Business-to-business (B2B) is a business sales model that describes exchanges of goods or services between two or more businesses. Although B2B is used in many industries and by many companies offering different products or services, it is primarily seen in the market of raw material exchange. B2B is also seen heavily in all facets of manufacturing industries.
Many companies that maintain B2B interactions also have sectors that are purely B2C (Business-to-Consumer), such as Wells Fargo, HSBC, or General Electric. Though these companies offer services to consumers like bank accounts or appliances, the larger portion of their business model is providing directly to other businesses. Wells Fargo, for example, provides mass-scale business banking and loans but also provides personal banking. General Electric does manufacture and distribute appliances direct to consumers, but on a larger scale, they send the appliances to third-party retailers to then be purchased by consumers.
