Bricks and mortar (also B&M) in its simplest usage describes the physical presence of a building/s or other structure. In the jargon of e-commerce 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, such as an online shop, which have 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.
