Hi ​@Birgit Steinich - Thanks for reaching out here.

At this time, our payment integrations can accept payments using the following currencies:
$ AUD - Australian Dollar
$ CAD - Canadian Dollar
€ EUR - Euro
£ GBP - Pound Sterling
$ USD - United States Dollar

If you'd prefer to collect payment with a different currency, you could include a payment link on your confirmation page to direct invitees to your preferred payment portal. Customizing your invitee notification emails to include that link might do the trick as well! While these options won't ensure users pay for the service prior to booking, it may allow some more flexibility.

Additional currencies is a feature request with our team, so I’ve added this post as support. Hopefully we’ll see more added on to this feature soon. Let me know if you have any questions.
