Walmart's Route Optimization technology — now available as SaaS — helps Home Depot target same-day delivery for 90% of the U.S.

Background

Operating one of the world's largest logistics networks, Walmart faced the dual challenge of reducing the cost and environmental impact of last-mile delivery while maintaining availability across 4,700+ stores. Optimizing routing at that scale — accounting for package details, traffic conditions, delivery windows, and parking logistics — is computationally intensive. Walmart built this capability internally and eventually recognized it as a commercial asset.

What Was Implemented

• AI-driven route optimization system that minimizes miles traveled, packs trailers efficiently, and accounts for traffic and delivery constraints
• Spark Driver app integration for independent contractor delivery routing
• Sortation centers that sort packages by ZIP code and consolidate multi-order deliveries
• GoLocal platform: delivery-as-a-service for third-party retailers using Walmart's infrastructure
• Commercial launch as SaaS via Walmart Commerce Technologies (March 2024)
• Home Depot integration: 300+ store locations for same-day and next-day delivery

Results

Walmart's route optimization eliminated 30 million unnecessary miles and prevented 94 million pounds of CO₂ emissions . The system won the 2023 Franz Edelman Award . GoLocal's same-day delivery on-time rate is 98.5% . The Home Depot's GoLocal deployment supports its goal of reaching 90% of the U.S. population with expedited delivery.

Lessons

• Logistics technology built at proprietary scale can become a commercial product — Walmart's transition from internal tool to SaaS offering is a replicable model for large operators
• Route optimization that integrates multiple constraints (packages, traffic, parking, delivery windows) substantially outperforms simple distance minimization
• Sustainability metrics (CO₂, miles) are increasingly core to business case construction for logistics optimization
