Prioritize multimodal connectivity (road and rail access), pick‑and‑pack throughput, warehouse racking density, IT integrations (WMS + EDI/API), returns processing capabilities, and SLA performance for peak season scaling. Also verify labor availability and real estate flexibility for seasonal SKU volume changes.

Close proximity shortens last‑mile and port drayage times, expands carrier options for full‑load and LTL services, and reduces transit variability. That improves predictability for inbound replenishment and outbound eCommerce delivery windows to Northern Europe.

Key cost drivers include land and rental rates, labor wages and productivity, handling equipment utilization, inventory density (pallet vs. bin), cross‑dock frequency, and transportation distance to end markets. Optimizing layout and SKU velocity reduces per‑unit costs.

Expect WMS-driven inventory visibility, real‑time order routing, kitting and light assembly, returns management, lot and batch tracking, temperature‑controlled handling if needed, and API/EDI integrations for order, shipping, and inventory synchronization across channels.

Confirm whether providers offer bonded warehousing, customs brokerage support, and experience with cross‑border documentation. For multi-country distribution, ensure the 3PL can manage duties, transit declarations, and expedited cross‑border carrier options to minimize clearance delays.
