Letters of credit: securing your international transactions

Is your company involved in international trade? Are you looking to secure your payments with foreign partners? The letter of credit is a strategic financial tool to protect your interests. Let's find out together how this instrument can transform your approach to international transactions.
Understanding the letter of credit mechanism
How it works
When you use a letter of credit, also known as a documentary credit, you benefit from a bank commitment that guarantees payment for your international transaction. This sophisticated mechanism protects your interests by involving several parties: you, your trading partner, and your respective banks.
The key players in your transaction
To secure your international trade, you need to control the involvement of four main players:
- You, as principal (if you are an importer) or beneficiary (if you are an exporter)
- Your sales partner
- Your bank
- Your partner's bank
The process that protects your interests
Here's how to set up your letter of credit:
- Negotiate your commercial contract
- Ask your bank to open a letter of credit
- Wait for your bank to issue the letter of credit
- Check the notification to your partner
- Supervise shipment of merchandise
- Submit your compliant documents
- Receive your payment after verification
ℹ️ Imagine that your company imports electronic components from Asia for 250,000 euros. With a letter of credit, you pay only on receipt of the correct documents, while your supplier is assured of payment as soon as the goods are shipped.
The different types of letters of credit available to you

Irrevocable letter of credit
The efficient management of your international transactions requires the right tools. By choosing an irrevocable letter of credit, you obtain the most solid commitment: no modification is possible without the agreement of all parties.
Confirmed letter of credit
For maximum security, opt for a confirmed letter of credit. In this case, you benefit from the additional guarantee of a second bank, generally located in your own country if you are an exporter.
Transferable letter of credit
This option allows you, as the primary beneficiary, to transfer your rights to other beneficiaries. It is particularly useful if you are managing triangular operations.
ℹ️ Take the example of a textile customer who uses a confirmed letter of credit for his purchases in India. This double guarantee enables him to establish a lasting business relationship, even without any prior history.
