Letters of Credit Process: 7 Key Steps

published on 30 October 2025

Letters of credit (LCs) are a secure payment method for international trade, guaranteeing payment to exporters once specific conditions are met. They protect importers and exporters from financial risks, particularly in cross-border transactions. For UK businesses, LCs are especially useful when working with new partners or trading in regions with uncertain legal protections.

Key Points:

  • What is an LC? A bank-issued guarantee ensuring payment upon meeting agreed terms.
  • Why use it? Reduces payment risks, ensures smooth transactions, and supports cash flow.
  • Who’s involved? Importer (applicant), exporter (beneficiary), and banks (issuing, advising, and confirming).

The 7 Steps:

  1. Sales Contract Agreement: Define clear terms, goods, pricing, and required documents.
  2. Application for LC: Importer requests the LC from their bank, providing key details.
  3. LC Issuance and Notification: The issuing bank sends the LC to the exporter’s bank.
  4. Goods Shipment: Exporter ships goods as per the LC terms and prepares documentation.
  5. Document Submission: Exporter submits documents to the bank for verification.
  6. Document Review and Payment: Banks verify compliance and release payment to the exporter.
  7. Document Release and Goods Receipt: Importer collects documents to claim shipped goods.

Benefits and Risks:

  • Benefits: Secure payments, reduced credit risks, and improved cash flow.
  • Risks: High fees, strict documentation requirements, and potential delays due to errors.

By understanding these steps and preparing accurate documentation, UK businesses can use LCs to trade internationally with confidence. For expert advice, companies like Oku Markets can provide tailored support in managing LCs and mitigating risks.

Who is Involved in the LC Process

A letter of credit (LC) transaction involves three key players, each with distinct responsibilities that ensure the process runs smoothly. Let’s break down the roles, starting with the importer.

The Applicant (Importer)

The applicant, or importer, is the party that initiates the letter of credit process. After finalising a sales agreement with the exporter, the importer approaches their bank to request the LC facility. For businesses in the UK, this often involves working with a domestic bank familiar with local trade practices and regulations.

The importer’s job is to ensure the LC terms align perfectly with the sales contract. This includes specifying details like the goods being purchased, quantities, prices (commonly in GBP), and delivery conditions. They are also responsible for covering any bank charges and ensuring full payment is made once the required documents are verified.

Take, for instance, a real-world example from 2022: HSBC UK facilitated a transaction for a British company importing machinery from Germany. The importer applied for the LC through HSBC, ensuring all contract terms were accurately included. The process was completed in just 14 days, showing how careful preparation by the applicant can make things more efficient.

Next, let’s look at the role of the exporter, known as the beneficiary.

The Beneficiary (Exporter)

The beneficiary is the exporter who receives payment under the letter of credit. Their role is crucial because they must meet the exact terms of the LC, which includes shipping the goods as specified and providing all necessary documentation. This typically involves preparing documents like commercial invoices, bills of lading, certificates of origin, and insurance papers. Even small errors or discrepancies in these documents can lead to delays or, worse, non-payment.

Once the goods are shipped, the exporter must quickly compile and submit all the required documents to the bank within the stated timeframe. For exporters working with UK importers, it’s also essential to ensure compliance with UK customs regulations, especially for goods entering British ports.

Banks in the Process

Banks play a central role in facilitating LC transactions, creating a secure system that benefits both importers and exporters. They ensure each step of the process is verified and trustworthy.

  • Issuing Bank: This is the importer’s bank, responsible for creating and issuing the letter of credit. It guarantees payment to the exporter once all documents meet the required standards, taking on the financial risk of the transaction. For UK importers, the issuing bank is often a British institution with expertise in both local and global trade standards.
  • Advising Bank: Typically the exporter’s bank, this institution verifies the authenticity of the LC, communicates its terms to the exporter, and serves as the intermediary for document submission. In many cases, the advising bank also acts as the nominated bank, helping streamline the process.
  • Confirming Bank: In transactions with higher risks, a confirming bank may be involved. This bank provides an additional payment guarantee, ensuring the exporter has extra security by backing the issuing bank’s promise.

Here’s a quick summary of the roles of these banks:

Bank Type Primary Role Key Responsibilities
Issuing Bank Guarantees payment Issues the LC, reviews documents, and pays the exporter upon compliance
Advising Bank Verifies authenticity Informs the exporter of the LC terms and assists with document checks
Confirming Bank Adds payment guarantee Ensures payment to the exporter if the issuing bank fails to fulfil its obligations

UK banks generally adhere to the Uniform Customs and Practice for Documentary Credits (UCP 600), a set of international standards that ensure consistency and reliability in trade transactions.

