Dynamic Rate-Shopping.
Lowest Cost Guaranteed.
Stop overpaying for shipping labels. Our engine rate-shops across your entire courier network in real-time, leveraging exact parcel dimensions, actual weight, and delivery SLAs to guarantee the lowest cost to the door.
Stop paying for air.
Most WMS platforms select a shipping rate based purely on the physical weight of the items. When the carrier measures the box, you get hit with massive Dimensional (DIM) Weight chargebacks.
Because our Shipping module sits directly downstream of our 3D Packing Engine, we query carrier APIs with the exact mathematical volume of the carton being used. You rate-shop with perfect physical data, eliminating chargebacks entirely.
Intelligent Carrier Routing
Every parcel is evaluated against thousands of permutations in milliseconds to find the perfect label.
Live Rate Shopping
We ping your configured carrier APIs instantly. No more relying on outdated static rate tables that miss dynamic pricing discounts.
Zone Skipping Logic
The engine understands complex postal matrices, automatically upgrading or downgrading services based on regional geographic proximity to save margins.

If a customer paid for Next-Day, the engine automatically filters out any carrier or service level that cannot guarantee delivery by the required date.
