Mail In Payment

Using Mail In Payment as a payment gateway allows you to enter client payment details that will display on the printable invoice. You can use this to display the address to which clients should send checks or other payment.

  • When you use this invoice, the system redirects the client to the invoice when it would normally send them to the payment gateway.
  • When you receive payment, you must manually add the transaction to WHMCS using the Add Payment section of the invoice.

This module and the Bank Transfer module are open-source, allowing you to duplicate them if you wish to offer multiple options. For more information, see Duplicating Modules.
