Prioritize capabilities that directly affect lead time and cost: order processing speed, inventory accuracy, cold‑chain if required, pick‑and‑pack flexibility, and proven regional carrier networks. Also evaluate local handling for customs and cross‑border documentation to avoid delays.

Selecting a local 3PL can reduce domestic road miles and enable freight consolidation at origin, but performance depends on partner relationships with regional carriers and customs brokers. Expect variable transit times during rainy seasons and plan carrier redundancy and scheduled consolidation lanes.

Key cost drivers include storage density and rack utilization, pick‑and‑pack labor rates, inbound consolidation fees, cross‑border handling and duties, minimum billing increments, and inventory carrying costs. Model cost‑to‑serve by SKU, zone, and order profile.

Require SLA metrics for order cycle time, pick accuracy, inventory reconciliation frequency, damage and shrinkage rates, and dispute resolution timelines. Verify operational capacity, contingency plans for seasonal road issues, and documentation for cross‑border compliance before signing.
