Payment Methods in International Trade: A Risk Comparison

Cash in advance, open account, documentary collection and letters of credit: compare the risks of international trade payment methods.

In an international sale, the most important question is often “How and when will I get paid?” The exporter wants payment before the goods leave; the importer does not want to pay before seeing the goods. This guide explains the payment methods used in international trade—cash in advance, open account, documentary collection (cash against documents and documents against acceptance) and letters of credit—and compares their risks.

Why payment methods in international trade matter

The payment method shapes your cash flow, your credit risk, your bank charges and even your negotiating position. The same product sold at the same price carries a completely different risk depending on how it is paid for.

When choosing a payment method, ask:

  • How well do I know this buyer, and how long have we worked together?
  • Is there political, economic or transfer risk in the buyer’s country?
  • How large is this deal relative to my business?
  • What payment terms do competitors offer in this market?
  • Who will pay the bank charges, and in what proportion?

Payment terms and delivery terms (Incoterms) are separate questions, but they should be decided together. In document-based methods, for example, who controls the transport document depends on the delivery terms. Our Incoterms selector can help you settle the delivery side.

Cash in advance

The buyer pays all or part of the price before the goods are shipped, usually by bank transfer (SWIFT).

  • For the exporter: The safest method. Nothing ships until payment arrives.
  • For the importer: The riskiest method. The buyer carries the full risk of goods never arriving, arriving late or not matching the order.
  • Typical use: First deals, small orders, made-to-order products and buyers seen as high risk.

A common compromise is partial prepayment: part of the price on order, the rest before shipment or against documents.

Open account

The exporter ships the goods and sends the documents directly to the buyer, who pays later on the agreed terms.

  • For the exporter: The riskiest method. Once the goods and documents reach the buyer, the exporter holds no security.
  • For the importer: The most favourable method; the buyer can inspect, and even sell, the goods before paying.
  • Typical use: Long, trusted trading relationships, intra-group sales and highly competitive markets.

If you sell on open account, tools such as export credit insurance, bank guarantees or receivables finance (factoring) can reduce part of the risk.

Cash against documents (CAD / D/P)

Under cash against documents, also called documents against payment, the exporter ships the goods and then sends the shipping documents, including the transport document, through its own bank to the buyer’s bank. The buyer’s bank releases the documents only once the buyer pays. These transactions are usually handled under the ICC Uniform Rules for Collections (URC 522).

  • For the exporter: Safer than open account, because documents are not released without payment. But the banks give no payment undertaking: if the buyer never takes up the documents, the goods sit at destination, and the exporter may face the cost of returning, storing or reselling them.
  • For the importer: No payment until documents prove shipment, but payment comes before the goods can be physically inspected.
  • Key point: The method only works if the transport document controls delivery of the goods. At sea, an original bill of lading made out “to order” gives that control. An air waybill or a CMR note is normally not a document of title, so the consignee may be able to collect the goods without them. In those cases cash against documents offers much weaker protection.

That is why, for sea freight shipments, how the bill of lading is made out (to order, to a named consignee, etc.) directly affects payment security.

Documents against acceptance (D/A)

Documents against acceptance works much like cash against documents, except that the buyer receives the documents by accepting a time draft (bill of exchange) rather than by paying. The buyer collects the goods and pays when the draft falls due.

  • For the exporter: Riskier than cash against documents. Once the goods pass to the buyer, all the exporter holds is an accepted draft. A draft is a legal claim, but collecting it depends on legal processes in the buyer’s country.
  • For the importer: Provides deferred payment; the buyer can sell the goods before paying.
  • Extra security: In some cases the buyer’s bank can add its guarantee to the draft (an aval), which significantly reduces the risk.

Letter of credit (L/C)

Under a letter of credit, the buyer’s bank (the issuing bank) undertakes to pay the exporter if documents complying with the credit’s terms are presented. Letters of credit are usually subject to the ICC’s UCP 600 rules.

  • For the exporter: Payment risk moves from the buyer to the bank. If a bank in the exporter’s country also confirms the credit, the risk of the issuing bank and its country is largely removed too.
  • For the importer: Payment is made only when documents showing that the goods were shipped as agreed are presented.
  • Watch out for: Banks deal in documents, not goods. Even a small discrepancy in the documents can delay or block payment. Letters of credit also cost more in bank charges than other methods.

Risk comparison: which is safer, and for whom?

From the exporter’s point of view, the general order from safest to riskiest is:

  1. Cash in advance: Lowest risk for the exporter, highest for the importer.
  2. Letter of credit (especially confirmed): Balanced for both sides; payment is bank-backed as long as the documents comply.
  3. Cash against documents: No bank payment undertaking, but documents are not released without payment.
  4. Documents against acceptance: Goods pass to the buyer before payment; the exporter holds only an accepted draft.
  5. Open account: Highest risk for the exporter, lowest for the importer.

On cost, the order usually reverses: a letter of credit involves the most bank charges and paperwork, while open account is the simplest and cheapest. The right choice depends on your relationship with the buyer, country risk and the competitive environment.

No payment method covers loss of or damage to the goods in transit. Protecting the goods themselves is a separate matter for cargo insurance.

Frequently asked questions

What is the main difference between cash against documents and a letter of credit?

With a letter of credit, the bank undertakes to pay against compliant documents. With cash against documents, the banks only handle the documents; if the buyer does not pay, the bank has no obligation to pay.

Which payment method should I use with a new buyer?

Starting with cash in advance, partial prepayment or a letter of credit is generally advisable. As trust builds, you can move to documentary collection or open account.

Is cash against documents safe for air freight?

Less so. Because an air waybill is normally not a document of title, the consignee may collect the goods without taking up the documents from the bank. Options such as naming the bank as consignee on the AWB can be discussed with your bank.

What happens if the buyer does not pay under documents against acceptance?

The exporter can take legal action in the buyer’s country based on the accepted draft. Since that can be slow and costly, it is better to reduce the risk upfront with insurance or a bank aval.
