How can I enable automatic invoice creation for web bookings?
Under settings/web-booking, you will find the required function "Create invoices." The following options are available:

This option creates the invoice only if the payment has been fully received on the booking platform.

-"Always create invoices"
With this option, every invoice is created regardless of the payment status.
