You can’t prove it, but you can feel it. The numbers are off. Stock runs out faster than the sales explain. Cash at the end of the day is short by a few thousand Naira more often than it should be. And the staff member you trusted to mind the counter while you ran errands keeps giving you that slightly-too-quick answer when you ask about it.
You don’t want to think it. But you’re thinking it. Is somebody stealing from me?
Here’s the hard part. Suspicion alone is poison. You start watching everyone. You count stock twice a day. You ask questions in a tone that makes good staff feel accused. And you still don’t know, because watching people has never once produced proof.
The problem was never that you needed to watch harder. The problem is you have no record of who did what.
The signs that something is off
Most shop owners don’t catch theft. They catch the shadow of it, weeks later, and only because the gaps finally got big enough to notice:
- You restock a product, and it’s gone again far sooner than your sales suggest it should be.
- The till is short at closing, not every day, but often enough that “miscounting change” stops being a believable explanation.
- A customer mentions she bought something last week. You check. There’s no record of that sale anywhere.
- Returns and “damaged goods” creep up, all logged by the same person, always when you weren’t around.
None of these prove anything on their own. A till can genuinely be short from bad change. Goods do get damaged. But when you can’t tie any of it back to a specific transaction, a specific time, and a specific person, every gap becomes a mystery you’ll never solve. So it keeps happening.
Why “just watch them” never works
You can’t be at the counter every hour your shop is open. That’s the whole reason you hired help. The moment you step out to see a supplier or handle the bank, the record of what happened in your absence lives entirely in one person’s memory and one person’s honesty.
And even when you’re there, you can’t watch a busy counter and catch the small things. The sale that gets rung at the wrong, lower price with the difference pocketed. The item handed over without being entered at all. The “discount” given to a friend. These don’t look like theft in the moment. They look like a normal Tuesday.
Watching harder just makes you tired and makes your staff resentful. What you need is for the shop itself to keep the record, automatically, on every single sale, whether you’re standing there or not.
First, be fair: not every gap is theft
Before you accuse anyone, understand that real shrinkage has several causes, and only one of them is a dishonest staff member:
- Honest mistakes — a sale entered at the wrong quantity, a price typed wrong, change miscounted.
- Forgotten entries — a busy rush where two or three sales never made it into the record at all.
- Breakage and spillage — bottles dropped, products decanted with loss, goods damaged in storage.
- Undercharging — staff guessing a price instead of checking it, costing you margin on every sale.
- Actual theft — stock or cash leaving without a matching transaction.
If you accuse a staff member and the real cause was a pricing mistake, you’ve damaged a good working relationship over nothing. This is exactly why guessing is dangerous. You need to know which one it is. And you can only know that if every transaction leaves a trail.
What you actually need: a record of who did what
You don’t need a security guard or a camera over every shelf. You need four things working together.
1. Every sale tied to the person who made it. When each transaction records who rang it up, the date, the time, and the exact items, your shop stops being a mystery. You can see that 40 sales went through on Saturday, and exactly who served each one. If a customer says she bought something and there’s no record, you know who was on the counter at that hour.
2. Stock that deducts automatically with every sale. When stock drops the instant a sale is rung, a missing item shows up the same day, not three weeks later during a panicked count. The gap between a loss and noticing it is where theft hides. Close that gap and there’s nowhere to hide. We wrote about how this catches losses early in 5 ways Nigerian shop owners lose money without knowing.
3. Roles that limit what each person can see and do. Your sales attendant needs the counter. She does not need to see your supplier costs, your profit margins, or your reports. When staff can only reach the POS, and only an owner can change a price, delete a sale, or approve a stock adjustment, you’ve removed most of the opportunities for quiet manipulation. Give people exactly the access their job needs, and nothing more.
4. A trail on the risky actions. Voids, returns, price overrides, stock adjustments. These are the moves that can be used to cover a theft. When every one of them is logged, with who did it and when, the pattern becomes obvious. Three voids a week from the same person, always at closing time, is a conversation. One void with a clear reason is just a normal correction.
How this changes the conversation
This is the real shift. When the shop keeps the record, you stop accusing people and start asking the record questions.
Instead of “I think you’re stealing from me,” which no honest person can prove false and no dishonest person will admit, you get to say: “There are six sales of this product with no payment recorded, all from last Thursday. Walk me through what happened.” That’s a specific question about a specific gap. It’s not personal. It’s not a vibe. It’s the data.
Nine times out of ten, that conversation resolves something small and fixable, a training gap, a pricing mistake, a forgotten entry. And the one time it doesn’t, you finally have what suspicion could never give you: proof.
It protects your honest staff too
Here’s what gets missed. The staff member who isn’t stealing is the one most damaged by your suspicion. She’s working hard, she’s honest, and she’s living under a cloud of “the boss thinks somebody’s a thief” with no way to clear her name. When the shop counts as proof of every transaction she made, she can point to her record and stand on it. Every sale she rang, every Naira she collected, all there. A proper record doesn’t just catch the dishonest. It defends the honest, and your best people will respect a shop that runs on records instead of accusations.
Stop guessing. Start knowing.
You hired help so you could grow your business, not so you could spend every day suspicious of the people working for you. The way out isn’t to trust blindly or to watch obsessively. It’s to let your shop keep an honest record that answers your questions for you.
Mayloo ties every sale to the staff member who made it, deducts stock automatically so gaps show the same day, and gives your team role-based access so the counter staff sees the POS and nothing else. Voids, returns, and adjustments are all logged, who did it and when. So the next time the numbers feel off, you don’t accuse anyone. You check the record.
