B2B e-commerce refers to business transactions conducted electronically over the Internet. It allows businesses to buy, sell, partner and trade with other businesses more efficiently. B2B service providers help businesses improve operations like supply chain management and logistics through e-commerce solutions. While many B2B e-commerce companies failed during the dot-com bubble of the late 1990s, those that survived have seen soaring revenues as B2B e-commerce has grown at an annual rate of 16% and become the fastest growing form of retail trade.
