How Money Moves Across Borders When You Accept Payments Overseas

What Overseas Payment Processing Actually Is

Overseas payment processing means accepting money from customers in other countries and converting it into your home currency so you can use it. The money doesn't move directly from their bank to yours — it travels through a chain of banks, currency converters, and payment networks, each taking a small cut and adding a small delay. Your job is to pick which company handles that chain for you.

If you sell online, ship internationally, or work with clients abroad, you're already dealing with overseas payments whether you know it or not. The question is whether you're paying too much for the privilege and whether you understand what's actually happening to the money between when your customer clicks "pay" and when it lands in your account.

Key Takeaways

• Overseas payments involve currency conversion, and the exchange rate you get depends on which processor you use — the difference between processors can cost you 2 to 4 percent of every transaction.
• Money from overseas customers takes 3 to 10 business days to reach your account, not because of distance but because of how banking networks clear international transfers.
• You pay fees at multiple points: the processor takes a percentage, the receiving bank may charge a flat fee, and currency conversion itself has a markup built in.
• Processors that advertise "no foreign transaction fees" usually hide the cost in their exchange rate, so comparing the final amount you receive is more useful than comparing advertised fees.
• Some payment processors handle overseas transactions automatically; others require you to set up a separate account or choose a different product tier.

How Currency Conversion Actually Works

When a customer in the UK pays you in pounds, you don't receive pounds — you receive dollars (or whatever your home currency is). Someone has to convert those pounds, and that someone is your payment processor. They buy pounds at one rate and sell them to you at a higher rate. The difference is their profit, and it's where most of your cost actually lives.

The real exchange rate — what banks pay each other — changes every second. Your processor doesn't use that rate. They use a rate they set, which is always worse for you. A processor might advertise "no conversion fee," but their exchange rate might be 2 to 3 percent worse than the mid-market rate. Over a year of international sales, that adds up to real money.

To see what you're actually paying, don't compare fee percentages. Instead, ask each processor: "If a customer in Canada pays me 100 Canadian dollars, how many US dollars do I receive?" Write down the answer from three different processors. The difference between the highest and lowest is what you're losing to conversion markup.

The Fee Structure: Where Your Money Goes

A single overseas transaction involves fees at three separate points, and most processors don't make this clear.

The processor's percentage: Stripe, PayPal, Square, and others charge a percentage of the transaction (usually 2.2 to 3.5 percent) plus a flat fee per transaction. This applies whether the customer is overseas or not.

Currency conversion markup: This is separate from the processor's percentage. The processor converts the foreign currency and marks up the exchange rate. This can be 1 to 3 percent of the transaction value, and it's often invisible because it's baked into the rate they quote you.

Receiving bank fees: Your own bank may charge a fee to receive international wire transfers. This is usually $15 to $50 per transfer, though some banks charge per transaction and others charge a monthly flat rate for international receiving. Call your bank and ask: "Do you charge to receive international ACH transfers or wire transfers, and if so, how much?"

A $1,000 transaction from overseas might look like this: processor takes $30, currency conversion costs you $20, your bank takes $15. You receive $935. That's 6.5 percent gone before the money touches your account.

How Long Overseas Payments Actually Take

Money from overseas doesn't move slowly because it has to travel far. It moves slowly because of how international banking networks work. A payment from Japan to the US doesn't go directly — it goes through correspondent banks, clearing houses, and regulatory checkpoints. Each one adds a day or two.

Most overseas payments take 3 to 10 business days to settle. The timeline depends on which country the money is coming from, which banks are involved, and whether the payment goes through ACH (slower, cheaper) or wire transfer (faster, more expensive). Your processor will tell you a standard timeline — usually 5 to 7 business days — but actual times vary.

If you're waiting for money to pay a supplier or make payroll, this delay matters. Some processors offer faster settlement for an extra fee, usually 1 to 2 percent. Others let you borrow against pending international transfers. Ask your processor what options exist before you need them.

Which Processors Handle Overseas Payments and How

Not all payment processors treat overseas transactions the same way. Some have built-in support; others require you to upgrade your account or use a different product.

