Addressing, barcodes, counting methods and reporting: what stock tracking actually looks like on the warehouse floor.
Stock tracking in a warehouse is the application on the floor of rules defined on paper. Below are the practices that make up the daily rhythm of a warehouse that works.
The addressing scheme
The warehouse divides into aisles, aisles into racks, racks into bins. Every bin gets a unique code — for example A-03-02-B. The moment an item is placed there, it is recorded in the system. The picking list can then route the operator to the right bin by the shortest path.
Scanning
Every scan on a handheld terminal produces a movement record. At goods receipt the item and the address are scanned; at picking the item and the order are scanned; at dispatch the carton is scanned. Once those three scan points are respected, record accuracy rises on its own.
Counting methods
- Periodic stocktake: counting the whole warehouse at intervals — usually requires halting operations
- Cycle counting: counting specific addresses every day — no downtime, and errors are caught early
- Spot check: a targeted count triggered by suspicion of a variance on one item
In practice the most effective approach is to use cycle counting as the primary method and run one annual full count purely for verification.
Reporting and correction
When a variance appears, the point is not to correct the number but to find its cause. Was it a mis-addressed put-away, an unscanned outbound, a faulty goods receipt? A correction made without finding the cause simply invites the same variance back a month later.
