Electronic procurement (e-procurement) is one business-to-government e-commerce venture that can benefit from the Internet. Government e-procurement is different from private sector e-procurement because of concepts such as value for money, transparency and accountability, which may be considered the main benefits for the public sector. Public sector organizations have to meet multiple, often conflicting goals, and they are subject to constraints of a financial, legal, contractual, personnel and institutional nature. In addition, radical process changes from e-procurement can only be achieved with deep changes in bureaucratic practices. These changes cannot normally be achieved without either changes in the law or privatization (Panayiotou, Gayialis, & Tatsiopoulos, 2004).
