What makes StoaPack different

Capabilities you won't find in basic bin packing tools.


Illustrative packing scenarios

Hypothetical examples, not customer results or live API output. Every count, utilization figure, and savings percentage is illustrative; actual costs and outcomes depend on your shipment.

Multi-warehouse e-commerce

Without StoaPack

You have inventory in 3 warehouses and a 6-item order. Your system ships 4 packages from 2 locations.

With StoaPack

StoaPack finds the warehouse combination that fills 2 boxes at 94% utilization.

Result

Illustrative: 2 packages instead of 4. In this hypothetical example, one warehouse fulfills the order. Actual shipping costs vary.

Subscription box fulfillment

Without StoaPack

You ship 1,200 subscription boxes monthly. Each box is a standard size, regardless of the items inside.

With StoaPack

StoaPack selects the optimal box size for each order's unique item combination, applying fill percentage for padding.

Result

Illustrative: 18% reduction in box volume. A hypothetical outcome, not a measured average or guaranteed reduction in carrier charges.

3PL with hazmat items

Without StoaPack

You fulfill orders containing lithium batteries and aerosols. Manual compliance checking adds handling time.

With StoaPack

StoaPack uses supported UN references and supplied hazmat data to apply supported segregation checks in the packing solution.

Result

Hazmat-aware packing support. Qualified shipper review is still required. Checks do not cover every regulation, carrier restriction, packaging requirement, label, or document.
