When a reservation is made an invoice is created. The invoice status by default is unconfirmed. Note that there is no "Confirm" button within each new invoice. The only way to confirm a reservation is to process or record a payment for the reservation deposit.
Your reservation deposit can be configured here:
Confirming a Reservation from the Invoice Screen
Reservation Status: Will initially be set to Unconfirmed
Confirmation Breakdown: Displays the amount required to confirm the reservation.
