StowPilot

An AI warehouse slotting and pick-path platform that re-slots SKUs by velocity, plans pick waves, and routes pickers on the shortest path — cutting walk distance per pick.

Client:3PL fulfillment operator (NDA)
Duration9 weeks
ScopeMVP product design and front-end build of the Warehouse Control dashboard and single re-slotting recommendation experience, backed by a velocity-scoring and shortest-path routing engine.

// The Warehouse Control board — facility KPIs, a 12-week walk-distance trend falling from 114 ft to 88 ft, and a re-slotting queue ranked by walk saved.

01In brief

If you read one part of this page, read these 4 lines.

  • Cuts average walk distance per pick from 114 ft to 88 ft by re-slotting the building
  • Turns velocity signals into ranked, one-click re-slotting moves for the ops lead
  • Routes every wave on the shortest serpentine path across each picker's aisles
  • Every move is explainable — feet saved, confidence, and the bin it picked and why
02Overview

What it does — and which part of it we built.

StowPilot gives a third-party logistics operator an AI control room for the pick operation.

It ranks every SKU by velocity into A/B/C classes, re-slots fast movers into golden-zone forward pick, batches orders into balanced waves, and sequences each picker on the shortest serpentine route across their aisles. BuildspaceLabs designed and built the MVP front end — a Warehouse Control dashboard for facility-wide triage and a single re-slotting recommendation view that draws the before/after bin on a warehouse aisle grid — turning a slotting-optimization engine and a stream of pick history into moves an ops lead can approve in seconds.

04Outcomes

What the engagement left the client with.

  • Delivered a production-quality MVP of the Warehouse Control board and re-slot detail view in a 9-week engagement
  • Consolidated slotting, wave planning, and pick routing into a single ops-lead workflow
  • Cut modeled average walk distance per pick from 114 ft to 88 ft across the facility
  • Established a reusable design system (velocity pills, aisle-grid map, confidence bars) for the product's next surfaces

Every feature in the build (6)
  • Warehouse Control board with live orders-in-wave, pick rate, walk-per-pick, and slot-utilization KPIs
  • Velocity re-slotting engine that ranks SKUs into A/B/C classes and suggests moves by walk saved
  • Shortest-path pick routing that sequences each wave into a single serpentine per picker
  • Wave planning that batches orders by zone and cart to stop aisle backtracking
  • 12-week walk-distance-per-pick trend chart and facility slot-utilization tracking
  • Re-slot detail with a warehouse aisle grid, projected savings, pick-frequency sparklines, and an explainable rationale
