People who shop online are most familiar with this type of website. A transactional site may be an electronic storefront for a brick-and-mortar retailer or a catalog business, (e.g., Lands’ End), or a manufacturer showroom for those wishing to sell directly to the public (e.g., Dell Computer). Transactional sites conduct full “end-to-end” transactions via the website, allowing customers to search for, order, and pay for products online as well as allowing them to contact the company for after-sales service. The most sophisticated sites create efficiencies by integrating the transaction process with back-office systems such as accounting, inventory, sales and others (e.g., Amazon).
