I'm looking for a freelancer who can integrate a payment gateway (PayFast) with WHMCS. If clients pay using the payment gateway, then their invoice must be marked as paid in WHMCS. WMHCS has been running for over 2 years. The plugin for the PayFast has been installed in WHMCS recently. The invoice provides the option to pay by PayFast, but it is not working correctly.
The developer documentation is at: [login to view URL]
VERY IMPORTANT: The freelancer must provide clear documentation with screenshots and step-by-steps on how it was implemented.
