who is in charge of purchasing in a company
Purchasing manager A Purchasing Manager is an employee within a company, business or other organization who is responsible at some level for buying or approving the acquisition of goods and services needed by the company. Responsible for buying the best quality products, goods and services for their company at the most competitive prices, purchasing managers work in a wide range of sectors for many different organizations. The position responsibilities may be the same as that of a buyer or purchasing agent, or may include wider supervisory or managerial responsibilities. A Purchasing Manager may oversee the acquisition of materials needed for production, general supplies for offices and facilities, equipment, or construction contracts. A Purchasing Manager often supervises purchasing agents and buyers, but in small companies the Purchasing Manager may also be the purchasing agent or buyer. The Purchasing Manager position may also carry the title "Procurement Manager" or in the public sector, "Procurement Officer". He or she can come from both an Engineering or Economics background.
Government procurement in the United States The authority to purchase is not one of the explicitly enumerated powers given to the Federal Government by Section 8 of Article One of the United States Constitution, but courts found that power implicit in the Constitutional power to make laws that are necessary and proper for executing its specifically granted powers, such as the powers to establish post offices, post roads, banks, an army, a navy, or militias.
