Purchase Process Services : ATG

ATG 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 ATG Commerce to customize a purchase process that fills all the
requirements of your sites.
