A letter of credit is a financial document issued by a bank that guarantees a seller will be paid as long as they meet specific conditions outlined in the credit agreement. In international trade, where buyers and sellers may be located in different countries, a letter of credit helps reduce risk by ensuring that payment is made when the seller provides the required documents proving that goods or services have been delivered or prepared for shipment. It is one of the most widely used payment methods in global commerce because it creates trust between parties who may not know each other well The details matter here..
Introduction to What Is a Letter of Credit?
A letter of credit, often abbreviated as LC, is a promise from a bank to pay a seller, also called the beneficiary, on behalf of the buyer, known as the applicant. The bank agrees to make payment only if the seller submits documents that strictly comply with the terms of the letter of credit Worth keeping that in mind..
This payment method is especially important in international trade, where sellers may worry that the buyer will not pay after shipment, while buyers may worry that they will pay before receiving goods. Think about it: a letter of credit balances these concerns by involving banks as trusted intermediaries. Instead of relying only on the buyer’s promise to pay, the seller receives a bank’s guarantee, subject to the documents being in order.
How a Letter of Credit Works
A letter of credit works by setting clear conditions that must be met before payment is released. These conditions usually include documents such as:
- Commercial invoice
- Bill of lading or shipping document
- Packing list
- Certificate of origin
- Insurance certificate
- Inspection certificate
- Customs documents
The seller must present these documents to the bank within the required time frame. Plus, if the documents match the terms of the letter of credit exactly, the bank must honor the payment. If the documents contain errors or do not meet the stated requirements, the bank may refuse payment or request corrections.
This document-based nature is one of the most important features of a letter of credit. Day to day, banks deal with documents, not with the actual goods themselves. If the documents prove that the seller fulfilled the agreed requirements, the bank pays. If the goods are damaged, late, or different from what was expected, that issue is usually handled separately through contracts, insurance, or legal remedies unless the documents themselves show non-compliance Most people skip this — try not to..
Main Parties Involved in a Letter of Credit
Understanding the parties involved helps explain why a letter of credit is useful in trade transactions.
1. Applicant
The applicant is usually the buyer or importer. Now, this party requests the bank to issue the letter of credit in favor of the seller. The applicant is responsible for providing the correct information and funds or credit approval to the issuing bank.
2. Beneficiary
The beneficiary is usually the seller or exporter. This party receives the benefit of the letter of credit and must comply with its terms to receive payment Simple, but easy to overlook..
3. Issuing Bank
The issuing bank is the buyer’s bank. It issues the letter of credit and takes on the obligation to pay the beneficiary if the required documents are presented correctly Nothing fancy..
4. Advising Bank
The advising bank is usually located in the seller’s country. In real terms, its role is to confirm to the seller that the letter of credit is genuine and to transmit it to the beneficiary. The advising bank does not always guarantee payment unless it adds its own confirmation Simple as that..
5. Confirming Bank
A confirming bank adds its own payment guarantee to the letter of credit. Simply put, even if the issuing bank fails to pay, the confirming bank is still obligated to pay if the documents comply. This is especially useful when the seller does not know the issuing bank or is concerned about political, currency, or banking risks in the buyer’s country.
6. Negotiating Bank
The negotiating bank reviews and may purchase or advance payment against the documents presented by the seller. This can help the seller receive funds faster instead of waiting until the buyer’s bank completes its review.
Common Types of Letters of Credit
There are several types of letters of credit, each designed for different trade situations.
Irrevocable Letter of Credit
An irrevocable letter of credit cannot be changed or canceled without the consent of all major parties involved, including the seller, buyer, and banks. Most international trade transactions use irrevocable letters of credit because they provide stronger security for the seller.
Revocable Letter of Credit
A revocable letter of credit can be modified or canceled by the buyer or issuing bank without prior notice to the seller. Because this type offers little protection to the seller, it is rarely used in international trade.
Confirmed Letter of Credit
A confirmed letter of credit includes a guarantee from an additional bank, known as the confirming bank. This gives the seller a stronger payment assurance, especially when dealing with unfamiliar foreign buyers or unstable financial environments Small thing, real impact..
Unconfirmed Letter of Credit
An unconfirmed letter of credit relies only on the issuing bank’s promise to pay. The seller accepts the credit risk of the issuing bank and the country where that bank operates Small thing, real impact..
Sight Letter of Credit
A sight letter of credit requires payment to be made when the seller presents compliant documents. Payment is immediate or due shortly after document review Worth knowing..
Usance Letter of Credit
A usance letter of credit, also called a deferred payment letter of credit, allows payment at a future date, such as 30, 60, or 90 days after documents are presented. This gives the buyer time to sell the goods or arrange financing before paying.
