Inventory Control: How to Prevent Shortages and Overstock
When the number in the program does not match what is on the shelf, a store owner asks the same question every month: where did the goods go? If stock is tracked badly, shortages and theft go unnoticed, while at the same time your money is frozen in surplus goods that nobody buys. In this article we look at why stock figures "drift", how to put things in order, how to run a stocktake properly and when it is time to move to warehouse software.
Why warehouse stock does not match your records
A mismatch is almost never caused by one big mistake. Usually it is the sum of small ones:
- Receipts are entered incompletely. The goods arrived, the invoice was promised to be entered "in the evening" — and forgotten.
- Returns are not documented. A return from a customer or to a supplier remains a verbal agreement.
- Mixed-up items. Two similar products are sold under one name: one shows a shortage, the other a surplus.
- Confusion with units of measure. Goods arrive in boxes and are sold by the piece, but the conversion factor in the program is wrong.
- Defects and expired goods. Spoiled goods are not written off and later look like they have "disappeared".
- Uncontrolled consumption. Staff take goods for themselves, hand out samples, and sometimes there is outright theft.
The main takeaway: a shortage is far from always theft. More often it is a lack of order in the paperwork. So start not by looking for the culprit, but by building the process. Once there is order, real theft becomes visible much faster.
Shortages and surpluses: a loss either way
A shortage is an obvious loss. A surplus is often seen as a pleasant surprise, but it is also a warning sign: somewhere goods were sold under the wrong name or a receipt was entered twice.
There is another kind of surplus — genuinely excess stock, meaning goods bought beyond actual demand. Such goods freeze working capital, take up warehouse space and can expire or go out of fashion. The goal of inventory control is not to bring stock to zero, but to make it manageable: for every item you know how much you have, how fast it sells and when it is time to reorder.
Seven rules for orderly stock
- Every movement gets a document. Receipt, sale, return, transfer between warehouses and write-off are separate document types. Nothing leaves the warehouse without a document.
- One product catalog. One item, one card: name, SKU, barcode, unit of measure. Duplicate cards split the stock in two.
- Receipts on the day of arrival. Accept goods against the invoice with a recount and enter them into the system immediately.
- Financial responsibility. Every warehouse or department has a responsible person; when that person changes, the stock is recounted and handed over.
- Write-offs with a reason. Defects, expiry and samples are separate reasons, so you can later analyze where losses come from.
- Minimum stock level. For key items, set a "below this — reorder" level.
- Regular partial counts. Instead of a rare big audit, check one product group every week.
How to run a stocktake properly
A stocktake compares actual stock with recorded stock. To get a useful result, follow a few simple conditions:
- Stop movement during the count or close the department being counted. Otherwise sales made during the count will distort the total.
- Count in pairs: one person counts, the other records or scans. The person responsible should not recount their own department alone.
- Use a scanner or a smartphone. Counting by barcode is faster than writing by hand and produces fewer errors.
- Investigate discrepancies right away. Match shortages and surpluses across similar items — this is usually how mixed-up items are uncovered.
- Document the results. Discrepancies are closed with a write-off or stock-in act that states the reason.
It is best to combine the types of stocktaking:
| Type | When it is used | Pros | Cons |
|---|---|---|---|
| Full stocktake | At the end of a period, when the responsible person changes | Complete picture | Requires stopping work |
| Cycle count | One product group every week | Work does not stop, errors show up quickly | Requires discipline |
| Separate count of expensive items | Small, expensive, fast-moving goods | The biggest risk is under control | The list must be drawn up correctly |
| Surprise check | When there are suspicions | Shows the real situation | Only as an additional tool |
When Excel and notebooks are no longer enough
A small store can keep records in a notebook or Excel at the start. But if at least two of the signs below apply, it is time to introduce warehouse software:
- many items, and products come in sizes, colors or varieties;
- several salespeople or cash registers work at the same time;
- two or more warehouses or branches;
- to find out the stock you have to call the warehouse or go and look;
- every audit ends with a noticeable discrepancy that nobody can explain.
The main problem with Excel is that it is not connected to sales. Every sale from the register has to be copied into the spreadsheet by hand — and this is where errors appear. The file exists in several copies, and it is impossible to establish who changed a number and when.
How software controls your stock
In a proper warehouse and POS system, stock changes in real time: a sale at the register immediately reduces stock, a receipt increases it. The manager gets:
- Current stock for every warehouse and branch — from a phone or computer, from anywhere.
- Movement history for each product: who posted it, when and with which document.
- Minimum stock alerts — for example, a message in Telegram.
- A list of slow-moving goods — so you can spot surpluses in time.
- A stocktaking module — counting with a scanner and automatic calculation of discrepancies.
- Roles and access rights — a salesperson cannot change stock; only the responsible person can, through a document.
The UFLEX team builds inventory and POS systems for stores, wholesale and manufacturing — not a template, but a system built around your products, units of measure and branches. If you already use accounting or other software, it can be connected through an integration so data is not entered twice.
Common mistakes when rolling it out
- Entering opening stock without a recount. Old errors move into the new system. Run a full stocktake before launch.
- Staff are not trained. The program exists, but receipts are still written in a notebook and entered "later".
- Changing everything in one day. It is safer to launch the system at one warehouse or one branch and then expand.
- Results are not checked. In the first months, do spot recounts more often to make sure the records are being kept correctly.
Frequently asked questions
How often should a stocktake be done?
It depends on the goods. Expensive and fast-moving items are best counted often, the rest in turn using the cycle method; a full audit is usually done at the end of a period and when the responsible person changes.
Does a small store need warehouse software?
If the range is small and one person works there, simple records may be enough. As the range, staff or number of locations grows, manual records start producing errors and the software pays for itself.
How much does warehouse software cost?
The exact price depends on the task: the number of branches, work with the register and scanner, integrations and the volume of reports. Describe your requirements in a request and we will estimate the project.
If you want to put your stock in order, briefly describe your process and leave a request or message us on Telegram. UFLEX is an IT team from Namangan; we work remotely with businesses across Uzbekistan, host the system on a server and support it after launch.
