The business market consists of organizations that acquire goods and services used to produce other products or services for sale. It differs from the consumer market in several ways: it has fewer but larger buyers, close relationships between customers and suppliers with suppliers frequently customizing offerings, and purchasing done by trained agents. Business buying is also influenced by technical experts and senior staff through multiple sales calls. Demand depends on end consumers and is inelastic, and small consumer changes can cause large fluctuations in business supply.
