Evaluate lead times to target postal codes, available carrier integrations (local and international), pick/pack accuracy metrics, slotting and SKU density, and whether the 3PL supports peak scaling. Also review warehouse management system (WMS) capabilities and real shipping cost models to compare landed cost and service levels.

Proximity to ports and intermodal terminals reduces drayage and modal transfer time, enabling consolidated LCL/FCL scheduling and flexible cross‑dock operations. Benefits include lower per‑unit transport cost, shorter dwell time for inbound cargo and simplified customs handling for EU trade lanes.

Key components: inbound freight, domestic last‑mile, inventory carrying cost, and handling fees. Brands should model scenario-based volumes, compare per‑unit handling and storage rates, include regional labor assumptions, and run landed‑cost simulations to quantify savings against alternative sites.

Look for a WMS with real‑time inventory sync, API carrier integrations, advanced pick/pack rules, returns management, and reporting dashboards. Consider SLA guarantees for order cutoffs, same‑day/next‑day options, and KPIs for order accuracy and return turnaround. You may request a pilot to validate performance.
