I've sat across the table from a lot of cashiers in investigation interviews. Almost none of them got there because of one dramatic moment. They got there because someone — usually an owner — finally slowed down and looked at the patterns that had been quietly accumulating for months.
That's what this article is. Not a "how to catch a thief" piece. A framework for seeing what's actually happening at your registers, building defensible documentation, and knowing when a situation has graduated from "coaching" to "investigation."
How to actually think about register theft
Most small business owners think about register theft like a snapshot: "Is this person stealing right now?" The right question is closer to: "Is this person showing a pattern that's statistically inconsistent with the team?"
One shortage is noise. Three shortages on the same shift, with the same cashier, paired with elevated voids — that's signal.
The framework I use is simple:
- Observe — count drawers, log variance, and review transactions every single shift.
- Track patterns — by cashier, by shift, by transaction type.
- Document — every count, variance, void, and refund. No memory.
- Coach early — most issues stop when the cashier realizes leadership is paying attention.
- Escalate carefully — only when patterns plus evidence demand it, and only with professional support.
Behavioral warning signs
Behavior alone proves nothing. But behavior plus transaction patterns plus variance starts to tell a story. Watch for combinations, not single moments.
- Cashier consistently insists on working a specific register or shift alone.
- Drawer "doesn't fit right" or is repeatedly reorganized in ways that obscure counting.
- Visible discomfort or topic-changing when refunds, voids, or shortages are discussed.
- Customers being told receipts aren't needed, or printers "running out of paper" unusually often.
- Lifestyle changes that are dramatic and unexplained — not a reason to accuse anyone, but worth noting alongside other indicators.
- Refusal to let another employee count or run the drawer.
Transaction indicators
This is where most actual evidence lives.
| Transaction type | What to watch for | Why it matters |
|---|---|---|
| Voids | Cashier with disproportionate voids vs team average; voids after sale completed. | Classic skim: ring sale, take cash, void after customer leaves. |
| No-sales | Frequent no-sales without legitimate reason (change-making, drawer adjustment). | No-sales open the drawer with zero paper trail. |
| Refunds without receipts | Refunds processed at one register repeatedly, often to the same card or cash. | Common method to pocket cash by 'refunding' a sale that never happened. |
| Manual discounts | Friends-and-family discounts beyond policy; manager override codes used by non-managers. | Sweethearting: discount given to a friend, then cash difference pocketed if customer pays normal price. |
| Item count vs. receipt | Multiple identical items rung as one (under-ringing). | Customer pays for less than they receive; cashier may collect the difference later. |
| End-of-day variance | Repeated overages of small consistent amounts, not just shortages. | Overages often signal voided/refunded sales that weren't actually returned. |
Shortage patterns that matter
The pattern matters more than the dollar amount.
- Same cashier, multiple shifts: highest-priority signal.
- Same shift, multiple cashiers: often a process/scheduling issue, not theft.
- Same register, multiple cashiers: hardware or counting issue first; investigate before assuming intent.
- Small consistent variance: often more revealing than a single large one.
- Variance only on days the manager is off: ownership gap. May be theft, may be process drift, often both.
Till audit methods that surface patterns
Random till audits done correctly do more to prevent register theft than any camera ever installed. Done incorrectly, they punish honest employees and miss the dishonest ones.
What good till audits look like
- Unscheduled but predictable in frequency. Cashiers should know audits happen, just not exactly when.
- Two people. Cashier counts, manager verifies. Always two.
- Counted against the POS expected balance, not a guess.
- All variance documented, not just amounts over a threshold.
- Variance reviewed with the cashier same shift — calm conversation, not interrogation.
- Trended weekly — the daily count creates the data; the weekly trend creates the signal.
Use the free Till Audit & Register Shortage Tracker to make this consistent across shifts.
Documentation that holds up
If you ever need to act on what you've seen, the only thing that matters is what you've written down. Memory does not survive cross- examination.
- Every till count: date, time, cashier, manager, register, expected, actual, variance.
- Every void/refund/no-sale: timestamp, cashier, amount, reason.
- Every coaching conversation: date, topic, employee acknowledgement.
- Any video review: who reviewed, when, what was seen, where footage is preserved.
- Any incident: written narrative completed within 24 hours using a standard incident report template.
A defensible investigation workflow
- Pattern recognition phase. Variance + transaction anomalies + behavioral indicators logged over multiple shifts.
- Quiet confirmation phase. Pull POS data, compare to expected behavior, identify specific incidents to review.
