Collect payments with Paypal
It's currently possible to collect payments from your clients with Stripe and we're planning to support Paypal in the near future.
If you want to be notified about it, please let us know: firstname.lastname@example.org.
In the meantime, you can set your Paypal payment link as "redirect URL" so that your invitees will be redirected to your Paypal page to pay upon booking:
I would recommend you to turn on Tentative bookings so that it will require your confirmation (so that you can verify that the payment was made) before adding the event to your calendar.
