Yes. If you already have your own website you do not need to use the Kavuo one: you paste one line of code into it and your customers book without leaving your site, with the same form, tables, waitlist and notifications as every other Kavuo customer. It is available on every plan with no commission per booking.
When you create your account you choose Ya tengo web (I already have a website) and the Kavuo website stays off: your Kavuo address becomes just a bookings page that Google does not index. You can change it whenever you want from the dashboard.
In the dashboard (Configuración > Integraciones) you get the code ready to copy and a button to try the form.
