Brick and mortar (also bricks and mortar or B&M) refers to a physical presence of an organization or business in a building or other structure. The term "brick-and-mortar business" is often used to refer to a company that possesses or leases retail shops, factory production facilities, or warehouses for its operations. More specifically, in the jargon of e-commerce businesses in the 2000s, brick-and-mortar businesses are companies that have a physical presence (e.g., a retail shop in a building) and offer face-to-face customer experiences.
