A letter of credit is a document from a bank guaranteeing that a seller will receive payment in full as long as certain delivery conditions have been met. In the event that the buyer is unable to make payment on the purchase, the bank will cover the outstanding amount. They are often used in international transactions to ensure that payment will be received where the buyer and seller may not know each other and are operating in different countries. In this case the seller is exposed to a number of risks such credit risk, and legal risk caused by the distance, differing laws and difficulty in knowing each party personally. A letter of credit provides the seller with a guarantee that they will get paid as long as certain delivery conditions have been met. For this reason the use of letters of credit has become a very important aspect of international trade.

The bank that writes the letter of credit will act on behalf of the buyer and make sure that all delivery conditions have been met before making the payment to the seller. Most letters of credit are governed by rules promulgated by the International Chamber of Commerce known as Uniform Customs and Practice for Documentary Credits. Letters of credit are typically used by importing and exporting companies particularly for large purchases and will often negate the need by the buyer to pay a deposit before delivery is made.
