Focus on inventory accuracy, order cycle time, on‑time delivery rates, and pick/pack throughput. Require WMS/WAPI integration, real‑time inventory visibility, shipment tracking, and SLA penalties. Evaluate carrier connectivity, returns handling, and peak‑season scalability to align service levels with customer expectations.

Proximity to major highways and regional rail reduces drayage and overland transit times, lowering LTL/FTL rates. Nearby airports and customs brokers accelerate export/import cycles. Assess local carrier density, frequency of service, and multimodal options to optimize routing, consolidate loads, and control landed costs.

Priority features include high‑bay racking, configurable mezzanines, scalable dock doors, and climate control where required. Value‑added services should cover kitting, custom labeling, lot tracking, returns processing, and light assembly. Verify staffing models, training, and contingency plans for peak demand.

Model fixed vs variable costs: CapEx for facilities and equipment versus 3PL monthly fees, pick/pack charges, and storage. Include labor, utilities, IT integration, and inventory carrying costs. Factor in flexibility gains, speed to market, and risk transfer for seasonal demand or geographic expansion when calculating total landed cost.
