Procurement is how organizations source and buy the goods and services they need to operate. This guide covers the procurement process, its types, and the contracts involved.

Procurement is the end-to-end process organizations use to source, evaluate, purchase, and pay for the goods and services they need to operate. It covers everything from identifying a need and selecting a supplier to negotiating a contract and managing the relationship over time.
Quick answer: procurement is not just "buying." Buying is the single transaction; procurement is the full strategic process around it, including sourcing, supplier evaluation, negotiation, contracting, and ongoing management.
The two terms are often used interchangeably, but they are not the same. Purchasing is the transactional act of ordering and paying for something. Procurement is the broader, strategic function that surrounds purchasing: deciding what to buy, choosing suppliers, controlling cost and risk, and managing contracts. Purchasing is one step inside procurement.
Most procurement follows a repeatable cycle. The exact number of steps varies by organization, but the core stages are consistent:

Procurement is usually grouped into a few categories:
Contracts are where procurement becomes binding. A procurement contract sets out what each party will deliver, at what price, and under what terms. Common agreements you will encounter include:
A purchase order also raises a common question: is it a contract on its own? We answer that in detail in is a purchase order a contract? Procurement contracts are simply one category in the wider world of business agreements; see our guide to types of contracts for the full picture.
Sourcing and signing are only the beginning. The real challenge is managing dozens or hundreds of active supplier contracts, each with its own renewal dates, pricing terms, and obligations. When those terms live as plain text scattered across separate files, a single change, such as a renegotiated rate or a renamed entity, has to be hunted down everywhere, and details slip through the cracks.
Treating contracts as structured, connected data rather than static documents solves this. Update a defined term once and every reference updates with it, so the system always reflects the current agreement. That shift, from documents to a system of record, is why defined terms break at scale in traditional tools, and it is increasingly central to modern contract lifecycle management in procurement.
