Fraud usually runs about a year before anyone notices. Here are five signs your Phoenix-area business shouldn't wait, and what to do before you call anyone.
You’ve got a feeling about the stockroom count, or a line in the books nobody can explain, or an injury claim that doesn’t sit right. You haven’t said a word to anyone, because accusing the wrong person in a Phoenix-area business can cost you more than the loss itself. That hesitation is normal. It’s also where a lot of the money goes. Below, we walk through five signs it’s time to bring in an outside corporate investigator, what to do while you’re still deciding, and how the process works for businesses across Phoenix, Mesa, Scottsdale, and the rest of Maricopa County. First, why timing matters so much.
We’re an outside, licensed professional team you hire to find out what’s really happening inside your business: who is taking inventory, where money is going, whether a claim is genuine. The work ends in a documented record you can use to end someone’s employment, pursue a civil case, or hand to police.
Timing is the reason we start here. According to the ACFE’s 2026 Report to the Nations, a typical fraud runs about 12 months before anyone catches it, and the median loss is $104,000. Organizations lose roughly 5% of revenue to fraud each year. Analysis of that same report shows cases caught within six months had a median loss around $40,000, while schemes that ran five years or more passed $1.1 million. The year slips by because each sign looks small on its own.
The first sign is the one most owners notice first: inventory, cash, or financial records stop reconciling. A shelf count is off by a little, then a little more. An invoice doesn’t match what actually came in. A margin that held steady for years starts sliding, and nothing in your market explains it.
Any one of these can be a clerical mistake, and we start from that assumption rather than from guilt. When the gap repeats, grows, or the explanations keep changing, it has stopped being a bookkeeping question.
The second sign is about people instead of paper. The ACFE found that 84% of fraudsters showed at least one behavioral red flag, and 43% of frauds were uncovered by a tip, with more than half of those tips coming from employees. So when a staff member quietly mentions something about a coworker, or someone starts guarding records they used to share freely, take it seriously. Don’t act on it yet. Just don’t file it under gossip either.
The third sign is a workers’ comp or insurance claim that doesn’t add up. Maybe the timeline of the injury keeps shifting, or the paperwork tells a different story than the person does. You need proof before you pay or fight, and a hunch won’t carry that weight with an insurer or in front of a judge. Insurance investigations are part of what we do, and our work is documented and done within Arizona law, so what we gather can actually be used.
The fourth sign is that confidential information, clients, or money are walking out the door. A competitor seems to know your pricing before you send a bid. A longtime client suddenly goes quiet. Funds have moved through accounts you can’t explain.
When money has gone into online accounts or digital assets, we trace where it went and document the trail. The FBI’s 2024 Internet Crime report put reported losses at $16.6 billion nationally, with cryptocurrency involved in about $9.3 billion of that, and the Common Sense Institute, citing FBI data, counts $392 million in cyber-enabled crime losses in Arizona alone. We won’t promise anyone their money back. What we can do is show you where it went, and we confirm the scope of that work with you up front.
The fifth sign is the hardest to admit: you can’t investigate this impartially. The person you suspect might be a manager you promoted, a friend of fifteen years, or someone your HR lead plays golf with. The same goes for a deal you’re about to sign with a partner, vendor, or key hire you don’t know much about. Untrained questioning can taint evidence and put you at risk of a lawsuit.
This is the case for an external corporate investigator. We have no loyalties inside your building, so we follow the facts wherever they go, including when the answer is uncomfortable or turns out to be nothing. Attorneys and insurers also bring us in for exactly this reason.

Maricopa County has about 4.69 million residents and 109,863 employer establishments, and Phoenix added 11,793 people in the year to July 2025. That’s a lot of new hires, new vendors, and new money moving around. It’s also the market we’ve worked in for over 20 years.
An investigation starts with a free, confidential consultation where you tell us what you’re seeing. From there we agree on scope, gather facts without assuming anyone is guilty, and document everything as we go. What you end up with is a record that supports a decision: termination, civil litigation, or a referral to the Phoenix Police Department’s Financial Crimes Detail.
Fewer moves are better right now, and the first one is to hold off on confronting anyone. A confrontation gives a person time to delete files, shift stories, or lawyer up before you know what you’re dealing with. It can also put you in the position of having accused someone you can’t yet prove anything against.
Next, preserve what exists. Leave records, emails, logs, and video exactly where they are, and don’t tidy anything up. Write down what you’ve noticed, with dates, so your memory isn’t the only record. Keep the circle small, too. The fewer people who know you’re looking, the less likely the issue gets back to the person involved.
Then talk to your attorney about what you can and can’t do on your own. We stay inside Arizona law so the evidence holds up, and we’d rather you run your plan past counsel than guess. If you don’t have an attorney, we can talk through where one would fit.
After that, call. Our founder, Jeff Penrod, spent years on Phoenix streets as a police officer, and our team includes former Phoenix PD and former military investigators. That background gives you a detective’s view of whether you have a case and how a prosecutor or attorney would want it built. On the first call we’ll tell you honestly what we can do. Sometimes that includes telling you that you can solve it without hiring us. We’d rather say that than take your money for work you don’t need.
Is the city of Maricopa in Maricopa County? No. The city of Maricopa sits in Pinal County, south of the Phoenix metro, and it’s grown fast, reaching 76,654 residents in 2024 and adding another 4,894 in the year to July 2025. Maricopa County is the larger area that includes Phoenix, Mesa, Scottsdale, Chandler, Tempe, Glendale, and Peoria. We serve the Valley from our Phoenix office on North Central Avenue and our second office in Mesa, and we cover the whole state, so wherever your business sits in the Phoenix area, you’re welcome to call.
Is it legal to investigate my own employees? In general, yes, if it’s done properly. We work within Arizona law so the evidence is usable, and we recommend talking to your attorney before you start on your own.
How do I know the investigator is licensed? Arizona licenses private investigators through the Department of Public Safety, and you can verify a license there. Ours is PI License No. 1547944. The agency’s qualifying party must also have at least three years of documented, full-time investigative experience under A.R.S. § 32-2422.
How much does it cost? It depends on scope: what you need answered, how many people and records are involved, and how much time that takes. We don’t publish a price list, and we lay out scope and pricing with you before work begins.
What if it turns out to be nothing? Then you’ve got an answer instead of a lingering doubt, and nobody was accused of anything they didn’t do.
If your numbers won’t reconcile, someone’s behavior has changed, a claim doesn’t add up, information is leaking, or you’re too close to handle this fairly, you’re likely past the point where waiting helps. The data is plain on this: the longer a problem runs, the more it costs, and good evidence is easier to build when it’s still fresh.
