What makes StoaPack different

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

Multi-warehouse

Cross-location optimization

Routes items to the optimal warehouse combination and returns the solution with the fewest total packages. Send inventory from 2, 5, or 20 warehouses in a single API call.

AI-powered

Natural language packing rules

Say "keep batteries separate from liquids" or "heavy items on the bottom" in plain English. StoaPack translates instructions into packing constraints automatically.

Real-world results

How StoaPack reduces shipping costs in practice.

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

2 packages instead of 4. Fewer shipments, lower cost, one warehouse fulfills the entire order.

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

18% average reduction in box volume. Less void fill, lower dimensional weight charges.

3PL with hazmat items

Without StoaPack

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

With StoaPack

StoaPack auto-classifies hazmat items by UN number and enforces segregation rules in the packing solution.

Result

Automated 49 CFR compliance. No manual lookup, no segregation errors, audit-ready packing data.

Simple, transparent pricing

All plans include a 30-day free trial. Cancel anytime.
