Direct answer. Cycle counting is a physical stock-counting method that consists of regularly checking only a portion of the references, by zone, family or ABC class, rather than counting the entire stock all at once. It keeps stock accuracy high on a continuous basis, with less impact on operations than a full annual inventory.
Counting continuously rather than once a year
Unlike an annual inventory, which often shuts down the warehouse for one or more days for an exhaustive count, cycle counting spreads counts across the year on a recurring schedule. The most common approach relies on ABC classification: A references (high value or turnover) are counted more frequently, sometimes every month, while C references (low priority) are reviewed only a few times a year. Other warehouses organize their cycles by storage zone or product family, ensuring every location is visited at least once over the reference period.
The main benefit of the method is to quickly detect discrepancies between theoretical and physical stock, and to correct the cause before it repeats on other references. Well-run cycle counting is also a tool against unexplained inventory loss (shrinkage), since it identifies recurring discrepancies (picking errors, theft, undeclared breakage) earlier than a single annual check. It does not necessarily remove the need for a full physical inventory at fiscal year-end depending on a company's obligations; the two approaches are generally complementary.
FAQ
What is the difference between cycle counting and an annual inventory?
An annual inventory counts the entire stock at once, often by halting activity. Cycle counting spreads the counts over the year, by zone or by reference, without shutting down the whole warehouse. The two methods are often complementary rather than mutually exclusive.
How often should cycle counting be performed?
Frequency generally depends on each reference's ABC class: high-value or fast-moving items (class A) are counted more often, sometimes monthly, while low-priority items (class C) are reviewed only a few times a year.
How do you organize cycle counting with the ABC method?
The ABC method classifies references by value or logistical importance (A, B, C), then sets a decreasing counting frequency for each class. This targeting focuses counting effort where stock discrepancies have the greatest economic impact.
