Evaluate order cycle time, dock-to-stock and pick-to-ship speeds, inventory accuracy, space utilization, and cost per fulfilled order. Also confirm WMS integration, SLA penalties, and capacity scalability for peak seasons to ensure consistent service levels.

Compare available services such as bonded storage, cross-docking, multi-temperature zones, kitting, returns processing, and last-mile partnerships. Request performance data (OTD, accuracy, chargebacks) and tour operations to validate capabilities.

Assess proximity to major highways, freight carrier density, availability of intermodal links, and local transshipment nodes. Factor in fuel surcharges, dwell time, and regional transport frequency to model true landed cost.

Require real-time WMS with API/EDI connectivity, inventory visibility dashboards, ASN/EDI support, scalable pick logic (batch/wave), and returns management. Confirm data security, uptime SLAs, and integration testing timelines before onboarding.
