Evaluate SLA performance (order accuracy, pick-to-ship time), WMS/TMS integration, inventory visibility, scalability for peaks, returns and reverse-logistics handling, and carrier connectivity. Include site visits to validate racking, safety, and labour productivity assumptions before committing.

Prioritize road access to main highways and border checkpoints, proximity to any available rail spurs or intermodal yards, on-site cross-dock capacity, and direct relationships with regional carriers and freight forwarders to reduce handoffs and transit variability.

Compare fixed versus variable cost components: storage (per pallet/ sqm), throughput fees (per pick/pack), value‑added services, inbound/outbound handling, and minimums. Factor in transport savings from location, potential customs/bonded fees, and technology access fees for accurate landed-cost modeling.

Look for providers offering bonded storage, experience with documentation and HS-code classification, proven customs brokerage partners, and standardized procedures for inspections and duty deferral. Ensure clear SOPs for inbound declarations and returns to minimize border delays.
