Prioritize transit time to key customer clusters, carrier integrations (air, road, short-sea), inventory slotting and storage types (ambient/cold), peak-season scalability, and transparent cost-to-serve models. Request SLA metrics, onboarding timelines, and references from similar verticals to validate capability.

Analyze rent per pallet position, handling throughput, inbound/outbound activity charges, and value-added services. Compare density-based pricing vs. transactional billing, seek volume tiers, and require minimum performance KPIs. Use a short pilot to validate projected costs before long-term commitments.

Confirm feeder port schedules, roll-on/roll-off service options, trucking lane frequency to southern Thailand and border crossings, and air freight capacity at Krabi International Airport. Check 3PLs' customs brokerage partners and documentation processes for export/import efficiency.

Insist on segmented inventory control, batch/lot traceability, pick-and-pack flexibility for marketplace SKUs, integrated returns processing, and reporting APIs for real-time inventory and order status. Evaluate reverse-logistics workflows and refurbishment or repackaging options for RETURNS handling.
