bill broker

A bill broker is primarily a British term for someone who negotiates the discount of bills of exchange. This involves either acting as an agent or directly buying and selling these bills. They might also buy bills and then carry them, using borrowed money as security.1

A bill of exchange is a short-term financial instrument, essentially a written order from a seller to a buyer, requiring payment of a specific sum of money at a future date or on demand to a named person or the bearer. These instruments originated in international trade as a way to settle accounts and became widely used by the 13th century.2
