Click on the Operations Drop Down and then choose “Close Out.”
If any issues or times are not taken care of, the system will not let you close the day out.
Once you have cleared those issues, you can reopen the close-out and click on the green “Close Out” button on the bottom right side of the window. 
Once the close-out has been completed, the main booking screen will look different.
There will be a green banner with the closeout date and time.
