Short answer: A workplace theft investigation is a step-by-step fact-finding process: define what is missing, review records, check the people involved, conduct interviews, and document what is found. The goal is reliable facts, gathered with discretion, so the owner can decide what to do next.
How common is employee theft?
More common than most owners expect. The Association of Certified Fraud Examiners’ 2024 Report to the Nations estimates that a typical organization loses about 5% of its revenue to fraud each year. The same report found the median scheme ran 12 months before it was caught (ACFE, 2024 Report to the Nations).
A year is a long time to be losing money without knowing why.
What are the warning signs of employee theft?
No single sign proves anything. Patterns are what matter:
-
Cash, inventory or supplies that do not match the records
-
Voids, refunds or discounts that cluster around one person or one shift
-
Reluctance to take time off or let anyone else cover a task
-
Unexplained vendor changes or invoices that never get questioned
-
Expenses, mileage or hours that do not line up with the work done
-
A lifestyle that suddenly outpaces the paycheck
Any of these can have an innocent explanation. That is exactly why an owner should avoid confronting someone before the facts are in.
Why should you not confront the employee first?
Confronting someone early can make the facts harder to gather. Records can be changed, items can go missing, and a person who had nothing to do with it may feel accused. A discreet review of the facts first can help protect the business and the people who did nothing wrong.
What does a private investigator do in a workplace investigation?
Every case is different, but our workplace investigations commonly include steps like these:
- Scope the problem. It starts with what is missing, since when, who has access, and what the owner already knows. A clear scope keeps the work focused.
- Review the records. Sales data, inventory counts, schedules, access logs and expense reports show where the numbers break.
- Check the people involved. We run background and criminal records checks on everyone involved. A background investigation can surface prior issues or undisclosed connections to vendors.
- Conduct interviews. Investigators interview the people who may know something, including staff, managers and vendors, and record what each person says.
- Observe the pattern. Depending on the case, an investigator may observe and document activity in public areas, or on the business’s own premises with the owner’s cooperation.
- Document everything. Dates, times, photos, video and notes are typically organized into a written report.
- Review the findings with the owner. The investigator explains what was found and what was not. The decision stays with the business.

How long does a workplace investigation take?
It depends on the scope. A narrow question about one register or one vendor can move quickly. A pattern that spans months of records takes longer. Ask any investigator what is realistic for your situation before you hire.
How do you choose an investigator for this kind of work?
Check the license, ask who will actually do the work, and ask how findings are documented. We cover those questions in How to Check a Private Investigator’s License Before You Hire. Florida’s license lookup is at FDACS.
Frequently asked questions
Should I tell my staff I hired an investigator?
That is the owner’s call. Many owners keep it limited to the people who need to know, so the review stays discreet.
Can an investigator tell me who is responsible?
An investigator reports what the records and observations show. Any conclusion about a person should rest on documented facts, not a hunch.
What should I do before calling?
Write down what is missing, the dates you noticed, and who has access. Do not change records, and keep the originals.
What if nothing turns up?
That is a result too. It can clear a person who was under suspicion and point the review somewhere else.
