Zoho and E-commerce

I have a customer that has an art gallery in the center of the town.
He asked me to develop an application with Zoho and an E-commerce tool, so that he can sell through the internet with credit cards payment etc.

Is it possible to do it?
Are there any e-commerce site/tools that are zoho-compatible?
(Examples: ebay.com, cafepress.com or lulu.com)

Thank you for the answer.
