There are many types of e-commerce, but perhaps the most common is business to business (B2B) e-commerce. This type of transaction is when both parties involved are businesses. Not all consumers are familiar with this type of e-commerce, though, since most of their own transactions would be classified as business-to-consumer (B2C) e-commerce.
Business-to-consumer (B2C) is an Internet and electronic commerce (e-commerce) model that denotes a financial transaction or online sale between a business and consumer. B2C involves a service or product exchange from a business to a consumer, whereby merchants sell products to consumers.
On the Internet, B2G is business-to-government (a variation of the term B2B or business-to-business), the concept that businesses and government agencies can use central Web sites to exchange information and do business with each other more efficiently than they usually can off the Web.
This part of e-commerce encompasses all transactions conducted online between companies and public administration. This is an area that involves a large amount and a variety of services, particularly in areas such as fiscal, social security, employment, legal documents and registers, etc.
What Is Consumer-to-Consumer E-Commerce? Have you ever bought or sold an item on eBay.com or craigslist.org? If so, you have participated in consumer-to-consumer (C2C) e-commerce. People who come together to buy, sell or trade items online take part in C2C e-commerce.
G2C (Government to Citizen) is a term that refers to the relationships between organizations (subjects) of public administration and a citizen(s). The designation can be used for any relationship between the subject of public administration and the citizen, most often it is used as one of the basic relationship within e-Government models.
