A sales representative of a manufacturer is a company or individual who attempts to sell products to wholesale and retail buyers and purchasing agents of the products of the company he or she represents. A manufacturer's sales representative is an independent sales agent or agency that contracts with multiple manufacturers to provide sales services in a defined territory. The representative is paid a commission only on sales in the territory. The defined territory is usually on an exclusive basis, but there can be exceptions. Purchase orders are accepted by the manufacturer and are subject to the manufacturer's terms and conditions. Product is shipped and billed by the manufacturer.
