Prioritize carrier access (road/rail/air), SLA for pick-pack-ship, WMS capabilities and real-time inventory sharing, cross-dock and kitting services, racking density, inbound lead-time management, and scalability for peak seasons. Evaluate pick accuracy, returns handling, and reporting cadence aligned to SKU mix and channel split.

Key cost drivers: lower land rents and labor rates in Lamphun typically reduce storage and handling OPEX; utility and estate fees vary by industrial park. Transport costs to major consumption centers can be higher per-km but offset by lower storage and labor. Assess total landed cost including first/last-mile legs and inventory carrying.

Expect shorter regional transit to northern Thailand and fast access to Chiang Mai. Transit to central hubs depends on carrier and routing; many shippers achieve reliable next-day or two-day delivery to major northern centers and competitive two-day road transit windows to Bangkok with optimized consolidation and carrier selection.

Require a modern WMS with API/EDI connectivity, real-time inventory feeds, order-routing logic, barcode scanning, and reporting dashboards. Look for support for marketplace integrations, batch and lot tracking, returns processing, and configurable SLA rules to manage multiple sales channels and distributed inventory pools.

Audit inventory accuracy, pick/pack cycle times, on-time shipment rate, dock-to-stock times, storage utilization, safety/compliance, IT uptime, and capacity for expansion. Verify dock layout, racking condition, labeling standards, staff skill levels, and sample operational reports to validate performance claims.
