A business (also known as enterprise or firm) is an organization engaged in the trade of goods, services, or both to consumers.[1] Businesses are predominant in capitalist economies, where most of them are privately owned and administered to earn profit to increase the wealth of their owners. Businesses may also be not-for-profit or state-owned. A business owned by multiple individuals may be referred to as a company, although that term also has a more precise meaning.

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 to mean a particular organization; the generalized usage to refer to a particular market sector, "the music business" and compound forms such as agribusiness; and the broadest meaning, which encompasses 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 and complexity of meanings.

A business opportunity (or bizopp) involves the sale or lease of any product, service, equipment, etc. that will enable the purchaser-licensee to begin a business. The licensor or seller of a business opportunity usually declares that it will secure or assist the buyer in finding a suitable location or provide the product to the purchaser-licensee. This is different from the sale of an independent business, in which there is no continued relationship required by the seller.
