To view POS orders by the service delivery date rather than the order confirmation date, the POS service must be set up as a multi-booking service. Orders for multi-booking services can be viewed by the date and time the service is booked in the "Reports" → "POS Reservation Report."
For products sold in shops other than multi-booking services, there is no specific service delivery date, so they can only be viewed by the reservation confirmation date in the "Reports" → "POS Sales Report." Alternatively, you can check orders linked to hotel reservations from the "POS Orders" section on each reservation's detail page.
