Business-to-business (B2B or, in some countries, BtoB) refers to a situation where one business makes a commercial transaction with another. This typically occurs when:
B2B is often contrasted with "business-to-consumer (B2C). In B2B commerce, it is often the case that the parties to the relationship have comparable "negotiating power, and even when they do not, each party typically involves professional staff and legal counsel in the negotiation of terms, whereas B2C is shaped to a far greater degree by economic implications of "information asymmetry. However, within a B2B context, large companies may have many commercial, resource and information advantages over smaller businesses. The United Kingdom government, for example, created the post of "Small Business Commissioner under the Enterprise Act 2016 to "enable small businesses to resolve disputes" and "consider complaints by small business suppliers about "payment issues with larger businesses that they supply".
In most cases, the overall volume of B2B (business-to-business) transactions is much higher than the volume of B2C transactions. The primary reason for this is that in a typical "supply chain there will be many B2B transactions involving subcomponents or "raw materials, and only one B2C transaction, specifically sale of the finished product to the end customer. For example, an automobile manufacturer makes several B2B transactions such as buying tires, glass for windscreens, and rubber hoses for its vehicles. The final transaction, a finished vehicle sold to the consumer, is a single ("B2C) transaction.
