Focus on measurable SLAs (pick/pack accuracy, order cycle time), WMS compatibility and integration APIs, surge capacity, and returns handling. Also evaluate carrier relationships and transit times to key customer zones. Consider visiting facilities to verify racking, staging, and automation readiness.

Compare base storage and throughput fees plus accessorials, inbound cross-dock costs, and negotiated carrier rates. Use historical order profiles to model weekly and peak scenarios. Consider multiple carrier options for LTL, parcel, and dedicated trucking to optimize service vs cost.

Key elements include high bay racking and mezzanines for density, dock door count and staging yards for throughput, automation readiness (conveyors, pick-to-light), and a robust WMS supporting batch, split-case, and buy-online-pickup-in-store flows. Reliable network connectivity and support services (kitting, labeling) are essential.

Verify certificate of insurance levels, inventory valuation coverage, and liability clauses. Confirm physical security (CCTV, access controls), fire suppression systems, and regulatory compliance relevant to your products (hazmat, food grade). Request audit reports and client references for validation.

Location matters: proximity to major highways, distribution hubs, and primary carrier terminals reduces last-mile cost and transit variability. Map your customer density and supplier nodes, then prioritize warehouses that cut lane miles to high-volume endpoints to improve delivery speed and lower freight spend.
