The feature of managing the rate of the room on the basis of the number of people staying in the room is not there in QloApps as of now. And the same goes with extra options like halfboard.
These features are in our roadmap and we will add them in our future updates. But right now, we cannot quote a particular time when these features will be added.
So if you want to add this feature in QloApps right now then you can opt for the Paid Customization.
For the customization please raise a ticket at https://webkul.uvdesk.com/en/customer/create-ticket/
Now, regarding the Last day booking price,
We have Feature price rule in QloApps by which you can increase or decrease the price of the room on specific days or date ranges.
But if you want the rates of the room to vary on the basis of how early or how late a room is booked then that feature is also not there in QloApps right now.
(ex: If booking for the 10th day of the month is done on 9th day then the price will be higher than the prices for the booking if it was made on the 1st day of the month.)
And for this feature also you can go for the Paid Customization.
