On the books but not on the shelf: finding the gap in six steps

Suppose you count 15 packs of milk powder on the shelf, but your records say 18. Three packs are missing. The first thought is familiar to everyone: somebody took them. In fact most gaps come not from theft but from paperwork and habits, and they can be traced in order. The main rule is simple: check from the simple to the complex, and question the record, not the person.

First, measure the gap exactly

Before you search, write the gap down: which item, how many pieces short or over, and how much in so'm. An illustrative example: three packs of milk powder at 62,000 so'm each, 186,000 so'm in all. Separate a shortage from a surplus, because extra stock is also a sign of error: a delivery was not recorded or a sale was entered twice. Look at one more thing: is the gap in one item or in dozens? A gap in one item usually has one cause, while a gap across many items points to a systematic error.

A six-step search

1. Recount. Let someone else do it, in a different order. Look beyond the shop floor: the storeroom, the space under the counter, the box of returns and the display window.
2. Look nearby. The item may have ended up on another shelf, next to a similar one, or wherever a customer left it.
3. Check the receiving documents. Have the latest deliveries been entered? Has one delivery been entered twice?
4. Check the sales. A gap comes from a similar item sold under the wrong code, an unrecorded cash sale, or goods sold on credit but not issued out.
5. Check the units. If a box is mixed up with a piece, or a kilogram with a gram, the gap grows tenfold in an instant.
6. Remember the small movements. Goods opened for tasting, samples, items taken by staff or the owner, and broken or expired goods are often not written off.

After each step see whether the gap has shrunk. Often everything becomes clear by the second or third step.

An illustrative example: on the recount, two more packs turn up in a box in the storeroom, because the storeroom had not been counted before. The gap falls to one pack. Then it emerges that this pack went to a customer yesterday and the sale was never recorded. The "mysterious" three-pack shortage split into two ordinary causes.

Which gaps are worth chasing

You do not have to spend hours on every gap. In weighed or very small items a difference of a piece or two is natural. So agree in advance with the team: what size of gap calls for a search? For example, one above a set amount, or one that repeats several months in a row. Set the threshold lower for expensive goods and higher for cheap, small ones. Write the thresholds down and review them once every six months. Then your time goes on the gaps that matter, not on trifles.

How to talk to people

When you find a gap, begin with a question, not an accusation: "What happened to this item last time?" or "When was that delivery booked in?". Then the employee does not defend himself but remembers and helps. Blame pushes people to hide things: next time there is a mistake he will keep quiet. Keep a short note of who did what and when, because in disputes exact data gives exact answers.

Correcting and learning

Once you find the cause, correct the records, but write the reason next to the correction: "receipt not entered", "sale under another code", "broken item not written off". If part of the gap remains unexplained after every search, record it separately as an "unexplained shortage"; do not hide it or fold it into another item's balance. An entry with a date and an amount is valuable for comparison next month.

After a month, look at the list of causes. If the most frequent one is, say, unit mix-ups, you fix exactly that spot, and at the next count the gaps will shrink by themselves.

Conclusion

A gap is a reason to worry, but not a reason to blame. Measure it exactly, check it in six steps, talk to people calmly and write down the causes, and a shortage turns from a mystery into information you can learn from. If gaps keep growing and you cannot find the cause yourself, the AniqHisob team can run a stock count, help analyse the differences and restore order in your records.
