Prioritize transit connectivity, dock and racking density, slotting and SKU velocity analysis, SLA-based inventory accuracy, and carrier integrations. Also evaluate labor flexibility, peak-season scalability, IT compatibility (WMS/API), and transparent costing for storage, pick/pack, and inbound handling.

Core components include storage (per pallet or cubic meter), receiving and putaway, pick-and-pack labor, packaging materials, outbound freight management, and value-added services (kitting, returns processing). Look for clear unit rates, minimums, and volume discounts to model true landed cost.

Require a modern WMS with real-time inventory, API-based order and shipment integrations, EDI/CSV support, configurable reporting dashboards, and automated alerts for exceptions. Ask for historical KPIs (OTD, pick accuracy, receiving cycle times) and audit access for periodic inventory verification.

Onboarding typically ranges from 4 to 12 weeks depending on complexity: 1–2 weeks for systems integration and test orders, 2–4 weeks for initial receiving and slotting, and additional time for process validation and staff training. Complex assortments, temperature control, or custom packaging can extend the timeline.
