Background
Ahmed S. owns three independently branded convenience stores in the Atlanta metro area. Each store operates 24 hours with three shifts per day. Like many multi-unit operators, Ahmed relied on end-of-shift cash counts and monthly reconciliation to monitor financial performance.
The shortages had been present for over two years but were always attributed to normal variance — counting errors, change-making mistakes, and the inherent difficulties of managing cash across 9 shifts per day (3 shifts × 3 stores). No single shift ever showed a dramatic shortage; the losses were distributed across multiple shifts and locations at amounts of $30-75 per shift.
The Problem
Ahmed's losses were the "death by a thousand cuts" pattern that's most difficult to detect. No single event was alarming enough to trigger investigation. But the cumulative effect was devastating:
- Store 1: Averaging $950/month in unexplained cash shortages
- Store 2: Averaging $1,200/month in shortages
- Store 3: Averaging $1,150/month in shortages
- Combined annual impact: Approximately $39,600
Ahmed had installed cameras at all three stores, but nobody was reviewing the footage systematically. The cameras served as a theoretical deterrent but not as an active monitoring tool.
"I knew something was wrong. My P&L showed it every month. But when you look at each shift individually, it's $40 here, $60 there. How do you investigate that? I had cameras but 72 hours of footage per day across three stores. I couldn't watch it all."

The Solution
Ahmed enrolled all three stores in DohShield's Gold plan ($379/month per store, 125 transactions audited daily). DohShield's team connected to Ahmed's existing camera systems and POS data feeds within one week.
What DohShield Reviewed Daily
- All void transactions — correlated with video to verify customer presence and merchandise return
- All no-sale drawer opens — verified on camera for legitimate purpose
- All refund transactions — video confirmation of customer and product
- Safe drop compliance — video verification of drops at required intervals
- Low-dollar and suspicious-pattern transactions flagged by the exception engine
What DohShield Found
Within the first two weeks of daily auditing, DohShield identified a clear pattern:
Store 1: Overnight Void Abuse
The overnight cashier (11 PM - 7 AM) was processing 4-6 voids per shift, all between 1 AM and 4 AM — the quietest hours with no customers in the store. Video showed the cashier voiding completed cash transactions after customers left, then removing the equivalent cash from the drawer. Average theft per shift: $45.
Store 2: No-Sale Cash Removal
A second-shift cashier (3 PM - 11 PM) was opening the drawer via no-sale 8-12 times per shift — significantly above the store average of 2-3 no-sales. Video showed the cashier removing bills during several of these no-sale events, typically $10-20 at a time. To balance the drawer at shift end, the cashier was under-ringing selected cash transactions throughout the shift.
Store 3: Refund Fraud Scheme
A rotating cashier who worked at Store 3 three nights per week was processing phantom refunds — "customer returns" with no customer present. The refund reduced the drawer's expected cash total, allowing the cashier to remove the refunded amount. Video showed the refund being processed to an empty counter.
Results
DohShield produced investigation-ready evidence packages for all three employees, including:
- Timestamped video clips showing each theft event
- Corresponding POS transaction receipts (voids, no-sales, refunds)
- Pattern analysis showing the frequency and timing of each scheme
- Estimated total theft per employee based on documented pattern
All three employees were terminated. Ahmed used the evidence packages to successfully deny all three unemployment claims. Monthly cash shortages across the three stores dropped from $3,300/month to under $200/month (normal change-making variance) within 30 days of the terminations.
"DohShield found in two weeks what I couldn't find in two years. Three employees, three different methods, all hiding in plain sight. The evidence packages made termination clean — no disputes, no lawsuits, no unemployment claims. I'm saving $3,000 a month. The service costs $1,137 for all three stores. That's a 35x return."
