Reading a Letter of Credit Like an Auditor
The goods shipped, the customer is satisfied, and the bank refuses payment because a document says Rotterdam and the credit says Rotterdam Port. That is how documentary credit works.
A letter of credit is a bank undertaking to pay against a compliant presentation of specified documents, independent of the underlying commercial performance. Banks examine documents on their face against the credit terms, and any inconsistency is a discrepancy that entitles the bank to refuse payment. Most discrepancies are clerical rather than substantive, which means most of them are preventable by checking the presentation before it is submitted.
- Payment depends on the documents, not on whether the goods arrived or the customer is happy.
- Banks examine on the face of the documents. An internal inconsistency between two of your own documents is enough to create a discrepancy.
- The most common discrepancies are clerical: dates, descriptions, spellings, missing endorsements and late presentation.
- A discrepant presentation does not always mean no payment, but it converts a bank obligation into a customer decision, which is a materially weaker position.
- ChatFin reads the credit and the presentation documents together and reports every inconsistency before the pack is submitted.
There is a persistent misunderstanding about letters of credit among people who have not worked with them, which is that they guarantee payment for goods delivered.
They do not. They guarantee payment against a compliant presentation of documents. The bank does not inspect the cargo, contact the buyer or assess whether the contract was performed. It examines the documents against the credit terms, on their face, and if anything is inconsistent it may refuse to pay. The goods can be sitting in the buyer's warehouse and the presentation can still be refused because an invoice describes the goods differently from the credit.
This page covers what banks actually check, where discrepancies come from, why a discrepant presentation weakens your position even when payment eventually arrives, and how to check the pack yourself before it goes in.
The principle that surprises people
Documentary credits operate on two doctrines that together explain almost every dispute. The first is independence: the credit is separate from the underlying sales contract, and the bank deals only with the credit. The second is strict compliance: the documents must conform to the terms as written.
The practical effect is that commercial performance is irrelevant to the payment decision. A perfectly executed shipment with an imperfect document set can be refused, and a technically compliant presentation must generally be paid even where the commercial relationship has soured.
| What the bank examines | The documents specified in the credit, against the credit terms and against each other |
| What the bank does not examine | The goods, the contract, the commercial relationship or whether delivery occurred |
| Examination period | A limited number of banking days after presentation, within which the bank must accept or refuse |
| Refusal notice | Must state the discrepancies, which is why a refusal is at least specific and actionable |
| Consequence | A discrepant presentation puts the payment decision back with the buyer, who may waive or may not |
Where discrepancies actually come from
A large share of presentations are refused on first submission, and the reasons are consistently mundane. These are not sophisticated failures, which is precisely why they are worth checking for systematically.
Description mismatch
The goods description on the invoice does not correspond to the credit. Banks look for correspondence with the credit wording, and paraphrasing creates exposure.
Date problems
Presentation after the expiry or after the presentation period, a transport document dated after the latest shipment date, or an inconsistent date sequence across documents.
Internal inconsistency
Two of your own documents disagreeing on quantity, weight, marks, consignee or port. The bank does not decide which one is right.
Missing or defective elements
An absent endorsement, an unsigned certificate, a missing original, or a document not showing what the credit required it to show.
Type three deserves emphasis because it is entirely within your control. The invoice, packing list, transport document and certificates are produced by different people at different times, and reconciling them against each other before presentation eliminates a substantial share of refusals.
What a discrepancy actually costs
Discrepancies are often treated as a paperwork nuisance because the buyer usually waives them and payment eventually arrives. That framing understates the cost in three ways.
The fourth point is the one that matters most in a deteriorating relationship, and it is exactly when nobody has time to check documents carefully.
The trade finance tooling
Trade finance platforms handle the transaction lifecycle. Surecomp and Bolero manage credits, presentations and bank communication digitally, and treasury systems such as Kyriba track exposure and instrument status. Trade documentation and customs platforms such as Descartes handle the export documentation itself.
The checking step is where the tooling has historically been thinnest. Examination against the credit is a reading task requiring comparison of unstructured documents against unstructured conditions, and in most organisations it is done by an experienced person under time pressure at the end of a shipment cycle, or not at all.
