Prioritize accurate inventory management, integrated WMS with real-time visibility, scalable picking and packing resources, cross-docking and returns processing, and value-added services like kitting. Confirm SLA metrics for order accuracy, pick lead time, and on-time dispatch to protect customer experience.

Location affects road miles to primary routes and coastal ports, influencing carrier selection and fuel/truck rates. Sites nearer trunk roads reduce transit times and carrier handoffs; more remote sites can lower rent but increase last-mile and drayage costs. Model landed cost vs. rent to find the right balance.

Validate structural capacity (racking, floor load), electrical and climate control for sensitive inventory, security and insurance, IT integration (EDI/API), and documented health & safety and contingency plans. Ask for performance data: inventory accuracy, on-time shipments, and damage rates.

Negotiate transparent fee schedules (storage tiers, pick/pack, inbound handling), minimum volume clauses, rate review periods, and clear SLAs with service credits. Include exit and transition terms, and options for seasonal labor scaling to avoid hidden cost exposure.
