When Paying Abroad, Which Currency Should You Use

Quick Answer

The Short Answer, and Why It Matters

The currency you choose decides who pays for the conversion. That is the whole question.

When you pay in the supplier's currency, you buy that currency and send it. The exchange rate is quoted to you before you approve the payment, so the cost is visible and comparable across providers. When you pay in your own currency, the supplier's bank converts it on arrival, usually at a retail rate with a margin built in, and may also deduct a receiving fee.

Both routes involve a conversion. The difference is who controls it and whether you can see the price in advance.

For a single small payment, the difference might be a few dollars. For a business paying suppliers every month, it is a line item worth managing.

Why Paying in Your Own Currency Often Backfires

Paying in dollars, pounds or euros feels safer because the amount is fixed on your side. That certainty has a price, and it is usually paid by the supplier, who then prices it back into future quotes.

There are three mechanisms at work.

First, the receiving bank converts at its own rate. Retail conversion margins at banks commonly sit well above the interbank rate, and the gap is rarely disclosed as a fee. It simply appears as a smaller credit.

Second, the beneficiary may be charged a conversion or handling fee. In some markets, receiving a foreign currency payment triggers a fixed charge that the supplier did not budget for.

Third, the supplier has to manage the exposure. If they are paid in a currency they do not hold, they carry the risk between invoice and conversion, and prudent suppliers add a buffer to their pricing.

The result is that "paying in your currency for certainty" often costs more over a year than paying in the supplier's currency and comparing rates properly.

How the Conversion Actually Happens

Every international payment passes through a chain. You fund the payment in a currency. Your provider or bank converts it if needed. Correspondent banks may convert or deduct along the route. The beneficiary bank credits the account, sometimes after another conversion.

Each conversion point can apply a margin. The cleanest payments have one conversion, on your side, at a rate you were quoted. The messiest have two or three, and the only visible number is the final credit.

This is why the useful comparison is never the transfer fee. It is the amount that lands, in the currency the supplier expects, on the date they expect it.

The European Central Bank publishes daily reference rates, which give you a neutral benchmark. The Bank of England publishes comparable data for sterling. If a provider's rate is far from the reference rate, the difference is the margin you are paying.

When Local Currency Is the Right Choice

Paying in the supplier's currency is the default, but there are exceptions worth knowing.

The contract fixes the price in your currency. If the invoice is denominated in dollars, pay dollars. Converting unilaterally creates a mismatch and can trigger a dispute.

The supplier is in a country with currency controls. Some markets restrict local currency conversion or require documentation. In those cases the supplier may prefer settlement in a major currency.

The amount is small and the fee dominates. On a two hundred dollar payment, a fixed conversion charge can be a large share of the total. Sometimes the simpler route is cheaper in absolute terms even if the rate is worse.

You have a natural offset. If you already hold the supplier's currency from sales in that market, paying from that balance avoids a conversion entirely.

The supplier quotes both and prices the difference. Some suppliers offer a local currency price and a foreign currency price. Compare the two against the reference rate and choose the cheaper one, not the more familiar one.

Three Common Scenarios

Scenario	Best currency	Why
Monthly supplier payments in China, invoiced in dollars	US dollars	The contract and the supplier's banking setup are dollar based
Tuition payment to a European university	Euro	The university bills in euro and the conversion is visible on your side
Rent to a landlord in the UK	Pounds sterling	Local bills, local account, no receiving conversion
Equipment purchase from Japan invoiced in yen	Japanese yen	Avoids a double conversion through dollars
Small one-off payment to a freelancer	Supplier's currency if supported	One clean conversion instead of two

The pattern is straightforward. Follow the invoice currency where one exists, and where it does not, ask the supplier which currency avoids a conversion on their side.

Comparing Routes by Net Cost

Build a simple comparison for a real payment amount.

Start with the mid market rate for the pair on the day. Calculate what the supplier should receive at that rate. Then ask each provider what the supplier will actually receive, in the destination currency, after all fees.

The difference between the two numbers is the total cost, expressed as a percentage. This single figure captures the transfer fee, the rate margin and any intermediary deduction.

Do this for two or three providers on the same day, for the same amount. The ranking often changes with the amount, because flat fees dominate small payments and rate margins dominate large ones.

For a payment of fifty thousand dollars, a one percent rate difference is five hundred dollars. That is usually more than every visible fee in the transaction combined.

Forward Contracts and Rate Planning

If you know a payment is coming in three months, you can fix the rate today through a forward contract with a bank or a specialist provider. You agree an amount, a date and a rate, and settle when the payment falls due.

Forwards are useful when the margin on a deal is thin and a currency move would erase it. They are less useful for small recurring payments, where the administrative cost outweighs the benefit.

A simpler alternative is to hold a balance in the currency you pay in, funding it when the rate is favourable. That requires discipline and a treasury process, but it removes the monthly exposure without a contract.

Either way, the decision should be made before the invoice arrives, not on the day it is due.

Where DapsyPay Fits

The currency question is really a transparency question, and transparency is where DapsyPay is built to help. The platform sends payments on conventional rails such as SEPA and ACH, shows the rate and fee before you approve, and pays directly into the supplier's bank account.

That means you can pay in the supplier's currency without guessing what the conversion costs. There is no limit on transfer size, which matters when a single equipment payment is larger than a retail transfer product allows, and bulk sending is supported for businesses paying several suppliers in the same cycle. Because the money moves on standard banking rails, the supplier sees a normal bank credit rather than a third party transfer that needs explaining to their finance team.

The practical workflow is to agree the invoice currency, check the quoted rate against the reference rate, and approve the payment with the net amount visible. If the number works for the deal, send it. If it does not, you know before the money leaves.

Common Mistakes

Assuming your currency is the safe choice. It shifts cost to the supplier and often returns in higher prices.

Comparing transfer fees only. The rate margin is usually the larger number on business sized payments.

Letting the beneficiary bank convert. You lose visibility and the rate is rarely competitive.

Ignoring the invoice currency. Paying in a different currency than the invoice creates reconciliation problems and disputes.

Skipping the reference rate check. Without a benchmark, you cannot tell a good rate from a bad one.

Hedging without understanding the contract. A forward you cannot fulfil becomes a separate loss.

Conclusion

Choose the currency that avoids an unnecessary conversion, and make the one conversion you cannot avoid visible. That usually means paying in the supplier's currency, checking the rate against a reference, and comparing providers on the net amount that arrives.

DapsyPay makes that comparison simple, with fast transfers on conventional rails, no limits, transparent pricing and direct bank delivery. Decide the currency before the invoice lands, and the payment stops being a source of surprises.
