How to Pay Your International Suppliers and Vendors

To pay your international suppliers and vendors, choose a payment method that fits their country, currency and invoice size - usually a SWIFT wire, a local bank transfer through a payment provider, a card or a stablecoin payout. Then verify their bank details, agree on currency and fees, approve the payment internally and reconcile it against the invoice.

The method matters more than most businesses expect. It decides how much your vendor actually receives, how long they wait, who absorbs currency swings, and how much manual work your finance team carries every month. Below, we compare each option, walk through a safe six-step process, and show how to scale once you're paying suppliers in several countries.

What is the best way to pay international suppliers and vendors?

There is no single best way. SWIFT wires suit large, one-off invoices because almost any bank can receive them. Local bank transfers through a payment provider are usually cheaper and faster for recurring vendor payments. For suppliers in markets with limited banking or dollar access, stablecoin payouts can work well, provided the supplier agrees.

Speeds and costs vary by provider, country pair, amount and cut-off times. Treat these as general ranges and confirm with your provider.

6 ways to pay overseas suppliers

1. International wire transfer (SWIFT)

A wire moves money between banks over the SWIFT network, often passing through one or more correspondent banks. Nearly every supplier can receive one, which makes it the default for large payments.

The catch is cost and predictability. Intermediary banks may deduct fees in transit, so your vendor can receive less than the invoice amount, and banks often add a markup to the exchange rate. Agree in advance who pays charges using the SWIFT codes OUR (you pay), SHA (shared) or BEN (the supplier pays).

2. Local bank transfers through a payment provider

Payment providers with accounts in many countries can pay your supplier over domestic rails - SEPA in the eurozone, Faster Payments in the UK or Pix in Brazil, for example. Your vendor receives a local transfer, usually without intermediary deductions. Some providers also pay into mobile money wallets, which are widely used in parts of Africa and Asia.

3. Multi-currency accounts

A multi-currency account lets you hold several currencies, convert when rates suit you and pay suppliers from the matching balance. It works best if you also earn foreign revenue, because you can pay euro vendors with euro income instead of converting twice. TransFi's BizPay Pro, for instance, lets businesses send, receive and manage funds from one account, with fiat-to-stablecoin conversion built in.

4. Credit cards and virtual cards

Some vendors accept cards directly, and some platforms charge your card and pay the supplier by bank transfer. Cards can extend your cash cycle, but percentage-based fees make them costly for large invoices. Virtual cards add control through single-use numbers and spending limits.

5. Stablecoin payments

Stablecoins such as USDC and USDT are digital tokens designed to hold a steady value against a fiat currency, usually the US dollar. They settle on a blockchain in minutes, including weekends. For suppliers in countries where dollars are hard to obtain, receiving digital dollars, or having them converted to local currency on arrival, can beat waiting on a chain of correspondent banks.

There are caveats. Stablecoin rules vary by country and are still evolving, your supplier must agree to the method, and you need a provider that handles conversion and compliance screening. TransFi supports both stablecoin and local-currency payouts, so vendors who prefer not to hold digital assets can still be paid in fiat.

6. Letters of credit

A letter of credit is a bank's commitment to pay your supplier once they present shipping documents that match agreed terms. It protects both sides on large orders with new partners, but it is slow, paperwork-heavy and carries bank fees. Most long-term relationships eventually move to open-account terms, where the supplier ships first and you pay against the invoice.

How to pay an international supplier in 6 steps

1. Collect and verify vendor details. You'll typically need the supplier's legal name and address, bank name, account number or IBAN, SWIFT/BIC code and payment currency. Some countries require extra fields, such as a purpose code or tax ID.
2. Screen the supplier. Check them against sanctions lists and confirm the business is real. Regulated payment providers run these know-your-business (KYB) checks during onboarding.
3. Agree on currency and fees. Decide whether you'll pay in your currency or theirs, and who covers transfer charges. Write both into the purchase order or contract.
4. Match and approve the invoice. Check it against the purchase order and what was delivered, then have a second person approve the payment.
5. Convert and send. Compare your quoted rate with the mid-market rate to see the real markup. Use a forward contract if you need to fix a rate for a future payment.
6. Track and reconcile. Share the payment reference with the supplier, confirm receipt and record the payment and exchange rate in your accounting system.

How much does it cost to pay a supplier abroad?

The total cost of paying a vendor overseas is the sending fee, plus any intermediary or receiving-bank deductions, plus the exchange-rate markup. The markup is the least visible part, because it is built into the rate rather than listed as a fee.

Costs are high enough that the G20 has set a target: the global average cost of a retail cross-border payment (under $100,000) should not exceed 1% by the end of 2027. In the Financial Stability Board's 2024 survey of payment providers, B2B payments by micro, small and medium-sized businesses averaged 1.6% of the payment value, according to the Federal Reserve Bank of Atlanta.

To keep your own costs down:

• Ask each provider how much your supplier will receive in their currency, not just what the fee is.
• Pay recurring suppliers over local rails rather than SWIFT where you can.
• Hold the foreign currency you earn and pay vendors from it, using multi-currency tools such as TransFi's Corporate Treasury solution.
• Consider paying in the supplier's currency, since vendors quoting in a foreign currency may add a buffer to cover exchange-rate swings.

How to keep vendor payments safe and compliant

Supplier payments are a common target for invoice fraud, often through business email compromise: a criminal impersonates a vendor and sends "updated" bank details. A few simple controls reduce the risk:

• Confirm any change to bank details by calling the supplier on a number you already hold, never one from the email.
• Use maker-checker approval, so the person who sets up a payment can't also release it.
• Send a small test payment to new beneficiaries before large transfers.
• Keep an audit trail of approvals, exchange rates and confirmations.

Your payment provider should also screen transactions against sanctions lists, monitor for suspicious activity and, for digital-asset transfers, follow the FATF travel rule.

How TransFi helps you pay suppliers in multiple countries

Before you start, compare TransFi's supported countries and payment methods with your supplier list.

Final thoughts

Knowing how to pay your international suppliers and vendors well comes down to three decisions: the right rail for each supplier, a clear view of the real cost including FX, and controls that keep every payment verified and traceable. Start with the method your supplier can receive easily, compare what they will actually receive across providers, and tighten approvals before your volumes grow.

Frequently asked questions

1. What is the cheapest way to pay international suppliers?

For recurring payments, local bank transfers through a payment provider usually cost less than SWIFT wires because they avoid intermediary deductions. Compare the amount your supplier receives, not just the fee.

2. Should I pay suppliers in my currency or theirs?

Paying in their currency shifts exchange-rate risk to you but can win better prices, since suppliers quoting in yours may add a buffer. Paying in yours keeps costs predictable.

3. Do suppliers need a crypto wallet to receive stablecoin payments?

Not necessarily. Some providers, including TransFi, can pay suppliers in local currency instead, so they never have to hold digital assets.

4. How long does it take to pay an international supplier?

Local bank transfers are often completed the same or next day, while SWIFT payments can take from the same day to several business days. Stablecoin payments can settle on-chain within minutes, plus any required conversion time.

5. How can businesses make international supplier payments safer?

Businesses should verify supplier details, screen vendors, use maker-checker approvals, confirm any bank-detail changes independently, and maintain an audit trail of payments and confirmations.
