Brick and mortar business
The term brick and mortar business (bricks and mortar business or B&M business) is often used to refer to a company that possesses a building or store for operations. The name is derived from the traditional building materials associated with physical buildings — bricks and mortar (the masonry that holds the bricks together). Its first use was in 1992.
More specifically, in the jargon of ecommerce businesses, brick and mortar businesses are companies that have a physical presence and offer face-to-face customer experiences. This term is usually used to contrast with a transitory business or an internet-only presence with no physical presence for shoppers to visit and buy from directly, though such online businesses normally have non-public physical facilities from which they either run business operations, and/or warehousing for mass physical product storage and distribution.
