Shopify expanded multi-currency payouts to eligible Shopify Payments merchants in France. EUR remains the default payout currency; other currencies require additional bank accounts and an Advanced or Plus plan. Source officielle.
A practical check
List currencies actually collected, suppliers paid in those currencies, payout and conversion fees, and eligible bank accounts before enabling the feature.
A store charges in USD and pays a US supplier. It can compare a USD payout against conversion to EUR and a later payment back to USD. Fees and bank timing determine the actual result.
What the evidence supports
Receiving foreign currency does not automatically improve margin. Compare full fees and cash needs using real orders. Date the check and retain the source documentation so that later changes can be verified.
