Hey @Tonka73740 - great question!

We have integrations with both Stripe and PayPal. You can connect your Stripe or PayPal account to Calendly to collect payments when your invitees schedule with you. If you don't use these services, you could add a custom link to your confirmation page that leads to your preferred payment provider. You could also customize your invitee notification emails to include that link!

Our payment integrations are attached to your booking page/s, so if you are embedding your booking page/s on your Wordpress website (read more about how to do this here), that payment collection integration will still need to be set up in Calendly. 

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. I hope this helps!
