Prioritize proximity to target customer clusters, multimodal connectivity, warehouse type (ambient vs temperature controlled), IT integration (WMS/APIs), and scalable labor. Also assess carrier partnerships for last‑mile coverage and cross‑dock capability to reduce handling and transit time.

Look for real-time inventory visibility, batch picking and zone optimization, returns processing, kitting/assembly, and temperature control if needed. Evaluate throughput capacity, slotting flexibility, and parcel manifesting support to meet peak volumes and frequent promotions.

Model landed cost by combining: origin freight to the 3PL, local handling and storage fees, outbound carrier rates, and average last‑mile cost. Include buffer for seasonal dwell, inventory carrying cost, and regional surcharge variability. Use historic transit times from the provider to quantify lead‑time risk.

Include clear SLAs and KPIs for order accuracy, on‑time shipment rate, inventory accuracy, and lead time. Consider adding:

• Order accuracy (target %)
• Inventory reconciliation cadence
• Chargeback and remediation clauses
• Business continuity and disaster recovery commitments
