In the Events section of your dashboard, find your event and choose Edit event and tickets from the side menu. Under the Event settings heading you’ll see a drop-down menu titled Currency.
Select the currency you want ticket buyers to purchase tickets in.
If you have an event where you want ticket buyers to checkout in multiple currencies then we suggest duplicating the event, with each copied event providing a different currency for ticket buyers. E.g. Event names could be "Festival Tickets EUR" Festival Tickets USD", "Festival Tickets GBP". This way ticket buyers have the choice of buying in their preferred currency and you can display prices dependent on the individual cost of collecting money from those regions.
Please note:
If your event is live you will need to switch back into Draft before you can change the currency.
Stripe and PayPal's fees will vary depending on which currency ticket buyers pay in.
