B2B International Payment Methods: Types, Comparisons, and How to Choose

Learning > Trade Payments & Finance
When your business buys from or sells to international counterparties, how you move money matters is important. The payment method you select affects transaction costs, cash flow, security, settlement speed, compliance, and supplier relationships. Whether you're paying overseas suppliers, collecting payments from international clients, or managing global operations, understanding the available options can help reduce risk and improve efficiency.
 
This guide covers every major B2B international payment method, explains who each one is designed for, and gives you a clear framework for choosing the right option based on your transaction size, counterparty relationship, and risk tolerance.

What Are B2B International Payments?

B2B international payments refer to cross-border transactions between businesses located in different countries. These payments may be used for:
  • Paying overseas suppliers and manufacturers
  • Purchasing inventory or raw materials
  • Collecting payments from foreign customers
​Unlike domestic payments, international transactions involve additional considerations such as currency conversion, foreign exchange (FX) fees, banking regulations, compliance requirements, and payment network infrastructure.
 
The core tension in any cross-border B2B transaction is this: the seller wants payment before shipping; the buyer wants goods before paying. Every payment method in this guide sits somewhere on that spectrum, balancing protection, cost, and speed differently.

1. Bank Telegraphic Transfer (TT)

Bank Telegraphic Transfer (TT) are among the most widely used methods for cross-border B2B payments. Most international bank transfers are processed through the SWIFT network, which connects thousands of financial institutions worldwide.
 
What it is: An electronic transfer of funds between banks using the SWIFT network (global) or SEPA (within Europe). The most widely used method for large B2B transactions.
 
How it works: The payer's bank sends a payment instruction through the SWIFT network to the beneficiary's bank. Correspondent banks may act as intermediaries if the two banks don't have a direct relationship.
 
Typical cost: $25–$50 per transfer in bank fees, plus a foreign exchange (FX) markup of 1–4% depending on the bank and currency pair.
 
Settlement time: 1-5 business days, depending on the currency corridor and the number of correspondent banks involved.
 
Best for:
  • Large, one-time or recurring transactions
  • Established trading relationships where payment terms are agreed upfront
Key risks:
  • Irrevocable once sent - errors are difficult and slow to recover
  • Expensive for frequent, smaller payments
  • Subject to correspondent bank delays and compliance holds
  • FX markup varies significantly between banks

2. Letters of Credit (LC)

What it is: A guarantee issued by the buyer's bank that payment will be made to the seller, provided the seller presents documents that comply exactly with the terms specified in the LC (such as shipping documents, certificates of origin, or inspection reports).

How it works: The buyer applies for an LC from their bank (the issuing bank). The issuing bank sends the LC to a bank in the seller's country (the advising or confirming bank). The seller ships the goods and presents the required documents. If the documents comply, the bank pays - regardless of whether the buyer has funds.
 
Typical cost: 0.5–3% of the transaction value in bank fees, plus document preparation costs. A confirmed LC (where the seller's local bank also guarantees payment) costs more.
 
Settlement time: 5–30 days, depending on document complexity and courier time.
 
Best for:
  • New trading relationships with limited trust
  • High-value transactions in markets with political or economic risk
  • Commodity trade (steel, grain, oil) where document compliance is standard practice
  • Regulated industries requiring proof of shipment or inspection
Key risks:
  • Strict document compliance - even minor discrepancies can lead to rejection
  • Slow and paperwork-intensive
  • Does not protect against quality issues - only verifies that documents comply, not that goods are as described
  • Expensive relative to other methods

3. Documentary Collections (D/C)

What it is: A process where the seller's bank sends shipping documents to the buyer's bank, which releases those documents - allowing the buyer to take possession of goods - only upon payment (Documents against Payment, or D/P) or acceptance of a payment obligation (Documents against Acceptance, or D/A).

How it works: The seller ships the goods and gives the documents to their bank. The seller's bank sends these to the buyer's bank with instructions. The buyer's bank releases the documents only when payment is made (D/P) or a bill of exchange is accepted (D/A).
 
Typical cost: 0.1–0.5% of transaction value — significantly cheaper than an LC.
 
Settlement time: Varies; D/P collections settle at sight. D/A collections defer payment to an agreed future date.
 
Best for:
  • Established but not fully trusted relationships
  • Markets where full LCs are considered excessive overhead
  • Transactions where the seller is comfortable that the buyer will not abandon the goods
Key risks:
  • Banks act as intermediaries only - they do not guarantee payment
  • Offers less protection than an LC

4. Open Account

What it is: The seller ships goods and invoices the buyer, who pays at an agreed future date (net 30, 60, or 90 days). No bank intermediary is involved.

How it works: After goods are shipped and received, the buyer settles the invoice by the agreed due date via wire transfer, ACH, or another payment method.
 
Typical cost: No direct transaction fee (payment method costs apply separately). However, the seller bears the cost of financing the receivable during the credit period.
 
Settlement time: Per agreed payment terms - 30 to 120 days after shipment or invoice date.
 
