In short
What is the best way to pay an international vendor?
Use the rail that gives the vendor the required currency and net amount with acceptable timing, traceability, and risk. Compare a bank wire, an international or local-clearing payment, a payment platform, and stablecoin settlement where both parties can use it. Verify the beneficiary independently before releasing funds.
Start with the vendor’s required outcome
The first question is not “Which provider is cheapest?” It is “What must arrive?” Ask the vendor to state the invoice currency, the exact amount due, the due date, and whether bank charges may be deducted. SWIFT payment messages distinguish charge arrangements in which the beneficiary, ordering customer, or both sides bear processing charges. That means a payment can leave your account for the invoice amount while the vendor receives less. If the contract requires the full invoiced amount, make that an acceptance criterion for the quote.
Four practical ways to pay an overseas supplier
No row produces a universal winner. Use it to decide which quote to request for the actual corridor.
| Feature | Bank wireBank-to-bank | International or local clearingACH-adjacent | Payment platformProvider network | StablecoinOn-chain settlement |
|---|---|---|---|---|
| Good fit | Time-sensitive or high-value payment where bank traceability matters | Routine supplier payment on a supported corridor | Business wants one interface across several payout routes | Both parties already operate compatible wallets and agree the settlement asset |
| Cost question | Sender, intermediary, receiver, and FX costs | Provider fee, FX rate, and any receiving charge | Quoted fee, FX rate, and amount delivered | Conversion, network, custody, and off-ramp costs |
| Operational question | Which bank identifiers and intermediaries are required? | Is this corridor supported and what recipient data is mandatory? | Who holds funds and how are exceptions handled? | Which token contract, chain, wallet, and confirmation policy apply? |
| Main control | Independent beneficiary verification and dual approval | Validated recipient record and invoice reference | Role-based approval plus downloadable payment evidence | Allowlisted wallet, test transfer, and network verification |
Wire finality statement from the Federal Reserve; charge allocation from SWIFT. The other cells are a buyer-side evaluation framework, not provider promises.
Information to collect before you pay
Build the payee record from the contract and independently verified vendor instructions, not from fields guessed during payment entry.
Identify the legal payee
Record the contracting entity’s full legal name, registered or operating address, country, and the contact authorized to discuss payment. International ACH records carry information about the parties to a transaction.
Capture the destination account exactly
Ask for the account holder name, bank name and address, account number or IBAN where applicable, and SWIFT/BIC or the corridor’s local bank code. Use Glide’s /swift-code directory to inspect a BIC and /tools/iban-checker to validate an IBAN format, but confirm ownership with the vendor or its bank.
Lock the commercial instruction
Store the invoice number, purchase-order number, invoice currency, amount, due date, and the vendor’s charge preference. Put the invoice or purchase-order reference in the remittance field so the supplier can match the receipt without relying on a screenshot.
Document the approval
Keep the approver, verification evidence, quote, payment confirmation, and final status together. A payment record should make it possible to answer who approved the obligation, which instructions were used, what was sent, and what the provider reported afterward.
Compare total cost, not the headline fee
A usable quote has four numbers: the amount debited, the exchange rate, all visible fees, and the amount expected to reach the vendor. SWIFT’s research on cross-border payments notes that each bank in a correspondent chain can charge transaction fees and that charge treatment varies by market. A zero or low sender fee therefore does not prove a low total cost. If one quote converts currency and another delivers the invoice currency directly, compare both against the same required vendor receipt.
| Field | Record | Why it matters |
|---|---|---|
| Invoice obligation | Currency and exact amount due | Defines the outcome before provider economics |
| Amount debited | Your account currency and total debit | Captures the sender-side cash cost |
| FX | Quoted rate and conversion amount | Exposes cost that is embedded in the rate |
| Charges | Sender, shared, or beneficiary treatment | Shows who may absorb payment-chain fees |
| Expected receipt | Vendor currency and net amount | Tests whether the invoice will be fully settled |
| Delivery estimate | Provider estimate plus cut-off basis | Lets AP schedule approval before the due date |
| Evidence | Reference, tracking, or transaction hash | Supports inquiry and reconciliation |
SWIFT defines charge-bearer fields for debtor, creditor, or shared charges. The quote-sheet design is an operational recommendation.
