In the context of the music industry, a business manager is a representative of musicians and/or recording artists, whose main job is to supervise their business affairs, and the proper handling of their financial matters. The role as it is understood today was largely originated (and the term coined) by Allen Klein, who represented numerous performers through the years, helping them to both invest their incomes wisely and to recover unpaid (or underpaid) royalties and fees.
The Association of Professionals in Business Management (APBM) offers the Certified Business Manager (CBM) and Certified Associate Business Manager (CABM) designations.
Business Manager is also the name of a Windows based application used to monitor sales trends, forecast demand, monitor sales force activity etc. It was developed by Matt Akers for Coats plc
