Cycle counting: how to count stock without shutting down
Cycle counting checks a slice of inventory on a rolling schedule. Learn how to choose what to count, how often, how to handle differences and how it beats annual stocktakes.

Cycle counting means counting a small part of your inventory every day or week, so that over a year everything is counted, some of it several times. It replaces the all-hands annual stocktake with a steady habit that finds problems while they are still small and traceable.
Key takeaways
- Count a few locations or products often instead of everything once.
- Count the products that matter most, or are most likely to be wrong, more often.
- Investigate the cause of every difference, not just fix the number.
- The goal is accurate records, so picking and ordering are reliable.
Why not just count once a year?
An annual count finds that stock is wrong long after the mistakes happened, so nobody remembers why. It often needs trading to stop. Meanwhile, wrong numbers cause oversells, missed reorders and wasted picks all year. Counting regularly shortens the gap between a mistake and its discovery.
How to choose what to count
- By ABC class. Count A items (the products that make most of your revenue) monthly or more, B quarterly, C twice a year. See ABC analysis.
- By location. Walk the warehouse in order, a few bays a day.
- By trigger. Count when stock shows zero but a pick was attempted, after a large adjustment, after receiving a big delivery, or when a product is low and about to be reordered.
- By error history. Items with frequent differences get counted more.
A simple routine
- Generate the day's count list.
- Count blind where you can. Do not show the system quantity, or counters will agree with it.
- Recount any line with a difference before adjusting.
- Record the adjustment with a reason (miscount, damage, wrong pick, receiving error, theft).
- Review reasons weekly. Patterns point to a process fix.
Measuring accuracy
Track the share of counted lines that matched exactly, and the net and gross value of differences. Gross matters because overages and shortages can cancel out. A rising accuracy rate shows your processes are improving; a flat one means you are fixing numbers, not causes.
Cycle counting and the stock ledger
Every adjustment should leave a trail: what changed, by how much, why, and who did it. That is what lets you answer "where did these 12 units go?" See the stock ledger and stock ledger audit trails.
How Stokrio helps
Stokrio records every stock change in an append-only ledger with its type, source, person and balance after, so count differences are traceable. It covers multiple warehouses and locations. For 3PLs, count differences by client appear in the 3PL reports, fed through the Partner API.
