A signed paper that orders or promises payment of a fixed sum on a set date

A is a written order. The seller signs it and tells the buyer to pay a fixed sum of money. The money is due on demand or at a fixed or set future date. In trade, a bill of exchange is also called a draft (US International Trade Administration).

A is a written promise. Here the buyer signs it and promises to pay the seller a fixed sum, on the same kind of terms (UK Bills of Exchange Act 1882, section 83). US law uses the same split. A promise to pay is a note. An order to pay is a draft (US Uniform Commercial Code, section 3-104 (North Carolina text)).

Both must be unconditional. The paper says "pay this sum" with no "if" attached (UK Bills of Exchange Act 1882, section 3). Once the buyer accepts the bill, or signs the note, the seller holds a clear, signed promise to pay. The seller can keep it until the due date, pass it to someone else, or sell it for cash now.

Who is involved

  • The seller who writes and signs a bill is the .
  • The buyer the bill is addressed to, and who must pay, is the . Once the buyer signs to agree, the buyer is called the acceptor.
  • The buyer who signs a promissory note is the .
  • The payee is the person named to receive the money. The bill can also be made payable to whoever holds it.
  • The holder is the payee, or a later owner of the bill, who has the paper in hand (UK Bills of Exchange Act 1882, section 2).

For a promissory note, the buyer writes and signs the promise and gives it to the seller. There is no step 1 or step 3.

    What a bill or note means for each side

    Choose your side of the trade.

      Selling a $1 million bill 180 days early at an illustrative 5% a year brings in $975,000

      This example uses round, made-up numbers. The exporter holds a bill of exchange for $1,000,000, accepted by the buyer and due in 180 days. A finance provider buys it today. It takes its charge off the face value, a , at 5.00% a year on a 360-day year. The sum works the same way for a promissory note.

      A bill or note suits sellers who give credit and want a signed promise they can sell

      Good fit when

      Another tool may suit better when

      • You cannot meet the formal steps of the law that applies, such as an acceptance written on the bill and signed by the buyer. Look at open account.
      • You want a bank's promise to pay on a later date. Look at a usance letter of credit.
      • You need one international treaty to govern a paper bill across borders. The 1988 UN convention on international bills and notes has not entered into force (UNCITRAL), so check which national law applies.

      National laws set the rules for bills and notes, and an English court enforced two unpaid bills

      In the UK, the Bills of Exchange Act 1882 sets the rules (legislation.gov.uk). In the US, each state enacts Article 3 of the Uniform Commercial Code, a joint project of the Uniform Law Commission and the American Law Institute (ULC). A third system is the Geneva uniform law, signed on June 7, 1930 and in force since January 1, 1934 (UN Treaty Collection). The ICC rules for collections, , list bills of exchange and promissory notes as financial documents (ICC). When a bill or note is sold through forfaiting, the parties can use the ICC , in effect since January 1, 2013 (ICC).

      Bills and notes can also be electronic records. The UNCITRAL covers documents such as promissory notes (UNCITRAL). In the UK, the received royal assent on July 20, 2023 and came into force two months later (legislation.gov.uk).

      A real case. In GMAC Commercial Finance v Mint Apparel, decided on October 7, 2010, a trade finance provider paid exporters 80% of each invoice. It then drew a bill of exchange on the importer for 100% of the invoice value. Two accepted bills, for $671,826.21 and $87,374.28, fell due on February 23 and March 23, 2010, and were not paid. The claim was for US$759,200.49 plus interest. The High Court in London said that bills of exchange are generally treated as cash, and gave judgment for GMAC, the finance company that brought the claim, without a full trial (High Court judgment).

      A bill or note turns the buyer's debt into a signed paper the seller can hold or sell

      The seller gets the buyer's signed promise to pay a fixed sum on a set date. The buyer gets time to pay. The seller can wait for the due date or sell the paper for cash now. Get the paper right: no conditions, a fixed sum, a clear date and a signed acceptance.
