Prioritize operational metrics that impact cost and speed: order processing SLA, average pick‑pack times, SKU storage density, inventory accuracy rates, and scalability for peaks. Also evaluate carrier integration, WMS capabilities, and transparent billing to avoid hidden transport and handling fees.

Closer access to major highways reduces trunk miles and fuel spend, lowers transit variability, and shortens delivery windows. That improves on‑time rates and reduces buffer inventory requirements, translating into lower working capital and better customer fulfillment metrics.

Look for facilities with high bay clearances, heavy‑duty racking, forklift and pallet jack capacity, dedicated cross‑dock bays, and flexible loading schedules. Ensure the 3PL offers EDI/API carrier integrations, appointment scheduling, and damage‑tracking procedures to protect freight integrity.

Common levers include consolidating shipments for higher cube utilization, optimizing pallet and packaging dimensions, using zone‑skipping for dense regions, negotiating multi‑carrier contracts, and leveraging seasonal labor flex rather than fixed headcount. Regular KPI reviews with the 3PL help identify further process improvements.
