Stocktaking is a controlled inventory study to compare physical products in the warehouse with system records and verify the reason for the difference. Correct counting is not just counting the boxes and changing the amount on the screen. The real source of the count difference cannot be found without checking the location, product, variant, unit of measurement, lot, series and open transactions together.
The Purpose of Stock Counting Is Not Just to Equalize the Balance
Verifies the actual quantity
It physically shows which warehouse, shelf and stock status the product is located in.
Finds the faulty process
Makes recording issues visible, such as missing documents, incorrect shelves, unit conversions or transaction timing.
Prevents recurrence
If the transaction causing the difference is corrected, subsequent order, production and shipping decisions are carried out with reliable stock.
What should be prepared before inventory counting?
Preparation that begins on the counting day is preparation that is delayed. Leaving unlabeled products, open documents and mixed shelves to the counting team increases the time; It makes it unclear whether the difference found is physical or recording-related.
Is the census area clear?
Warehouse, zone, aisle, shelf and bin addresses must be clearly separated in the counting list.
Have open documents been checked?
Entry, exit, transfer, return and production transactions that have not yet been completed affect the balance at the time of counting.
Are the products separated?
Mixed product, unlabeled boxes, damaged material, and quality outstanding stock should be identified in separate locations before counting.
Is the unit of measure clear?
Conversions of pieces, boxes, parcels, kilograms, meters and packages should not be left to the counting team.
Are tasks divided?
The responsibilities of the people who count, record, make the second count and confirm the difference should be determined in advance.
Has the movement rule been determined?
During counting, movements must be stopped or separated in a controlled manner by region, time and document number.
How to Conduct an Inventory Count?
Prepare
Define the scope of the warehouse, region, shelf, and product to be counted. Check open goods receipt, shipment, transfer, production consumption, and return documents.
count
Let the counting team verify the shelf address, product code, variant, unit of measurement, and lot or serial number, if applicable, from the physical product.
verify
Recount the position that differs with another employee. Instead of writing the same number again based on the first result, perform an independent second count.
Search for the difference
Examine side shelves, wrong units, open documents, missing consumables, returns, quality blocks and timing differences with transaction records.
Close
After the real reason and the underlying document are determined, make corrections with the approval of the authorized person; Record the owner and action to prevent recurrence.
Should the Census Team See the System Amount?
In blind counting, the employee enters the physical result without seeing the amount the system expects. This reduces the tendency to verify the number on the screen. Shelf address, product code and dimensions to be counted can be shown; The expected amount is kept secret until the first count is completed.
If a difference occurs, the system quantity, the first count and the independent second count are evaluated together by the authorized person. Blind counting alone is not enough; motion control and second verification are still required.
Why Does Stock Count Difference Occur?
Wrong shelf or warehouse
The product physically exists; however, it has been left at another address or its transfer has not been entered into the system.
Open or late document
Goods acceptance, shipment, production consumption, return or transfer are recorded after the physical movement.
Product and variant confusion
Similar product code, color, size, measurement or quality class is counted in the wrong stock card.
Unit of measurement error
A box is recorded as a piece, a kilogram of material is recorded as a package, or the conversion coefficient is recorded incorrectly.
Lot and series matching error
Even if the total quantity is correct, the item appears in the wrong lot or under a different serial number.
Damage, wastage or loss
Unusable stock was not allocated, production loss was not reported, or the reason for the physical loss was not recorded.
How were the 7 gaps on the A-03-02 Shelf Closed?
While the system showed 128 units on the same shelf, blind counting and an independent second count yielded 121 units. The balance was not directly reduced to 121; Product movement and surrounding locations were investigated.
Registered quantity on shelf A-03-02.
Another employee confirmed the same physical result.
5 units were moved to the quality area, 2 units were consumed in production.
When quality transfer and production expenses were recorded, the shelf balance became 121.
Lesson: Closing the entire difference as a "count deficiency" would leave the 5 products in the quality area and the missing consumption in production invisible.
Annual Census or Cyclic Census?
Comprehensive verification on specific date
All scope in the warehouse is counted on a given closing date. Shows the whole picture for fiscal period or management verification; However, it can be difficult to find out which transaction caused the difference months ago.
Regular checks spread throughout the year
Selected products or locations are counted at the specified frequency. Valuable, fast-moving, or items that have historically shown large differences can be monitored more closely and errors can be found earlier.
The two methods do not have to be alternatives to each other. The business can control risky products and locations throughout the year with cyclic counting while maintaining periodic complete counting. For product value and movement density when determining which products will be counted more frequently From the ABC analysis guide can be used; Counting frequency should be determined not only by ABC class, but also by difference history and operation risk.
What Information Should Be Included in an Inventory Count Record?
Location
Warehouse, region, shelf and bin address.
Product ID
Stock code, variant, unit of measurement, lot or series.
Census information
Person counting, date, time and device used.
Result
First count, second count and verified physical quantity.
Difference explanation
Why the code, description and related movement document.
Closing
Correction document, approver, and preventive action.
If the counting result is kept only as the total amount on the product card, incorrect shelf, blocked stock, lot and serial differences will not be visible. Other reasons for products that appear to be in the warehouse but cannot be found in the warehouse stock difference guide; Effect of recording errors on product cost in the article on uncontrolled stock and cost and review it.
Common Mistakes in Stock Counting
Showing the system quantity to the counting team
An employee who sees the expected quantity may be inclined to verify the number on the screen rather than search for a missing box.
Making uncontrolled movements while counting
If the same item is moved before or after the count, it may be counted twice or not at all.
Correcting stock without investigating the difference
The screen balance is corrected; but the difference occurs again because the open document, wrong shelf, or faulty process remains in place.
Just look at the total amount
While the total appears correct, the warehouse, shelf, variant, lot, series or stock status may be incorrect.
Repeat the second count with the same method
A check by the same person, the same list, and the same assumption may reproduce the first error.
Leaving the count to one day a year
The movement that caused the difference cannot be determined until months later; The warehouse operates with unreliable balance for a long time.
Frequently Asked Questions
Should the warehouse be completely closed during counting?
The most obvious method is to stop movements at a full count. If the operation cannot be stopped, the listed regions, departure times and document numbers must be strictly separated; Movements before and after the counting moment should not be mixed.
By what date should the count difference be recorded?
The period to which the physical count and related movements belong should be taken into account. In case of closures that have accounting and tax implications, an evaluation should be made together with the company's financial advisor and the relevant legislation.
Will using barcodes eliminate the counting gap?
No. Barcode can reduce wrong product selection and manual entry; However, if the physical gesture is not read, the wrong shelf is used, or a document remains open, the difference still occurs.
How often should cyclic counting be done?
There is no single correct frequency. The period should be determined on a product or location basis based on product value, movement density, criticality, previous differences and counting cost.
Count, Examine and Close the Gap with Authority
Microsoft's warehouse management documentation cyclic count; It deals with the steps of creating a counting job, performing a physical count, and examining and resolving differences. SAP documentation also defines the circular method and periodic complete counting as separate methods, in which fast-moving items can be counted more frequently.
The accounting, tax and period closing effects of counting differences may vary depending on the business's recording system; Adjustments that result in financial consequences should be evaluated by the authorized finance team and financial advisor.
