SaaS Spend Management platforms discover, track, and optimize software subscriptions across the organization — identifying redundant tools, unused licenses, shadow IT, and renewal opportunities that procurement and IT teams can act on. Core capabilities include SaaS application discovery (through SSO, expense, and browser data), license utilization tracking, spend normalization and benchmarking, renewal calendar management, contract and vendor consolidation recommendations, and integration with SSO, HRIS, expense management, and procurement systems. The category spans dedicated SaaS management platforms (Zylo, Productiv, Torii, Zluri) and SaaS optimization features within broader IT asset management suites.
