Prioritize SLA tiers (cut-off times, pick accuracy), WMS/API integration, inventory visibility, end-to-end transit times, carrier connectivity, labor flexibility, and real estate scalability. Compare fee structures (storage, handling, pick/pack, returns) and benchmark sample SLAs against peak-volume scenarios.

Seville offers short domestic transit times to southern and central Spain and competitive road links to Portugal. Export advantages include proximity to Andalusian ports for container exports and feasible road/short-sea links to North Africa; expect longer transit to northern Europe but reliable multimodal options for scheduled freight lanes.

Key cost drivers are warehouse rent and density, labor availability and overtime, throughput-related handling charges, last-mile parcel rates, inbound container/drayage costs, seasonality impacts, and fees for value-added services like kitting or returns processing.

Require real-time inventory visibility (WMS with APIs/EDI), event-level tracking, agreed SLA metrics (OTIF, pick accuracy, return processing times), scalable capacity plans, contingency for peaks, and standardized reporting to monitor performance and cost-to-serve.
