Prioritize carrier connectivity and transit times to key markets, facility capabilities (racking, temperature control, cross-dock), WMS/API integration, labor availability and cost, value‑added services (kitting/returns), SLA guarantees, and transparent rate structures that align with order profiles and seasonal demand.

Rates in Kamphaeng Phet often reflect lower real estate and labor costs but higher per-shipment trucking to distant dense urban centers. Negotiate minimums, storage tiers, pick-and-pack pricing, inbound handling, carrier passthroughs, and performance-based incentives tied to inventory velocity and shipment volumes.

Require a WMS with real-time inventory visibility and APIs/EDI for your OMS, carrier integrations for rate-shopping and tracking, efficient returns processing, batch/kitting capabilities, and analytics for SLA monitoring and cost-per-order reporting to optimize omnichannel flows.

Confirm the 3PL's experience with Thai customs procedures, bonded warehouse options, export documentation, and transit permits for cross-border lanes. Ensure they offer customs brokerage or partnerships, clear lead-time estimates for clearance, and compliance procedures for regulated products.
