Assess national highway access, regional rail links, and proximity to airports for time-sensitive shipments. Prioritize 3PLs with established carrier contracts, consolidated LTL routes, and intermodal capability to optimize lead times and cost per pallet while preserving last-mile reach into northern provinces.

Compare hourly labor rates, workforce availability, and warehouse rent against expected pick-and-pack intensity. Factor in automation options, scalability of racked space, and SLA guarantees for accuracy and cut-off times; lower rent can offset investment in tech that improves throughput and reduces order costs.

Prioritize road carriers with national coverage, forwarders offering consolidation to Laem Chabang and Bangkok ports, and 3PLs that support rail or airport uplift for time-critical lanes. Reliable documentation and customs partners are essential for consistent export/import cycles.

Require WMS connectivity (API/EDI), real-time inventory visibility, electronic order confirmations, and returns workflows. Set KPIs for order accuracy, on-time fulfillment, and inventory reconciliation cadence. Include a phased onboarding plan with EDI tests, inventory audits, and SLA review periods.
