Should Procurement Application Consumers Build or Buy?

This IDC Market Perspective explores the renewed build-or-buy debate for procurement applications in light of agentic AI and low-code platforms such as Claude Cowork, the Claude Cowork Legal Plug-in, OpenClaw, and Microsoft Power Apps with Copilot. It argues that although these tools make it easier to prototype and tailor procurement workflows, building is only the simplest step in a much larger journey. Operating a production-grade system still demands rigorous security, compliance, uptime, mobile-ready UX, and real-time support, all of which commercial suites have spent years hardening. The piece suggests a hybrid approach: buy a stable, well-governed platform for core records, workflows, and integrations, then selectively build on top where the organization's procurement processes are genuinely distinctive or fast-changing. Ultimately, the key question is not whether something can be built, but which parts of the lifecycle the organization is prepared to own versus delegate to a vendor."AI may make it easier to build procurement tools, but it does not make them easier to run; the real decision is which responsibilities you will own and which you will offload to a platform," says Patrick Reymann, research director, Procurement and Enterprise Applications, IDC.
