(Electronic-BUSINESS) Doing business online. The term is often used synonymously with e-commerce, but e-business is more of an umbrella term for having a presence on the Web. An e-business site may be very comprehensive and offer more than just selling its products and services. For example, it may feature a general search facility or the ability to track shipments or have threaded discussions. In such cases, e-commerce is only the order processing component of the site.
