Put Wall Systems for High-Density Order Sortation
A put wall system is a high-density order consolidation station used after batch picking. Voodoo turns standard shelving into a wireless put wall with light-directed displays, helping warehouses sort orders faster, more accurately, and without wiring. A warehouse put wall is a specific, stationary implementation of put-to-light — engineered for fast put wall order consolidation at scale.
Scan. Light. Place. Confirm.
A streamlined put wall workflow that turns high-density order sortation into a fast, error-free process — powered by wireless displays and a simple WMS integration.
Outfit the Wall
Shelving or cubbies are outfitted with wireless Voodoo displays — one per compartment. Mount with adhesive or magnets in minutes.
Scan the Item
Operator scans a pre-picked item at the put station. The system identifies which order the item belongs to.
Follow the Light
The correct compartment display lights up with order info and quantity. No guesswork, no searching.
Confirm Placement
Operator places the item and confirms with a button press. The system tracks order completion in real time.
Why Teams Choose Wireless Put Walls
Traditional wired put wall systems require expensive infrastructure and weeks of installation. Voodoo's wireless put wall system deploys in minutes and scales on demand.
Kenco Deploys Voodoo Put Walls for Peak-Season Throughput
"Kenco deployed the Voodoo Robotics system to increase efficiency and help with bottleneck issues during peak season."
Kenco Logistics Services — a leading third-party logistics provider — uses Voodoo Cloud Display Devices in a put wall with high-volume SKUs. The display lights up the tote to pick from on the put wall with a light, text, and quantity, then instructs the packer to remove the tote and pack the product into a shipping container. The hybrid solution combines handpicked totes with containers delivered by Locus Robots onto the conveyor line.
Kenco featured the deployment in its Ahead of the Curve booklet as an example of how wireless put wall systems keep multi-client 3PL operations running smoothly at peak.
Read the Kenco put wall storyWhen to Use a Put Wall
- ●High-density order sortation — 200+ simultaneous orders per wall
- ●Post-batch-pick sorting where items need allocating to individual orders
- ●Multi-client 3PL operations with different client profiles each wave
- ●eCommerce peaks (Prime Day, BFCM) when order volume spikes 5–10×
- ●Retail store replenishment — sort-to-store from distribution centers
Why Wireless Put-to-Wall
- ●Mount displays on existing shelving — no specialized furniture required
- ●No wiring to each cubby — zero electrician time, zero conduit
- ●Reconfigure compartments and wall layouts in minutes, not days
- ●Deploy a full sort wall in hours — go live the same day
- ●Scale wall size up or down per season with no infrastructure changes
What It Integrates With
- ●Any WMS via standard REST API — JSON over HTTPS
- ●Barcode scanners for item identification before sort placement
- ●Upstream pick-to-light for a complete batch pick → wall sort workflow
- ●Downstream pack-to-light for final ship verification
- ●Cloud dashboard for real-time sort rate, accuracy, and wall utilization
Put Walls vs. Other Workflows
A put wall — also called a sort wall or put-to-wall — is a physical implementation of the put-to-light workflow. Here's how it fits alongside other approaches.
Put Walls vs. Pick to Cart
Put walls sort items at a stationary wall after batch picking — ideal for high-density operations handling 200+ simultaneous orders. Pick-to-cart (cart-based picking) combines picking and sorting on the move, which suits smaller order volumes and dynamic layouts. Put walls win on throughput; pick-to-cart wins on flexibility.
Put Walls vs. Put to Light
Put-to-light (sort-to-light) is the workflow method — displays guide operators when placing items into order locations. A put wall is one physical form of that workflow: shelving with compartments and displays. Put-to-light can also run on carts, conveyor lanes, or temporary staging — the put wall is the highest-density stationary version.
Put Walls vs. Batch Picking Alone
Batch picking without a put wall still requires a downstream sort step — usually manual and error-prone. Adding a wireless put wall to the end of a batch pick run turns unguided sorting into a light-directed, verified process. The wall eliminates sort errors and gives the WMS real-time order completion visibility.
Put Walls Across Industries
Any operation that sorts items into multiple destinations benefits from a put wall system. Here are the most common applications.
3PL Multi-Client Fulfillment
Sort orders for multiple clients simultaneously on a single wall. Reassign compartments as client volumes shift — no rewiring, no downtime.
eCommerce High-Volume Sortation
Process hundreds of orders per wave with light-directed accuracy. Operators sort items at speed without memorizing bin assignments.
Pharmaceutical Distribution
Maintain lot tracking and expiry compliance during order sortation. Displays show lot numbers and quantities for every placement.
Retail Store Allocation
Allocate inventory across dozens of store locations on a single put wall. Each compartment represents a store, and displays guide the breakdown.
Subscription Services
Build subscription boxes efficiently by sorting components across active subscriber orders. Reconfigure the wall each cycle as subscriber counts change.
