3PL Fulfillment KPIs: Formulas & Benchmarks

Quick Summary: The fulfillment KPIs worth tracking come down to five: picking and packing rate , labor cost per unit and per order , order accuracy rate , warehouse capacity utilization , and dock-to-stock cycle time . Between them they answer the three questions that decide a 3PL’s margin: how fast the work moves, what it costs, and whether it was right. Per the 2025 WERC DC Measures Report, best-in-class operations run 70 or more lines picked and shipped per person per hour, 99.68% order-picking accuracy, 90% or higher average capacity used, and dock-to-stock cycle time under 3.5 hours.
