Prioritize capacity and layout (racking density, SKU mix), dock and trailer capacity, WMS integration and real-time inventory visibility, temperature-control options, and demonstrated SLA compliance for picking, packing and shipping. Also evaluate labor stability and peak-season scalability.

Closer proximity reduces inbound/outbound drayage, shortens transit windows and lowers fuel and handling charges. Multimodal links enable consolidation and more frequent departures, which can materially cut inventory days and decrease safety stock requirements, improving cash-to-cash cycles.

Key capabilities are WMS with lot/serial tracking, zone and wave picking strategies, automation for high-velocity SKUs, real-time scanning and returns processing infrastructure. Reliable QA processes, accurate cycle counts and integrated shipping-label automation reduce order errors and shorten cycle times.

Require clear SLAs for order accuracy, on-time shipment, and dock appointment compliance; daily inventory reconciliation, event-driven notifications, and API or EDI connectivity; defined contingency plans for labor disruptions and seasonal demand spikes, plus audit rights and performance-based penalties.

Compare landed costs including storage, pick-and-pack labor, inbound/outbound handling, transportation, and returns processing; model scenario-based volumes and peak surges; include costs for safety stock, service failure rates, and integration effort. Factor in qualitative impacts like carrier relationships and local market knowledge.
