Firm
It is a business organization that owns, rents, and operates equipment, hires labor and buys materials and energy inputs. The firm organizes and coordinates the use of all these factors of production to produce and market goods and services [Н. Краус, К. Краус, p.219].
A firm is a for-profit business organization—such as a corporation, limited liability company (LLC), or partnership—that provides professional services. Most firms have just one location. However, a business firm consists of one or more physical establishments, which all fall under the same ownership and use the same employer identification number (EIN).
When used in a title, "firm" is typically associated with businesses that provide professional law and accounting services, but the term may be used for a wide variety of businesses, including finance, consulting, marketing, and graphic design firms, among others. A firm typically excludes the sole proprietorship business; it generally refers to a for-profit business managed by two or more partners providing professional services, such as a law firm. In some cases, a firm can be a corporation [Investopedia].
