Packages that ship cheaper from Phoenix stay in Phoenix.
Illustrative. ONI routes eligible packages one at a time; the regions served depend on each brand's shipping profile.

ONI decides per order, by destination: if Phoenix is cheaper, it ships from Phoenix.
Modeled, not measured: Premium3PL shipments June 1–September 26, 2026 (329,460 packages; 176,205 routed), priced on actual carrier rates. Results vary by product weight, destination mix and carrier eligibility. Measured results replace these figures after ONI's first eight weeks in operation.
Process · Three steps
Your orders are picked and packed in our Phoenix-area fulfillment center, as usual.
Packages for distant regions travel by air each night to regional injection points.
They enter the carrier network near the customer, in a lower delivery zone. Packages that ship cheaper from Phoenix stay in Phoenix. ONI chooses per package, and you see the result on every invoice.
Zones · Why distance costs money
Carriers price parcels by distance zone, from 1 (local) to 8 (cross-country). The higher the zone, the higher the price and usually the longer the transit.
From Phoenix, a package to the far East Coast is typically zone 8. Entered in the Northeast, the same package starts in a low zone.
Network · One inventory, national reach
Splitting inventory across fulfillment centers shortens the distance to some customers. It also multiplies almost everything else. In our experience, for most brands shipping fewer than about 1,000 orders a day, the extra inventory, freight and management cost more than the zones save.
1.7×safety stock at three sites (1.4× at two)
Every site needs its own safety stock. Inventory planners' rule of thumb, the square-root law, puts the safety stock for three locations at roughly 1.7 times what one location needs.
Sold out here. Overstocked there.
A best-seller sells out in one warehouse while it sits in another. You ship it the long way anyway, or lose the sale.
2,000+ mifrom the Southern California ports to an eastern site
Inbound shipments split across sites, then transfers to rebalance them. For goods made overseas, an eastern site starts with a cross-country haul from the port before the first order ships.

The long tail gets thinner at each site, and so do your margins for error.

Managing inventory is hard at one location, difficult at two, and a nightmare at three or more. In our experience, a second site needs a full-time inventory and logistics planner, just to coordinate stock, suppliers and freight.
