Prioritize service mix (pick/pack, kitting, returns), warehouse footprint and layout, SLA guarantees for order cycle times, and carrier integrations. Also assess regional carrier reach, volumetric pricing tiers, inventory accuracy (WMS features), and contingency plans for mountain‑route disruptions.

Transit times vary with route and weather; overland connections provide efficient access to inland centers while port transit to Buenaventura or Cartagena requires planning for mountain gradients and longer haul legs. Consider multi‑modal routing and consolidated shipments to optimize coastbound transit and carrier cost.

Key cost drivers include rent per square meter, racking and mezzanine needs, labor rates and productivity, utility costs for climate control, and value‑added processing hours. Evaluate seasonal labor availability and staff training for SKU complexity to control pick accuracy and throughput.

Require clear temperature‑control specs, monitored HVAC and alarms, documented chain‑of‑custody, secure racking and access controls, and insurance options. For clarity, assess:

• Temperature ranges and monitoring frequency
• Backup power and contingency plans
• Segregated secure storage zones

Negotiate clear SLAs for order accuracy, lead times, on‑time fulfillment, and returns processing. Include KPIs for inventory accuracy, dock-to-delivery times, chargeback triggers, and scalable pricing brackets tied to volume to support predictable cost modeling during growth phases.
