Prioritize WMS features (real-time inventory, API connectivity), pick/pack accuracy, SLA for order cycle times, reverse logistics processes, and cold-chain controls if needed. Also evaluate reporting, staffed support hours, integration with marketplace/carrier APIs, and historical KPI performance for on-time and error rates.

Proximity to suppliers and routes to Bangkok or cross-border points reduces inbound transit and drayage costs. Air cargo options shorten lead times for high-value SKUs while road connectivity supports day-range domestic deliveries. Factor in regional carrier rates, fuel surcharges, and frequency of departures when modeling landed cost versus delivery speed.

Assess certified cold-chain zones, separate loading bays, monitored HVAC and refrigeration with alarmed telemetry, validated temperature logs, redundant power and backup generators, and documented handling SOPs. Confirm capacity planning for seasonal peaks and contingency protocols for spoilage mitigation.

Negotiate clear SLAs for order accuracy, cut-off times, on-time dispatch, inventory reconciliation cadence, and penalties for SLA breaches. Include volume-based pricing brackets, minimum term and exit clauses, audit rights, KPIs with reporting frequency, and clauses for peak-season scalability and dispute resolution.

Request a carrier roster, sample transit times, proof of customs brokerage partners and documentation processes for cross-border shipments, references for similar cross-border projects, and test shipments. Review operational run-books for customs clearance, bonded storage options, and evidence of successful ASEAN routings.
