A client uses paymentech and I am looking for a shopping cart script (must be php/mySQL) that works with paymentech. I was planning to use x-cart and have him manually charge credit cards, which is how he is currently doing it. However, I would like to make this easier for him. Any suggestions?

Thanks!

I've never seen a cart that supports it. Your best bet is to get the X-cart developers to write a module for it.
