Business buyers go through a decision process when purchasing goods and services. This process depends on the type of purchase, whether it is a straight rebuy, modified rebuy, new task, or systems selling. The business buying process involves multiple participants within the buying center, including users, influences, buyers, deciders, and gatekeepers. Several environmental, organizational, interpersonal, individual, and buyer factors also impact the purchasing process. The typical steps are problem recognition, general product specification, supplier search, proposal solicitation, supplier selection, order routing specification, and performance review. Institutional and government markets represent important sectors for organizational purchases.
