Not yet. Adfin only accepts payments in GBP at the moment. Multi-currency support is on the roadmap for later this year.
Customers based outside the UK can still pay your Adfin invoices by card. Their bank will convert the payment from their local currency to GBP at checkout. They may pay a currency conversion fee, and some banks add a cross-border transaction fee on top.
Direct debit and Pay by Bank are UK-only and not available to overseas customers.
