Prioritize demonstrated inventory accuracy, SLA-backed order cycle times, carrier integrations, and scalable labor. Confirm system compatibility (WMS/APIs), visibility tools, and contingency plans for transit disruptions. Evaluate per-unit pricing, inbound receiving terms, and value-added services such as kitting and returns processing to match your channel mix.

Proximity to main corridors shortens transit times and reduces fuel and linehaul costs. Warehouses near consolidation points or feeder ports enable more predictable lead times. Carrier availability determines parcel pricing tiers and last-mile reliability, affecting both landed cost and final-mile SLA adherence for omnichannel delivery.

Look for racked storage with scalable square footage, dedicated receiving docks, zone-directed picking, batch processing, and workforce flexibility for seasonal peaks. Confirm cold chain or controlled-environment options if needed, plus robust IT integrations for order throttling and real-time inventory reconciliation.

Negotiate clear SLAs for order accuracy and on-time fulfillment, transparent fee schedules for storage and value-added services, defined chargeback mechanisms, and inventory custody terms. Include performance-based reviews, defined dispute resolution, and exit provisions to manage scale-up or re-shoring decisions.
