Port proximity and modal options impact transit time, handling costs and routing flexibility. Look for providers with short dray times to terminals, direct rail/barge services, low container dwell times and proven consol/cross-dock operations—these reduce lead times and inventory carry while improving consistency across lanes.

Prioritize accurate WMS integration, real-time inventory visibility, scalable pick-and-pack capacity, returns management, kitting/assembly and temperature-controlled storage. Also assess SLAs for inventory accuracy, order cycle times, and exception handling to ensure operational alignment with customer promises.

Compare fixed versus variable components: storage tiers, per-pick/pack fees, handling rates, receiving charges, minimums and accessorials. Review bill-back practices for inventory adjustments and freight allocation. Clarify currency, VAT handling, demurrage responsibilities, and any seasonality or peak surcharges before committing.

Typical ranges depend on carrier schedules and lane density: same-day or next-day cutoffs within the Benelux, 1–3 day transit to adjacent regions in Germany and France, and 2–4 days to more distant EU markets. Service consistency depends on carrier frequency, customs handling and whether the 3PL supports cross-dock or express parcel integrations.
