A sales representative is a person employed to represent a business and to sell its merchandise to customers in a store or to customers who are visited. Sales Representatives play a significant role in the success of their individual companies. Regardless of the type of product or service they sell, their main duties are to interest buyers and purchasing agents in their companies’ merchandise or services and to address clients’ questions and concerns. Sales Representatives may showcase their products and advise clients on how using these products can reduce costs and/or increase revenue. Sales Representatives often spend time traveling to and visiting with potential buyers and current clients.
