The Most Common LC Discrepancies And How To Avoid Them.

Why banks reject documents under a letter of credit, and how to catch discrepancies before the first presentation.

By Ritam Bhattacharya, Head of Marketing8 Min Read1,670 WordsUpdated September 2026

An LC discrepancy is any difference between the documents presented and the terms of the letter of credit. The most common LC discrepancies are mismatched descriptions of goods, late shipment or late presentation, inconsistent amounts or quantities, and missing or wrongly issued certificates. Each one delays payment, and most are avoidable when the documents are checked against the LC before the bank sees them.

Key Takeaways

  • Banks examine documents only and never inspect the goods, so a small wording difference can hold up a payment for a perfectly good shipment.
  • The most common LC discrepancies fall into five groups: descriptions, dates, amounts and quantities, certificates, and transport document details.
  • Discrepancies begin upstream, when the contract, the purchase order and the LC drift apart during drafting.
  • Four automated checks, at creation, authoring, shipping and settlement, catch most errors before the first presentation.
  • ELCO (End to End Letter of Credit Orchestration) checks every document against the LC clauses before the bank sees it, and its benchmark is a document cycle of 5 days against 25 and a discrepancy rate of 5% against 35%.

What Is An LC Discrepancy

A letter of credit is a bank's undertaking to pay the seller when the seller presents documents that comply with the credit. Under UCP 600, the rules that govern most documentary credits, the bank examines the documents on their face and never inspects the cargo.

A discrepancy is any point where the documents fail that examination: a missed LC term, a conflict between two documents, or a breach of UCP 600 or standard banking practice. The standard is strict, because the bank pays against paper on the buyer's behalf.

When a bank finds a discrepancy it may refuse the documents, and it has up to five banking days after presentation to examine them and give notice. ELCO, End to End Letter of Credit Orchestration, is built to find those points first, while the seller still has time to fix them.

Why LC Discrepancies Happen

A trade passes through six stages: deal, contract, proforma invoice, LC, shipping and documents. Each is usually handled by a different desk with a different tool, so errors compound by the time documents reach the bank.

Contracts and LCs also go through rounds of manual iteration. Clauses are copied between emails and bank forms, amendments are agreed by phone, and the final LC terms drift from the original trade intent.

The forwarder, carrier, inspection agency and insurer who prepare the shipping documents often never see the LC itself. This is the gap ELCO closes: every stage writes to one record, so each party works from the same terms and the same timeline.

The Most Common LC Discrepancies, With Examples

DiscrepancyTypical ExampleHow ELCO Handles It
Description of goods differsThe invoice abbreviates or rewords the description given in the LCCross-checks the description across invoice, bill of lading and LC, naming the clause any mismatch breaks
Late shipmentThe on-board date on the bill of lading falls after the latest shipment dateFlags a late shipment date against the LC before presentation
Late presentation or expired creditDocuments reach the bank more than 21 days after shipment, or after expiryFlags late presentation dates against the credit and raises delay alerts
Amounts, quantities or currency disagreeInvoice value exceeds the LC amount, or quantities fall outside the allowed toleranceFlags quantity and amount differences across every document in the set
Missing or wrongly issued certificateA certificate of origin or inspection is absent, unsigned or issued by a party the LC did not nameFlags missing certificates against the documents the LC calls for
Transport document errorsThe bill of lading shows the wrong port, consignee or notify party, or carries a clause about damaged packagingCreates bills of lading and cross-checks them against the LC clauses

Other frequent problems include late or insufficient insurance cover, drafts drawn on the wrong party, missing endorsements, and an LC that disagrees with the purchase order. ELCO flags LC versus purchase order mismatches as soon as the LC is authored, and the AskIsta LC Compliance Agent names the clause behind every flag.

What Happens When A Bank Finds A Discrepancy

The bank issues a notice of refusal listing every discrepancy. If the presentation period and the expiry date allow, the seller can correct and re-present the documents. If time has run out, the issuing bank asks the buyer whether it will waive the discrepancies.

