Cycle Counting
By the Supply Chain Manager team · Updated October 16, 2026
Cycle counting checks stock accuracy by counting a small set of locations or SKUs every day or week, so the whole warehouse is covered on a rolling basis.
It replaces or reduces the annual shutdown stocktake. Because counts are small and frequent, errors are found close to when they happened, when the cause is still traceable. Many teams count A items more often than C items.
Counts can be scheduled by class (A items more often), by location (every aisle in turn) or triggered by events, such as a bin reaching zero or a picker reporting a shortage. Event-based counts are cheap because the bin is empty or nearly empty, which makes it quick to check whether the system agrees.
Cycle counting example
Illustrative: a warehouse with 3,000 SKUs counts A items monthly, B items quarterly and C items twice a year, which works out to a few dozen counts a day, done in the quiet hour before afternoon picking.
Why cycle counting matters for distributors
Every replenishment number depends on on-hand stock being right. Cycle counting keeps it right continuously instead of once a year.
Common cycle counting mistakes
- Correcting the count without investigating why it was wrong.
- Counting while stock is moving, which creates false variances.
