Carriers bill your dimensional weight, not your actual weight — so you pay for air on every bulky box. ShippingCow is a self-operated US 3PL for 50–149 lb parcels: we pool enterprise FedEx rates across our merchant herd and zone-skip your parcels into the network at Zone ≤ 4.

You're losing thousands a year to DIM weight guessing, retail carrier rates, and zone 7–8 surcharges. We fixed all three.
Your carrier bills dimensional weight at divisor 139 — so a dense 50–149 lb product in a right-sized box still gets charged for air. We audit every DIM line on your invoice and re-engineer the packaging that causes it.
We pool volume across our entire merchant herd. You get enterprise FedEx rates without enterprise volume — plus discounted fuel surcharge you can't get retail.
Zone-skipping injection puts your parcels into the last-mile network at Zone ≤ 4 instead of Zone 7–8 — shorter distance billed, shorter distance travelled.
No sales call. No commitment. Pick one and get a number in minutes.
Enter weight and dimensions. See the billable weight your current carrier is charging you for at the published DIM divisors — the phantom pounds in plain sight.
