Commerce refers to the buying and selling of goods and services for money or in kind. It is a branch of business that focuses on the distribution side of the business, rather than production. Commerce includes all the processes related to the exchange of goods and services, and it generates a profit for one of the parties involved. Commerce can take place between businesses, between consumers, or between businesses and consumers. It involves the exchange of value and often generates a profit for one of the parties involved. Commerce is not synonymous with business but is a subset of it. Commerce does not relate to the sourcing, manufacturing, or production processes but only to the distribution of goods and services. There are two branches of commerce: trade and aids to trade. Trade can be either internal (within a countrys borders) or external (between countries). Aids to trade include transport, warehousing, distribution, advertising, insurance, and banking. There are seven primary commerce business models: B2C, B2B, B2A, C2A, C2C, C2B, and DTC. Commerce is important for maintaining the flow of commercial goods and products in and out of a country. It regulates the supply and demand of a product or an industry. Commerce is what links producers to traders and consumers. It also ensures the proper living standards of citizens of a country.
