Prioritize inventory accuracy, pick-and-pack accuracy, OTIF (On Time In Full), average order lead time, and returns turnaround. Also evaluate WMS/OMS APIs, reporting cadence, SLA penalties, security, insurance, and seasonal capacity guarantees to avoid service disruptions.

Key factors include proximity to the main port and airport, direct feeder container services, frequent parcel carrier pickups, consolidated LTL networks, and cross-dock capacity. Access to reliable local carriers and established EU road links also reduces last-mile spend and transit variability.

Require a modern WMS with API/EDI connectivity, real-time inventory visibility, batch and lot tracking, support for kitting and multi-SKU orders, returns processing, and documented QA procedures. Automation for high-volume SKUs and defined exception workflows improves throughput and accuracy.

Total cost drivers include storage per pallet or cubic meter, receiving and handling fees, pick/pack rates, order minimums, packaging and labeling charges, fuel and carrier surcharges, customs clearance fees, and demurrage. Confirm volume thresholds, billing cadence, and chargeback policies to forecast landed cost accurately.
