C2B or Consumer- to- Business is a business model where the end consumers create products and services which are consumed by businesses and organizations. It is diametrically opposite to the popular concept of B2C or Business- to- Consumer where the companies make goods and services available to the end consumers.
In C2B, the companies typically pay for the product or service. However, it can assume different forms like an idea generated by an individual (like an innovative business practice) which may be used and implemented by an organization. Another possible form of C2B is where a consumer specifies a need and the various businesses compete or bid to fulfil that need.
