How a Letter of Credit Works: Step-by-Step Guide for Businesses
Introduction
International trade creates tremendous opportunities for businesses to expand beyond domestic markets. Companies import raw materials, export finished goods, and build global supply chains that connect buyers and sellers across continents. However, conducting business across borders also introduces financial uncertainty.
Exporters often worry about shipping goods without a guarantee of payment. Importers, on the other hand, want assurance that the goods they are paying for will be delivered according to the agreed terms.
To bridge this trust gap, international trade relies heavily on a financial instrument known as a Letter of Credit (LC).
A Letter of Credit provides a structured payment mechanism that protects both buyers and sellers by involving banks or financial institutions as intermediaries. It ensures that payment is made once the exporter fulfills specific documentation and shipment requirements.
Understanding how a Letter of Credit works is essential for businesses involved in international trade. In this guide, we will explain the process step by step, explore the parties involved, and highlight why Letters of Credit remain one of the most reliable payment mechanisms in global commerce.
What is a Letter of Credit?
A Letter of Credit is a financial guarantee issued by a bank on behalf of a buyer (importer) that assures payment to the seller (exporter) once the agreed conditions are fulfilled.
These conditions typically involve presenting specific documents that prove the goods have been shipped in accordance with the contract.
In simple terms, the bank takes responsibility for payment as long as the exporter complies with the terms of the Letter of Credit.
This arrangement significantly reduces the risks associated with international trade transactions.
Why Businesses Use Letters of Credit
Letters of Credit are widely used in global trade because they create a secure financial framework for transactions between companies that may not know each other well.
Key reasons businesses use Letters of Credit include:
- Ensuring payment security for exporters
- Protecting importers from paying before shipment
- Building trust between international trading partners
- Facilitating large cross-border transactions
- Reducing financial and contractual risk
Because banks are involved in verifying documentation and guaranteeing payment, both parties gain greater confidence in the transaction.
Parties Involved in a Letter of Credit Transaction
Before understanding how the process works, it is important to identify the main participants involved in a Letter of Credit transaction.
Applicant (Importer)
The applicant is the buyer who requests the Letter of Credit from their bank.
The importer is responsible for paying the issuing bank once the transaction conditions are fulfilled.
Beneficiary (Exporter)
The beneficiary is the seller who receives payment once the terms of the Letter of Credit are met.
The exporter must submit the required documents that confirm shipment of the goods.
Issuing Bank
The issuing bank is the financial institution that provides the Letter of Credit on behalf of the buyer.
It guarantees payment to the exporter if all documentation requirements are satisfied.
Advising Bank
The advising bank receives the Letter of Credit from the issuing bank and forwards it to the exporter.
It verifies the authenticity of the Letter of Credit before advising the beneficiary.
Confirming Bank (Optional)
In some transactions, another bank may confirm the Letter of Credit and guarantee payment in addition to the issuing bank.
This provides additional security for the exporter.
Step-by-Step Process of How a Letter of Credit Works
Although the structure of Letters of Credit may vary depending on the nature of the transaction, the overall process typically follows a series of well-defined steps.
Step 1: Buyer and Seller Agree on Trade Terms
The process begins when the importer and exporter negotiate a trade agreement.
This contract includes details such as:
- Product specifications
- Quantity and pricing
- Delivery timelines
- Shipping terms
- Documentation requirements
- Payment method
Both parties agree that payment will be made through a Letter of Credit.
Using an LC ensures that the transaction will be handled through a secure financial framework.
Step 2: Importer Requests a Letter of Credit
After the agreement is finalized, the importer approaches their bank and requests the issuance of a Letter of Credit.
The bank evaluates the importer’s financial standing and ability to meet the payment obligations.
If approved, the bank issues the Letter of Credit in favor of the exporter.
This document outlines all conditions that must be fulfilled before payment will be released.
Step 3: Letter of Credit is Sent to the Exporter
The issuing bank sends the Letter of Credit to the exporter’s bank, known as the advising bank.
The advising bank verifies the authenticity of the LC and forwards it to the exporter.
The exporter carefully reviews the document to ensure that all terms match the agreed contract.
If discrepancies are found, the exporter may request amendments before proceeding.
Step 4: Exporter Ships the Goods
Once the exporter confirms that the LC terms are acceptable, the production and shipment process begins.
The exporter ships the goods according to the agreed delivery schedule and collects the required documentation.
Typical documents required in a Letter of Credit transaction include:
- Commercial invoice
- Bill of lading
- Packing list
- Certificate of origin
- Inspection certificates
- Insurance documents (if applicable)
These documents serve as proof that the exporter has fulfilled the contractual obligations.
Step 5: Exporter Submits Documents to the Bank
After shipment, the exporter submits the required documents to their bank.
The bank examines the documents carefully to ensure that they comply with the conditions specified in the Letter of Credit.
This process is known as documentary compliance.
Banks follow strict guidelines when reviewing documentation, and even small discrepancies may delay payment.
Step 6: Documents Are Sent to the Issuing Bank
If the advising bank confirms that the documents meet the LC conditions, they are forwarded to the issuing bank.
The issuing bank performs its own verification to ensure that all requirements have been fulfilled.
Once compliance is confirmed, the payment process begins.
Step 7: Payment is Released to the Exporter
After successful document verification, the issuing bank releases payment to the exporter.
Depending on the type of Letter of Credit used, payment may be made immediately or after a specific credit period.
For example:
- Sight LC: Payment is made immediately upon document approval.
- Usance LC: Payment is deferred for a specified period.
This structured payment mechanism ensures that the exporter receives payment while protecting the interests of the importer.
Advantages of Using Letters of Credit
Letters of Credit offer several advantages that make them one of the most widely used financial instruments in international trade.

Exporters receive a bank-backed guarantee that payment will be made once conditions are met.
