Your warehouse isn’t slow because your team isn’t working hard. It’s slow because they’re working inefficiently. When every picker is chasing orders in random directions, you lose time, increase errors, and risk customer satisfaction.
Wave picking fixes that by turning chaos into coordination. By grouping orders for optimized picking routes and releasing them in scheduled “waves,” you can streamline picking, reduce walking time, and enhance picking speed, especially in high-volume eCommerce environments.
In this guide, we’ll explain what wave picking is, how it works, and how to use it to run a faster, leaner, and more accurate warehouse.
What is Wave Picking?
Wave picking is a warehouse picking strategy where orders are grouped and released in scheduled “waves” throughout the day. Each wave organizes orders based on factors like delivery time, product type, or warehouse zone, to help your team pick faster, move smarter, and stay organized. When paired with automated warehouse picking systems, wave picking becomes even more powerful, and minimizes manual effort while maximizing speed and accuracy.
For example, a warehouse might group all orders that need same-day shipping into a morning wave, while standard shipping orders are picked in the afternoon. This keeps the flow structured and reduces chaos on the floor.
Brands using wave picking have seen measurable results. A study published in Acta Logistica found that accurately batching and releasing orders in structured waves reduced cycle times by more than 13% compared to unplanned methods, proving how it standardizes warehouse processes and improves resource utilization. This demonstrates how even modest changes in picking structure can lead to significant gains in warehouse efficiency.
How Does Wave Picking Work?
Wave picking operates through a structured, three-phase process: pre-wave, wave, and post-wave.
Each stage plays a critical role in coordinating order fulfillment, from organizing batches of orders to guiding pickers efficiently through the warehouse and ensuring fast, accurate packing and shipping. Understanding how each phase works is key to unlocking the full efficiency potential of wave picking.
Before picking begins, the warehouse management system (WMS) organizes inventory for efficiency by grouping orders into waves based on factors like shipping deadlines, SKU type, or zone. It then generates batch pick lists, allocates resources, and ensures that equipment and carts are ready, laying the groundwork for a smooth picking process using proven picking strategies.
Good Company, a 3PL provider, exemplified this by leveraging ShipHero’s multi-item batch feature. This streamlined their pre-wave setup, enabling them to group multiple orders with shared items into single picking runs. This drastically reduced picker travel, and as they scaled from 500-600 to 6,000-10,000 units daily within 18 months, allowed them to halve their pick time. This demonstrates the immense power of an optimized pre-wave process.
Performing Wave Picking
Once a wave begins, pickers follow optimized routes through the warehouse to collect items. The goal is to reduce backtracking and congestion by assigning pickers to specific zones or paths.
E-Commerce Xpress, an eCommerce fulfillment provider, has significantly streamlined its picking process by adopting ShipHero’s Warehouse Management System (WMS). Their previous manual methods caused inefficiencies and excessive picker travel. By using ShipHero’s multi-batch order feature, they transformed their picking phase. This technology groups multiple orders into single runs, creating highly optimized routes and eliminating unnecessary trips. The result was profound: E-Commerce Xpress could fulfill 200 orders in just 2 hours with one person, a task that previously required four staff members 4-5 hours. This showcases how wave picking handles peak operational loads and supports multi-order fulfillment with ease.
Post-Wave Picking
After items are picked, they move to packing and shipping. This phase includes labeling, verifying accuracy, and dispatching the final product. A well-organized post-wave process ensures orders are completed on time and without mistakes.
Consider Vareya, a 3PL and fulfillment company, which dramatically improved its post-wave efficiency and client satisfaction by adopting ShipHero’s Warehouse Management System (WMS). Previously, Vareya struggled with disconnected systems, resulting in significant errors and excessive paperwork. By migrating to ShipHero, they automated workflows and shipping labels, ensuring efficiency and accuracy in packing and dispatch. This allowed them to triple business volume and meet customer service levels consistently.
