E-COMMERCE is an effort to describe business methodologies that address the needs of organizations, merchants, and consumers to cut costs while improving the quality of goods and services and increasing the speed of service delivery. By using Internet and understanding how Internet has blurred the line between e-commerce and traditional commerce, more businesses start and continue to integrate the Internet and e-commerce related technologies into their business processes leading to improved organizational performance. Adopting EDI, EPS, VPN and M-Commerce has lead to global market exposure, increasing profitability, gaining market share, improving customer service and faster delivery.
