Prioritize OTIF (on-time in-full), order accuracy, dock-to-stock and pick-to-ship cycle times, and return processing speed. Also assess WMS integration latency, inventory visibility, peak-season labor scalability, and SLA penalties tied to service failures.

Map customer density to facility location, evaluate proximity to national highways and major carriers, and model LTL vs full-truckload economics. Factor in last-mile partners, frequency of departures to Bangkok, and multimodal options to reduce dwell and expedite shipments.

Look for segregated pick areas, temperature-controlled zones (if applicable), cross-docking, returns processing, kitting/assembly, and barcode-driven lot/serial tracking. Confirm WMS capabilities, API connectivity for OMS/cart integrations, and on-site quality control processes.

Negotiate transparent rate cards for storage, pick/pack, and inbound/outbound handling; volume discounts; minimums; SLA guarantees with credits; chargeback rules for labor fluctuations; and provisions for seasonal scaling and tech integration costs.
