Removing Wix Bookings from your site and deleting the Wix App is really straightforward. You only need to remove the page that holds the Wix Booking app – and boom! You’ve removed Wix Bookings from your site.
Sidenote: You should know that this won’t cancel your Wix Bookings plan, you’ll only remove the app from your website. In other words, unless you cancel the Wix Bookings plan (more information), you’ll be requested to carry on paying for it.
