Letters of Credit for Small Importers and Exporters: How to Get Paid When Your Trading Partner Is a Stranger

You found a supplier overseas who can make your product for 40 percent less than your domestic source. Or a buyer on another continent just placed the biggest order your small shop has ever seen. Either way, the same question keeps you up at night: who moves first? If you wire the money before the goods ship, you may never see either. If you ship the goods before payment arrives, you may never get paid. A letter of credit exists to break exactly that deadlock — a bank stands between the two sides and promises payment, but only against documents proving the goods shipped as agreed.

This guide explains how letters of credit work in plain language, which flavor fits your situation, what they cost, and the document mistakes that cause most first-time presentations to be rejected.

The Payment-Method Spectrum: Where Letters of Credit Fit​

Every cross-border deal sits somewhere on a risk spectrum. Understanding the full menu helps you see why a letter of credit is often the sensible middle ground for a first deal with an unknown partner.

• Cash in advance. The exporter is fully protected; the importer takes all the risk, plus the cash-flow pain of paying before shipment. Many buyers will simply walk away to a competitor offering better terms.
• Letter of credit. The importer's bank commits to pay the exporter once specified shipping documents are presented. Both sides get meaningful protection.
• Documentary collection. Banks pass documents and collect payment but verify nothing and guarantee nothing. Cheaper than a letter of credit, but the exporter has little recourse if the importer refuses to pay. Best reserved for established relationships in stable markets.
• Open account. Goods ship first; payment follows in 30, 60, or 90 days. Great for the importer's cash flow, and the highest risk for the exporter.
• Consignment. The exporter gets paid only after a foreign distributor sells the goods to the end customer. Maximum risk for the exporter.

The U.S. International Trade Administration's Trade Finance Guide frames the trade-off plainly: insist on cash in advance for every deal and you lose sales to competitors; ship on open account to a stranger and you gamble the whole shipment. A letter of credit is the compromise instrument — more expensive than open terms, far safer than trust alone.

How a Letter of Credit Actually Works​

Strip away the jargon and the mechanics are straightforward. There are two commercial parties and at least two banks:

• Applicant: the importer (buyer) who asks its bank to open the credit.
• Beneficiary: the exporter (seller) who gets paid under the credit.
• Issuing bank: the importer's bank, which opens the credit and makes the payment promise.
• Advising bank: usually the exporter's bank, which authenticates the credit and forwards it to the exporter.
• Nominated bank: the bank authorized to examine documents and pay — often the same as the advising bank.
• Confirming bank: a second bank, typically in the exporter's country, that adds its own independent payment promise on top of the issuing bank's.

A typical transaction runs in eight steps:

1. The importer applies to its bank, which evaluates the importer's creditworthiness and opens the credit in favor of the exporter.
2. The issuing bank transmits the credit to the exporter's bank.
3. The exporter's bank authenticates it and advises the exporter.
4. The exporter ships the goods through a freight forwarder.
5. The exporter (or forwarder) presents the required documents — commercial invoice, bill of lading, packing list, and whatever else the credit specifies — to the bank.
6. The bank examines the documents for compliance and collects payment from the issuing bank.
7. The issuing bank debits the importer's account.
8. The issuing bank releases the documents so the importer can claim the goods from the carrier and clear customs.

Two principles govern everything else. First, the credit is a separate contract from the sales contract — banks deal in documents only, not goods. The bank does not inspect your shipment, judge its quality, or care whether anyone performed the underlying deal. Second, payment is conditioned on documents that strictly comply with the credit's terms. Get the paperwork exactly right and the bank must pay even if the buyer has gone silent. Get one detail wrong and the bank may refuse — which is why the discrepancy section below matters more than any other part of this guide.

Unless the credit says otherwise, it is always irrevocable: no party can amend or cancel it without the agreement of the importer, the banks, and the exporter alike.

The Flavors That Matter to Small Businesses​

Sight vs. Usance (Deferred Payment) Credits​

A sight credit pays the exporter as soon as compliant documents are presented and approved — fast cash for the seller. A usance (deferred payment) credit pays on a specified future date, such as 60 or 90 days after the bill of lading date. Usance credits give the importer time to receive, sell, or process the goods before the money leaves the account, and effectively bundle financing into the payment method. Expect the exporter to price that waiting time into the deal.

Unconfirmed vs. Confirmed Credits​

With an unconfirmed credit, only the issuing bank (in the importer's country) promises to pay. The exporter waits until documents reach that foreign bank, and bears both the bank's credit risk and the importing country's political risk — upheaval, currency controls, or a banking crisis can all strand payment.

With a confirmed credit, a second bank — normally in the exporter's own country — adds its own independent promise to pay against compliant documents. The exporter presents documents locally and gets paid locally, without waiting on a bank halfway around the world. Consider confirmation when you doubt the foreign bank's standing, when the importing country carries meaningful political or currency risk, or when the importer wants extended payment terms. Confirmation also makes it easier to get financing against the credit before the due date. It costs extra, but for a first deal in a volatile market it is often the cheapest insurance you will ever buy.

Standby Letters of Credit​

A commercial (documentary) credit is the expected way you get paid: present shipping documents, receive money. A standby credit works the other way around — it sits unused unless something goes wrong. If the importer fails to pay an invoice, the exporter draws on the standby by presenting a simple demand statement. Standbys also back bid bonds, performance bonds, and advance-payment guarantees, and exporters post them in favor of importers just as often as the reverse.

