Prioritize location relative to major highways and cross-border routes, WMS features (real-time inventory, API/EDI), pick-and-pack accuracy, SLAs for order lead times, returns handling, and carrier integrations. Verify scalability for peak seasons and clear cost models for storage, picks, and value-added services.

A Navarre location shortens overland transit to northern Spain and southwestern France, enabling faster LTL and parcel transit and potential consolidation savings. Proximity to major corridors reduces drayage and dwell time, which lowers overall landed cost for cross-border lanes.

Require a robust WMS with EDI/API, ASN and PO management, lot and serial tracking, scalable bulk-handling and palletization capabilities, reliable reporting, and integration with ERP and carrier systems to support B2B cadence and compliance.

Evaluate seasonal capacity planning, temporary labor programs, overflow storage options, SLA performance during previous peaks, returns processing workflows, and the 3PL’s ability to provide same-day pick/pack windows and transparent performance dashboards.

Focus on how the provider charges for storage (floor vs. rack), receiving, handling, picks, packing materials, minimums, seasonal surcharges, and transport markups. Seek clear KPIs, penalty/bonus clauses, and a defined onboarding/trial period to validate assumptions before long-term commitment.
