The economics
Pick labor is typically the largest variable cost in a DTC warehouse. A poorly designed pick path adds 15-30 seconds per order through unnecessary travel; multiply by your daily order volume and the number becomes alarming.
At 2,000 orders a day, a 20-second improvement saves over 10 hours of labor daily.
Design principles
Three principles drive good pick path design: 1) High-velocity SKUs at the start of the path, near packing. 2) Zone-based picking when order complexity rises. 3) Batch picking for multi-item orders.
Each principle interacts with your WMS configuration; this is where a specialist earns their fee.
When to redesign
Redesign pick paths after major SKU catalog changes (new product launches that shift velocity), warehouse moves, peak season prep, or whenever cycle time creeps up by more than 10% with no obvious cause.
The redesign itself usually takes 1-2 weeks of analysis plus a weekend of physical relocation.
Tooling support
Manhattan, Logiwa, and ShipHero all support pick path optimization at the WMS level. ShipStation and Shopify do not. The presence (or absence) of native pick path support is one of the strongest signals that you have outgrown a shipping-only tool.
