International trade involves complex financial instruments, and one of the most secure methods of payment is the Irrevocable Documentary Acceptance Credit (IDAC). As someone who has worked in trade finance for years, I understand how daunting these terms can be for beginners. This guide breaks down IDACs in plain English, explains their mechanics, and shows why they are vital for secure cross-border transactions.

What Is an Irrevocable Documentary Acceptance Credit?
An Irrevocable Documentary Acceptance Credit (IDAC) is a type of letter of credit (LC) where a bank guarantees payment to the seller (exporter) once they present compliant documents and a time draft (a post-dated payment instrument). Unlike a revocable LC, an IDAC cannot be canceled or modified without all parties’ consent, making it a safer option for exporters.
Key Features of an IDAC
- Irrevocable: The terms cannot be changed unless all parties agree.
- Documentary: Payment depends on submitting the correct trade documents.
- Acceptance Credit: The bank “accepts” a time draft, promising payment at a future date.
How Does an IDAC Work?
Let me walk you through a typical IDAC transaction step by step:
- Buyer and Seller Agree on Terms: The buyer (importer) and seller (exporter) agree to use an IDAC for payment.
- Buyer Applies for an IDAC: The buyer requests their bank (issuing bank) to open an IDAC in favor of the seller.
- Issuing Bank Issues the IDAC: The bank assesses the buyer’s creditworthiness and issues the IDAC, sending it to the seller’s bank (advising bank).
- Seller Ships Goods and Submits Documents: The seller ships the goods and submits required documents (invoice, bill of lading, insurance policy, etc.) along with a time draft to their bank.
- Bank Examines Documents: The advising bank checks if the documents comply with the IDAC terms. If compliant, the bank “accepts” the draft.
- Payment at Maturity: The seller can hold the accepted draft until maturity or discount it for immediate cash. At maturity, the bank pays the seller.
Example Calculation: Discounting an Accepted Draft
Suppose a seller presents a 90-day time draft for $100,000, and the bank accepts it. If the seller needs immediate cash, they can discount it at an annual rate of 6%.
The discount amount is calculated as:
Discount = Principal \times \left( \frac{Interest\ Rate \times Days\ to\ Maturity}{360} \right)Plugging in the numbers:
Discount = 100,000 \times \left( \frac{0.06 \times 90}{360} \right) = 100,000 \times 0.015 = 1,500The seller receives:
100,000 - 1,500 = 98,500This means the seller gets $98,500 immediately instead of waiting 90 days for the full amount.
Why Use an IDAC?
Benefits for Sellers
- Payment Security: The bank’s acceptance acts as a guarantee.
- Liquidity Option: Sellers can discount the draft for early payment.
- Reduced Risk of Non-Payment: Unlike open account terms, IDACs ensure payment if documents comply.
Benefits for Buyers
- Deferred Payment: Buyers get time (e.g., 30, 60, or 90 days) before payment is due.
- Assured Delivery: Goods are only released if compliant documents are presented.
IDAC vs. Other Trade Finance Instruments
| Feature | IDAC | Sight LC | Bank Guarantee | Open Account |
|---|---|---|---|---|
| Payment Timing | Deferred (time draft) | Immediate | Conditional | After delivery |
| Risk to Seller | Low (bank guarantee) | Low (immediate payment) | Medium (claim process) | High (buyer default) |
| Risk to Buyer | Medium (documents control) | High (upfront payment) | Low (only if triggered) | Low (pay later) |
| Flexibility | Fixed terms | Fixed terms | Customizable | Highly flexible |
Common Pitfalls and How to Avoid Them
1. Discrepancies in Documents
Banks reject documents for minor errors (e.g., misspelled names, incorrect dates). I’ve seen deals fail because of a single typo. Solution: Use a professional document checker.
2. Misunderstanding Draft Tenor
If a seller expects immediate payment but the IDAC has a 60-day draft, they may face cash flow issues. Solution: Clarify payment terms before shipment.
3. Bank’s Credit Risk
If the accepting bank faces financial trouble, the seller may not get paid. Solution: Work with reputable banks.
Real-World Application: A U.S. Exporter’s Case Study
Let’s say ABC Manufacturing in Texas exports machinery to XYZ Imports in Germany. They agree on a 60-day IDAC for $500,000.
- Step 1: XYZ’s German bank issues the IDAC.
- Step 2: ABC ships the goods and submits documents to their U.S. bank.
- Step 3: The U.S. bank confirms compliance and accepts the draft.
- Step 4: ABC discounts the draft at 5% annual interest:
Discount = 500,000 \times \left( \frac{0.05 \times 60}{360} \right) = 4,166.67 - Step 5: ABC receives 500,000 - 4,166.67 = 495,833.33 immediately.
Without the IDAC, ABC might have waited 60 days or faced non-payment risk.
Regulatory and Economic Considerations in the U.S.
The U.S. Uniform Commercial Code (UCC) Article 5 governs letters of credit, including IDACs. Key points:
- Banks must honor compliant documents strictly.
- Fraud exceptions exist, but courts rarely interfere if documents are clean.
Economic Impact:
- Small businesses benefit from IDACs by reducing trade risks.
- Post-pandemic, supply chain disruptions have increased demand for secure payment methods like IDACs.
Final Thoughts
An Irrevocable Documentary Acceptance Credit is a powerful tool for securing international trade. It balances risk between buyers and sellers while providing liquidity options. If you’re new to trade finance, start by consulting your bank and ensuring all documents are error-free. Over time, you’ll see how IDACs can make global trade smoother and safer.
