Evaluate throughput capacity, slotting and racking systems, same-day or next-day pick capability, WMS/TMS integration, and returns handling. Also assess port access, bonded warehouse options, reverse logistics processes, and the 3PL’s experience with eCommerce peak volumes and carrier partnerships.

Port proximity reduces drayage and total transit time for Pacific routes, while reliable highway links to the Central Valley shorten inland transit and handling. This combination lowers landed cost by cutting transport fees and dwell time, and improves predictability for cross-border and regional shipments.

Require integrated inventory visibility, pick-and-pack customization, kitting, labeling, quality inspection, bonded storage, and customs brokerage. Also prioritize 3PLs offering scalable labor, seasonal floor capacity, and advanced reporting to align with demand forecasting and vendor compliance.

Track order accuracy, on-time shipment rate, inventory accuracy, dock-to-stock cycle time, cost per pick/pack/ship, carrier OTIF performance, and claims rate. Monitor service-level adherence in contracts and review cost drivers such as storage density, handling fees, and seasonal labor surcharges.
