I would like to know if there are any forms or customizations that can be done to allow an end user of WHMCS to make a payment without logging into the WHMCS client area? For some users I just want a web form that would allow them to enter an invoice number and send a payment without logging in.
I have not purchase or installed WHMCS yet. When I do, I will be using it with the Quantum Gateway.
Thank You