One technical note that saves real confusion: documentary credits are governed by the ICC's UCP 600 rules, while standbys are frequently issued under ISP98, a separate ICC rule set written specifically for standby practice. Either rule set can govern a standby, but the instrument should say which one applies — check before you sign.

Transferable and Revolving Credits​

Two special forms come up often enough to know by name. A transferable credit lets the original beneficiary transfer the payment obligation to one or more second beneficiaries — useful for intermediaries and trading houses that never take physical possession. A revolving credit automatically restores itself to its original amount each time it is drawn down, which suits a steady stream of repeat shipments better than opening a fresh credit every month.

What a Letter of Credit Costs​

Letters of credit are not free, and the cost shapes when they make sense. Typical pricing includes:

• Issuance fee: commonly around 0.5 to 2 percent of the credit amount, paid by the importer to its bank for opening the credit.
• Confirmation fee: charged for the second bank's independent promise, varying with the issuing bank's and country's risk.
• Amendment fees: every change after issuance — a new shipment date, a corrected goods description — costs money, so negotiate terms carefully before the credit is opened.
• Examination, negotiation, and discrepancy fees: banks charge for checking documents, and discrepant presentations often attract an extra handling fee on top of the delay they cause.

For small shipments, fixed minimum fees can make a credit uneconomical — a few hundred dollars of bank charges on a 3,000-dollar order changes the math. That is one reason small exporters should know about government-backed help. The Small Business Administration's export finance programs can support standby letters of credit with collateral as low as 25 percent of the face value, far below what a bank would demand on its own. The SBA Export Working Capital Program (loans up to 5 million dollars, with a 0.25 percent upfront guaranty fee) and the Export-Import Bank's working capital guarantees help small firms finance the production and shipment periods that a credit does not cover. If your bank is an SBA or EXIM delegated lender, ask specifically about these programs — many small businesses never hear of them.

The Discrepancy Trap: Why Most First Presentations Get Rejected​

Here is the statistic every first-time user should know: trade-finance surveys routinely find that a majority of first presentations under letters of credit — often cited around 60 to 70 percent — contain at least one discrepancy. A discrepancy means the documents deviate in any way from what the credit demands, and any discrepancy gives the bank grounds to refuse payment.

This is not banks being difficult. Under strict-compliance examination, the bank compares paper to paper: the goods description on the invoice against the description in the credit, quantities and weights across the invoice, packing list, and bill of lading, dates against the shipment and expiry deadlines. The most common discrepancies are depressingly ordinary:

• The invoice describes the goods differently than the credit does — even slightly.
• Quantities, weights, or place names disagree between documents.
• Shipment happened after the latest shipment date, or documents were presented after the expiry date.
• Required documents are missing, unsigned, or submitted in the wrong number of copies.
• Freight or insurance terms (Incoterms) on the documents contradict the credit.

When documents are refused, the exporter does not automatically lose the money — the bank typically holds the documents and asks the importer whether to accept them despite the discrepancies. But the exporter has lost the bank's independent promise and is back to relying on the buyer's goodwill, plus delays, cable charges, and discrepancy fees. The Trade Finance Guide's advice is blunt: have documents prepared by trained professionals or outsource the job.

A Practical Checklist Before You Ship or Pay​

If You Are the Exporter​

1. Read the credit the day it arrives. Confirm the amount, currency, goods description, Incoterms, shipment and expiry dates, and the documents list match the sales contract. Anything you cannot produce exactly as described needs an amendment now, not at the port.
2. Request amendments early. Corrections take days and cost fees, but they are cheap compared with a refused presentation.
3. Calendar three dates: the latest shipment date, the presentation deadline, and the credit's expiry. Missing any of them is fatal to the bank's promise.
4. Keep every document consistent. Use identical goods descriptions, quantities, weights, and place names across the invoice, packing list, bill of lading, and certificates. Copy-paste beats retyping.
5. Present early. Leave buffer time so a correctable problem can actually be corrected before expiry.

If You Are the Importer​

1. Specify documents precisely. Vague requirements invite vague documents. If you need an inspection certificate, say which inspector and which standard.
2. Align the credit with your Incoterms. A classic structural error is pairing a credit with EXW (Ex Works) terms: with no transport leg arranged by the seller, there is typically no transport document for the bank to examine, and the credit's machinery jams. FOB, CFR, and CIF map far more cleanly onto documentary credits.
3. Vet the advising and confirming banks. Your exporter will ask for a bank it trusts in its own country — agreeing upfront avoids amendment rounds.
4. Respond fast to discrepancy notices. If documents arrive with minor discrepancies and the goods are fine, waiving the discrepancies quickly keeps your shipment (and your supplier relationship) moving.

Track Every Dollar the Credit Touches​

A letter of credit generates a paper trail that your bookkeeping needs to capture: issuance and confirmation fees, amendment charges, discrepancy fees, freight and insurance line items that must reconcile against the invoice, and payment dates that rarely match the shipment month. Small importers routinely understate landed cost because the bank fees land in a different statement than the supplier invoice. Record credit-related bank charges against the shipment they belong to, reconcile the confirming bank's payout against your sales invoice as an exporter, and keep every amendment with the sales contract so an auditor — or a dispute two years later — finds one coherent file. If you want a system where those postings are explicit, reviewable text rather than clicks in a black box, the docs walk through plain-text double-entry patterns that fit trade transactions well.