The 7 Steps in the Letters of Credit Process

The letters of credit (LC) process is a structured way for UK businesses to manage international trade, reducing risks and ensuring smooth transactions. Each step builds upon the previous one, guiding businesses from the initial agreement to receiving the goods.

Step 1: Sales Contract Agreement

The process begins with a detailed sales contract that specifies LC payment terms and includes precise details about the goods, quantities, pricing, and delivery terms. It must also state the currency, adopt recognised Incoterms, and list all required documentation.

Ambiguity in contracts is a major source of LC issues, so clarity is key. Include exact product descriptions, quality standards, packaging details, and shipping deadlines. For UK importers, aligning the contract with local customs regulations and including provisions for special certifications - such as those required for goods entering British ports - is essential.

Common mistakes at this stage include vague delivery terms, missing document requirements, or unclear product specifications. Addressing these early can save significant time and hassle down the line.

Step 2: Application for Letter of Credit

Once the sales contract is finalised, the importer applies for an LC. This involves submitting documents like the signed contract, proforma invoice, purchase order, and beneficiary's banking details to the issuing bank. The bank then evaluates the importer’s creditworthiness and the transaction risk, a process that typically takes 2–5 business days.

The issuing bank may require security measures, such as cash deposits or guarantees, based on the importer’s financial standing. For a successful application, UK businesses should ensure all beneficiary details are accurate, specify the exact LC amount and currency, set realistic shipment and expiry dates, and provide a clear list of required documents.

Step 3: LC Issuance and Notification

Once approved, the issuing bank prepares the LC and sends it to the advising bank. The advising bank verifies the LC's authenticity and notifies the beneficiary (exporter).

This step protects exporters from fraudulent LCs and ensures compliance with international standards under UCP 600 rules. In some cases, a confirming bank may be involved to add an extra layer of payment security by guaranteeing the LC. This assurance can be particularly useful in high-risk transactions, providing exporters with greater confidence as they prepare to fulfil the order.

Step 4: Goods Shipment

After agreeing to the LC terms, the exporter ships the goods as specified in the contract. Compliance with product details, quantities, packaging, and shipping methods is critical.

The exporter must then prepare all required documents, including the commercial invoice, bill of lading, packing list, and insurance certificate. For UK-bound goods, additional documents may be necessary to meet customs requirements.

Accuracy in documentation is essential. Even minor errors, such as mismatched dates or incorrect descriptions, can lead to payment delays or outright rejection. Ensuring all documents align perfectly with the LC terms is a must.

Step 5: Document Submission

Following shipment, the exporter submits the required documents to the advising or nominated bank. This must be done within the timeframe specified in the LC, often within 21 days from the shipment date.

Banks operate on a "strict compliance" basis during document reviews, meaning even small discrepancies can result in rejection. Common issues include missing signatures, incorrect dates, or mismatched descriptions. Many exporters work with freight forwarders or trade finance experts to ensure their documentation is error-free before submission, reducing the risk of rejection.

Step 6: Document Review and Payment

The bank reviews the submitted documents against the LC terms, typically taking 3–5 banking days to complete this process.

If the documents meet all requirements, the bank forwards them to the issuing bank and releases payment to the exporter. Payment methods vary depending on the LC type and may include immediate payment, acceptance of a draft, or deferred payment arrangements.

If discrepancies are found, the bank notifies the exporter with a list of issues. The exporter can then correct and resubmit the documents or request a waiver from the importer for minor discrepancies. Payment is only released when all terms are fully satisfied.

Step 7: Document Release and Goods Receipt

After payment, the issuing bank releases the documents to the importer. These documents are essential for claiming and clearing the goods through UK customs.

The importer uses the bill of lading to collect the goods from the port or freight terminal and submits other documents, such as the commercial invoice and packing list, to HMRC for customs clearance. This process involves paying duties, VAT, or other charges based on the goods’ classification and value.

Attention to import regulations is critical, especially for goods requiring special licences or meeting safety standards. Accurate documentation ensures smooth customs clearance and compliance with UK import laws.

From start to finish, the LC process generally takes 7–21 days, depending on factors like document accuracy, bank processing times, and shipping arrangements. By following this structured approach, both importers and exporters can conduct international trade with greater security and confidence.

Benefits and Risks of Letters of Credit

Letters of credit (LCs) provide UK businesses with a secure way to navigate international trade. However, like any financial tool, they come with both advantages and potential drawbacks. Knowing these trade-offs can help businesses decide when and how to use LCs effectively.

