Most shops count stock once a year, close for two days to do it, and end up with a figure nobody entirely believes. There is a better way, and it does not involve shutting the shutter.
Why the annual count fails
By the time you have counted ten thousand items, the ones you counted first have moved. Staff are tired, the shop is closed, and everybody wants it finished, so the last few aisles get estimated.
Then the difference between the count and the system is too large to investigate, so it gets adjusted away and nobody learns anything.
Count a section at a time
Pick one category a week and count it properly during a quiet hour. Compare it against what the system expects. A difference in one category is small enough to actually look into.
Over a quarter you will have counted the whole shop, in hours nobody missed, with differences you had a chance to explain.
- Count fast movers more often than slow ones
- Count high-value items most often of all
- One category at a time is investigable
What the differences tell you
A consistent shortfall in one small, valuable category is a different problem from a scatter of small differences across everything. The first is worth watching closely. The second is usually billing errors and breakage.
You only learn the difference between them by counting often enough to see a pattern.
Adjust, and record why
When you correct a figure, record the reason: damaged, expired, missing, or a billing error found. An adjustment with no reason is a hole in the record, and holes accumulate.
Six months of reasons is a report about how your shop actually loses stock, which is worth more than any single count.
The goal is not a perfect number once a year. It is a number you trust all year.
