Definition: Letter-of-credit business
Letter-of-credit business includes all transactions in which a bank, on behalf of its customer, undertakes an irrevocable payment obligation toward a beneficiary.
Basic functionality
A letter of credit functions as a three-party legal relationship between the applicant (buyer), the beneficiary (seller), and the issuing bank. The bank is obligated to make payment as soon as the beneficiary submits the agreed documents.
- Irrevocable payment commitment by the bank
- Document-based processing
- Legal separation from the underlying transaction
Letter-of-credit business vs. other payment methods
Unlike advance payments or open-account invoices, the letter of credit offers security to both parties. While Payment Terms often involve one-sided risks, the letter of credit creates a balanced alignment of interests.
Importance in modern procurement
For procurement organizations, letter-of-credit business enables the secure development of new supplier markets and supports strategic sourcing initiatives in emerging markets. It complements modern E-Procurement in complex international transactions.
Methods and procedures
The processing of letter-of-credit transactions follows standardized procedures that vary depending on the type of transaction and risk structure.
Documentary letter of credit procedure
The documentary letter of credit is the standard method in international trade. The supplier receives payment upon presentation of specified documents such as commercial invoices, transport documents, and certificates of origin.
- Letter-of-credit application by the buyer
- Review and issuance by the bank
- Submission of documents by the seller
- Document review and payment
Standby letter of credit process
Standby letters of credit serve as a security instrument and are only drawn upon if the primary obligation is not fulfilled. They are particularly suitable for long-term Blanket Purchase Order with established suppliers.
Digital letter-of-credit processing
Modern platforms enable the electronic processing of letters of credit and significantly reduce processing times. Integration into ERP Integration automates workflows and improves transparency for procurement teams.
Key KPIs for letter-of-credit transactions
Measuring the success of letter-of-credit transactions requires specific metrics that reflect both efficiency and risk management.
Processing efficiency metrics
The average processing time from letter-of-credit issuance to payment is a key indicator of process quality. Benchmark values are 5-7 business days for standard transactions.
- Letter-of-credit cycle time (days)
- First-pass rate in document review (%)
- Number of discrepancies per letter of credit
Cost-efficiency metrics
Letter-of-credit costs as a percentage of transaction volume enable benchmarking and negotiations with banks. Typical values range between 0.1% and 0.5% for standard transactions.
Risk and compliance indicators
The success rate of letter-of-credit payments and the number of legal disputes reflect the quality of Purchase Terms and Conditions and supplier selection.
Risks, dependencies, and countermeasures
Despite the inherent security of letters of credit, specific risks exist that can be minimized through appropriate measures.
Document risks and compliance
Discrepancies in letter-of-credit documents lead to payment delays or refusals. Common sources of error include incomplete transport documents or deviating product descriptions.

Practical example
A German automotive supplier sources critical electronic components from a new supplier in Taiwan. Due to the partner's unfamiliarity and the high transaction volume of 2 million euros, an irrevocable documentary letter of credit is agreed upon. The supplier receives payment security, while the buyer uses document review to ensure that the goods are delivered according to specification. The letter-of-credit costs of 0.3% are more than offset by risk minimization and an improved negotiating position.
- Reduction of default risk to nearly zero
- Improved cash flow planning for both parties
- Establishment of a trusting business relationship

Letter-of-credit business is currently undergoing a phase of digitization and standardization, opening up new opportunities for efficient procurement processes.

- Automated smart contracts
- Real-time monitoring of transactions
- Reduced documentation errors

Opening a letter of credit typically takes 2-3 business days, and document review takes another 3-5 business days. In complex transactions or in the case of discrepancies, processing can extend to up to 14 days.
What costs arise in letter-of-credit transactions?
Letter-of-credit fees consist of opening fees, ongoing commissions, and processing fees. Total costs usually range between 0.1% and 2% of the transaction volume, depending on term, complexity, and banking relationship.
Can letters of credit be amended afterward?
Amendments to letters of credit are possible, but they require the consent of all parties involved. Every amendment causes additional fees and may delay processing. Therefore, letter-of-credit terms should be formulated precisely from the outset.
