In many businesses the sentence spoken after a stock count is almost standard: “The record says 12, the shelf has 9.” Then comes the second standard sentence: “How can that be, we write down every movement.”
Both sentences are sincere. The gap builds up from small disconnects between the record and the day’s actual movements, which is exactly why its source is hard to find.
The gap comes from small moments, not one mistake
Looking into an inventory gap usually starts with a hunt for the big mistake: a delivery note entered incorrectly, a return nobody logged. Sometimes it turns up. But in what we have observed, the gap is more often the sum of a few small moments than a single error:
- A box handed over in a hurry with the customer at the door, with an “I’ll deduct it later”
- An item that went out as a sample and never entered any record
- A carton that came back, went onto the shelf, and never made it into the system
- A unit set aside as damaged that fell between two inventory counts
What these moments have in common is that they all happen when the work is genuinely busy. The record breaks off exactly where it cannot keep up with the natural flow of the work.
“I’ll enter it tonight” is the most expensive sentence
The scene at receiving is always the same: the vehicle is at the door, the phone is ringing, and the delivery note gets left on the desk with an “I’ll enter it tonight.” Something else comes up in the evening. The next day, whoever logs it no longer remembers where the goods were put; they might be off that day, and the note waits on the desk for a week.
The problem here is not a lack of discipline. The problem is that recording has been separated from the place and the moment the work happens. When the record lives on a desk and the work lives on a shelf, small gaps accumulate in between.
Why does the gap always surface at the worst time?
The most wearing thing about an inventory gap is its timing. If it surfaced on count day it would be a manageable accounting matter. In practice it mostly surfaces the moment someone tells a customer “we have it”: the order has been taken, the record shows 12, the shelf has 9. From that point on the options are all bad, whether that means delaying delivery, sourcing in a hurry at a higher cost, or going back to the customer to say it is unavailable.
So an inventory gap is really not a warehouse problem, it is a commitment problem. When the record cannot be trusted, a business cannot make confident commitments to its customers.
How far do spreadsheets take you?
Many businesses run inventory tracking on spreadsheets; the tool is widespread, familiar to teams, and flexible. As stock movements, user permissions, reservations, and transaction history grow, keeping the sheet current and consistent gets harder. At that stage what is needed is a system that manages the workflow rather than a sheet that only holds records.
At TechPerLab this is exactly the core we aim at with Sevkora, our live inventory and operations product: making a stock movement something you can record on your feet the moment it happens, rather than something you remember afterwards. Sevkora focuses on recording the movement as it happens and on keeping the number on the shelf and the number in the record consistent with each other.
