Prioritize providers with scalable labor models, real‑time inventory systems (WMS), and clear SLAs for picking/packing. Evaluate landed cost per SKU including customs, cross‑dock fees, and transit premiums for mountain routes. Confirm peak‑season labor plans and returns processing for a reliable omnichannel experience.

Confirm bonded warehousing and customs clearance expertise because Andorran/nearby border operations can add documentation steps. Assess inward processing, VAT handling, and carrier selections that minimize dwell time. Ask providers for sample transit timelines to key B2B customers.

Expect slightly longer overland transit to major seaports compared with coastal hubs, offset by faster regional deliveries into adjacent markets. Look for 3PLs with scheduled trucking lanes, freight consolidation services, and partnerships with international carriers to balance cost and speed.

Seek facilities with modular racking, multi‑temperature zones, and reliable backup power. Important services include inventory segmentation, cycle counting, and SKU rationalization support. Verify capacity flexibility and contingency plans for route disruptions due to weather or mountain passes.
