Assess multimodal connectivity (road and river access), bonded or customs-cleared storage, local labor availability, and proximity to cross-border checkpoints. Also verify carrier networks for last‑mile reach, capabilities for temperature-controlled inventory, and the 3PL's experience with cross-border documentation and transit consolidation.

Prioritize WMS functionality (real-time inventory, API integrations), order routing logic, carrier rate and tracking integrations, returns management, and SLA guarantees for pick/pack accuracy and cut-off times. Request KPIs and references showing consistent lead times across peak periods.

Expect lower real estate and labor costs, which can reduce inventory carrying expenses, while transit times to major seaports or Bangkok distribution centers may increase. Calculate total landed cost including longer-haul freight, and evaluate consolidation opportunities, cross-docking, and inventory placement strategies to balance service levels and unit economics.
