A money services business (MSB) is a legal term used by financial regulators to describe businesses that transmit or convert money. The definition was created to encompass more than just banks which normally provide these services to include non-bank financial institutions. An MSB often provides an essential financial service to underdeveloped regions with limited or no banking services and may be a small organisation with outlets like grocery stores, drugstores, pharmacies or convenience stores. It may include regional networks of post offices, banks or agents.
