Why do payment methods matter in international trade?
In international trade, seller and buyer are separated by thousands of kilometers, different legislations, customs regulations, currencies and sometimes languages. Choosing the right payment method is the difference between a profitable operation and a total loss.
The International Chamber of Commerce (ICC) publishes the rules that standardize the main mechanisms: UCP 600 for letters of credit, URC 522 for documentary collections, ISP 98 for standby letters of credit, and URBPO 750 for Bank Payment Obligations.
This guide summarizes the 6 alternatives (5 traditional + digital BPO), risk level for seller and buyer, associated costs and when each is appropriate.
Risk axis: seller vs buyer
Risk is distributed inversely between seller and buyer according to the chosen payment method:
| Payment method | Seller risk | Buyer risk | Cost |
|---|---|---|---|
| Cash in advance | Minimum | Maximum | Low |
| Letter of Credit (L/C) | Low | Low | High (0.5–2%) |
| Documentary collection | Medium | Medium | Medium |
| Open account | Maximum | Minimum | Minimum |
| Consignment | Maximum | Minimum | Minimum |
| Digital BPO | Low | Low | Medium |
The 6 payment methods in detail
Cash in Advance
· Advance PaymentThe buyer pays the seller BEFORE the shipment of goods, fully or partially. It is the safest method for the seller but the riskiest for the buyer.
When to use:
Seller with little leverage against an unknown buyer. Custom or highly specialized products. Markets with high country risk.
Pros:
Zero non-payment risk for the seller. No complex bank costs. Immediate cash flow.
Cons:
Full non-delivery risk for the buyer. Buyer bears quality and timing risk. Hard to accept under competition.
Letter of Credit
· L/C — UCP 600A payment commitment from the issuing bank (buyer's) to the seller, guaranteed against presentation of conforming documents. Governed by ICC's UCP 600 rules.
When to use:
High-value operations. First transaction with a new client. High-risk markets. When both parties want to balance risk.
Pros:
Balanced risk: the bank assumes payment responsibility. Protection against country and commercial risk. Clear international rules (UCP 600).
Cons:
Significant bank costs (0.5-2% of value). Rigorous documentation: any discrepancy blocks payment. Administrative timelines.
Documentary Collection
· D/C — URC 522The seller sends documents to its bank, which forwards them to the buyer's bank. The buyer only receives documents against payment (D/P) or acceptance of bill (D/A). Governed by URC 522.
When to use:
Established but not fully trusted commercial relationship. Medium-sized operations. When seeking lower cost than letter of credit.
Pros:
Cheaper than letter of credit. Seller controls documents until payment. Clear ICC rules (URC 522).
Cons:
The bank does NOT guarantee payment like an L/C. If the buyer doesn't pay or accept, cargo may be stranded at destination. Intermediate country risk.
Open Account
· O/AThe seller ships the goods and documents directly to the buyer, who pays after receipt (typically 30, 60 or 90 days). The most common method between companies with established relationships.
When to use:
Buyers with excellent credit reputation. Long commercial relationships. Low-risk markets (EU, USA, Canada, Australia). Same-group subsidiaries.
Pros:
Minimum cost. Fast processes without bank paperwork. Strengthens commercial relationship. Allows financing the buyer.
Cons:
FULL non-payment risk for the seller. No bank guarantee. Requires credit insurance or factoring to mitigate.
Consignment
· ConsignmentThe seller ships the goods but retains ownership. The buyer pays only when reselling to end customers. Extreme variant of open account.
When to use:
Market testing for new products. Aggressive distribution strategies. When the seller has capital and wants to quickly conquer market.
Pros:
Allows penetration of new markets without barriers. Buyer takes no inventory risk. Useful for fashion or seasonal products.
Cons:
Maximum risk for the seller. Capital tied up in destination stock. Requires solid contract and cargo + credit insurance.
BPO (Bank Payment Obligation)
· URBPO 750Electronic form created by the ICC in 2013. Irrevocable commitment of the buyer's bank to pay the seller's bank when commercial data (not physical documents) matches electronically. URBPO 750 rules.
When to use:
Companies with advanced digital systems. Recurring operations with established partners. Digitalized supply chains (TSU - Trade Services Utility).