- Video review. Targeted, not broad. Specific transactions, specific times, preserved on separate media.
- Evidence preservation. Lock down transaction logs, schedules, audit sheets, and video. Do not delete or overwrite anything.
- Professional consult. Loss prevention professional, employment attorney, or both before any conversation with the employee.
- Interview (if appropriate). Conducted properly, with the right people, in a way that protects both the employee and the business.
- Resolution. Termination, restitution, prosecution, or coaching — supported entirely by documented evidence.
Video review guidance
- Review specific transactions, not whole shifts. You'll find what you can prove, not what you suspect.
- Confirm camera coverage actually shows the drawer, the hands, and the customer interaction.
- Preserve full clips with audio (where legal). Never edit or extract only "the good parts."
- Document who reviewed, when, and what was observed — same standard as any other evidence.
- Audio recording laws vary by state. Many states require all-party consent. Confirm yours before relying on audio.
Coaching vs investigation — different tools for different problems
Not every variance is theft. The first response to almost every incident should be coaching, not interrogation.
| Situation | Response |
|---|---|
| Single small variance, no pattern | Coaching conversation. Document and move on. |
| Repeated small variance, single cashier | Targeted retraining + closer audit cadence. |
| Variance + elevated voids/refunds by same cashier | Quiet pattern review. Pull POS data. Do not confront. |
| Variance + behavioral indicators + transaction anomalies | Stop investigating informally. Bring in LP professional / attorney. |
| Direct evidence of theft (caught in the act) | Preserve evidence. Do not confront alone. Contact attorney before action. |
False positives — what looks like theft and isn't
- POS reporting errors (especially after software updates).
- Promotion / discount logic configured incorrectly.
- Returns processed at one register because that's how the layout works, not because of intent.
- A cashier protecting another cashier's bad habits — process issue, not necessarily theft.
- Counterfeit currency taken in good faith.
- Customer disputes leading to legitimate refunds that look unusual on a report.
This is exactly why pattern recognition matters. One data point lies constantly. A trend over time is harder to mistake.
When to stop investigating yourself
- Multiple, documented incidents pointing to the same employee.
- Direct evidence (video, customer complaint, witnessed event).
- Restitution or termination is on the table.
- Any situation involving law enforcement, courts, or insurance.
Systemize the pattern recognition
Every workflow in this article — drawer counts, variance tracking, void/refund logs, coaching notes, incident reports — works better when it lives in one place instead of a binder, a phone, and the manager's memory.
That's the entire reason My LP Portal exists: to give small business owners the operational visibility that used to require a dedicated loss prevention team. Pair it with the Till Audit Sheet and the Employee Theft Warning Signs Checklist for a complete starter system.
You are not trying to catch people. You are trying to make the environment one where dishonest behavior is statistically impossible to hide.
Track register counts, variance, voids, refunds, and no-sales in one printable sheet. Built to surface the patterns this article describes.
Frequently asked questions
How do I know if an employee is stealing from the cash register?+
You don't 'know' from a single shift. You build evidence over time by tracking variance patterns by cashier and shift, reviewing voids/refunds/no-sales, comparing transaction logs to video, and looking for repeated indicators — not isolated events. One short drawer is noise. The same cashier repeatedly short on the same shift, paired with elevated voids, is signal.
What are the most common cash register theft tactics?+
The most common patterns small businesses see are: under-ringing items and pocketing the difference, voiding completed sales after the customer leaves, refunding to a personal card, no-sales to open the drawer with no transaction, sweethearting (friends-and-family discounts not approved), and skipping the receipt so there's no paper trail.
Is it illegal for me to review my employee's transactions and camera footage?+
In most U.S. jurisdictions, an owner can review POS transaction logs and on-premises camera footage for legitimate business reasons. Laws vary by state, especially around audio recording and break-room areas. Before any formal action, consult a local employment attorney — this article does not provide legal advice.
Should I confront an employee I suspect of stealing?+
No. Confrontation without documented evidence destroys cases, creates legal exposure, and damages culture. Document patterns first. Use coaching for performance issues. Reserve formal interviews for situations where documented evidence supports them, and consider involving an experienced investigator or attorney before escalating.
What should I do if I'm sure register theft is happening?+
Stop investigating informally. Preserve transaction logs and video. Stop discussing the situation with other staff. Contact an experienced loss prevention professional or employment attorney before taking action. Acting too early — or too publicly — usually ends the case before it starts.
