practice
In some professions, a small business is called a practice rather than business, store, shop, etc. The term is often interchangeable with “office.” Practice is most commonly used by those who operate their own legal or medical business, such as a law practice or a chiropractic practice. Generally, only businesses of a smaller size refer to their business as a practice. For example, a law business that has many employees would most likely be called a firm, not a practice.
