Evaluate carrier connectivity, customs handling experience, bonded storage availability, WMS/API integrations, SLA transparency, cross-dock throughput, labor skill and shift patterns, security and power reliability, and the provider's ability to scale footprint and services as order volumes change.

Cross-border trade increases the need for customs-compliant processes, documentation accuracy, bonded or temporary storage, reliable trucking partners, and contingency plans for border delays. Providers with documented cross-border experience can reduce dwell time and improve delivery predictability.

Priority features include modular racking and staging areas, dedicated packing and returns zones, real-time WMS with API/EDI, order management compatibility, secure inventory segregation for bonded goods, and performance analytics to monitor pick/pack cycle times and fill rates.

Include transport tariffs and tolls, fuel surcharges, customs duties and clearance fees, carrier transit times and reliability, local last-mile costs, inventory carrying costs, handling fees at the 3PL, and expected border delay variability to model total landed cost and service windows.
