Tradebank is a privately held international trade exchange founded in 1987. Headquartered in Canton, Ga., Tradebank operates in regions throughout the United States. In barter's simplest form, two businesses or professionals trade items of equivalent value. Tradebank, however, opens up a whole new dimension in trading. Now a company doesn't have to find another company that simultaneously needs its product or service. Only one trader's need is required to start the process and with the help of a trade broker, everyone comes out with something they need.
