Group Pro-Forma Tax Invoice
 Use the Group Booking  page to generate
         a group pro-forma tax invoice. This report is used to generate pro-forma tax invoices at
         properties that use guest invoicing. It is primarily used to collect advance deposits that
         are due prior to arrival of the guest. The pro-forma tax invoice is an estimate of the
         charges the guest will incur during their stay based on the rate and package information,
         and depicts what the guest's folio will look like at the end of their stay in the property.
         It also includes the estimated tax breakdown. The pro-forma folio includes the deposit
         amount and due date. Since this is not a final invoice, it does not need an invoice number.
            
   Note: You can print the Group Pro Forma invoice for Portugal only
            if the FISCAL property parameter is set to PT. This invoice
            includes the details such as QR code, ATCUD, electronic signature and sequential number.
            The invoice also displays the expected revenue and tax information.