A waiver puts the decision in the buyer's hands, and in a falling market a buyer may use a minor discrepancy to renegotiate the price. The seller has goods on the water and a discrepancy fee to pay.

The cost is wider than the fee. Payment arrives later, working capital stays locked and demurrage can build. Where a document has already reached the bank, ELCO drafts the amendment or waiver request from the same record, so every party sees the same version.

How To Avoid Common LC Discrepancies With ELCO

ELCO runs four checks across the life of the credit. Each one removes a class of error at the point where it is cheapest to fix.

  1. At creation. ELCO generates the LC from the approved contract, so goods, quantity, price, Incoterms and dates are carried across and interpreted against the trade intent.
  2. At authoring. ELCO flags mismatches between the LC and the purchase order instantly, and deal terms flow into contract clauses with version history.
  3. At shipping. ELCO creates bills of lading, invoices and certificates and cross-checks them against the LC clauses, and against each other, before the first bank presentation.
  4. At settlement. ELCO calculates laytime, demurrage and dispatch automatically and runs reconciliation with delay alerts.

Because the invoice, packing list and bill of lading all draw on one record, they cannot describe the goods three different ways.

Letter Of Credit Vs Bank Guarantee

The two instruments are often confused, and the difference explains why LC documents are examined so strictly. A letter of credit is the payment method: the bank pays the seller when compliant documents are presented. A bank guarantee is a safety net: the bank pays only if the buyer fails to perform.

Under an LC the documents trigger payment in the normal course of trade, so every presentation is examined. Under a guarantee documents matter only if a demand is made.

How ELCO And AskIsta Reduce Common LC Discrepancies

ELCO runs the contract, the LC, the shipping documents and settlement as one governed thread from offer to payment, alongside the ERP, EXIM tools and bank portals a trader already uses.

Four AskIsta agents work on each trade. The Contract Agent drafts and amends contracts and LCs. The LC Compliance Agent detects discrepancies before bank submission and names the clause each one breaks. The Logistics Agent aligns shipping documents, bills of lading and invoices. The Claims Agent handles laytime, demurrage and settlement. Their role is explained in AI copilots, agents and autonomous employees.

The ELCO benchmark is a document cycle of 5 days against 25, and a discrepancy rate of 5% against 35%. Agreed terms are enforced by a smart contract policy engine, and each party works under a verified identity, as described on the governance and security page.

Frequently Asked Questions

What are the most common LC discrepancies?

The most frequent are a description of goods that differs from the LC, shipment after the latest shipment date, presentation after the allowed period or after expiry, amounts or quantities that disagree across documents, and certificates that are missing, unsigned or issued by the wrong party. Errors on the bill of lading and insurance document follow closely behind.

How long does a bank have to examine documents under UCP 600?

Each bank has a maximum of five banking days following the day of presentation to decide whether the documents comply. If it refuses, it must give a single notice stating every discrepancy it relies on. Presenting early leaves time for correction before the credit expires.

What is the presentation period under a letter of credit?

Where the credit requires an original transport document and states no other period, UCP 600 requires presentation within 21 calendar days after the date of shipment, and in any case before the credit expires. Many LCs set a shorter period, so the figure written in the credit itself always governs.

Can a discrepancy be corrected after the bank refuses the documents?

Yes, if there is time. The seller may replace or correct the document and present again within the presentation period and before expiry. Documents issued by third parties, such as the carrier or an inspection agency, must be corrected by that issuer. If time has run out, the only route is a waiver from the buyer.

What software helps prevent LC discrepancies?

Letter of credit automation software such as ELCO checks every shipping document against the LC clauses before presentation and names the clause each mismatch breaks. The bank still examines every presentation, but errors are fixed while there is still time. The ELCO benchmark is a discrepancy rate of 5% against 35%.
