What is business-to-business (B2B) e-marketing? What are its features? What are the tools that are associated with the functions of B2B e-marketing?

Business-to-business (B2B) e-marketing is the use of the Internet for business transactions between organizations.
In addition to generating sales revenue, B2B e-marketing also provides detailed product descriptions whenever needed. Payments and other information are exchanged on the Web, and B2B e-marketing can slash order-processing expenses. Business-to-business transactions, which typically involve more steps than consumer purchases, can be much more efficient on the Internet. Orders placed over the Internet usually contain fewer errors than handwritten ones, and when mistakes occur, the technology can quickly locate them. This makes the Internet an attractive option for business buying and selling.
B2B e-marketing activity has become more varied in recent years. In addition to using the Web to conduct individual sales transactions and provide product information, companies use such tools as EDI, Web services, extranets, private exchanges, electronic exchanges, and e-procurement.
