Prioritize picking and packing methodologies (batch, zone, wave), inventory accuracy, real-time WMS integration, proximity to ports/consumer markets, and established last-mile carrier interfaces. Automation for sorting and returns processing further reduces cycle time and error rates.

Model TCO including storage, handling, inbound/outbound transport, duties, and inventory carrying costs alongside SLA-driven metrics (lead time, fill rate, OTIF). Use scenario analysis for peak demand and service failure costs to balance price with reliability.

Confirm bonded warehouse status, on-site customs brokerage or accredited partners, experience with export processing zones, and documentation accuracy. For regulated goods, validate controlled-temperature chains, traceability, and compliance with local import/export regulations.

Evaluate historical surge performance, flexible square footage options, labor pools and staffing plans, contingency carrier agreements, WMS scalability, and SLAs for peak periods. Require playbooks for ramp-up, KPIs for scale, and change-order cost transparency.
