Key Concepts
Four warehouse KPIs matter most: order accuracy rate (percentage of orders picked and shipped with zero errors), average pick time per order (time from order allocation to picking completion), dock-to-stock time (how long inventory takes to become available for picking after arrival), and inventory accuracy (how often system-recorded stock matches physical stock). Together these reveal both speed and quality of warehouse operations, rather than either alone.

Best Practices
Track order accuracy rate as your primary quality metric — it directly reflects customer experience and return/refund cost, more than any single process metric. Monitor pick time trends over time rather than as a single snapshot, since a gradual slowdown often signals a process or layout problem worth investigating before it becomes severe. Set a target dock-to-stock time and measure against it, since delayed put-away directly delays order fulfillment capability for that stock.

Implementation
Start tracking these four metrics this week if you aren't already — most sellers have the underlying data (order records, timestamps) but have never assembled it into these specific KPIs. Review trends monthly at minimum, weekly if order volume is high enough that issues could compound quickly between reviews.
Pro Tip
Order accuracy rate is the single metric most correlated with return rate and customer complaints — if you can only track one warehouse KPI consistently, start there.
Key Takeaways
- Track order accuracy rate, pick time, dock-to-stock time, and inventory accuracy
- Order accuracy rate is the metric most directly tied to customer experience and returns
- Monitor pick time trends over time, not as a one-time snapshot
- Set explicit targets for dock-to-stock time to avoid delayed fulfillment capability
- Most sellers have the underlying data already — it just needs to be assembled into these KPIs
