Source-to-Pay (S2P) suites unify the full procurement lifecycle — from strategic sourcing and supplier selection through contracting, purchasing, invoicing, and payment — in a single platform. Core capabilities span sourcing event management (RFx, auctions), supplier qualification and onboarding, contract authoring and storage, catalog management, purchase requisition and approval, invoice processing and matching, and spend analytics across the entire cycle. The category represents the broadest procurement platform play, combining Source-to-Contract and Procure-to-Pay into one system. It spans enterprise S2P suites (Coupa, SAP Ariba, Jaggaer, GEP SMART, Ivalua) that serve large organizations with complex, multi-category procurement operations.