Pros:
Faster than letter of credit. No physical documents: 100% electronic. Lower costs than L/C. Reduces documentary errors.
Cons:
Still limited adoption (few companies and banks). Requires digital infrastructure. Still consolidating globally.
The ICC rules governing international payments
The International Chamber of Commerce (ICC) has published the most widely-used standardized trade rules since 1933. They are voluntarily adopted by banks, exporters and importers in over 175 countries.
In force since 2007. Regulates how letters of credit (L/C) operate worldwide. The de facto standard: virtually all international L/Cs are governed by UCP 600.
In force since 1996. Establishes responsibilities and procedures for documentary collection (D/P and D/A). Clear legal framework between remitting banks, presenters and commercial parties.
In force since 1998. Specifically regulates Standby Letters of Credit (SBLC), which work as performance guarantees. Differentiates between SBLC and commercial L/C.
In force since 2013. Governs the BPO, electronic alternative to the letter of credit. Allows payments based on electronic data instead of physical documents.
Allows electronic presentation of documents in letter of credit operations. Enables use of e-Bills of Lading and other digital documents.
Types of Letter of Credit
The letter of credit is the most important instrument. Several modalities exist depending on guarantee level, term and flexibility:
Irrevocable L/C
Cannot be modified or cancelled without the agreement of ALL parties. It is the standard form under UCP 600 — every L/C is deemed irrevocable unless stated otherwise.
Confirmed L/C
A second bank (typically in the seller's country) ADDS its payment guarantee to the issuing bank's commitment. Provides maximum security: two banks back the operation. Recommended when the issuing bank or buyer's country carry high risk.
Sight L/C
Payment is made immediately upon presentation of conforming documents at the bank. The most common modality for regular international trade operations.
Usance / Deferred L/C
Payment occurs at a term after document presentation (30, 60, 90, 180 days). Works as buyer financing with bank backing.
Standby Letter of Credit (SBLC) — ISP 98
Bank guarantee that is only executed if the buyer FAILS to fulfill their payment obligation. Works as insurance against default. Governed by ISP 98.
Revolving L/C
Automatically renews to cover multiple successive shipments without issuing a new L/C each time. Useful for recurring operations.
Transferable L/C
Allows the seller (beneficiary) to transfer all or part of the credit to a third party. Useful when the seller is an intermediary and needs to pay the actual producer.
Typical costs of a Letter of Credit
- • Issuance fee (buyer's bank): 0.125% – 0.5% per quarter
- • Confirmation fee (seller's bank): 0.1% – 1% per quarter
- • Payment / acceptance fee: 0.1% – 0.25%
- • Discrepancy fees: USD 50 – 150 per incident
- • SWIFT and mail: USD 30 – 100 per message
- • Estimated total: 0.5% – 2% of operation value
Decision tree: which payment method suits me?
Use this quick guide based on your operation's characteristics:
| Situación | Recomendación |
|---|---|
| New customer, first operation, high amount | Confirmed Letter of Credit (L/C) |
| Recurring customer with good history, low-risk market | Open account (with credit insurance) |
| Known customer, medium amount, cost-sensitive | Documentary collection D/P |
| Unknown customer, high-risk market | Cash in advance (full or 50%) or Confirmed L/C |
| Operation between same-group subsidiaries | Open account or consignment |
| Need to finance the buyer | Usance L/C or open account 60-90 days |
| Want to guarantee payment if buyer defaults | Standby L/C (SBLC) — ISP 98 |
| Companies with advanced digital platforms and recurring operations | BPO (URBPO 750) |
SWIFT: the network behind international payments
SWIFT (Society for Worldwide Interbank Financial Telecommunication) is the interbank messaging network connecting over 11,000 banks in 200+ countries. It is NOT a payment system itself: it's the infrastructure that allows banks to communicate payment instructions securely and in a standardized way.
A typical international transfer involves 2 to 4 banks: the originator's bank, one or two correspondent (intermediary) banks, and the beneficiary's bank. Each charges its fee, which can total USD 25 – 75 per operation, plus exchange rate differentials.
Key codes are: BIC/SWIFT (8-11 characters identifying the bank), IBAN (European format, 15-34 characters), and MT103 (commercial transfer), MT700 (L/C issuance) and MT760 (Standby) messages.
