I'm not really sure if this is possible. What I want to do is basically build a collections site. I want to have a single product - loan payments - and I want to have the client enter all sorts of information (ie: customer name, loan number, last 4 digits of social, etc.) along with the payment. Any thoughts on how to get started with this? Is this doable in Zen Cart, or do I need to go with a different solution? TIA!
