Bills of exchange are similar to promissory notes; individuals or banks can draw them and are generally transferable by [endorsements](https://www.investopedia.com/terms/e/endorsement.asp).

## Using Bills of Exchange

A bill of exchange is [used in international trade](https://www.investopedia.com/ask/answers/040315/who-uses-bills-exchange.asp) to pay for goods or services. While a bill of exchange is not a contract, the involved parties can use it and its format to fulfill a contract. It can specify that payment is due on demand or at a specified future date. The period between billing and payment is [called the usance](https://www.investopedia.com/terms/u/usance.asp). It's often extended with credit terms, such as 90 days.

A transaction can involve up to three parties. The [drawee](https://www.investopedia.com/terms/d/drawee.asp) is the party that pays the sum specified by the bill of exchange. The payee is the one who receives that sum. The drawer is the party that obliges the drawee to pay the payee. The drawer and the payee are the same entity unless the drawer transfers the bill of exchange to a third-party payee.

Bills of exchange generally do not pay interest, making them, in essence, [post-dated checks](https://www.investopedia.com/terms/p/postdated.asp). They may accrue interest if not paid within an agreed timeline, and the rate must be specified on the instrument.

> A bill of exchange must be accepted by the drawee to be valid.

## Types of Bills of Exchange

*   **Bank Draft**: A bill of exchange issued by a bank. The issuing bank guarantees payment on the transaction.
*   **Trade Draft**: Bills of exchange issued by individuals.
*   **Sight Draft**: Funds are paid immediately or on demand. In international trade, a [sight draft](https://www.investopedia.com/terms/s/sight-draft.asp) allows an exporter to hold the title to the exported goods until the importer takes delivery and immediately pays for them.
*   **Time Draft**: Funds are paid at a set date in the future. A [time draft](https://www.investopedia.com/terms/t/time-draft.asp) gives the importer a short amount of time to pay the exporter for the goods after receiving them.

## Example

Suppose Company ABC purchases auto parts from Car Supply XYZ for $25,000. Car Supply XYZ draws a bill of exchange, becoming the drawer and payee in this case. The bill of exchange stipulates that Company ABC will pay Car Supply XYZ $25,000 in 90 days. Company ABC becomes the drawee and accepts the bill of exchange, and the goods are shipped.

In 90 days, Car Supply XYZ will present the bill of exchange to Company ABC for payment. The bill of exchange was an acknowledgment created by Car Supply XYZ, the creditor, to show the indebtedness of Company ABC, the debtor.

## What Are Some Differences Between a Bill of Exchange and a Check?

Checks are payable on demand, while a bill of exchange can specify that payment is due on demand or at a specified future date. Unlike a check, a bill of exchange is a written document outlining a debtor's indebtedness to a creditor.

## Why Are Bills of Exchange Useful in International Trade?

Bills of exchange are used in international trade because they help buyers and sellers deal with the risks associated with [exchange rate](https://www.investopedia.com/terms/e/exchangerate.asp) fluctuations and differences in legal jurisdictions.

## What's the Difference Between a Bill of Exchange and a Promissory Note?

The difference between a [promissory note and a bill of exchange](https://www.investopedia.com/ask/answers/042415/what-difference-between-bill-exchange-and-promissory-note.asp) is that the latter is transferable and can bind one party to pay a third party not involved in its creation. Banknotes are common forms of promissory notes. A bill of exchange is issued by the creditor who orders a debtor to pay a particular amount within a given period. A debtor issues a promissory note with a promise to repay money.

## The Bottom Line

Bills of exchange help facilitate the process of international trade by stipulating payment from one party to another at a specified date. They are not a contract but can be used to fulfill the terms of a contract.
