The current literature on AI in procurement is growing, but only a small portion of this literature is focused on Agentic AI systems, which are characterized by autonomy, goal-directed behaviour, and decision-making capacity. This book explores how autonomous agents reshape sourcing, negotiation, compliance, and supplier interaction, while addressing risks, governance, and organizational change. Positioned at the intersection of AI innovation and procurement strategy, this book constitutes the first exclusive resource on the transformative potential of Agentic AI on procurement. It will be of great interest to researchers and students of operations management and technological innovation strategy, as well as policymakers and industry professionals seeking to understand and leverage agentic AI as a transformative force in procurement.
