an entered payment. There are lots of functions in this page and maybe the most complex page of the system.
Source code of new payment page:
<?php include("header.php"); ?>
<?php
/*if(privileges('New Payment') != 'Valid'){
header("Location:main.php");
ob_end_flush();
}*/
?>
