"C to C" refers to a type of business model in which companies or individuals sell products or services directly to other companies or individuals. This model is also commonly known as "business-to-business" or "B2B." There are a number of synonyms that may be used to describe this type of commerce, including "trade," "commerce," "transactions," and "dealings." Other terms that may be used include "wholesale," "distribution," "supply chain," and "procurement." While these terms all refer to slightly different aspects of the C-to-C business model, they are all useful in describing the process of businesses selling goods and services to one another.
