Zen Cart is a PHP e-commerce shopping program. Built on a foundation of OScommerce GPL code, it provides an easy-to-setup and run online store. Developed by people who make a living from selling online and who understand what the merchant really needs. Zen Cart™ truly is the art of e-commerce; free, user-friendly, open source shopping cart software. The ecommerce web site design program is being developed by a group of like-minded shop owners, programmers, designers, and consultants that think ecommerce web design could be and should be done differently.

Some shopping cart solutions seem to be complicated programming exercises instead of responding to users' needs, Zen Cart™ puts the merchants and shoppers requirements first. Similarly, other shopping cart software programs are nearly impossible to install and use without an IT degree, Zen Cart™ can be installed and set-up by anyone with the most basic web site building and computer skills. There are hundreds of shopping cart programs available, but none come close to offering the level of options, features and support available with Zen Cart™. Even the commercial programs have a hard time competing.
