UK sellers on Amazon, eBay, Etsy and similar platforms are usually paid in the marketplace’s local currency, which means the exchange rate is applied to your income before it reaches a sterling account. Sellers who let the platform or their bank convert every payout often lose margin on the rate; holding the foreign currency and converting it deliberately protects it.
How do overseas marketplaces pay UK sellers?
When you sell on a US, EU or other overseas marketplace, buyers pay in their own currency and the platform settles your balance in that currency. To land the money in a UK current account, it has to be converted to sterling at some point — either by the platform, by a payment provider, or by you.
The choice of who converts, and when, is where the cost sits. Many platforms offer to pay you directly in sterling using their own conversion, which is convenient but applies whatever exchange rate they set. The alternative is to receive the payout in the original currency into a multi-currency or receiving account, then convert it yourself. Our guide to getting paid in a foreign currency covers the individual side of the same problem.
Where do UK online sellers lose money on currency?
The main leak is the margin built into the exchange rate. When a platform or bank converts your payout, the rate you receive usually sits a little away from the mid-market rate, and that difference is the cost. It is easy to miss because it is not billed as a separate fee — it is simply baked into the number of pounds you receive.
Sellers who source stock abroad can pay this twice: once converting foreign sales into sterling, and again converting sterling back to pay overseas suppliers. Every round trip through the exchange rate is a chance to give margin away. The mechanics of these charges are set out in our guide to international transfer fees.
Worked example: what does a currency margin cost an online seller?
Take a UK seller receiving $120,000 a year in payouts from a US marketplace, converting at an illustrative GBP/USD rate of 1.28.
- At the mid-market rate, $120,000 is worth about £93,750.
- If the rate you actually receive carries a margin of an illustrative 2%, the conversion costs roughly £1,875 over the year.
- Trim that margin to an illustrative 0.5% and the cost falls to about £469 — a difference of roughly £1,400 on the same sales.
The figures are illustrative, but the principle holds: on recurring foreign-currency income, small differences in the rate compound into a meaningful annual sum. A 2% margin on £90,000 of turnover is £1,800 — money that comes straight off your margin. You can check live pricing on our currency converter.
Platform conversion vs bank vs multi-currency account and specialist: which suits a seller?
| Method | How it works | Trade-off |
|---|---|---|
| Platform auto-conversion | The marketplace pays you in sterling using its own exchange rate | Simple, but you accept whatever rate the platform sets on every payout |
| High-street bank conversion | Receive in foreign currency to a bank account and let the bank convert | Familiar, but the rate and any receiving fees are set by the bank |
| Multi-currency account plus specialist | Hold the payout in its original currency, then convert deliberately | More setup, but you control the timing and the route of each conversion |
Many established sellers use the third approach, pairing a multi-currency receiving account to collect payouts with a business currency account to convert on their own terms.
How can you protect your margin when you sell in foreign currencies?
Three tools do most of the work for a seller with steady overseas income.
- Hold the currency. Receiving payouts in their original currency means you are not forced to convert on payout day, and can convert when it suits your cash flow.
- Fix a rate for known costs. If you have predictable foreign-currency outgoings, such as supplier invoices, a forward contract can fix the rate for up to 12 months ahead so your margins are not at the mercy of the market.
- Set a target rate. A market order can convert automatically if the rate reaches a level you choose, without watching the screens.
These are the same tools UK exporters use to steady revenue, covered in our guides to FX hedging strategies and exporter FX strategy.
What are the tax and reporting rules for foreign-currency sales?
UK businesses must keep records and report income to HMRC in sterling, which means converting foreign-currency sales at an appropriate exchange rate. HMRC publishes monthly exchange rates that businesses can use for customs and VAT purposes, and its guidance on tax on foreign income sets out how overseas earnings are treated.
Reporting in sterling is a separate matter from the rate you actually convert at. Keeping clear records of the rate used for each conversion helps at year end, and the profit or loss between the rate on the sale date and the rate on the conversion date can matter for your accounts. For company earnings brought back to the UK, see our guide to repatriating overseas earnings. This is general information, not tax guidance for your situation, so a qualified accountant should confirm the treatment.
What currency mistakes do online sellers make most often?
- Accepting the platform’s conversion by default. The convenient option applies the platform’s rate to every payout, which adds up over a year of sales.
- Converting the full balance the moment it lands. Payout day is rarely the best moment to convert; holding the currency gives you room to plan.
- Double-converting to pay suppliers. Converting foreign income to sterling, then sterling back to pay an overseas supplier, pays the margin twice when holding the currency could avoid one leg.
- Ignoring the mid-market rate. Without a reference rate, it is hard to see the margin you are paying. The pound to euro outlook and the converter help you benchmark.
- Leaving supplier costs unhedged. If your buying prices are in a foreign currency, an unhedged rate move can quietly erode the margin you priced your products on.
How does a specialist currency broker help online sellers?
A specialist helps a seller collect payouts in their original currency, convert them on a schedule that suits cash flow, and fix rates for known supplier costs so margins are protected. For a business paying overseas suppliers as well as receiving foreign income, that can mean holding several currencies and moving between them without a round trip through sterling each time.
Cambridge Currencies is a UK specialist currency broker that supports online sellers and other businesses with cross-border income and payments. Funds are safeguarded by our FCA-authorised partners Currencycloud and ScioPay, and every transaction is completed by phone with a dedicated specialist who understands your trading pattern, rather than through an app. For sellers importing stock, our guide to paying overseas suppliers covers the payment side.
Frequently asked questions
Should I let Amazon or eBay convert my payouts to sterling?
You can, and it is the simplest option, but the platform sets the rate. Sellers with regular overseas income often prefer to receive payouts in the original currency and convert separately, so they control the timing and route of each conversion.
What is a multi-currency receiving account?
It is an account that lets you receive and hold funds in several currencies, such as US dollars or euros, without converting them immediately. It gives an online seller local account details to give to a marketplace, and the choice of when to convert to sterling.
Can I fix the exchange rate on money I will receive from sales?
Sales income is uncertain in amount, so it is harder to hedge than a known cost. It is more common to fix rates for predictable outgoings, such as supplier invoices, using a forward contract, while holding incoming currency and converting it deliberately.
Do I pay UK tax on foreign marketplace income?
UK-based businesses are generally taxed on their worldwide income and must report it to HMRC in sterling. The GOV.UK guidance on foreign income explains the principles, and an accountant can confirm how it applies to your business.
What rate should I use to record a foreign-currency sale?
HMRC publishes monthly exchange rates that businesses can use to convert foreign-currency transactions for customs and VAT. Keeping a consistent, documented approach to the rate you use makes your records easier to reconcile.
Is this worth doing for a smaller seller?
It scales with turnover. The more foreign-currency income you handle, the more the margin on conversions matters. Our minimum transfer is £5,000, so it tends to suit sellers with meaningful, regular overseas payouts.
