A blind stock count hides the expected figure.
A blind stock count is a physical count where staff record what is on the shelf without seeing what the system expects, so the count cannot drift toward the number on screen.
How we use it.
In Keystone OS staff scan and count without seeing the system figure. The manager then reviews the variance and applies corrections, and each correction is written to the stock ledger with the quantity before and after.
We built it for a retailer with three shops and an online channel, where 8,300+ stock movements have been reconciled with zero mismatches. The blind step is what makes a variance worth believing.
One jacket, one variance (fictional)
Staff at a fictional store scan 40 units of a jacket in size M.
They never see the system figure, which is 43.
The manager sees a variance of 3 and checks recent transfers and returns.
The correction posts to the ledger with its reason, so the next count starts clean.
Common mistakes
- Showing counters the expected number, which turns a count into a confirmation.
- Correcting the figure with no reason recorded.
- Counting while sales and transfers are still moving the same stock.
