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.

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, facilitating market entry into new countries and supporting global sourcing strategies.

  • 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 supplier bases and markets through increased transaction security.

    Letter of credit business: from traditional documents to digital solutions

    Building on the theoretical basis of the documentary credit business, this instrument continues to be an essential component of international trade. In practice, the letter of credit provides security and trust between buyers and sellers, especially in cross-border transactions. However, traditional processes often lead to delays and increased administrative effort. Advancing digitalization has therefore highlighted the need for more efficient solutions to make trade faster and more secure.

    Old: Classic documentary letter of credit

    Traditional approach: With traditional documentary letters of credit, orders are processed using physical paper documents. After shipping the goods, the seller submits the required documents such as commercial invoices, bills of lading and proof of insurance to their bank. These documents are checked manually and forwarded to the buyer via correspondent banks. The entire process is time-consuming and prone to errors. Typical challenges include postal delays, loss of documents and inconsistencies in paperwork that can lead to non-payment or risk management.

    New: Electronic letter of credit

    Electronic Letters of Credit: Modern approaches use digital platforms to process documentary credit transactions. Switching to electronic documents and digital signatures speeds up the process considerably. Documents are exchanged in real time over secure networks and automated systems check compliance with the terms of the letter of credit. These innovations reduce the risk of errors and eliminate delays caused by the physical transfer of documents. They also increase the supply chain visibility and traceability of every transaction, boosting the confidence of all parties involved.

    Practical example: Digitalization at TradeSecure GmbH

    TradeSecure GmbH, a German import-export company, implemented an electronic letter of credit system to optimize its international trade. Following the introduction of the digital solution, the processing time per transaction was reduced from an average of ten days to two days. The electronic verification of documents led to a 70% reduction in errors. Communication costs were also reduced by 40%. These efficiency gains enabled TradeSecure GmbH to increase its turnover by 15% within a year and open up new markets in Asia and Africa.

    Conclusion on the letter of credit business

    The letter of credit business is an indispensable instrument in international trade that offers decisive advantages despite higher costs and administrative effort. It minimizes risks for all parties involved, creates trust between unknown trading partners and enables secure global business relationships. With increasing digitalization, the letter of credit business is becoming more efficient and user-friendly, but its basic function as a hedging instrument remains important for international trade.