Standby Letter of Credit
A standby letter of credit is more like a backup guarantee. It is used to ensure payment or performance if one party fails to meet an obligation. Unlike a commercial letter of credit, which is meant to be used when goods or services are delivered, a standby letter of credit is usually drawn upon only if something goes wrong The details matter here. But it adds up..
Transferable Letter of Credit
A transferable letter of credit allows the original beneficiary, often a middleman or trader, to transfer all or part of the credit to another supplier. This is common when a trader arranges a sale but the actual goods are shipped by a manufacturer That's the part that actually makes a difference..
Revolving Letter of Credit
A revolving letter of credit can be used multiple times up to a certain limit and time period. This is useful for repeated shipments between the same buyer and seller, as it reduces the need to issue a new letter of credit for every transaction Still holds up..
Not the most exciting part, but easily the most useful And that's really what it comes down to..
Step-by-Step Process of a Letter of Credit
The letter of credit process usually follows several steps.
1. Sales Contract Is Agreed
The buyer and seller first agree on the terms of the trade transaction. These terms may include price, quantity, delivery schedule, shipping method, payment method, and required documents Easy to understand, harder to ignore..
2. Buyer Requests the Letter of Credit
The buyer asks its bank, the issuing bank, to issue a letter of credit in favor of the seller
3. Issuing Bank Issues the Letter of Credit
Upon the buyer’s request, the issuing bank drafts the letter of credit according to the agreed sales contract terms. It specifies the amount, expiry date, required documents (such as commercial invoice, packing list, bill of lading, certificate of origin, and inspection certificate), and any special conditions. The bank then transmits the LC—usually via SWIFT or a secure electronic platform—to the advising bank nominated by the seller.
4. Advising Bank Notifies the Seller
The advising bank verifies the authenticity of the LC, often by checking signatures and test keys, and forwards it to the seller (the beneficiary). At this stage the seller examines the credit to see to it that the terms match the contract and that the documentary requirements are practicable. If any clause appears problematic, the seller may request amendments through the buyer before proceeding It's one of those things that adds up. And it works..
5. Seller Ships the Goods and Prepares Documents
After confirming that the LC is acceptable, the seller arranges production, packaging, and shipment in accordance with the contract. Simultaneously, the seller prepares the stipulated documents. Accuracy is crucial: each document must conform exactly to the LC’s description, otherwise the bank may refuse payment on grounds of discrepancy.
6. Presentation of Documents to the Negotiating/Advising Bank
The seller presents the complete set of documents to the advising bank (which may also act as a negotiating bank). The bank checks the documents for compliance with the LC’s terms. If everything is in order, the bank may either:
- Negotiate – advance funds to the seller immediately (often at a discount) and then seek reimbursement from the issuing bank; or
- Forward – send the documents to the issuing bank for examination without providing immediate funds.
7. Examination by the Issuing Bank
The issuing bank scrutinizes the documents against the LC. If they find no discrepancies, they honor their undertaking by reimbursing the negotiating bank (or paying the seller directly if no negotiation occurred). Should discrepancies arise, the issuing bank notifies the seller and gives them an opportunity to correct the documents or obtain a waiver from the buyer. Only after the discrepancies are resolved—or a waiver is granted—does payment proceed.
8. Payment to the Seller
Once the issuing bank confirms compliance, it transfers the agreed amount to the negotiating bank, which in turn credits the seller’s account. In a sight LC, this happens promptly after document verification; in a usance LC, the bank records a maturity date and pays the seller on that future date, often after accepting a time draft or promissory note That alone is useful..
9. Buyer Receives Documents and Clears Goods
After payment (or acceptance of a time draft), the issuing bank releases the shipping documents to the buyer. The buyer uses these documents—especially the bill of lading—to take possession of the goods, clear customs, and complete the import process. If the LC was usance, the buyer’s obligation to pay matures on the agreed date, at which point the issuing bank debits the buyer’s account Most people skip this — try not to..
10. Settlement and Closure
All parties retain copies of the documents and the LC for their records. Any remaining obligations—such as refunds for overpayment, interest on usance credits, or fees charged by banks—are settled. The LC is then considered fulfilled and closed.
Conclusion
Letters of credit remain a cornerstone of secure international trade because they replace reliance on the counterparty’s creditworthiness with a bank‑guaranteed promise to pay. By clearly defining the documentary conditions and involving multiple banks—issuing, advising, confirming, and negotiating—the LC mitigates risks for both sellers and buyers, accommodates various payment timelines (sight, usance, standby), and supports complex arrangements such as transferable or revolving credits. While the process demands meticulous attention to document preparation and compliance, the protection it offers against non‑payment, political instability, and unfamiliar trading partners makes it an indispensable tool for businesses seeking to expand across borders with confidence.
