Inventory Accuracy
Inventory Accuracy is how closely the inventory quantities in the system match what is physically in the warehouse.
Why it matters for ecommerce brands
Low accuracy causes overselling, cancellations, and wasted safety stock.
Formula and calculator
Inventory accuracy = locations (or SKUs) with matching counts ÷ locations counted × 100
Common questions
- What inventory accuracy should I expect from a 3PL?
- Many 3PL contracts commit to 99% or higher inventory accuracy, measured by cycle counts. Check how the contract defines accuracy, since unit-level and location-level measures give different results.
