E-procurement refers to the electronic acquisition of goods and services for organizations using the internet. It involves the transactional aspects of requisitioning, authorizing, ordering, receipting and payment processes. Main types of e-procurement include e-sourcing, e-tendering, e-informing, and web-based ERP systems. E-procurement provides benefits such as cost savings, control over maverick spending, improved information flow between buyers and suppliers, and increased buying power. However, concerns include security risks with new systems, transition costs, compatibility with supplier technologies, and ensuring employee skills.
