Reserve $600K for a Dallas TX hub to activate within 12 months if volume exceeds 12K orders/day or next-day SLA drops below 95%. Use ShipHero or Deposco as multi-node OMS/WMS. Stock top 200 SKUs at both locations (~80% of volume). Louisville's Worldport co-location makes the Central/Mountain air gap affordable at ~$38K/month for the ~15% of orders needing air. Total operating cost ~$158K/month. Critical failure mode: UPS Worldport dependency — a UPS disruption kills air coverage for ~30% of the country. Mitigation: pre-negotiate FedEx Express backup rates at 5-7% cost premium. Second failure mode: inventory split causes 10-15% cross-hub transfers if demand forecasting is poor, breaking next-day SLA.
