Prioritize throughput capacity, flexible labor agreements, scalable racking and staging, pick/pack efficiency, returns processing, and load-building for carriers. Verify SLA commitments for order cutoffs, same/next-day options, and contingency plans for seasonal surges to protect customer experience.

Assess proximity to interstate arteries, trailer parking and turn capabilities, cross-dock and consolidation services, and local LTL/FTL carrier density. Evaluate dock-level capacity, yard management, and appointment systems that reduce dwell time and freight detention.

Compare storage (per pallet/cubic ft), pick/pack (per order/line/item), receiving and handling charges, kitting and value-add fees, and minimums. Watch for billing frequency, dimensional pricing, inventory reconciliation charges, and transportation pass-throughs that affect total landed cost.

Require a modern WMS with EDI/API integrations, real-time inventory visibility, order routing and batching, carrier rate shopping, and custom reporting dashboards. Confirm audit trails, SLA reporting, and access to shipment tracking and exception management for compliance and analytics.
