Book of business is a professional American term — common in law, insurance, finance, and consulting — referring to the portfolio of clients or accounts a professional manages.

Origin: 'Book' in the sense of a record or register of accounts, combined with 'business' (clients, commerce); analogous to a bookmaker's book. Editorial expansion authored on Slangora.
