Prioritize proven inventory accuracy (cycle counts, RFID/scan rates), carrier integrations for local last‑mile delivery, scalable storage (racking, mezzanine), SLA commitments for order-to-ship times, and operational transparency via WMS dashboards and KPIs.

Mountainous terrain and monsoon season can extend transit windows; select 3PLs with contingency routing, regional carrier partnerships, and flexible cutoffs to maintain predictable lead times during weather-related disruptions.

Look for secure racking and pallet capacity, pick-and-pack zones, value‑add service areas (kitting/labeling), temperature-controlled storage if needed, and clear segregation for returns processing to support B2B and eCommerce workflows.

Common models include storage per pallet/bin, pick-and-pack per order/line, and inbound handling fees. Compare total landed cost by modeling expected SKU velocity, average order lines, inbound volume, and peak season surcharges.

Evaluate customs procedures for cross-border shipments, local licensing and tax implications, documentation for inbound goods, and the 3PL’s experience handling compliance to minimize clearance delays and fines.
