Selling across six currencies usually means six versions of the truth. A DTC brand running Shopify EU, Amazon.de, Amazon.co.uk, and Zalando ends up with revenue sitting in EUR, GBP, and USD, and none of it reconciles on its own. Someone has to convert it. Usually that someone is a finance person exporting CSVs at 11pm before a board meeting, applying whatever spot rate Google gives them that day.
