Prioritize on‑time delivery rates, order cycle time, inventory accuracy, and chargeback/penalty history. Confirm WMS/API compatibility, pick‑pack throughput, slotting practices, and the 3PL's ability to scale for peak season volumes. Request KPI reports and references for comparable clients.

Closer access to Laem Chabang and Bangkok air cargo reduces inbound transit time and inland haul costs, improving lead times for imports and exports. Warehouses in Hua Hin trade slightly longer ocean transit than Chonburi but benefit from lower facility costs and faster last‑mile delivery to central and southern regions.

Confirm secure racked storage, temperature control if needed, cross‑dock capacity, returns processing flows, staging for outbound carriers, and real‑time WMS features (lot/serial tracking, batch control). Check physical security, insurance, and compliance with customer product requirements.

Expect slightly longer transit to major seaports compared with Chonburi but lower facility and labor rates. Lead times to southern and central Thai markets can improve, and total landed cost may decrease for regional distribution. Model cost‑to‑serve by SKU and channel to quantify trade‑offs.

Request a systems architecture overview, API documentation, and a timeline for integrations. Run a connectivity test, review EDI/REST capabilities, sample pick‑pack flows, and examine reporting dashboards. Include integration SLAs and rollback procedures in the contract.