Best for:
  • Long-established relationships with strong mutual trust
  • Markets with reliable legal enforcement of contracts
  • Buyers with strong credit ratings
Key risks:
  • Maximum risk for the seller - goods have left, payment is not guaranteed
  • Buyer insolvency or default leaves the seller with little recourse
  • Creates working capital pressure on the seller
  • Legal enforcement across borders is slow and expensive

5. Fintech Payment Platforms

What it is: Technology-first platforms that enable international business payments faster and more cheaply than traditional banks by aggregating liquidity and holding local currency accounts.

How it works: Businesses hold balances in multiple currencies within the platform. When paying a foreign supplier, the platform uses its local accounts on each side to settle domestically in many corridors, avoiding SWIFT entirely.
 
Typical cost: 0.4–1.5% FX margin (vs. 2–4% at banks), with flat transfer fees of $0–$15 depending on the corridor and platform.
 
Settlement time: Minutes to 1–2 business days on most major currency corridors.
 
Best for:
  • Frequent, mid-size transactions
  • Businesses paying suppliers or contractors in multiple countries
  • Startups and SMEs that can't justify bank treasury products
Key risks:
  • Not regulated as banks in most jurisdictions
  • Transaction size limits may apply on some corridors
  • Limited country coverage compared to SWIFT
  • Customer support quality varies across platforms

6. Escrow Services

What it is: A neutral third party holds the buyer's payment until both parties confirm that agreed conditions have been met (delivery, inspection, acceptance), then releases funds to the seller.

How it works: The buyer deposits funds with the escrow provider at deal initiation. The seller ships or delivers. The buyer inspects and confirms receipt (or disputes within an agreed window). The escrow provider releases funds to the seller.
 
Typical cost: 0.5–1.25% of transaction value for most commercial escrow providers.
 
Settlement time: Days to weeks, depending on the inspection and acceptance period agreed between parties.
 
Best for:
  • One-off, high-value transactions with a new counterparty
  • New business relationships
Key risks:
  • Adds friction to the transaction timeline
  • Dispute resolution processes vary by provider and can be slow
  • Not suitable for commodity trade with regular delivery schedules

How to Choose the Right B2B International Payment Method

Choosing the best international payment solution depends on several factors.
 
1. Transaction Value
Large transactions often justify more secure payment methods such as:
  • Bank Telegraphic Transfer (TT)
  • Letters of Credit
  • Escrow arrangements
2. Relationship with the Counterparty
Trust level is one of the most important considerations.
 
For new relationships:
  • Letter of Credit
  • Escrow
  • Partial advance payment
For trusted relationships:
  • Open account terms
  • Bank Telegraphic Transfer (TT)
  • Local bank transfers
3. Cost Sensitivity
Businesses focused on reducing payment costs should evaluate:
  • Foreign exchange fees
  • Transfer charges
  • Intermediary bank fees
  • Platform subscription costs
  • Document preparation costs for LCs and collections
  • Insurance or guarantee fees
4. Speed Requirements
When quick settlement is required:
  • Bank Telegraphic Transfer (TT)
  • Fintech payment platforms
For non-urgent transactions:
  • LC
  • Escrow
5. Risk Tolerance
Higher-risk markets and new trading relationships typically require stronger payment protections.
Recommended options include:
  • Letters of Credit
  • Escrow services
  • Advance payments

Some markets introduce risk that changes which method is appropriate:

  • High political or currency risk: Use LCs with confirmation from a bank in a stable jurisdiction. Consider pricing in USD or EUR.
  • Strong legal and banking systems: Open account or wire transfers are safe and efficient.
  • Emerging markets with good banking infrastructure: Documentary collections or confirmed LCs for first deals; fintech platforms for ongoing payments.

Quick-Reference Decision Framework

Frequently Asked Questions

What is the safest international B2B payment method?
For a seller, a confirmed Letter of Credit is the safest - payment is guaranteed by the bank as long as documents comply. For a buyer, escrow offers the most protection, as funds are only released upon confirmed delivery.

What is the cheapest international B2B payment method?
Open account has no direct payment cost, but the risk and working capital burden can be significant. Among methods with some level of protection, fintech platforms offer the best cost-to-security ratio for mid-size transactions.
 
What is the fastest international B2B payment method?
Fintech platforms settle in minutes to hours on major currency corridors. Bank Telegraphic Transfer (TT) takes 1–5 days.
 
What is the difference between a Letter of Credit and a Documentary Collection?
Both use banks as intermediaries and require shipping documents. The key difference: with an LC, the bank guarantees payment if documents comply. With a documentary collection, the bank only acts as an intermediary - it does not guarantee payment. This makes LCs more secure but more expensive.

Key Takeaways

  • There is no single best B2B international payment method - the right choice depends on relationship maturity, transaction size, country risk, speed requirements, and cost tolerance.
  • Letters of Credit offer the most protection for sellers in high-risk or new relationships but are slow and expensive.
  • Fintech platforms have significantly disrupted bank wires for mid-size, frequent transactions - offering lower FX margins and faster settlement.
  • Open account dominates established trade relationships in developed markets but exposes sellers to significant credit risk.
  • Always calculate total transaction cost - not just fees - when comparing payment methods. FX margin can be the largest hidden cost.
