A business (also called a firm or an enterprise) is a legally recognized organization designed to provide goods and/or services to consumers, governments or other businesses. A business needs a market. A consumer is an essential part of a business.

Businesses are predominant in capitalist economies, most being privately owned and formed to earn profit to increase the wealth of owners. The owners and operators of a business have as one of their main objectives the receipt or generation of a financial return in exchange for work and acceptance of risk.

The etymology of "business" relates to the state of being busy either as an individual or society as a whole, doing commercially viable and profitable work.

The term "business" has at least three usages, depending on the scope — the singular usage (above) to mean a particular company or corporation, the generalized usage to refer to a particular market sector, such as "the music business" and compound forms such as agribusiness, or the broadest meaning to include all activity by the community of suppliers of goods and services. However, the exact definition of business, like much else in the philosophy of business, is a matter of debate.

Business Studies, the study of the management of individuals to maintain collective productivity in order to accomplish particular creative and productive goals (usually to generate profit), is taught as an academic subject in many schools.

Most commercial transactions are governed by a very detailed and well-established body of rules that have evolved over a very long period of time, it being the case that governing trade and commerce was a strong driving force in the creation of law and courts in Western civilization.

As for other laws that regulate or impact businesses, in many countries it is all but impossible to chronicle them all in a single reference source. There are laws governing treatment of labor and generally relations with employees, safety and protection issues (OSHA or Health and Safety), anti-discrimination laws (age, gender, disabilities, race, and in some jurisdictions, sexual orientation), minimum wage laws, union laws, workers compensation laws, and annual vacation or working hours time.

In some specialized businesses, there may also be licenses required, either due to special laws that govern entry into certain trades, occupations or professions, which may require special education, or by local governments who just want your money.

Professions that require special licenses run the gamut from law and medicine to flying airplanes to selling liquor to radio broadcasting to selling investment securities to selling used cars to roofing. Local jurisdictions may also require special licenses and taxes just to operate a business without regard to the type of business involved.

Some businesses are subject to ongoing special regulation. These industries include, for example, public utilities, investment securities, banking, insurance, broadcasting, aviation, and health care providers. Environmental regulations are also very complex and can impact many kinds of businesses in unexpected ways.
