Cycle count: counting stock continuously instead of once a year

Cycle counting is the practice of counting a small part of your inventory on a regular schedule, so that everything is counted over a period, instead of counting everything at once. A shop with two thousand lines might count forty a day; over a quarter, the whole range is covered without ever closing.

The argument for it is not primarily convenience, though it is more convenient. It is that a variance found in March, in a product counted last month, has a traceable cause — a delivery, a return, a specific week. The same variance found in the annual count has twelve months of possible explanations and therefore none, which is why annual counts correct errors without ever fixing them.

Deciding what to count and how often

• By value: classify lines into roughly three groups, where a small share of lines carries most of the value. Count the high-value group monthly, the middle quarterly, the tail once or twice a year.
• By movement: fast-moving lines drift faster and deserve more frequent counts regardless of value.
• By trouble: anything that produced a variance last time gets counted again sooner. Errors cluster.
• By event: count a line when something happened to it — a big delivery, a return, a promotion, a supplier change.
• Everything at least once a year, so the annual position is still supported by a count.

Running it

1. Fix a daily or weekly slot, small enough that it actually happens — twenty minutes at opening beats two hours on a Friday.
2. Generate the day's list from the schedule rather than choosing on the spot, so nobody counts only the easy shelves.
3. Count blind, without the expected figure, for the same reason as in a full stocktake.
4. Record the variance immediately, including zero variances. A count that found no difference is information about the process working.
5. Investigate anything above a threshold you set in advance, by value rather than by unit count.
6. Adjust the records and note the cause. Adjusting without recording why converts a fixable process problem into a permanent monthly ritual.

Track count accuracy as a percentage over time — the share of counted lines that matched. That number is the actual output of the programme, more than any individual correction. Accuracy climbing from eighty to ninety-five per cent over two quarters means the underlying process is improving; a flat number means you are correcting the same errors forever without addressing what causes them.

What it replaces, and what it does not

In many jurisdictions and for many auditors, a well-documented cycle counting programme with good accuracy can substitute for the annual full count — but that is a conversation to have with your accountant before you stop doing the annual one, not after. What cycle counting does not replace is the tidy-up and the discipline: it works only if the schedule is followed, and a programme abandoned in a busy month leaves you with neither approach. The full-count version is covered in stocktake.

Counting is easier when the paperwork already points at locations. A picking list sorted by location, rather than by order line, keeps bins tidy and makes discrepancies easier to trace to a specific pick.

A value applied to the wrong quantity is precise and wrong. Inventory valuation has to rest on a counted figure, which is why the count and the costing belong next to each other.

Where it lives

Ettex Records holds the schedule, the count history and the variance record per line, which is what makes the accuracy trend visible at all; the arithmetic sits in Ettex Sheets and the valuation flows to Ettex Books. The ongoing stock position itself is inventory management.

The boundary: no barcode scanning, no handheld devices, no automatic count list generation from movement data. The schedule is one you maintain, which for a few thousand lines is a spreadsheet-sized problem and above that is a system-sized one.
