Invoicing in a foreign currency: a practical guide

International clients are a gift, until the exchange rate moves and half your margin disappears. Decide on the currency, the rate and who carries the risk before you send the invoice.

Which currency to use

Your local currency protects you from rate movements, but the client carries the conversion cost and uncertainty.
The client’s currency is convenient for them, and often wins deals. You take the exchange risk.
A common currency such as USD or EUR often suits cross-border work between third countries.

Pick one currency per contract and put it in the quote.

What to show on the invoice

The currency name or code (USD, EUR, GBP) next to every amount. All InvoiceDesk generators support many currencies and symbols.
If you convert for tax, the rate used and its source and date. For example, “1 EUR = 0.86 GBP, rate published by the ECB on 15 Oct 2026”.
In the UK, the VAT amount of a VAT invoice in a foreign currency must also be shown in pounds sterling. Other countries have similar rules.
Your bank details for that currency, including IBAN and SWIFT/BIC where relevant.

Reduce exchange-rate risk

Shorten payment terms. Rates move less over 14 days than over 60.
Invoice at a fixed rate agreed in the contract.
Add a clause for large moves, such as a review if the rate changes more than 5%.
Hold the foreign currency in a multi-currency account if you will spend it in that currency.

Bank fees and who pays

International transfers often lose money to fees and poor rates. Say who pays the bank charges: “All bank charges are for the payer’s account” is common. Receiving the full amount may require the sender to choose the “OUR” fee option. Compare providers’ total costs, not just the headline fee.

Tax and records

You usually have to convert foreign income to your home currency for tax, using an official or consistent rate. Keep a note of the method. VAT, GST and reverse-charge rules on cross-border invoices are covered in reverse charge explained.

Frequently asked questions

Can I change the currency after sending?

Better to issue a credit note and a new invoice than to change a sent one.

Which exchange rate should I use?

An official source such as a central bank or your tax authority’s published rate, applied consistently.

Do I charge VAT or GST to foreign customers?

It depends. Business customers abroad are often outside the scope or reverse charged. See the guide linked above.

What are IBAN and SWIFT/BIC?

Codes that identify your account and bank for international transfers.

Do I need a separate invoice template per currency?

No. The generator lets you set the currency symbol and code on each invoice.