Stripe accepts payments from customers in 195 countries and deposits money in your home currency. They charge their standard processing fee plus a currency conversion markup. No separate setup required.

PayPal lets customers pay you in their local currency or in yours. If they pay in their currency, PayPal converts it. If you have a PayPal Business or Premier account, you can also receive direct bank transfers from overseas customers, though this involves additional fees and setup.

Square processes overseas payments through their standard merchant account, but the conversion markup and fees are higher than Stripe's. International payments are available but not their primary focus.

Wise (formerly TransferWise) specializes in international transfers and currency conversion. They're not a payment processor in the traditional sense — customers can't pay you directly through Wise — but if you receive regular international payments, you can use Wise to convert and move money at a lower cost than your bank or processor would charge.

Your bank can receive international wire transfers and ACH transfers directly, but banks typically charge higher fees and worse exchange rates than payment processors. This is usually your most expensive option.

Reducing What You Pay on Overseas Transactions

The easiest way to cut costs is to negotiate your processor's rate if you're processing high volume. Stripe and Square both offer volume discounts — if you're processing $50,000 or more per month, contact their sales team and ask what they can do on conversion markup.

If you receive regular payments from the same country, open a local bank account there. A UK customer paying a UK bank account costs them nothing and costs you only your bank's receiving fee, not a currency conversion. Services like Wise, Revolut, or Payoneer let you open accounts in multiple countries without living there.

For very large or very frequent international payments, ask your processor whether they offer batch settlement. Instead of converting each transaction individually, you can accumulate payments and convert them once a week or once a month. This reduces the number of times you're hit with conversion markup.

Finally, be transparent with overseas customers about who pays conversion costs. Some businesses add a small surcharge for international payments, or they quote prices in the customer's local currency and let the customer's bank handle conversion. This shifts the cost to them, which is fair if they're the ones choosing to pay in their home currency.

What Happens When Payments Fail or Get Rejected

Overseas payments fail more often than domestic ones. A customer's bank might reject the payment because it looks suspicious, the amount exceeds their daily limit, or the payment method isn't set up for international transfers. Your processor will usually retry the payment once or twice automatically, but after that it's on you to follow up.

If a payment fails, you don't pay the processor's fee — most processors don't charge for failed transactions. However, if your processor attempted currency conversion before the payment failed, you might see a temporary hold on the customer's account that takes a few days to clear. This isn't your problem, but it's worth knowing so you can explain it to the customer.

Chargebacks on overseas payments work the same way as domestic chargebacks, but they take longer to resolve — usually 60 to 90 days instead of 30 to 45. Keep detailed records of what you shipped, when it shipped, and any tracking information. International shipments are harder to prove, so documentation matters more.

Frequently Asked Questions

Do I need a special merchant account to accept overseas payments?

No. Most payment processors handle overseas payments through your existing account. However, some banks require you to notify them before accepting international payments, and a few older merchant accounts don't support it at all. Call your processor and ask whether your current setup handles overseas transactions or whether you need to upgrade.

What's the difference between a wire transfer and ACH for international payments?

Wire transfers are faster (1 to 3 days) and more expensive ($25 to $50 per transfer). ACH transfers are slower (5 to 10 days) and cheaper ($5 to $15 per transfer). Your processor chooses which method to use based on the country and the amount. You usually can't pick.

Can I ask my customer to pay in my home currency instead of theirs?

Yes. If you quote prices in your currency, the customer's bank handles conversion and they pay the cost. This protects you from conversion markup, but it may make your prices look more expensive to overseas customers. Many businesses quote in both currencies so customers can choose.

What if my processor's exchange rate is worse than the real rate?

That's normal and legal. Processors mark up exchange rates as part of their profit. If the markup is too high, switch processors. Before you do, confirm you're comparing the same thing — ask each processor for the exact amount you'd receive on a specific transaction, not just their advertised rate.

Do I have to wait for the full settlement period before I can use the money?

Usually yes, but some processors offer early settlement for a fee. Stripe offers Instant Payouts (for a percentage of each transaction), and some banks offer overdraft against pending international transfers. These options cost money, so only use them if the delay actually costs you more.
