# Stowsmith

> Stowsmith calculates how goods are best stowed: identical cartons on pallets (layer patterns, cartons per pallet, height and weight limits), products in totes and bins of any kind, and orders of mixed items in the fewest or cheapest shipping cartons, with cut-down carton heights. Every answer comes with a bound, so you can see when no better answer exists. It runs as a web app, batch CSV files, a command line tool, a Python package, and a Rust and WebAssembly library with JSON in and out.

Stowsmith is a product of Diteva AB, a limited company registered in Sweden. Trials run on a sample of the customer's own data. Prices are not published on the site. Contact: hello@stowsmith.com.

Every number on stowsmith.com is a real engine result or a published benchmark result. Examples: a 302 × 136 × 168 mm carton fits 212 per EUR pallet at 1 800 mm where the master data said 144; 1 500 articles are validated in 0.02 seconds; 35 cartons of 170 × 120 × 90 mm fit a 650 × 450 × 330 mm storage tote; of 2 000 sample orders, over 90 % are proven to use the fewest cartons possible.
