The Post-S2P Era Will Be Here Sooner Than You Think - What Will Replace It?

This IDC Market Perspective argues that monolithic S2P suites are giving way to an Intelligent Spend OS: an agent-native, composable layer that orchestrates existing tools, unifies stakeholder engagement, and governs AI agents across the spend life cycle. Orchestration and headless agentic platforms are already inserting themselves between buyers and suites, so incumbents must pivot to data-centric, governed, and open platforms with ISOS-aligned pricing to avoid commoditization."In the post-S2P era, will your procurement platform orchestrate intelligence and adapt, or become invisible behind agent-native layers? The race is not for another suite but for the operating system that governs enterprise spend." - Patrick Reymann, research director, director, Procurement Applications and Agents, IDC.
