A business to business, or B2B sales representative is responsible for the sale of products between businesses. As a B2B sales representative, you can work for a manufacturer that sells to wholesalers, or a company that sells products directly to other businesses. This contrasts with a business to customer (B2C) sale, which refers to single customers buying products from store shelves or online. Your job duties include calling potential clients, pitching your product, and potentially managing their account. The qualifications needed for a career as a B2B sales representative include a bachelor’s degree, previous sales experience, and excellent customer service skills.
