To be able to start selling a paid ticket, you first need to create an invoicing profile.
You can do this by going to the “invoicing” section within the “my profile” area, or directly when you create the paid ticket.
To create the invoicing profile, you need to fill in your fiscal information, and connect a PayPal or Stripe account. You will then be able to attach the invoicing profile you created to a ticket you have for sale.
You can also create various invoicing profiles, and choose every time which invoicing profile to attach to each specific event.
