1:30 PM Panel: The Media Reconciliation Crisis: Can Procurement Fix It?
Why do media spend and delivery data so often fail to match—and what can procurement do now that AI auditing tools are finally affordable and accessible? As media prices shift and assets underdeliver, traditional MMM assumptions break down and procurement is left manually reconciling what was planned, bought, and actually delivered. AI‑powered reconciliation systems are changing this equation, dramatically reducing audit effort and enabling a "clear box" view of media performance and value.
- Diagnose the root causes of misalignment between planned, purchased, and delivered media
- Leverage AI‑driven tools to automate reconciliation and reduce auditing costs
- Elevate procurement's role by turning reconciled data into strategic guidance for marketing and finance
