While business-to-business commerce refers to business transactions between companies, business-to-consumer models are those that sell products or services directly to personal-use customers. B2C or business-to-consumer companies connect, communicate and conduct business transactions with consumers most often by means of the Internet.
B2C is larger than just online retailing and includes
- online banking,
- travel services,
- online auctions, and
- health and real estate sites.
