The day and the night audit
What closing a day does, and what stops it closing
Closing the day: by itself, or by a personEach hotel chooses whether its day closes by itself at an hour, or when a person runs the night audit — and who may do it. Until it is closed, check-in waits.
What the night audit actually doesIt closes the day: posts room and tax, marks no-shows, freezes the figures and moves the date on.
Tonight is charged at check-out timeOnce the hotel's check-out time passes, every guest staying on is charged for tonight. The audit does not charge it again.
Running it, and what stops itThe Night audit tab lists what is in the way. Clear those, then run.
When the night audit will not runIt lists what is in the way. Each item is something that would make the day's figures wrong.
After the audit has runThe day is closed. Corrections belong to today, as adjustments, not as edits to yesterday.
