Guestline has recently improved the report pull functionality and clients might need to use the one named New Actual&Forecast
The RoomPriceGenie Reporting feature exclusively works with Confirmed bookings. Other bookings statuses such as Provisional, Waitlisted, and Non-Guaranteed won't be considered for the Revenue calculation, and this could lead to discrepancies with the Guestline report.
It is important for clients to know to please pull the New Actual & Forecast report, applying the Reserved/Confirmed bookings and excluding other statuses, to have a better view and comparison data.
