Cycle Counting
Definition
The practice of counting a small subset of inventory locations or SKUs on a rotating schedule instead of shutting down for a full physical inventory. Discrepancies are investigated and corrected continuously.
In Practice
Cycle counting replaces the disruptive annual wall-to-wall count with a steady rhythm of small counts. Items are typically scheduled by ABC class, so high-value A items may be counted monthly while C items are counted once or twice a year. Each variance is reconciled and, critically, root-caused so process errors get fixed.
For planners, the payoff is trustworthy system data. Reorder points, allocations, and available-to-promise calculations all assume the on-hand number is real; cycle counting is what keeps that assumption honest and keeps inventory accuracy above the level where planning systems can be trusted.
Example: a warehouse counts 60 locations per day before first shift. When a count finds 12 units instead of the 20 on record, the team traces the gap to a mispicked transfer order, corrects the record, and retrains the picker, preventing a phantom stockout on the next customer order.

The degree to which recorded inventory matches what is physically present, measured by comparing system records to physical counts. It is usually expressed as the percentage of records that match within tolerance.
ABC AnalysisA method of segmenting inventory into classes by value or importance, typically with A items representing the small fraction of SKUs that drive most of the value. It focuses management attention where it matters most.
ShrinkageThe loss of inventory between receipt and sale from causes such as theft, damage, spoilage, administrative error, or vendor fraud. It appears as the gap between recorded and actual stock.
On-Hand InventoryThe physical quantity of stock currently present in a location, regardless of whether it is committed to orders. It is what you would find if you walked out and counted the shelves.
