Prioritize WMS functionality and integration, inventory accuracy, SLA performance, throughput capacity, and returns handling. Also assess bonded storage, temperature-controlled zones, carrier networks, peak labor plans, and reporting/KPI dashboards to ensure alignment with your service and cost targets.

Transit times determine lead times and inventory levels. Evaluate local trucking lane density, frequency of feeder port sailings, carrier reliability, and cross-dock options. Shorter, predictable transit windows reduce safety stock and lower total landed cost to customer markets.

Expect a combination of storage-per-pallet or per-cubic-meter fees, inbound/outbound handling charges, pick & pack and kitting fees, minimum monthly charges, fuel and transport surcharges, and charges for value-added services like returns processing or temperature control.

Customs and bonded options reduce dwell and can defer duties, improving cash flow. Confirm the 3PL's experience with export documentation, transit declarations, and cross-border trucking permits. Where helpful, require explicit SOPs for inspections, quarantine, and tariff classification to avoid delays.
