Procurement is the act of finding, acquiring, buying goods, services or works from an external source, often via a tendering or competitive bidding process. The process is used to ensure the buyer receives goods, services or works at the best possible price, when aspects such as quality, quantity, time, and location are compared. Corporations and public bodies often define processes intended to promote fair and open competition for their business while minimizing risk, such as exposure to fraud and collusion.

Procurement categorisation and vendor management of indirect materials and services (commonly referred to as Indirect procurement) are typically the most popular outsourced activity.
