A nickname that describes business-to-business relationships or applications. Many Web sites focus on B2B solutions that cater to a vertical market, such as healthcare or automotive. These sites are for businesses (think wholesale), and only other businesses can access them or make purchases.
Similarly, a B2B auction is used to liquidate unwanted capital assets, dispose of excess inventory, and buy or sell equipment, parts, other products, and services. One advantage of setting up a B2B Web site is the ability to streamline operations between two businesses that already have a relationship. Internet analysts predict that B2B will be the biggest sector on the Web.
