Whilst not bills of exchange, these are largely subject to the same rules and are used for a somewhat similar purpose, the settlement of indebtedness. Instead of being drawn like a bill of exchange by the person expecting to be paid, they are made by the person who owes the money, in favor of the beneficiary. A simple way of looking at a promissory note is to consider it an IOU. When due, it is presented for payment by the holder, who may be the payee or someone to whom the promissory note has been negotiated.
