Invoice Currency Converter

Convert an invoice amount between 26 currencies using the European Central Bank's euro reference rates from 27 October 2026, or an exchange rate you enter yourself. The built-in rates are a dated snapshot, not live prices, so use them to estimate and check. For the figure on a real invoice, use the rate your contract or tax authority calls for; the rules for the UK, EU and US are below.

Best for: Freelancers and small businesses billing abroad who need to quote, check or explain a converted invoice amount.

Built-in rates are ECB euro reference rates published on 27 October 2026. They are indicative and are not updated automatically. Enter the rate you will actually use before putting a converted amount on an invoice. Changing either currency clears your rate.

Converted Amount

EUR 896.86

1 USD = 0.8969 EUR (1 EUR = 1.1150 USD)

ECB reference rates of 27 October 2026, crossed through the euro.

Indicative only. The amount you receive depends on your bank or payment provider's rate and fees on the day of payment.

Where the built-in exchange rates come from

Every built-in rate is taken from the European Central Bank's euro foreign exchange reference rates published on 27 October 2026, for example 1 EUR = 1.1150 USD and 1 EUR = 0.83658 GBP. The ECB states that the reference rates are published for information purposes only. Pairs that do not involve the euro, such as USD to GBP, are crossed through it: 0.83658 / 1.1150 = 0.7503 GBP per US dollar. This is the same method the EU VAT Directive describes for converting between two non-euro currencies.

The ECB does not publish rates for AED, SAR, NGN, KES, PKR, so the converter shows "Unavailable" for those currencies until you enter a rate. The snapshot is changed by hand, so the date above is the only date these rates are good for.

Which exchange rate to use on an invoice: UK, EU and US rules

You can usually invoice in any currency. The rules bite when tax has to be reported in your home currency.

WhereRuleOfficial source
United Kingdom (VAT)A VAT invoice may be in a foreign currency, but the total VAT must also be shown in sterling. Convert at the UK market selling rate at the time of supply or HMRC's published period rate; other rates need HMRC's agreement.HMRC VAT Notice 700, 7.6 and 16.4
European Union (VAT)Invoice amounts may be in any currency, but the VAT payable must be in the member state's national currency. Use the latest selling rate on that country's main exchange market when VAT becomes chargeable; member states must also accept the latest ECB rate.VAT Directive 2006/112/EC, Articles 91(2) and 230
United States (income tax)The IRS has no official exchange rate. It generally accepts any posted rate used consistently, applied at the spot rate when you receive, pay or accrue the item.IRS: Yearly average currency exchange rates

Worked examples: converting and the cost of waiting

Quoting a client in euros. A US freelancer bills USD 2,400. At the ECB rates of 27 October 2026, 1 USD = 1 / 1.1150 = 0.896861 EUR, so 2,400 x 0.896861 = 2,152.4664, which rounds to EUR 2,152.47. If the invoice is issued in euros, write that amount and note "converted at 0.8969 EUR per USD, ECB reference rate, 27 October 2026" so both sides can check it.

Exchange risk on a sterling invoice. The same freelancer bills a UK client GBP 5,000. At the cross rate of 1.3328 USD per GBP that is worth USD 6,664.04 on invoice day. If sterling falls 3% before the client pays on Net 30, the freelancer receives about USD 6,464.12, roughly USD 200 less, before any bank fees. Billing in dollars would have moved that risk to the client; billing in sterling with Net 14 terms would have cut the time exposed by more than half.

Rounding and showing the rate

  • Round once, at the end, to the currency's smallest unit. The converter rounds EUR, GBP and USD to cents and JPY and KRW to whole units.
  • Write the currency code next to every amount. "$1,000" could be US, Canadian, Australian or Singapore dollars; "USD 1,000" cannot.
  • State the rate, its source and its date if the invoice shows a converted figure, to at least four significant figures.
  • Record the rate you used in your own books. You will need it when you reconcile the payment that actually arrives.

Invoicing in a foreign currency with InvoiceQuickly

InvoiceQuickly lets you issue each invoice in one of seven currencies: USD, EUR, GBP, CAD, AUD, INR or PKR. It does not convert between them or look up exchange rates, and the dashboard keeps totals for each currency separate rather than adding them together. To bill a client abroad, pick their currency on the invoice, enter the amounts in that currency, and if they need a home-currency equivalent, add it with the rate and date in the invoice notes. See features and pricing.

When this isn't the right fit

You need a live or intraday rate. These rates are a single dated snapshot from 27 October 2026 and will drift further from the market every day after it.

You need to know exactly what will land in your account. That depends on your bank or payment provider's rate and fees on the day the money is converted; ask them for a quote.

You need rates for past dates, for example to restate last year's invoices. Use the historical series your tax authority accepts, such as HMRC's period rates or the ECB's published history.

Frequently asked questions

Are the exchange rates in this converter live?

No. The built-in rates are the European Central Bank's euro reference rates published on 27 October 2026. They do not update automatically, so treat them as indicative. For a real invoice, enter the rate your contract, bank or tax authority specifies in the "your exchange rate" box.

Which exchange rate should I use on an invoice?

Use the rate your contract names, and for tax amounts the rate your tax authority accepts. In the UK, VAT on a foreign-currency invoice must also be shown in sterling, using the UK market selling rate at the time of supply or HMRC's period rate. EU countries must accept the latest ECB rate for the VAT conversion. The IRS has no official rate and accepts any posted rate you use consistently.

Should I invoice in my currency or my client's?

Invoicing in your own currency moves the exchange risk to the client; invoicing in theirs makes paying easier for them but leaves you exposed until the money arrives. If you bill in the client's currency, agree in the contract which rate and which date apply, and keep payment terms short.

Why is my bank's rate different from this converter?

Reference rates are a mid-point snapshot taken once a day. Banks and payment providers quote their own buy and sell rates, may add a margin or fee, and move during the day. The amount that lands in your account is set by the provider's rate when the payment is converted.

How should I round a converted invoice amount?

Convert the total once, then round to the currency's smallest unit: cents for USD, EUR and GBP, whole yen for JPY. Converting each line and rounding separately can leave the lines a cent or two away from the converted total. Show the rate you used, to at least four significant figures, so the client can check it.

Can InvoiceQuickly convert an invoice to another currency?

No. InvoiceQuickly lets you issue each invoice in USD, EUR, GBP, CAD, AUD, INR or PKR, but it does not convert amounts or fetch exchange rates. Choose the invoice currency, enter amounts in that currency and, if your client needs a home-currency equivalent, add it with the rate and date in the invoice notes.