How to Do Wave Picking Effectively
To get the full benefits of wave picking, it’s essential to follow proven best practices that align your people, tools, and workflows. From using the right technology to organizing pick paths and handling carts efficiently, these core strategies—like those in our warehouse picking strategies guide—will help you maximize speed, accuracy, and productivity in every wave.
Use a Warehouse Management System (WMS)
A powerful WMS like ShipHero automates wave creation, drives real-time decision-making, and optimizes paths. It ensures every wave is precisely executed and synced with inventory.
Calculate optimal picking routes
Calculating optimal picking routes is one of the most effective ways to reduce travel time on the warehouse floor, a major contributor to inefficiency. By using route optimization software, pickers follow the shortest and most logical paths through the facility, thereby avoiding unnecessary backtracking and congestion. This not only speeds up fulfillment but also reduces fatigue and boosts overall productivity, especially in high-volume environments where every second counts.
Define cart handling strategies
Efficient cart handling is key to successful wave picking. Organizing carts by order, zone, or SKU reduces sorting time and speeds up packing. This keeps the workflow smooth, reduces errors, and enhances overall fulfillment efficiency.
Types of Wave Picking
Wave picking comes in different forms, each suited to specific warehouse needs. Whether you’re handling large SKU volumes, urgent orders, or multiple zones, choosing the right strategy can boost speed, accuracy, and efficiency.
By Product Type
Organizing wave picking by product type allows warehouses to group similar SKUs into the same wave. This reduces picker travel time, as items are often stored near each other, and enables faster, more efficient picking by creating consistent, repeatable paths through the warehouse. It’s especially useful for high-assortment operations where grouping like products streamlines the process.
By Order Priority
Wave picking by order priority ensures that urgent orders, such as express shipments or VIP customers, are grouped and processed first. By releasing these high-priority orders in the earliest waves, warehouses can ensure faster turnaround times and meet strict delivery deadlines, thereby maintaining high customer satisfaction and consistent service levels.
By Picking Zones
Dividing the warehouse into picking zones allows each wave to focus on a specific area, reducing unnecessary movement and streamlining the picking process. Assigning pickers to dedicated zones allows waves to run simultaneously in different zones, reducing congestion and enabling scalability in operations.
4 Benefits of Wave Picking in a Warehouse
Wave picking is a fulfillment strategy designed to group orders into scheduled “waves” based on factors like shipping deadlines, product locations, or customer types.
This method is especially valuable in high-volume or time-sensitive operations where precision and speed are critical. Below are four key benefits of using wave picking in your warehouse:
Improved Warehouse Efficiency and Storage
Wave picking keeps operations structured, which allows you to process more orders per shift without expanding your physical footprint.
Faster Order Fulfillment
By reducing idle time and unnecessary movement, wave picking streamlines the entire fulfillment process. After adopting ShipHero’s WMS, American Tall saw a 275% increase in picking efficiency and cut fulfillment errors by 50%, allowing them to scale operations by 400%—clear proof of how structured picking methods lead to faster, more reliable order delivery.
Minimal Operational Errors
With batch pick lists, scanning, and real-time tracking, wave picking drastically reduces errors in item selection and order completion.
Reduced Overhead
Fewer errors, faster picks, and optimized labor use = lower costs. Wave picking helps you do more with fewer resources.
Wave Picking vs. Batch Picking
The main difference between wave picking and batch picking lies in their timing and level of structure. Wave picking organizes and releases orders at scheduled times throughout the day, which is ideal for high-volume warehouses where precise timing and a smooth workflow are essential. This method offers a structured approach that reduces errors and supports scalability, but it requires more upfront planning and a reliable warehouse management system.
In contrast, batch picking allows warehouse staff to pick multiple orders in a single trip without being tied to a specific schedule. It’s a simpler, more flexible method that’s well-suited for smaller operations with lower order complexity.
While batch picking is easy to implement and has a lower barrier to entry, it becomes less efficient when dealing with large volumes or time-sensitive orders. Choosing the right approach depends on your warehouse size, order volume, and fulfillment goals.
