Startup Idea: Pattern Detection Software for Auditing Employee Revenue

Startup idea to develop a software that can detect and flag abnormal patterns in reported revenue by employees in a gaming business. The system would help auditors differentiate between normal and abnormal behaviors to catch potential theft and irregularities.

I am an auditor and have been for the last nine years. I audit gaming revenue and employee revenue. For the employees I audit roughly between 25-30 employees. I would really like a program that detects patterns in reported revenue by employees. What I mean is that it i very difficult task to keep track of all employees reported revenue and losses. I have a difficult time determining patterns that are normal to operating the business and those which are abnormal and could be flagged as theft. I have caught a few people over the years stealing that exhibited patterns. I would like a software program that can differentiate between normal behaviors and abnormal ones. I would also like it to flag abnormal behaviors and notify me when they occur again so that I can use that information to watch them more closely.