Prevent duplicate payments and vendor-change fraud
The strongest controls sit between an invoice arriving and a payment being released.
Create one invoice identity
Normalize the vendor, invoice number, currency, and amount into a duplicate key. Stop entry when the same obligation already has a posted, pending, or approved payment. A different file name or forwarded email should not create a second payable.
Freeze changed details
If an email changes an account number, bank, wallet, currency, or payment procedure, do not update the payee and pay in the same action. The FBI specifically advises businesses to verify changes in account number or payment procedure with the requester.
Call a known contact
Use a telephone number from the contract, prior verified records, or the vendor’s independently located website. The FBI warns not to use the contact details supplied by the potential scammer. Record who confirmed the change and when.
Separate maker and approver
For meaningful amounts, the person who creates or changes the beneficiary should not be the only person who releases the payment. Give the approver the invoice, old and new details, verification record, and quote, not just a green button.
Reconcile the result
Match the provider confirmation and bank or wallet debit to the payable, then obtain vendor confirmation when the amount is material or the instructions changed. Keep an unresolved item open rather than entering a replacement payment immediately.
Where stablecoin settlement and Glide fit
Stablecoin settlement can remove some conventional-rail handoffs when a buyer and vendor already use the same asset and compatible network. It does not remove diligence. The BIS notes that the same named stablecoin on one chain is not inherently interoperable with that token on another chain. The FSB identifies operational, cyber, financial-integrity, issuer, and market risks around global stablecoin arrangements. Confirm the token contract, network, destination wallet, redemption path, and accounting treatment before treating it as a supplier-payment rail.
International vendor payment pre-release check
- The invoice, contract, purchase order, and receiving evidence agree on what is owed.
- The legal payee and tax documentation were reviewed under the payer’s actual jurisdiction and facts.
- Required sanctions and counterparty checks are complete under the company’s risk-based program.
- The bank account or wallet belongs to the vendor and any recent change was independently verified.
- The currency, amount, charge allocation, exchange rate, fees, and expected net receipt were reviewed.
- The remittance reference will let the supplier apply the payment to the right invoice.
- The invoice has no paid, pending, or previously approved duplicate.
- The maker and approver evidence is retained with the payment record.
International vendor payments: specific questions
Should I send the invoice amount or enough for the vendor to receive the invoice amount?
Follow the contract and the vendor’s written instruction. They are not always the same outcome. SWIFT supports debtor, creditor, and shared charge arrangements, and banks in a correspondent chain may deduct charges. Ask the provider for the expected net receipt and record which party bears charges before sending.
What bank details do I need for an overseas supplier?
Usually the account holder’s legal name, bank name and address, account number or IBAN where used, SWIFT/BIC or a local bank code, currency, and payment reference. Exact fields depend on the corridor and provider. Validate format, then independently confirm ownership with a known vendor contact.
Can an international ACH payment replace a wire?
Sometimes, on a corridor your bank or provider supports. Nacha’s IAT format is the US ACH component of an international payment and includes information about transaction parties. It is not a promise that every destination, currency, urgency, or amount is eligible, so compare the actual quote and requirements.
Which IRS form should a foreign vendor give a US business?
There is no safe one-form answer. The IRS says foreign individuals commonly use W-8BEN and foreign entities W-8BEN-E to certify non-US status, while W-8ECI, W-8IMY, W-8EXP, and Form 8233 cover other cases. Get tax advice based on the payee and income.
How should I verify an emailed bank-account change?
Pause the change and call a known vendor contact using a number from your existing records or one you found independently. The FBI specifically warns businesses not to use contact information supplied by the potential scammer. Require a second internal approval before the changed beneficiary is paid.
Is stablecoin automatically cheaper than a bank payment?
No. Compare conversion, platform, network, custody, and off-ramp costs, plus the operational cost of supporting the wallet and chain. Also evaluate issuer, redemption, cyber, compliance, and network risks. Stablecoin is a rail choice, not a blanket exemption from payment controls.
What proof should I keep after an international vendor payment?
Keep the invoice and approval, verified beneficiary instructions, tax and compliance review references, provider quote, charge treatment, payment confirmation or transaction hash, bank or wallet debit, remittance reference, and exception correspondence. The record should connect one obligation to one authorized settlement.
