osCommerce Templates are ready made solutions for on-line shops.
The store management and complete Admin Panel, or store back-end, is free from osCommerce.com and available immediately (The back-end refers to the place where you add products, manage inventory, shipping and all things behind the scene as with traditional brick and mortar stores. Your customers don't see this part of your store operation.)
osCommerce is the leading Open Source online shop and e-commerce solution that is available free under the GNU General Public License. It features a rich set of out-of-the-box online shopping cart functionality that allows store owners to setup, run, and maintain their online stores with minimum effort and with no costs, license fees, or limitations involved.
