Profit statement (P&L) The financial report that shows whether the company made or lost money in a period. Where savings must appear to count.
Off-contract buying Buying from suppliers outside of negotiated contracts — like shopping at a convenience store when you have a Costco membership.
ERP / Accounting system The company's main financial system that tracks money in and out. Sees totals, not contract details.
Buying system (P2P) Procure-to-Pay — the system that handles purchase orders, receiving, and invoice payment. Where the gap lives.
Category strategy A plan for how to buy a group of related products or services — which suppliers, what terms, how to monitor compliance.
Realized savings Savings confirmed by actual invoice data — not the estimate from the RFP, not the number in the contract. What actually landed.
