Source-to-Contract (S2C) platforms manage the upstream procurement cycle — supplier identification, competitive sourcing events, negotiation, and contract execution — to ensure Procurement secures the best terms before operational purchasing begins. Core capabilities include supplier discovery and qualification, RFx creation and management (RFP, RFQ, RFI), reverse auctions, bid analysis and award recommendation, contract authoring and negotiation, savings tracking, and integration with supplier databases, CLM, and S2P systems. The category spans dedicated S2C platforms (Scout RFP/WorkDay, Market Dojo, Keelvar) and sourcing modules within broader S2P suites (Coupa, Jaggaer, GEP).
