Guide · Payment
A documentary credit — commonly called a letter of credit or L/C — replaces your buyer’s promise to pay with a bank’s promise to pay. The bank pays when you present documents that comply with the credit. Not when the goods arrive, not when the buyer is satisfied: when the paperwork is right. For a small exporter shipping to an unfamiliar market, that shift is the difference between a manageable risk and a gamble.

From the guide to the document
Your proforma with these details, ready as a PDF.
| Party | Role |
|---|---|
| Applicant | The buyer, who asks their bank to issue the credit — usually on the basis of your proforma invoice |
| Issuing bank | The buyer’s bank; it takes on the obligation to pay against compliant documents |
| Advising bank | A bank in your country that authenticates the credit and passes it to you |
| Confirming bank | A bank that adds its own undertaking, so you are no longer relying on a bank in the buyer’s country |
| Beneficiary | You, the exporter |
| Nominated bank | The bank authorised to receive and examine your documents and to pay, accept or negotiate |
Nearly all credits are issued subject to UCP 600, the ICC’s Uniform Customs and Practice for Documentary Credits. ISBP 745 is the companion publication that describes how banks actually examine documents in practice — worth its cost if you ship under credits regularly.
Read it as a list of things you must be able to do. If any line is outside your control, ask for an amendment immediately — amendments are cheap before production and painful afterwards.
| Document | What banks look for |
|---|---|
| Commercial invoice | Issued by the beneficiary, addressed to the applicant, same currency as the credit, goods description corresponding to the credit, amount not exceeding the credit |
| Transport document (B/L, air waybill, CMR, forwarder’s receipt) | Correct type, consignee and notify exactly as instructed, on-board notation where a marine bill of lading is required, freight prepaid or collect per the terms, full set of originals when called for |
| Packing list | Package count, marks and numbers, gross and net weights consistent with the transport document |
| Insurance document | Required under CIF and CIP, in the credit currency, cover at least 110% of the invoice value unless stated otherwise, effective no later than the shipment date |
| Certificate of origin | Issuer as specified — often a chamber of commerce; consistent with the invoice and, where required, legalised |
| Inspection or pre-shipment certificate | Issued by the named body; check who appoints and pays for the inspection |
| Bill of exchange (draft) | Drawn on the party the credit names, for the right tenor |
Details on each of these are in the export documents checklist.
A large share of first presentations contain at least one discrepancy. The recurring ones are mundane:
If the bank finds a discrepancy it must notify you once, stating every discrepancy, within the five-banking-day window. You can then correct and re-present if there is time, ask the applicant to waive the discrepancy, or fall back to a documentary collection. None of those is as good as presenting clean documents the first time.
Expect issuance and advising fees, a confirmation fee if you ask for one, document examination fees, amendment fees and courier charges. Together they typically run to a low single-digit percentage of the shipment value, higher for small shipments and for issuing banks in higher-risk jurisdictions. Under a usance credit you may be able to discount the accepted draft and receive funds early, at a cost.
Use a credit when the amount is large relative to your cash flow, the buyer is new, the country carries transfer risk, or local rules require it. For small repeat orders with a trusted buyer, the fees and the administrative load rarely justify it.
| Method | Security for the exporter | Typical use |
|---|---|---|
| Advance payment | Highest | Samples, small orders, new buyers |
| Deposit plus balance before shipment | High | Made-to-order goods; 30/70 is a common split |
| Confirmed irrevocable credit | High | Large shipments, higher-risk markets |
| Unconfirmed credit | Medium — you carry issuing-bank and country risk | Established corridors, sound banks |
| Documents against payment (D/P) | Medium — you keep control of the goods, but the buyer can walk away | Repeat buyers, shorter routes |
| Documents against acceptance (D/A) | Low | Long relationships, or with credit insurance |
| Open account | Lowest | Trusted long-term buyers; consider credit insurance |
Because the credit is written from your proforma, state on it: the payment method in full (“Irrevocable letter of credit at sight, confirmed by a first-class bank in the seller’s country, available with any bank by negotiation”), the documents you will present, the shipment period counted from the date the credit is advised, the ports of loading and discharge, whether partial shipment and transhipment must be allowed, the tolerance you need, and who bears which bank charges. Ten lines on the proforma prevent an amendment cycle later.

General information for exporters, not banking or legal advice. Your credit is governed by its own terms, by UCP 600 where it is incorporated, and by applicable law. Ask your bank’s trade finance desk to review any credit before you produce goods against it.
