Assess facility layout, dock and staging capacity, labor models (shift flexibility, productivity rates), and carrier density. Verify WMS/TMS compatibility, SLA terms for pick/pack/ship, returns processing, and available value-added services (kitting, labeling) to ensure the provider supports mixed-channel volumes and seasonal variability.

Prioritize warehouses close to major highways and port corridors to reduce inland haul times. Evaluate the regional carrier mix, frequency of freight lanes, and consolidation options. Shorter transit windows lower inventory-in-transit and can reduce shipping zone costs, directly improving delivery lead times and landed cost.

Confirm WMS and TMS integration capabilities, API or EDI connectivity, and real-time inventory visibility. Agree measurable KPIs such as order accuracy, on-time shipment rate, inventory shrinkage, and average order cycle time. Ensure reporting cadence and escalation paths are contractually defined.

Negotiate clear rate cards for storage, pick/pack, inbound handling and accessorials; include volume tiers and seasonal rate protections. Define minimum terms, capacity release clauses, and termination notice periods. Ensure options for rapid scale-up (temporary labor, additional bay space) to avoid service disruptions during peak demand.
