Several people counting at the same time

When one person counts a large warehouse, the stock count drags on for weeks. What was counted at the start is not where it was by the end: goods are received, dispatched and moved, so the figures go stale. That is why a count should be split among several people and their results gathered into one list. It is not only about speed: figures captured in a short window are much closer to reality.

Estimating the time

A simple calculation helps. Suppose the warehouse holds 6,000 positions and one counter handles about 150 positions an hour. This is only an example: the real speed depends on the type of goods, their layout and the person's experience. One person then needs 40 hours, or five working days. Eight people can finish the same job in a day, in about five hours, leaving time for rechecks and for reviewing differences.

The headcount cannot grow without limit, though. In a narrow aisle two people get in each other's way, and a supervisor cannot keep track of dozens of workers. As a rule, one person in charge copes with no more than 5 to 8 counters.

One more practical rule: match the number of counters to the number of zones. Eight people need eight zones, otherwise two end up in one zone and the risk of double counting, covered below, appears.

How the results merge into one list

Each counter works on their own phone, but the entries flow into a shared list. In a well-organised system every entry stores:

• which item was counted;
• what quantity was entered;
• who entered it and in which zone;
• at what time.

At the end, all entries for one item are added up and compared with the booked balance. One important point: the same item may sit in several places in the warehouse, say 30 units in the picking zone and 200 in reserve. That is normal, and adding them up is right. The dangerous case is when two people count the same spot.

For example, three entries arrive for one article: the first counter enters 48 units in zone A, the second enters 120 in zone B, and the first adds another 12 from a different row of zone A. The total is 180. If the books show 185, the difference is 5 units, and you already know where to look because every entry names its zone.

Preventing double counting

The most common problem is double counting: two workers counting the same pallet and the total coming out twice as large. Three simple rules prevent this:

1. Divide the warehouse into zones and give each zone to one person.
2. Mark what has been counted: stick coloured tape or a sticker on the rack or pallet.
3. Nobody leaves their zone to "help" in another. If help is needed, the person in charge reallocates the zones.

Control while working together

When there are dozens of data streams instead of one, the count needs watching. Every hour the supervisor asks two questions: how many positions are done and which zone is behind. If one zone is clearly slower than the rest, the reason is usually plain: goods are stacked in a mess, codes will not read, or the worker is new. The zone can then be split in two and a helper sent in.

A separate Telegram group is handy for this: questions, notes such as "this item is not on the list" and problems all land in one place.

Common mistakes when merging

• Counters use different versions of the list. A worker who counted from yesterday's file will not match the others.
• The phone clock is set wrongly, so the order of entries gets muddled.
• One person logs in from two phones and entries are duplicated.
• Goods movement in the warehouse was not stopped during the count.

Most of these mistakes are prevented by a five-minute check before the start: the person in charge confirms that everyone has the same copy of the list, the phone clocks are right and each person knows their zone.

Conclusion

Having several people count at once speeds the work up several times over, but it demands order: clear zones, marks on what is counted, a single list and hourly checks. Only then do the results add up to one correct table. If you cannot assemble such a team yourself for a large warehouse, order a count from StockCheck: the crew arrives with scanners, works zone by zone and hands over the result in one report.
