Evaluate transit times to your customer base, inbound consolidation options, pick-and-pack productivity, SLAs for order cycle time, and the provider's carrier relationships. Also assess WMS/API integration, inventory visibility, scalability for peaks, and their experience with returns and omnichannel routing.

Zaragoza's highway access, rail terminals and airport enable mode-flexible routing—road for short hauls, rail or intermodal for cost-effective long hauls, and air for time-sensitive freight. This reduces reliance on a single lane, improves schedule options and can lower per-unit freight by enabling consolidation and multi-stop planning.

Require a modern WMS with real-time inventory, API/EDI connectivity to your ERP/OMS, configurable picking strategies, returns processing, kitting/assembly, scalable racking and temperature zones if needed. Also set clear KPIs for accuracy, lead time and on-time shipping rates.

Compare total landed cost, not just rent: include last-mile transit times, inbound freight lanes, inventory carrying costs from safety stock needs, service-level penalties, and fulfilment labor rates. Run network-scenario modeling (cost per order, delivery SLA, days-of-inventory) to quantify trade-offs.
