🏄‍♂️How do I sell several timeslots at once as i'm selling a package of x bookings?

This is a premium feature of the app and you'll need to be Premium on the app to be able to use full day booking.

You'll need to create a "bundle booking" if you want your customers to be able to pick several time slots at once (opposed to what can be done on "regular booking").

Click on "my services" then click on "new service" and pick "bundle booking".

From there you can configure the service.
