Procurement is the work of buying for a company: finding suppliers, agreeing prices, raising orders and paying invoices. It is also called purchasing. A large company often spends more with its suppliers than on its own staff. So saving even two or three per cent of that spending is worth a great deal.
Take, for example, a bicycle maker in Ludhiana that buys steel tubes, tyres, chains and saddles from 80 suppliers. To buy tyres, the purchasing team first asks several suppliers for prices and chooses one. This first stage is called strategic sourcing. The team then signs a contract with the chosen supplier, raises a purchase order, receives the tyres and pays the invoice. Procure-to-pay software runs this whole chain in one product. The industry calls the full chain source-to-pay, and the part from the order to the payment procure-to-pay.
The company also pays for things that nobody counts each month. It pays for 400 mobile connections for its sales staff, internet lines at three factories and many software subscriptions. Telecom and technology expense management checks these bills. It finds lines that nobody uses, and services that the company pays for twice. Software licences and subscriptions have their own tools: software asset management (SAM) and SaaS management.
The order is raised in this zone, but the money is paid out elsewhere. Accounts payable (AP) automation checks each invoice and pays it. Later, financial close software checks the payment against the books.
Two changes are under way. Some suppliers are now chosen by an AI agent that collects quotes and negotiates routine purchases, while a buyer approves the result. The page on agentic commerce explains the idea. And some companies hand the buying itself to an outside firm, whose own staff do the purchasing for them. This is a kind of managed service.
