Q: How do I do a bulk check-out?
A: This function was added in version 6, but it's easy to miss. It's called "Auto-Checkout today's departures", and it's only available on the Departures tab right-click menu.
From the documentation:
Auto-Checkout today's departures
This function can be found on the right-click menu of the Departures tab view. Selecting this option will check out all reservations currently checked in with a last night equal to yesterday's date (i.e. departing today), provided that their Paid-thru Date is set to their Last Night and they have a $0 reservation balance. If the reservation has any Guest reservations, they must also have a $0 balance and be due out today or earlier, and the Guests will be automatically checked out also.
