Procurement involves obtaining goods and services from external suppliers. In small organizations, procurement is centralized under one person, while in larger organizations it can be centralized or decentralized across departments. Key procurement staff include the Chief Buyer who oversees major purchasing decisions. The procurement department determines items to purchase based on business needs, liaises with other departments on their requirements, and manages inventory levels to avoid stockouts and maximize storage space. Maintaining accurate inventory records allows the business to track market trends and order replacement stock efficiently.
