The Complete Guide to International Business Payments for US Companies

International business payments are the methods a US company uses to send money to, or receive money from, a party in another country — most commonly international wire transfers (SWIFT), specialized payment platforms (Wise, Payoneer, OFX and similar), global ACH, or a merchant account that accepts foreign cards. The right choice comes down to four variables: how fast the money must arrive, the size of the transfer, the currency it settles in, and how much foreign-exchange (FX) markup and per-transfer fee you are willing to absorb. Wires are the fastest and most universally accepted but carry the highest flat fees; payment platforms usually win on FX cost for routine, smaller transfers; global ACH is cheapest for recurring, non-urgent payments. This guide walks through each method, the true cost of moving money across borders, how to time payments against your cash flow, and — critically — how to fund a large overseas order when your deposits are strong but your bank balance is not.

The main ways to send and receive money across borders

Every cross-border payment method is a trade-off between speed, cost, and reach. Here is how the practical options stack up for a US operating business.

• International wire transfer (SWIFT): The default for large or one-off supplier payments. Funds typically move in one to three business days, are accepted almost everywhere, and are hard to reverse. Expect a flat outbound fee from your US bank (commonly $30-$50, labeled "for example") plus intermediary-bank fees that can be deducted mid-route, so the beneficiary sometimes receives less than you sent unless you mark the transfer "OUR" (sender pays all charges).
• Payment platforms (Wise, Payoneer, OFX, Airwall.-style providers): Built for cross-border commerce. They usually give you a rate close to the mid-market rate with a transparent percentage fee, hold balances in multiple currencies, and let you collect foreign-customer payments into local receiving accounts. Best for frequent, small-to-mid transfers and for freelancers and marketplaces.
• Global / international ACH (also called IAT): Cheapest per transaction and good for recurring, predictable payments to countries with compatible clearing systems. Slower (often three to five business days) and not available everywhere.
• Card and merchant acceptance: If you are the one getting paid by overseas customers, a payment processor that supports foreign cards and local payment methods (SEPA, iDEAL, Alipay) widens your customer base but adds processing fees and cross-border/FX surcharges.
• Multi-currency business account: Holding balances in EUR, GBP, CAD, etc., lets you pay suppliers in their own currency and time your conversions instead of converting on every transaction.

What an international payment actually costs

The sticker fee is rarely the real cost. Cross-border payments carry three separate charges that you have to add together to compare providers honestly:

1. The transfer / transaction fee — a flat charge (wires) or a percentage (most platforms).
2. The FX spread — the difference between the true mid-market exchange rate and the rate your provider gives you. This is where banks quietly make the most money; a spread of 2-4% on a large transfer can dwarf the flat fee.
3. Intermediary / correspondent bank fees — deductions taken by banks that relay a SWIFT wire between your bank and the beneficiary's bank.

Always compare on total landed cost: what leaves your account versus what the supplier confirms they received. Ask suppliers to confirm receipt in full — a shortfall usually means an intermediary fee you can eliminate by choosing the "sender pays all" option or a platform that uses local rails instead of SWIFT.

Example cost comparison across payment methods

The table below illustrates how the same payment behaves under different methods. All figures are illustrative ("for example") to show the shape of the trade-offs, not a quote.

Notice that no single row wins on every column. A $2,000 recurring payment and a $180,000 one-time equipment purchase should not use the same rail.

Getting the timing right: payments and your cash flow

Cross-border payments introduce a timing gap that domestic payments do not. A supplier wire may leave your account today but the goods ship in 30 days and reach your customers in 60 — meanwhile the FX rate can move against you between order and settlement. Three practices protect your cash flow:

• Match the payment method to urgency. Don't pay a flat wire fee and a fat FX spread for a routine payment that a platform transfer or global ACH could handle for a fraction of the cost days later.
• Consider forward contracts for large future payments. Many platforms let you lock today's rate for a payment due in weeks or months, removing FX uncertainty from a big purchase order.
• Hold a currency buffer. If you pay the same supplier country repeatedly, keeping a balance in their currency lets you convert when the rate is favorable rather than on the provider's clock.

The hardest timing problem is the one where the order is bigger than your bank balance — a supplier wants a 50% deposit on a container of inventory before your busy season. That is a financing question, not a payments question, and we cover it next. For the broader picture of managing the gap between paying out and getting paid, see our guide to business cash-flow management.

Funding a large overseas order when deposits are strong but cash is short

Here is the scenario we see constantly on the underwriting side: a healthy business with steady daily deposits lands a big opportunity — a bulk inventory buy, a supplier deposit, a customs and freight bill — that has to be paid to an overseas party now, weeks before the revenue from selling that inventory lands. The business is profitable; it just doesn't have the lump sum sitting in the account this week.

Traditional bank financing is often the wrong tool for this: it is slow, credit-score-driven, and rarely funds in time to hit a supplier's deposit deadline. A revenue-based financing (RBF) or MCA marketplace is built for exactly this timing problem. Instead of underwriting your credit score first, these funders underwrite your bank deposits and revenue — the cash actually flowing through your business. That matters when you need to move fast on an international payment.

Typical parameters for this kind of financing:

• Approval driven by bank deposits and revenue over credit score
• FICO 500+ generally considered
• Funding amounts starting around $10,000
• Decisions and funding often within 24-48 hours

You receive funds in your US account, then send the international payment through whichever rail fits (usually a same-day wire to hit a deposit deadline). Repayment is structured as a fixed share of your future receipts, which lines up with the sales cycle the inventory feeds. Nothing about this is guaranteed — approval and terms depend on your deposit history and revenue — but for a strong-revenue business racing a supplier deadline, it is frequently the only tool that funds in time. A marketplace matters here because it shops multiple funders on your one application, so you compare offers instead of taking the first one.

Decision framework: when each approach works best (and when to avoid it)

Use this to choose fast.

Use a bank SWIFT wire when: the payment is large or one-off, the beneficiary requires it, or a supplier deadline is hours away. Avoid when the payment is small and recurring — the flat fee and FX spread make it the most expensive routine option.

Use a payment platform when: you make frequent cross-border payments, want near-mid-market FX, or need to collect from foreign customers into local accounts. Avoid when the destination country or currency isn't supported, or a counterparty insists on a traditional bank wire.

Use global ACH when: payments are recurring, predictable, and not time-sensitive, and the country supports it. Avoid when you need the money to land in one or two days.

Use revenue-based / MCA marketplace financing when: you have strong, consistent bank deposits, need $10,000 or more to cover a supplier deposit or inventory buy, and can't wait weeks for a bank. It works best for businesses whose revenue arrives shortly after the overseas purchase pays off. Avoid when the purchase has no clear, near-term revenue tied to it, when your deposits are thin or highly erratic, or when a longer-term, lower-cost bank facility can realistically fund before the deadline — RBF is priced for speed and flexibility, not for financing that has no revenue event behind it.

Practical checklist before you send your first international payment

• Confirm the beneficiary details exactly — bank name, SWIFT/BIC, IBAN or local account number, and the beneficiary's legal name. A single wrong digit can bounce or misroute a wire, and recovery is slow.
• Verify the request out-of-band. Business email compromise fraud targets international payments; confirm any new or changed bank details by phone with a known contact before sending.
• Choose your fee option deliberately (OUR/SHA/BEN on wires) so you and the supplier both know who absorbs intermediary fees.
• Compare total landed cost, not just the headline fee — add the FX spread.
• Keep records for compliance. Retain invoices and payment confirmations; large or frequent cross-border flows can draw questions from your bank's compliance team.
• Line up funding before, not after, you commit to a large overseas order, so a deposit deadline never forces a bad payment decision.
