One central warehouse vs three regional hubs for next-day delivery across the continental US? Current volume 8K orders/day, 40% West Coast.

Council notes

Evidence boundary

Observed from your filing

• One central warehouse vs three regional hubs for next-day delivery across the continental US? Current volume 8K orders/day, 40% West Coast.

Assumptions used for analysis

• Next-day delivery across continental US is a competitive requirement, not optional
• 40% West Coast order concentration is stable and not seasonal/trending
• UPS Worldport co-location actually yields $8-9/package next-day air rates at 1,200+ package/day volume
• Operating budget of ~$150-160K/month is sustainable and approved
• Top 200 SKUs represent ~80% of order volume, making dual-hub stocking feasible without massive inventory investment
• team size synthetic default (not observed): standard team (5-10 engineers) [synthetic] (not_addressed)
• existing stack synthetic default (not observed): greenfield assumed [synthetic] (not_addressed)

Inferred candidate specifics

These details were introduced by the Council during analysis. They were not supplied in your filing.

• Deploy a 2+1 hub architecture: Ontario, CA (~3,200 orders/day, serving 40% West Coast) and Louisville, KY (~4,800 orders/day, leveraging UPS Worldport for structural next-day air discounts at $8-9/package vs $14-16 elsewhere). 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. The 2+1 structure preserves capital optionality — you don't commit to a third hub's buildout until volume or SLA data justify it, but you have the activation plan ready.
• Negotiate a 3-year lease with 2-year option for a 25K-30K sq ft facility in Ontario, CA (Inland Empire submarket) and simultaneously request a UPS Worldport co-location rate card for Louisville, KY to validate the $8-9/package next-day air pricing before committing to the Louisville buildout.
• b003 (0.82) narrowly beat b007 (0.78) despite b007's lower monthly cost and better ground coverage. b003 won because: (1) staged 2+1 deployment reduces execution risk at current 8K orders/day volume — launching 3 facilities simultaneously is operationally ambitious for a company that currently has zero distributed fulfillment; (2) Louisville's UPS Worldport co-location is a named, specific structural advantage that provides an affordable air bridge while the network scales; (3) the deferred Dallas activation preserves $600K capital optionality with defined triggers. b007 is the strongest rejected alternative and should be revisited if volume accelerates past 12K orders/day or if capital is confirmed above $2M.
• b001: Hybrid model with Kansas City central warehouse + two regional fulfillment centers, $1.2M central + $400K each regional, $40K/month per location
• Less specific on carrier strategy and location logic. Kansas City as a central hub doesn't leverage any carrier co-location advantage. No explanation of how 98% next-day is achieved from Kansas City — ground radius from KC doesn't reach West Coast or East Coast in 1 day. The 35% failure mode on central disruption is worse than b003's distributed risk profile. Cost estimates lack the shipping-cost granularity that b003 provides.
• b007: 3 symmetric hubs from day one — Ontario CA, Dallas TX, Charlotte NC at $135K/month, 96% next-day SLA
• Strong competitor with better monthly cost ($135K vs $158K) and better ground coverage (92% vs ~70%). However, $1.8M buildout exceeds likely capital constraints, 3-way inventory split increases SKU stockout risk by ~20%, and launching 3 facilities simultaneously at 8K orders/day is operationally risky — b003's staged approach reduces execution risk while preserving the option to add Dallas. b007's 3PL mitigation for Dallas is pragmatic but adds complexity at launch.
• b005: Single central warehouse optimized for 2-day ground, reallocate hub budgets to inventory velocity tech

Unknowns blocking a firmer verdict

• b007's 3-hub model may actually be superior at scale — its $135K/month operating cost and 92% ground coverage beat b003, but the execution risk of launching 3 facilities simultaneously at 8K orders/day was the deciding factor. If capital budget is confirmed at $2M+ and ops team is experienced, b007 deserves re-evaluation.
• The $8-9/package UPS Worldport discount is asserted but not sourced to a specific rate card or contract — actual negotiated rates may vary significantly
• No branch validated the 40% West Coast concentration assumption or tested whether it's stable or trending
• Whether next-day delivery is actually competitively necessary (b005's challenge) was never resolved — if 2-day is sufficient for 70%+ of customers, the entire hub architecture is over-engineered
• Monthly operating cost of ~$158K against a $150K constraint is a real risk — the recommendation requires successful lease and carrier negotiations to be viable
