How a store can avoid losing money on mis-sorted items and write-offs

Revenue is stable, but there’s never enough money in the account—sound familiar? It’s rarely a one-time theft. More often than not, two subtle processes are to blame: inventory miscounts and write-offs that no one properly documents. It’s not hard to spot them if you know where to look.

Where does mis-picking come from, and why is it hard to spot?

Imagine this: during a store inventory, a pair of size 41 sneakers is missing from a shoe store, but there’s an extra pair of the exact same model on the shelf—only in size 42. This is what a stock discrepancy is: suddenly, a shortage of one item is found right next to a surplus of another, usually one that’s similar in type, color, or size.

At first glance, it doesn’t seem like a big deal: taken together, the numbers seem to add up. But behind this, there’s almost always someone’s mistake—someone rang up the wrong SKU at the register, or the stock clerk mixed up similar items during inventory, and until these errors are documented, they’ll keep happening.

Write-offs: When It’s Normal, and When It’s Not

From time to time, merchandise in any store gets damaged in transit, breaks, or simply expires, and writing off such items is perfectly normal. In and of itself, such a loss doesn’t necessarily mean anything is wrong.

The problem isn’t the write-off itself, but how it’s documented. A proper write-off always has a reason, a written record, and the signature of the person responsible. But when, month after month, something vague appears in the log without any details, it’s time to be wary. Such vague entries often hide either theft or accounting errors that simply no one has looked into.

Inventory checks catch problems while they’re still small

The easiest way to catch misclassifications and shortages in time is to regularly reconcile accounting data with what’s actually on the shelves. The less often a store does this, the later it notices discrepancies—and by then, it has to guess where they came from.

According to the formal classification, inventory counts are divided into scheduled and unscheduled (surprise) counts. Scheduled counts are arranged in advance, for example, on the last day of the month. Unscheduled inventory counts happen unexpectedly: there’s a suspicion of theft, the employee responsible for the merchandise has changed, or an unexplained figure has appeared in the reports. In practice, this is often supplemented by a spot check of a specific shelf to quickly verify a suspicion without bringing the entire store to a halt.

What Really Reduces Risk

A few simple measures help here: a unique barcode on similar items prevents confusion at the register before it even has a chance to occur; limited access by sales associates to inventory makes it harder to conceal missing items; and requiring a reason for canceling a sale prevents mistakes from being swept under the rug.

This works best when inventory is tracked not by a person in a notebook or Excel spreadsheet, but by a system that automatically records every movement of merchandise. For example, Poster’s user-friendly store management software with inventory tracking displays stock levels in real time and allows you to conduct inventory counts by barcode instead of manual counting. This way, discrepancies are visible immediately, rather than after the fact, a month later.

So what does all this mean?

No inventory system can completely eliminate human error. That’s just not possible. But it makes errors visible right away, while the cost of the mistake is still small, rather than a month later, when an unexplained shortfall has already appeared in the cash register.
