Prioritize throughput and dock capacity, WMS/API interoperability, inventory accuracy targets, SLAs for order lead times, and reverse logistics capability. Also assess carrier connections for parcel and LTL, labor availability, and space scalability to accommodate seasonality and SKU proliferation.

Proximity to major highways and intermodal links reduces linehaul miles and carrier surcharge exposure, improving landed cost. High carrier density boosts routing options and competitive rates, which translates into tighter delivery windows and more predictable last-mile performance for omnichannel orders.

Look for multi-level racking or high-bay storage, climate control where required, automated sortation or pick-to-light for high SKUs, real-time WMS with EDI/API connectivity, secure inventory zones, and tested procedures for kitting, returns, and peak-volume surge support.

Run a cost-to-serve model, request historical throughput and accuracy KPIs, conduct a pilot to validate onboarding timelines, review SLA credits and termination terms, and verify capacity commitments for peak periods. Factor in total landed cost, not just per-unit warehousing fees.
