How to control staff fraud at a hotel?

For example, the hotel owner is away. The responsible staff may report to the owner that 10 rooms are occupied but in fact 15 rooms are occupied. After the guests check out, the staff can pocket revenues from the 5 rooms. How can we prevent this? Is there a business solution for this? References for more information appreciated.

You need a reliable head housekeeper. Either those rooms the employees sold didn't get clean because they didn't end up on the dirty rooms report - or they did get cleaned and housekeeping is either complicit in the scam or ignorant of the fact that they weren't recorded as being sold. Not sure what type of hotel management software you are using but there are solutions to this.

Tell the owner ?

Surely this would be better asked on a message board for the hotel industry? Try this website. http://www.ahla.com/

This happened to my friend when she owned a hotel. But only 1 person was doing the cheating; and she was discovered when she loaded a U-Haul with stolen stuff and left town. She later apologized and asked to come back and work again. My friend sold the business.

There is no way except to manage the hotel yourself so you oversee everything..
