International Trade Payment Methods: Wires, Letters of Credit and Security

In an international transaction, payment is where the seller's and buyer's interests collide hardest. The seller wants to be paid before shipping; the buyer wants the goods before paying. Every payment instrument in international trade exists to resolve that disagreement. This guide explains which one to use, when, and at what level of risk.

The principle: who carries the risk, and when

No payment method is inherently "safe." What exists is a risk scale running from one extreme to the other:

Negotiating payment terms means negotiating where your cursor sits on that scale. A buyer demanding open account on a first order is effectively asking you to finance their inventory.

The international bank wire

The most widely used method, especially for Asian purchases and first transactions.

How it is used in practice

The common structure combines a deposit at order and a balance at a defined milestone: before shipment, against presentation of documents, or against a copy of the bill of lading.

What to verify without exception

• The bank account is in the exact legal name of the invoicing company.
• The bank is located in the company's country.
• The banking details were not "updated" by email mid-negotiation — this is the most frequent fraud pattern. Confirm any change by phone, on a number you sourced yourself.

Strengths and limits

Simple, fast, inexpensive. But an executed wire is very hard to recover. That is why it should never cover 100% of the amount before shipment in a new relationship.

The documentary letter of credit

The buyer's bank undertakes to pay the seller if the seller presents documents that strictly comply with agreed terms.

Why it is powerful

The seller no longer depends on the buyer's goodwill, only on their own ability to produce compliant documents. The buyer, in turn, does not pay without evidence of shipment.

Why it is demanding

• Documentary compliance is strict. A date, a spelling or a divergent description creates a discrepancy that can suspend payment.
• Bank charges are real and are split between the parties.
• Timelines are longer and preparation demands discipline.

A letter of credit earns its keep above a certain amount, or when the parties barely know each other. Our guide to international trade documents is particularly relevant here, because documentary quality is what triggers payment.

Documentary collection

Here the bank provides no payment guarantee — it acts as intermediary for the release of documents.

• Documents against payment — the buyer gets the documents by paying.
• Documents against acceptance — the buyer gets the documents by accepting a time draft.

Cheaper than a letter of credit and safer than open account, but if the buyer refuses to take up the documents your cargo sits at destination without an owner. Reserve it for proven relationships, and preferably for destinations where you can react.

Escrow and marketplace protection

For modest amounts, notably a first sourcing purchase, the assurance mechanisms offered by major B2B marketplaces act as escrow: funds are released to the supplier after a validated milestone.

Know the limits: protection conditions are specific, dispute windows are short, and cover often addresses receipt rather than fine product quality. Read the terms before relying on them.

Open account

You ship, and the buyer pays at maturity. This is the norm between established partners and in some distribution relationships, but it is supplier credit. Grant it only after several successful cycles, with a defined credit limit, and ideally trade credit insurance.

How the bill of lading secures payment

A negotiable ocean bill of lading is a document of title: whoever holds the originals controls release of the cargo. That mechanism sits at the heart of documentary payment.

In practice:

• Do not issue an express release before payment if payment is not guaranteed.
• Do not send the originals to the buyer before the agreed payment milestone.
• Check consignee and notify party names — an error can complicate release. See the bill of lading explained.

Currency and FX exposure

Invoicing or paying in a foreign currency introduces a risk distinct from credit risk. Three approaches:

1. Invoice in your own currency and leave the exposure with the other party — simple, sometimes less competitive.
2. Accept the customer's currency and hedge with your bank.
3. Shorten payment timelines to reduce exposure.

For material amounts, talk to your bank before signing, not after.

The most common payment frauds

• Wire redirection via a compromised email account and changed banking details.
• Fake company with a recent website, unverifiable address and personal bank account.
• Phantom buyer asking you to ship before payment while promising huge volumes.
• Forged payment confirmations presented as proof of transfer.
• Overpayment followed by a request to refund part of it to a different account.

The most effective rule is also the simplest: verify through an independent channel. Our guide on vetting a wholesale supplier covers the method.

Choosing by situation

• First purchase from a new supplier, small amount — limited deposit plus balance against documents, or marketplace protection.
• Large amount, new relationship — letter of credit.
• Established relationship, regular flows — wire with deposit, possibly documentary collection later.
• Long-term partnership with solid history — open account within a credit limit.
• Exporting to a market where you cannot react quickly — favour documentary security over commercial flexibility.

Draft the payment clause properly

Many disputes start with a payment clause written in a single line. A usable clause specifies five things:

1. Amount and currency, unambiguously.
2. The schedule — what percentage, at which precise event (signature, production start, document presentation, arrival).
3. The trigger event, objectively defined: "against presentation of the bill of lading" is verifiable; "on shipment" is not.
4. Bank charges — who pays issuance, confirmation and correspondent fees.
5. Consequences of delay — interest, suspension of shipment, retention of original documents.

Coordinate payment, Incoterm and documents

These three decisions belong together. A concrete example: selling CIF destination port while accepting balance payment on arrival means financing both the freight and the goods for the entire voyage. Selling FOB Montreal with the balance payable against presentation of the bill of lading sharply limits your exposure instead.

One habit before every significant payment

Apply the rule of three confirmations before any material wire: the beneficiary name matches the invoice exactly, the banking details are identical to those received in the first exchange, and you have confirmed verbally with a known contact. Three minutes of checking sometimes protects tens of thousands of dollars.

Match the instrument to the shipment, not to habit

Review payment terms shipment by shipment rather than freezing them once. A supplier who has performed reliably for a year can reasonably be offered better terms; a new destination, an unusually large order or a market where enforcement is difficult justifies tightening them again. Payment terms are a risk instrument, and risk changes with every deal.

Keep a written trail of every term change

Payment disputes are almost always won or lost on written evidence. Whenever terms change — a revised deposit, an extended maturity, a partial shipment, a discount for early settlement — confirm it in writing and reference the order number. Verbal agreements made over a call or a messaging app are extremely difficult to enforce across borders, especially where currency conversion and bank charges create small discrepancies that later look like underpayment. A short confirmation email after every commercial conversation costs nothing and turns an informal understanding into something your bank, your insurer and, if it ever comes to it, an arbitrator can actually read.

FAQ

What is the safest payment method for a Canadian exporter?

A confirmed letter of credit offers the strongest protection, provided you can produce strictly compliant documents. For smaller amounts, a substantial deposit combined with document release tied to payment is usually more proportionate.

Can I pay a foreign supplier by credit card?

Sometimes, for small amounts or samples. It is not suited to volume orders, and conversion fees erode the benefit.

What if a supplier asks for a wire to a personal account?

Refuse. A personal account removes traceability of the company's obligation and severely weakens any recourse.

Does a letter of credit protect against non-conforming goods?

No. It guarantees payment against compliant documents, not product quality. That is why a pre-shipment inspection is sometimes added as a documentary condition.

Should I insure the cargo even when payment is secured?

Yes. Payment and physical risk are separate matters. See our guide on marine cargo insurance.

When should freight be paid?

It depends on the Incoterm and your agreement with the forwarder. Settle it at the same time as the goods payment so you do not discover charges at delivery.

Conclusion

The right payment method is not the most sophisticated one — it is the one that matches the amount at stake, the age of the relationship and your ability to react if something goes wrong. Start conservatively, document everything, and relax your terms only after several successful cycles.
