5 Warehouse Mistakes That Cost You Money (and How to Fix Them)
Accounting and inventory mistakes can eat up to 15–20% of your warehouse margin. Five practical steps — from SKU standardization to cyclical inventory — to regain control and reduce losses.

Do you know which hidden enemy can consume up to 15–20% of your warehouse margin in Uzbekistan? These are accounting and inventory errors. Every shortage or mis-sorting is not just a number in a report but real money lost due to supply disruptions, frozen working capital, and decreased customer trust.
In this article — five most costly reasons for warehouse losses and simple steps to eliminate chaos and regain control.
Mistake #1. Catalog issues: duplicate SKUs, different units, similar items Symptoms: mis-sorting among similar products, repackaging errors, manual corrections. Cause: no unified product data reference: duplicate articles, different units of measure, lack of strict naming rules. What to do:
- Approve SKU rules and unique codes.
- Ban “free input” in the system — only from reference guide.
- Deduplicate and match packaging.
- Implement barcode for all storage units.
- Assign a master data owner. 💡 In our experience, tidying up the catalog reduces picking errors by 20–30%.
Mistake #2. Weak receiving: 'trusting the invoice' Symptoms: discrepancies immediately after delivery, shortages of “hot” SKUs, disputes with suppliers. Cause: no incoming control standards and supplier error KPIs. What to do:
- Introduce two-stage receiving: quantitative + qualitative.
- Organize a quarantine zone.
- Use scanning and photo documentation.
- Maintain KPI “% of supplier errors”.
- Any doubtful items — quarantine until resolved. 💡 Companies that implemented photo documentation and a quarantine zone reduced disputes with suppliers by 40%.
Mistake #3. Unaddressed storage and mixed batches Symptoms: long search time, chaotic bins, FIFO/FEFO violations. Cause: no address storage system and labeling. What to do:
- Introduce address storage by “row/section/level/bin” principle.
- “One bin — one SKU/batch”.
- Strict FIFO/FEFO compliance.
- Move “piles” and returns to separate zones. 💡 Address storage reduces search time by 30–50% and decreases expiry-related shortages.
Mistake #4. Manual input instead of scanners Symptoms: picking errors, different numbers in Excel and system. Cause: manual input of codes and quantities allowed, no validations. What to do:
- Switch to barcode/QR scanning.
- Provide TSDs or smartphones with the app.
- Block manual input at critical stages.
- Enable automatic validations. 💡 Scanning reduces human error and speeds up operations by 25–40%.
Mistake #5. 'Inventory once a year' Symptoms: stress, downtime, unclosed discrepancies. Cause: inventory not embedded into operational cycle. What to do:
- Implement cyclical inventory:
- A — weekly,
- B — monthly,
- C — quarterly.
- Use triggers for unscheduled counts.
- Conduct “blind” double counts for A-group.
- Immediately close discrepancy acts. 💡 Companies implementing cyclical approach reduced annual shortages by 15–25%.
Mini-guide: 'Inventory in 24 hours'
- T-24h: assign responsible persons, export balances, check TSDs.
- T0: stop movements, assign tasks, count by routes.
- T+24h: reconciliation, acts, adjustments, KPI updates.
