The Process
How It Works
Mountainy partners directly with UniUni to route qualifying shipments through their network - automatically, with zero manual effort on your end.
Order Placed
Automating order flow from Shopify into your 3PL or warehouse with no manual exports or re-entry
Automatic Rate Shop
Our system checks the destination ZIP code and compares UniUni's rates against USPS and all other carriers in real time.
Best Rate Wins
If UniUni offers the lowest cost for that metro destination, the shipment is routed through their network - saving you money automatically.
Smart Logistics
Automatic Rate Shopping On Every Order
You never have to manually choose a carrier. Mountainy's system compares all available carriers in real time and selects the lowest cost option for each shipment – UniUni included.
Real-Time Comparison
Rates are compared at the moment of fulfillment – not cached – so you always get the most accurate pricing.
Zero Manual Work
Our WMS handles carrier selection automatically. You focus on growing your brand, we handle the logistics.

Ideal Use Cases
UniUni Is the Best Choice When…
Not every shipment is a UniUni shipment - but when the conditions are right, it's the smartest option in our network.
Urban & Suburban Destinations
Your customer is in a major metro area or its suburbs — exactly where UniUni's network is strongest and most cost-effective.
Small Parcel, High Volume
You're shipping hundreds or thousands of lightweight packages per month — the volume where UniUni's per-unit savings really compound.
Cost-Sensitive Brands
You want to reduce shipping costs without sacrificing reliability — UniUni delivers comparable speed to USPS at a lower price point.
