Signs of register theft and how to prevent it
The register-level signs of theft are repeat shortages tied to one cashier or shift, high counts of voids, no-sale drawer openings and refunds without receipts, and stock that disappears while the drawer still balances. Prevent it with one cashier per drawer, blind counts, manager approval on voids and refunds, and a weekly review of those numbers by person.
How large the problem is
The National Retail Federation's 2023 National Retail Security Survey, based on 177 retail brands covering more than 97,000 locations, put average shrink at 1.6% of sales in fiscal 2022, up from 1.4% in fiscal 2021, and found that internal and external theft together accounted for 65% of shrink. The release does not split employee theft from customer theft. Example: at 1.6%, a store with $800,000 in annual sales would lose 800,000 × 0.016 = $12,800 to shrink of all kinds.
Warning signs you can see in register data
| Sign | Where to see it | How cash leaves | Innocent explanation to rule out |
|---|---|---|---|
| Shorts that repeat with one cashier | Over/short log sorted by cashier | Cash removed from the drawer | Shared drawer, miscounted float |
| Drawer balances but stock is short | Stock count vs units sold | Sale not rung, cash pocketed | Receiving errors, customer theft |
| Many voids after the sale is complete | POS void report by cashier | Sale voided after the customer leaves, cash kept | Training gap on a new cashier |
| Many no-sale drawer openings | POS no-sale report | Drawer opened for an unrung sale | Giving change for another register |
| Cash refunds without receipts | Refund report by cashier and tender | Refund issued with no customer, cash taken | Store policy allows receipt-less returns |
| Discounts or comps on certain shifts | Discount report by cashier | Discount rung, full price collected | A promotion only on that shift |
| Variances only when one person counts | "Counted by" column | Count adjusted to hide a short | That person counts the busiest shift |
Weekly exception report (template)
| Cashier | Shifts | Voids | Voids per shift | No-sales | Cash refunds (count / $) | Discounts ($) | Net over/short |
|---|---|---|---|---|---|---|---|
| Cashier 1 | 5 | 12 | 2.4 | 3 | 1 / $18.00 | $6.50 | −$1.20 |
| Cashier 2 | 4 | 3 | 0.75 | 2 | 0 / $0.00 | $4.00 | +$0.30 |
| Store | 9 | 15 | 1.67 | 5 | 1 / $18.00 | $10.50 | −$0.90 |
Example math: Cashier 1 has 12 voids in 5 shifts = 2.4 per shift; the store has 15 voids in 9 shifts = 1.67 per shift. One week above average is a question, not a finding. Look at the same report for four weeks, and read the voids themselves (time, amount, whether a manager approved).
Controls that close the gaps
| Control | Closes | What it costs |
|---|---|---|
| One cashier per drawer per shift | Shorts with no name attached | A drawer swap and count at shift change |
| Blind closing counts | Counts adjusted toward the target | A second person compares, same night or next morning |
| Manager approval on post-sale voids, refunds and no-sales | Void-and-pocket, fake refunds | Manager time at the register |
| Receipt to every customer, every sale | Unrung sales (the customer expects a receipt) | Paper or an emailed receipt |
| Regular stock counts on high-theft items | Unrung sales that balance the drawer | Counting time per week |
| Cash drops to the safe above a set limit | Large amounts sitting in the drawer | A few minutes per drop |
| Written cash handling policy, signed | "Nobody told me" disputes | One page |
If the numbers point at one person
- Write down the dates, registers, amounts and report lines. Facts only.
- Rule out the innocent explanation in the table above for each sign.
- Check who was actually on the register: shift and clock-in records, not the schedule.
- Talk to the employee with a second manager present. Ask; do not accuse.
- Get advice from an employment lawyer before discipline, a police report or any pay deduction.
On deductions: the US Department of Labor's Fact Sheet #16 (revised July 2009) lists a minimum wage cashier required to reimburse the employer for a cash drawer shortage as an example of an illegal practice; a deduction may not bring pay below the $7.25 federal minimum wage or cut into overtime. State rules can be stricter. This is general information, not legal advice. Check your state labor department for current rules.
For step 3, Assistlify's clock in/out records (with an attendance CSV export) show who was working each shift at each location. Cross-store patterns are covered in tracking cash variance across multiple stores.
Questions
How do employees steal from a cash register?
The patterns visible in register data are cash removed from the drawer, sales not rung, voids or refunds issued after the customer leaves, and discounts rung while full price is collected.
Can a drawer balance even if an employee is stealing?
Yes. Cash from a sale that was never rung never enters expected cash, so the drawer balances and the loss shows up only in stock counts.
How much do retailers lose to shrink?
NRF's 2023 National Retail Security Survey put average shrink at 1.6% of sales in fiscal 2022, with internal and external theft making up 65% of it.
Can I take stolen money out of an employee's paycheck?
DOL Fact Sheet #16 says a deduction for a cash shortage may not bring pay below the $7.25 federal minimum wage or cut into overtime; state law can be stricter, so get legal advice first.
