Oracle ATG Web Commerce enables you to build sites that support simple or complex purchasing processes. A simple purchase process might provide customers with a single shopping cart, and enable customers to purchase products using a single payment method and to ship those products to a single location. In contrast, a more complex purchase process might include multiple shopping carts, payment methods, and shipping locations. You can use Commerce to customize a purchase process that fills all the requirements of your sites.
