A letter of credit is a promise from a bank to pay a seller on behalf of a buyer, as long as the seller shows the right documents. It's widely used in international trade, where buyer and seller may not know or trust each other.

How it works

  • The buyer asks their bank to issue a letter of credit in the seller's favour.
  • The seller ships the goods and gathers the documents the letter asks for, such as the bill of lading and invoice.
  • The banks check the documents match the terms exactly.
  • If they match, the bank pays the seller and the buyer's account is charged.

Why businesses use them

The seller knows a bank will pay if they meet the terms, and the buyer knows payment only goes out once proof of shipment arrives. That trust makes it easier to trade with new partners abroad.

The downsides

Banks charge fees to issue and check letters of credit, and small mistakes in the documents can delay payment. For smaller or repeat orders, many businesses use simpler options such as a deposit plus a bank transfer on delivery.
