eSourcing platforms manage competitive bidding events — RFPs, RFQs, RFIs, and reverse auctions — enabling Procurement to evaluate supplier proposals, compare pricing, and award business based on structured criteria. Core capabilities include sourcing event creation and template management, supplier invitation and response collection, bid comparison and scoring matrices, reverse auction facilitation, award scenario analysis, and integration with supplier databases and contract management systems. The category spans dedicated eSourcing tools (Keelvar, Market Dojo, Scanmarket) and sourcing modules within broader procurement suites.
