How to Handle Staff Who Give Excuses for Missing Stock

Almost every shop owner has heard some version of the same four excuses when a stock count comes up short. Some of them are true. The trouble is telling which, and most owners end up guessing — which either lets real theft slide or accuses an honest employee of something they didn't do.

A missing carton of stock rarely gets a shrug. It gets an explanation, and the explanation is usually one of a handful of familiar ones. None of them are inherently false — customers really do shoplift, suppliers really do shortchange deliveries, people really do miscount. The problem isn't that these excuses are always lies. It's that without records, you have no way to tell a legitimate explanation from a convenient one, and guessing wrong in either direction costs you — either you let real theft continue, or you damage trust with someone who was telling the truth.

The excuses you'll hear most often

"Customers must have stolen it"

Shoplifting is real and shouldn't be dismissed outright, but it's also the easiest excuse to reach for because it's nearly impossible to disprove after the fact. The question to ask isn't whether shoplifting happens — it does — but whether the pattern fits. Random shoplifting tends to hit small, easily pocketed items inconsistently. If the "shoplifting" is concentrated on the same product category, disappearing in quantities too large to walk out unnoticed, or happening repeatedly on the same person's shifts, the explanation stops fitting the pattern.

"The supplier shortchanged us"

This one is genuinely common and worth taking seriously, but it's checkable. Compare the delivery note or invoice against what was actually counted onto the shelf at the time of delivery, not weeks later. If deliveries are consistently short specifically when one attendant receives them, and not when someone else does, that's a pattern worth a closer look regardless of what's written on the invoice.

"I must have miscounted"

Miscounts happen, especially with manual tallying on a busy day. But an honest miscount is usually small and doesn't repeat. A "miscount" that's large, or that shows up on the same person's counts week after week, isn't really a miscount anymore — it's a pattern wearing a miscount's excuse.

"It was already missing before my shift"

This is the hardest one to resolve without records, because it shifts responsibility to whoever had the previous shift — and if nobody photographed or logged the count at handover, there's genuinely no way to know who's right. This excuse is exactly why a count at the start and end of every shift matters: without it, this explanation can never be disproven, which means it can always be used.

Why "he said, she said" never actually resolves anything

Every one of these excuses, without records, comes down to one person's word against a number that appeared on its own with no context. That's not a fair position for anyone — the honest employee has no way to prove they're telling the truth, and the owner has no way to confirm they aren't. Arguments like this tend to end with whoever's more convincing or more senior winning, which teaches staff that the way to survive a shortage is to argue well, not to be honest.

The questions that separate a real explanation from deflection

  1. Does the timing match? A supplier shortage should show up the moment stock is received, not weeks later when a count happens to catch it.
  2. Does it happen on this person's shifts specifically, or is it spread evenly across everyone?
  3. Is the size of the shortage consistent with the explanation? A handful of missing sweets fits shoplifting; a missing carton usually doesn't.
  4. Does the same excuse recur for the same person, or is it a one-off?
  5. Is there a record — a photo, a count, a delivery note — that can actually confirm or rule out the explanation, or is it just a claim?

Using shift records instead of guessing

The honest answer is that most owners can't reliably tell a true excuse from a false one just by listening to it — good liars and honest people can sound identical when they're both under pressure to explain a shortage. What actually settles it is a record from before the conversation even starts: a photo of the shelf at the start and end of each shift, tied to whoever was verifiably clocked in at the time. This is the specific gap Shelfie is built to close — the AI count from the photo shows exactly what was on the shelf at handover, and it's tied to the attendant who was face-verified as being on shift, so when an excuse comes up, there's already a record to check it against instead of having to take anyone's word for it, including your own gut instinct.

When to let it go, and when to act

A single short count with a plausible explanation and no repeating pattern usually isn't worth a confrontation — treat it as normal operational noise and move on. What justifies action is a pattern: the same excuse, the same person, the same category of stock, repeated over weeks. At that point, stop asking for another explanation and have a direct conversation grounded in the record rather than the excuse. Most people, confronted with a consistent pattern backed by actual counts, stop offering new excuses fairly quickly — the ones who keep insisting despite the pattern are telling you something too.

Frequently asked questions

How do I know if an employee is lying about a stock shortage?

You usually can't tell from the explanation alone — plausible-sounding excuses and honest ones can sound the same. What works is comparing the excuse against records: does the timing, size, and pattern of the shortage actually match what's being claimed, and does it keep happening on the same person's shifts.

Is it normal for staff to blame customers for missing stock?

It's a common explanation and sometimes accurate, since shoplifting does happen. It becomes a red flag less because of the explanation itself and more because of the pattern — if it's used repeatedly for the same product categories or the same shifts, or for quantities too large to plausibly walk out unnoticed, it's worth investigating rather than accepting at face value.

What should I do if a supplier and an employee blame each other for a shortage?

Compare the delivery note against a count taken at the actual moment of delivery, not weeks later. If the shortfall shows up consistently with one supplier regardless of who receives it, that points to the supplier; if it only shows up when one specific attendant receives the delivery, that points the other way.

How can I prove who was responsible for a stock shortage without accusing the wrong person?

Tie stock counts to verified shifts — a photo or count at the start and end of each shift, matched to whoever was actually clocked in, not just scheduled. That turns the question from a guess about who's more believable into a comparison of records, which is fair to everyone involved.
