Inventory Accuracy Formula
Industry benchmark: 95%+ general warehousing • 99%+ pharmaceutical / high-value
Why Inventory Accuracy Matters
Accuracy below 95% causes ghost stock, wrong reorder triggers, and poor customer service. Pakistani SMEs commonly operate at 70-85% accuracy, losing significant capital to emergency purchases and write-offs that stem directly from poor data.
Root Causes of Inaccuracy
Most inaccuracies come from unrecorded goods issues and receipts, manual data entry errors, theft, unreported damage, and unit-of-measure conversion errors. Fixing the root cause is more effective than repeated cycle counting alone.
Worked Example
A cycle count of 400 SKUs finds 356 accurately matched between system and physical stock, giving an accuracy rate of 89%. Against the 95% minimum acceptable standard, this flags a real problem worth a root cause review rather than a one-off correction.
Common Mistakes to Avoid
- Counting only fast-moving A items and assuming the rest of the catalog is equally accurate
- Correcting the system number without investigating why the discrepancy occurred in the first place
- Allowing the same staff who pick and pack to also perform the counts, removing independent verification
- Treating one low cycle count result as a full-year judgment instead of tracking a rolling trend over several counts
