Key takeaways
- Record the expected quantity at the start of the count so later movements do not confuse the comparison.
- Treat every unexplained difference as a discrepancy that needs a reason and resolution.
- Post approved corrections through a movement transaction rather than editing the balance directly.
Choose the scope of the count
A count may cover the full warehouse, one location, a product group or a cycle-count sample. Define the scope, cut-off time, responsible person and whether stock movements must pause.
Create count lines from system records
Generate one line for each product and location in scope. Store the expected quantity, but consider hiding it from the counter when an independent blind count is required.
Capture the physical quantity
Record the counted quantity, date, counter and any note about damaged, unlabelled or misplaced stock. Validate that every required line is completed before the count is closed.
Calculate the discrepancy
A positive difference means more stock was found than the record expected. A negative difference means stock is missing from the expected location or balance.
Investigate before adjusting
- Unposted receipts or issues
- Stock in the wrong location
- Duplicate or incorrect product codes
- Picking or packing not completed in the system
- Damage or waste not recorded
- Unit-of-measure errors
- Counting error
- Timing difference during an active count
Record a resolution
Use statuses such as open, under review, approved adjustment, corrected without adjustment or closed with explanation. Record the reason, reviewer and action taken.
Post a controlled correction
When an adjustment is approved, create a stock movement linked to the count and discrepancy reference. Do not replace the current balance directly because that removes the history of why the quantity changed.
Review patterns, not only individual lines
Repeated discrepancies for the same product, location, shift or movement type may indicate a process problem. Reports should show frequency, quantity impact, value impact and unresolved age.
Avoid common count failures
- Completing an empty count session
- Closing a count with blank lines
- Allowing normal movements without a cut-off plan
- Using the current live balance instead of the captured expected balance
- Adjusting without a reason
- Deleting discrepancies after correction
Frequently asked questions
What is an inventory discrepancy?
It is the difference between the quantity recorded by the system and the physical quantity counted for a product and location.
Should the counter see the expected quantity?
That depends on the process. A blind count can reduce confirmation bias, while a visible expected quantity may be acceptable for a simpler check.
How should a count correction be posted?
Through an authorised stock-adjustment movement linked to the count and discrepancy reference.
Can stock move during a count?
It can, but the business needs a controlled cut-off or movement-recording method so the expected and physical quantities are compared at the same point in time.
Resolve the cause as well as the number
A controlled stock count captures the expected position, records the physical result, investigates the difference and posts an approved correction through the movement history. The strongest process also looks for repeated patterns so the underlying cause can be fixed.
