By default, all card transactions are debited from your GBP business account. If you would like your euro card transactions to come from your business euro account you need to activate the “Currency Controls” under “Card and Currency Controls” screen. When this is activated, all card transactions in euros will be debited from your euro business account. All other currency transactions will come from your GBP business account.
If you would like all card spending (including euro) to come from your GBP business account, please return to the card control screen and turn off “Currency Controls”.
