Sourcing Finding suppliers, running bids, negotiating, and signing contracts. Stops at signature. The engine, not the car.
Procurement The full lifecycle: identifying needs → sourcing → buying → receiving → paying → managing suppliers → renewal or exit. The whole car.
RFP / RFQ Request for Proposal / Request for Quote — formal documents sent to suppliers asking them to bid on your work. Like sending out invitations and asking people to bring their best offer.
P2P (Procure-to-Pay) The process from raising a purchase order through receiving goods to paying the invoice. The "buying and paying" part that happens after the contract is signed.
Post-Award Everything after contract signature — compliance checks, supplier reviews, invoice matching. Where savings either land or leak. The marriage after the wedding.
Contract Compliance How often purchases actually use the negotiated contract instead of buying from elsewhere. If 40% of purchases skip your contract, 40% of your savings never happen.
