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.

Notable exceptions include cooperative businesses and state-owned enterprises. Socialist systems involve either government agencies, public, or worker ownership of most sizable businesses.

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.

Many businesses are operated through a separate entity such as a corporation, limited partnership or limited liability company. Most legal jurisdictions allow people to organize such an entity by filing certain charter documents with the relevant Secretary of State or equivalent and complying with certain other ongoing obligations.

The relationships and legal rights of shareholders, limited partners, or members are governed partly by the charter documents and partly by the law of the jurisdiction where the entity is organized. Generally speaking, shareholders in a corporation, limited partners in a limited partnership, and members in a limited liability company are shielded from personal liability for the debts and obligations of the entity, which is legally treated as a separate "person." This means that unless there is misconduct, the owner's own possessions are strongly protected in law, if the business does not succeed.

Where two or more individuals own a business together but have failed to organize a more specialized form of vehicle, they will be treated as a general partnership. The terms of a partnership are partly governed by a partnership agreement if one is created, and partly by the law of the jurisdiction where the partnership is located.

No paperwork or filing is necessary to create a partnership, and without an agreement, the relationships and legal rights of the partners will be entirely governed by the law of the jurisdiction where the partnership is located.
