Quick answer
Register theft is rarely caught by one big moment. It's identified by patterns — repeated variance on the same shift, elevated voids by one cashier, no-sales that don't match the day's flow. The goal of this guide isn't to help you accuse anyone. It's to help you see, document, and act the right way, in the right order.
Important — read this first
This article is about identifying patterns, not accusing people. Nothing in here is legal advice. Before any formal action against an employee, consult an employment attorney in your jurisdiction. False accusations create more damage than the original loss.

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:

  1. Observe — count drawers, log variance, and review transactions every single shift.
  2. Track patterns — by cashier, by shift, by transaction type.
  3. Document — every count, variance, void, and refund. No memory.
  4. Coach early — most issues stop when the cashier realizes leadership is paying attention.
  5. 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.

Important caution
Behavioral signs alone are never sufficient. Many honest employees show several of these for completely innocent reasons. Behavioral signs are a reason to look at the transaction data, not a reason to confront anyone.

Transaction indicators

This is where most actual evidence lives.

Transaction typeWhat to watch forWhy it matters
VoidsCashier with disproportionate voids vs team average; voids after sale completed.Classic skim: ring sale, take cash, void after customer leaves.
No-salesFrequent no-sales without legitimate reason (change-making, drawer adjustment).No-sales open the drawer with zero paper trail.
Refunds without receiptsRefunds 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 discountsFriends-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. receiptMultiple identical items rung as one (under-ringing).Customer pays for less than they receive; cashier may collect the difference later.
End-of-day varianceRepeated 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.

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

  1. Unscheduled but predictable in frequency. Cashiers should know audits happen, just not exactly when.
  2. Two people. Cashier counts, manager verifies. Always two.
  3. Counted against the POS expected balance, not a guess.
  4. All variance documented, not just amounts over a threshold.
  5. Variance reviewed with the cashier same shift — calm conversation, not interrogation.
  6. 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.

A defensible investigation workflow

This is not a do-it-yourself guide
The workflow below is how trained loss prevention professionals approach a developing situation. For meaningful incidents, involve a qualified LP professional and an employment attorney before any interview or formal action.
  1. Pattern recognition phase. Variance + transaction anomalies + behavioral indicators logged over multiple shifts.
  2. Quiet confirmation phase. Pull POS data, compare to expected behavior, identify specific incidents to review.
  3. Video review. Targeted, not broad. Specific transactions, specific times, preserved on separate media.
  4. Evidence preservation. Lock down transaction logs, schedules, audit sheets, and video. Do not delete or overwrite anything.
  5. Professional consult. Loss prevention professional, employment attorney, or both before any conversation with the employee.
  6. Interview (if appropriate). Conducted properly, with the right people, in a way that protects both the employee and the business.
  7. Resolution. Termination, restitution, prosecution, or coaching — supported entirely by documented evidence.

Video review guidance

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.

SituationResponse
Single small variance, no patternCoaching conversation. Document and move on.
Repeated small variance, single cashierTargeted retraining + closer audit cadence.
Variance + elevated voids/refunds by same cashierQuiet pattern review. Pull POS data. Do not confront.
Variance + behavioral indicators + transaction anomaliesStop 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

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

If you see this, stop and get help
  • 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.
Continuing alone risks ending the case, exposing the business to legal liability, and damaging team trust.

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.

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.
