In our 28-criteria evaluation of contract life-cycle management (CLM) software providers, we identified the 14 most significant vendors — Apttus, CLM Matrix, CobbleStone Systems, Determine, Exari Systems, GEP, IBM Emptoris, Icertis, Oracle, Revitas, SAP Ariba, SciQuest, Symfact, and Zycus — and researched, analyzed, and scored them. This report shows how each provider measures up, and it helps CIOs make the right choice from three dimensions: buy-side dominant, sell-side dominant, and all contract life-cycle management.
