C2B (Consumer to Business)
It is a process of selling and buying product between consumer and company. Consumer-to-business (C2B) is an electronic commerce business model in which consumers (individuals) offer products and services to companies and the companies pay them. This business model is a complete reversal of traditional business model where companies offer goods and services to consumers (business-to-consumer = B2C).
Example of C2B