Benefits for UK Businesses

One of the key advantages of LCs is the security they offer. Exporters are assured of payment, while importers only pay once the agreed terms - such as shipment of goods - are met. This provides peace of mind, especially when dealing with new partners or trading in less familiar markets.

Banks play a vital role by reducing counterparty risk, which not only makes transactions safer but can also open doors to new business opportunities and markets.

LCs also help businesses manage their cash flow better. Many banks offer trade finance options tied to LCs, giving companies access to additional funding to support their operations.

But as with any financial arrangement, these benefits come with challenges that need careful consideration.

Risks and Challenges

The LC process relies heavily on precise documentation, and even minor errors can disrupt the transaction. For instance, if a UK exporter shipping machinery to Asia submits a certificate of origin that doesn’t meet LC requirements, the payment could be delayed until the issue is resolved.

Cost is another concern. Banks charge fees for issuing, amending, confirming, and negotiating LCs, and additional costs like courier and documentation fees can quickly add up. For smaller transactions, these expenses might outweigh the benefits.

Compliance requirements add another layer of complexity. Strict documentation standards and coordination between multiple parties - such as the importer, exporter, and banks - leave room for mistakes. Physical document handling can also lead to issues like human error, forgery risks, or courier delays, further complicating matters.

Currency fluctuations and regulatory changes can affect LC terms, introducing additional uncertainty for businesses.

Benefits vs Risks Comparison

Aspect Benefits Risks
Security Payment guaranteed if LC terms are met Importer’s account may be debited before goods are received
Risk Management Reduces credit risk with bank involvement Errors in documents can delay or block payment
Trust & Relationships Builds trust and supports new partnerships Coordination with multiple parties can be challenging
Documentation Provides a clear paper trail for customs and regulations Physical documents can be prone to errors, delays, or even forgery
Flexibility Amendments allow for adjustments when needed Amendments require agreement from all parties, adding time and cost
Financial Impact Access to trade finance and reduced risk High fees for LCs and related services can be costly

Balancing the benefits and risks of LCs is essential for successful transactions. Factors like the value of the trade, the trust level with partners, and the destination market all play a role in determining whether an LC is the right choice. For high-value transactions or deals with new partners, the added security often justifies the costs and complexity. On the other hand, simpler payment methods might suffice for established relationships.

To make the most of LCs, businesses should invest in regular training and seek professional advice. This can help them navigate compliance requirements, manage currency risks, and avoid costly mistakes, ensuring smoother international trade operations.

FAQs

What steps can UK businesses take to ensure their documentation is accurate when using letters of credit?

When handling letters of credit, UK businesses need to meticulously review every term and condition outlined in the credit. Key details like dates, amounts, and product descriptions must align perfectly with the contract to avoid complications.

Collaborating with your bank or a trade finance expert is equally important. They can help verify that all documents, such as invoices, shipping paperwork, and certificates, meet the credit’s requirements. Taking the time to double-check these documents can prevent discrepancies that might cause payment delays. By dedicating effort to understanding the process and relying on expert advice, you can significantly reduce errors and ensure transactions proceed smoothly.

What risks are associated with letters of credit, and how can businesses address them?

Letters of credit play a key role in international trade, but they aren't without challenges. Common risks include errors in documentation, which can cause payment delays or disputes, and political or economic instability in the buyer's country, potentially disrupting the transaction. On top of that, businesses often grapple with currency exchange risks due to unpredictable rate fluctuations.

To address these issues, it's essential to double-check that all documentation is accurate and meets the terms outlined in the letter of credit. Collaborating with skilled trade finance professionals can simplify this process and reduce errors. Additionally, businesses can adopt currency management tools, like forward contracts, to shield themselves from volatile exchange rates. Oku Markets offers tailored solutions designed to help businesses tackle these challenges with confidence.

When is it most beneficial for a business to use a confirming bank in the letter of credit process?

Using a confirming bank can provide peace of mind for exporters who might have doubts about the issuing bank's reliability or are worried about potential political or economic instability in the issuing bank's country. By involving a confirming bank - usually based in the exporter’s own country - the risk of non-payment is significantly lowered. This is because the confirming bank guarantees payment as long as the terms and conditions outlined in the letter of credit are fully met.

This extra layer of assurance is particularly helpful for exporters venturing into new markets or working with buyers they’re not familiar with. It helps ensure smoother transactions and builds confidence that payment will be received without complications.
