What is Zen Cart?

Zen Cart is an open source online store management system. It is PHP-based, using a MySQL database and HTML components. Support is provided for several languages and currencies, and it is freely available under the GNU General Public License.

Zen Cart branched from osCommerce as a separate project. Beyond some aesthetic changes, the major differences between the two systems come from Zen Cart's architectural changes (e.g. a template system) and additional included features in the core. Among the modules already included are a Gift Certificate/Voucher module which allows to create, send and manage the digital coupons. A module to sell downloads (pdf or other media files) is included as well.
