Counting stock with a phone: how it works

In many warehouses a stock count still looks the same: a paper sheet, a pencil, one person counting, another writing, and then someone retyping everything into Excel. Mistakes can creep in at every step: a digit is misread, a line gets skipped, a sheet goes missing. Counting with a phone shortens that chain. The code is read by the camera, the quantity is entered on the spot and the result goes straight into one shared list.

How a single item is counted

The process is simple and repeats the same way for every product.

1. The worker points the phone camera at the item's barcode or QR code.
2. The app recognises the code and shows the product name and article number from the list. The worker checks by eye that it is the right item.
3. The quantity sitting on the rack or pallet is entered, or each unit is scanned one by one.
4. Once confirmed, the entry is saved on the phone and, if there is a connection, sent to the shared list too.

The whole cycle takes a few seconds. The two paper steps, writing down and then typing up, disappear entirely.

What to prepare beforehand

A phone alone is not enough. Preparation decides the quality of the result:

• The count list. A table from Excel or 1C with article, name, code and the booked balance. Items without a code need a row too.
• Phones: one per counter, fully charged, with a clean camera lens. Fingerprints are a common cause of slow reading.
• Zones: the warehouse is split into sections and each has a named person in charge.
• Connectivity: you know in advance where there is no internet. Basements and cold rooms need a plan for working offline.

Pay special attention to the quality of the list. If the same item appears under two names or the code column is empty, the counter has to hunt for it by hand and time is lost. Cleaning the list in advance takes an hour, yet it saves several hours on the counting day.

How it differs from paper

Say the warehouse holds 2,000 positions. On paper each position is written at least twice: when counted and when entered into the table. With a phone it is written once. Recounting is easier too: on paper you fill in a new sheet, while on a phone you simply scan the item again.

There is a second big difference. On paper, discrepancies only become known after the count is finished, when someone reconciles the tables. With a phone, comparison against the list begins during the count, so a doubtful item can be rechecked while the worker is still standing at the rack.

How the counting day runs

A successful count usually rests on a simple plan:

1. A short 15-minute briefing before work starts: who is in which zone, which code counts, how to correct a mistake.
2. In each zone, during the first minutes, the person in charge personally checks a new counter's first few items.
3. Every hour, an interim result is requested: how many positions are done and which zone is falling behind.
4. When all zones are closed, the discrepancy list is produced and doubtful items are recounted by a different person.
5. Only then is an adjustment entered against the booked balance.

The fifth step needs the most care. The biggest mistake is to correct the books the moment a difference appears: the cause stays unknown and the same gap reappears in the same place next time.

Common mistakes

• An item has two codes (on the pack and on the unit) and the worker gets confused. Agree beforehand which code is the one that counts.
• An extra zero slips in during manual entry: 120 instead of 12. If a number stands out sharply, have the worker look again.
• Goods keep moving during the count and the figures drift. Pause receiving and dispatch, or record them separately.
• Counters use different versions of the list. Check that everyone has opened the same, current file.

Conclusion

Counting with a phone depends less on the technology than on the working routine: a ready list, clear zones, charged phones and a trial run. With those four things in place there is no reason to go back to paper and retyping. If you have no time to organise it yourself, you can order a count from StockCheck: the team arrives with scanners, counts, and hands over the discrepancy list as an Excel or PDF file.
