SAP E-Commerce and Web CRM: The steps that a shopping cart takes during the shopping and checkout procedure: fill cart, select checkout, enter address, enter CC, select shipping method, and so on. Customers can modify this flow to meet their needs.

Web sites may want to have customers enter their address before they can select a shipping method. This way, if a customer lives in Hawaii and the Web store is in New Hampshire, UPS Ground will not display as a possible shipping method.
