Business-to-government e-commerce or B2G is generally defined as commerce be-

procurement, licensing procedures, and other government-related operations. This kind
of e-commerce has two features: first, the public sector assumes a pilot/leading role in
establishing e-commerce; and second, it is assumed that the public sector has the
greatest need for making its procurement system more effective.
