The goal of e-procurement is to ensure the availability of relevant goods in a company, services, and other resources. A distinction is made between the strategic goals, which include quality and supply assurance, and the operational goals such as reduction of storage costs and optimization of the costs of activities in the ordering process. Despite the complexity and potential of E-procurement, support by artificial intelligence (AI) is still not widespread. To capture the current state of research and its use in practice, a systematic literature review on the use of AI in e-procurement is conducted in this paper.
