It is possible to choose the zloty and euro as currency for payments with Przelewy24 via Mollie.
If you choose the zloty, make sure you offer the products on your webshop in zlotys.
If you offer the products on your webshop in euros, you can choose to have the amount automatically converted to Polish zloty. The exchange rate at the time of payment is used for this; no exchange rate differences or other costs are charged to your business.
Payouts will always be done in euros.
