4ember / Stowline
In development

See the load before it's loaded.

Stowline is a visual load-planning tool for freight teams. It doesn't replace your transport system; it fills the gap most of them leave: how each load actually fits in the trailer, in what order, and who needs to know.

The problem

Plans live in heads and spreadsheets.

Carriers already run big systems for bookings, accounting and customs. But how the trailer is packed is usually decided on the dock, by memory. Mistakes show up as wasted space, re-handling at delivery, and calls to the driver.

Three screens, one plan

The same plan, sized for each job.

Office

Plan

Edit on a precise 2.5D view, check the result in 3D. Live weight and volume, a suggested layout by delivery order, and the planner has the final say.

Dock

Load

The warehouse sees the 3D plan and a loading list in the right order, so the trailer is packed the way it was planned.

Road

Deliver

An offline-first driver app with the trip, stop order, layout, status updates and document photos. It syncs when the signal comes back.

Data model

One plan in the middle.

Loads arrive from wherever the customer keeps them. They are translated into one canonical contract, planned once, and every screen reads the same plan.

Optional write-back sends plan, status and proof of delivery to the customer's own system.

Built to fit in

Start without replacing anything.