Reading a credit and testing a document set against it is exactly the combination of contract intelligence and document processing pre built finance AI agents provide.
Checking the pack before it goes in
A self examination before presentation is the single highest return activity in this process, and it follows a fixed order.
Extract every condition from the credit
List each document required, each element it must show, and every date constraint. Conditions buried in narrative clauses are the ones most often missed.
Check dates first
Expiry, latest shipment date, presentation period and the date sequence across documents. Date failures are fatal and unfixable after the fact, so they are checked first.
Check the goods description against the credit wording
Look for correspondence with the credit rather than a commercially equivalent description.
Cross check documents against each other
Quantity, weight, marks, consignee, ports and vessel across every document in the set. Any disagreement is a discrepancy regardless of which is correct.
Check completeness and form
Originals, signatures, endorsements and any specific certification wording the credit demands.
Running steps two and four alone removes most first submission refusals, and both are mechanical comparisons rather than judgement calls.
How ChatFin examines the presentation
ChatFin reads the credit itself and extracts the required documents, the elements each must show and every date constraint into a structured condition set, including conditions expressed in narrative clauses rather than in a formal list.
The document processing agent then reads each presentation document and structures its content: goods description, quantities, weights, marks, parties, ports, dates, signatures and endorsements. The autonomous reconciliation agent tests every document against the credit conditions and against every other document, and reports each inconsistency with both sources shown, so the preparer sees the disagreement rather than a flag.
| Contract intelligence | Extracts required documents, mandated elements and date constraints from the credit text |
| Document processing | Structures invoice, transport, packing and certificate documents into comparable fields |
| Reconciliation agent | Tests each document against the credit and cross checks all documents against each other |
| Pattern recognition | Identifies recurring discrepancy types across shipments so the root cause can be fixed |
| Data query agent | Answers questions such as which credits expire within the next fourteen days |
The examination is advisory. ChatFin produces the discrepancy list with the evidence, and your trade finance team decides what to correct and what to present, which keeps the commercial judgement where it belongs.
Reducing refusals on the next shipment
Improvement here is fast because the failure modes repeat.
Categorise last year's refusals
Group every discrepancy notice by type. The distribution is usually concentrated in two or three causes.
Fix the document templates
Most description and formatting failures originate in a template rather than in a person, and correcting the template fixes every future shipment.
Introduce the cross check
Compare all documents against each other before presentation. This is mechanical and catches the internal inconsistency category entirely.
Track the date constraints centrally
Expiry and latest shipment dates monitored against actual shipping progress, so a timing failure is visible while it can still be avoided.
The fourth step prevents the category that cannot be corrected afterwards, which makes it the most valuable even though it is the least technical.
The goods can be sitting in the buyer's warehouse and the presentation can still be refused, because the bank never looks at the goods.

Frequently Asked Questions
What is a discrepancy in a letter of credit?
It is any inconsistency between the documents presented and the terms of the credit, or between the documents themselves. Banks examine documents on their face against the credit terms, so a goods description that does not correspond to the credit wording, a date outside a permitted window, or two of your own documents disagreeing on quantity or consignee are each sufficient to entitle the bank to refuse payment.
Why are most letter of credit presentations refused?
Because of clerical failures rather than substantive ones. The most common categories are goods descriptions that do not correspond to the credit wording, date problems such as late presentation or a transport document dated after the latest shipment date, internal inconsistencies between the presenter's own documents, and missing elements such as an endorsement, a signature or a required original.
What happens if a presentation is discrepant?
The bank issues a refusal notice specifying the discrepancies. Payment may still follow if the buyer waives them, and documents can sometimes be corrected and re presented if the credit has not expired. The significant change is that a compliant presentation obliges the bank to pay, while a discrepant one puts the decision back with the buyer, which is a materially weaker position particularly if the commercial relationship is under strain.
Can ChatFin check letter of credit documents?
Yes. ChatFin extracts the required documents, mandated elements and date constraints from the credit text, including conditions expressed in narrative clauses, then structures each presentation document and tests it against the credit and against every other document in the set. It reports each inconsistency with both sources shown, so your trade finance team can see the disagreement and decide what to correct before submitting.
