Where you store your inventory has as much impact on delivery speed and shipping costs as how you fulfill orders. With consumers now expecting two-day delivery as the baseline standard, the geographic placement of your fulfillment centers is arguably the most strategic logistics decision you'll make.
The Single-Coast Tradeoff
Let's start with the numbers. If you ship from a single warehouse:
West Coast (Los Angeles / Inland Empire)
- 1-day ground: CA, NV, AZ, OR, WA, UT (~20% of US population)
- 2-day ground: CO, ID, NM, TX (~8%)
- 3+ day ground: Midwest, Southeast, Northeast (~72%)
- Advantage: Proximity to LA/Long Beach ports — lower drayage costs for Asia-imported goods
East Coast (New Jersey / Pennsylvania)
- 1-day ground: NY, NJ, PA, MD, DC, VA, MA, CT, RI (~25% of US population)
- 2-day ground: OH, NC, SC, GA, IL, MI (~20%)
- 3+ day ground: West Coast, Mountain states (~55%)
- Advantage: Dense population coverage — more people within 1-2 day zones
The Multi-Hub Advantage
Adding a second warehouse on the opposite coast instantly transforms your delivery map:
- 2-warehouse strategy (East + West): 2-day ground coverage jumps to ~85% of US population
- 3-warehouse (East + Central + West): 2-day ground coverage hits ~92%
- 5-warehouse (full network): 2-day ground coverage reaches 96%+, and 1-day becomes realistic for 40%+
The Real Savings: Ground vs. Air
The math is compelling. A 5-lb package shipped via ground averages $8-12. The same package via 2-day air: $18-25. For a brand shipping 5,000 orders/month, moving even 500 orders from air to ground through better warehouse placement saves $5,000-8,500 per month — or $60,000-100,000 annually.
What to Consider When Choosing
- Where are your customers? Run a zip code density analysis. A California-heavy customer base favors a West Coast anchor — but you still need an East Coast node to serve the Northeast.
- What's your SKU count? Splitting 50 SKUs across 2 warehouses is manageable. Splitting 500 SKUs across 5 warehouses requires sophisticated inventory allocation software.
- What's your growth trajectory? If you're growing 50%+ YoY, a multi-hub strategy today prevents painful migration later.
The Verdict
If you're doing under $2M in revenue, start with one warehouse closest to your customer density center. At $2-5M, add a second hub on the opposite coast. Above $5M, a 3-5 hub network with a single 3PL provider managing inventory allocation across nodes is where the real competitive advantage lives — and where shipping costs drop meaningfully while delivery speeds improve.
