Paid in dollars? Spending in euros? Sorted.

Selling abroad shouldn't make your accounts complicated. This converter uses the official HMRC exchange rates — the very same rates we apply when we prepare accounts and tax returns for clients trading in multiple currencies. Multi-currency is business as usual here.

Not sure which rate your situation calls for — monthly, year-end, or the day's spot rate? Speak to us — picking the right one is part of the job.
