Letter of credit business: definition & important aspects for buyers

The documentary credit business creates security in international trade and enables companies to successfully process transactions even with unknown business partners. This structured overview shows the most important aspects of documentary letters of credit and how purchasing departments can use this instrument to minimize risk and build trust.

Letter of credit business in a nutshell:

A letter of credit is an irrevocable promise of payment by a bank, whereby the bank undertakes to pay the agreed purchase price to the seller on presentation of certain documents. For the buyer, it offers maximum payment security for international transactions and minimizes risks, as payment is only made once the correct documents have been presented.

Example: A German company imports machinery worth EUR 250,000 from China and opens a letter of credit via its house bank that guarantees payment to the Chinese supplier within 30 days of presentation of the agreed shipping documents.

Introduction to the letter of credit business

Letters of credit are an important instrument in international trade and foreign trade financing. It is a documentary form of payment in which a bank assumes the obligation on behalf of the importer to pay the exporter a certain amount against presentation of contractually agreed documents. This payment method offers both trading partners a high degree of security: the exporter receives a payment guarantee from a bank, while the importer can ensure that payment is only made after proper documentation has been submitted. This introduction takes a closer look at the basic aspects of the letter of credit business, how it works and the various types and advantages of this trade financing method.

What is a letter of credit transaction?

A letter of credit is an internationally recognized instrument for securing payments and deliveries in foreign trade. The importer's bank (issuing bank) promises to make a payment to the exporter (beneficiary) as soon as the exporter presents the documents specified in the letter of credit. This procedure minimizes risks such as non-payment or non-delivery and creates trust between business partners who may not know each other personally.

Core elements of the letter of credit business

  • Opening of the letter of credit: The buyer instructs his bank to open a letter of credit in favor of the seller.
  • Documentary letter of credit: Payment is made against presentation of specified commercial documents such as bills of lading, invoices or certificates of origin.
  • Bank commitment: The bank guarantees payment if the conditions are met, regardless of the buyer's creditworthiness.
  • International guidelines: Processing according to the "Uniform Customs and Practice for Documentary Credits" (UCP 600) of the International Chamber of Commerce.
  • Significance for purchasing

    In the procurement process of international companies, the letter of credit business plays a decisive role in securing supply chains and payment flows. It enables buyers to source goods from unknown or new suppliers without taking the full risk of prepayment. By involving banks, trust is strengthened, which facilitates market entry into new countries and supports the global procurement strategy.

  • Risk management: Minimization of financial risks in international transactions.
  • Liquidity optimization: Flexible payment terms protect your own financial resources.
  • Market development: Secure access to new suppliers and markets through increased transaction security.

    Application of the letter of credit transaction in practice

    The letter of credit transaction is used to secure international payments by involving a bank as a guarantor. The buyer initiates a letter of credit in favor of the seller, which guarantees payment as soon as the agreed documents are presented.

    Practical example

    Situation: A German company orders electronic components worth 50,000 euros from a new supplier in Taiwan:
    • Opening of the letter of credit: The German buyer instructs his bank to open an irrevocable documentary letter of credit in favor of the Taiwanese seller.
    • Specification of documents: The conditions agreed are the submission of a commercial invoice, packing list and a shipping document (bill of lading).
    • Shipping the goods: The seller ships the components and receives the necessary documents from the shipping company.
    • Document submission: The seller submits the documents to his bank, which forwards them to the buyer's bank.
    • Verification and payment: The buyer's bank checks the documents for compliance with the terms and conditions of the letter of credit. If the result is positive, payment is made to the seller.

    Benefit: Both parties minimize their risk: the buyer only pays upon proof of shipment, the seller receives a payment commitment from a reputable bank.
