Business markets consist of organizations that acquire goods and services used to produce other products or services for sale or supply to others. Business markets have fewer but larger buyers than consumer markets. Relationships between suppliers and customers in business markets are typically close as suppliers must customize their offerings to each buyer's needs. Purchasing processes in business markets are professional with standardized policies and requirements that must be followed. Demand in business markets is often inelastic and fluctuating, depending on demand in related consumer markets.
