In most warehouses, workers spend their days walking miles between storage racks and packing stations, creating bottlenecks that slow down order fulfillment and increase labor costs. Every additional touch point in the process adds time, expense, and opportunities for error.
But what if you could combine picking, consolidation, and packing into one seamless operation?
Traditional pick and pack methods require multiple handling steps, but pick-to-box eliminates these inefficiencies by placing items directly into shipping containers during the initial collection process.

Pick-to-box explained: The one-touch fulfillment method
Pick-to-box is a warehouse method where workers place items directly into the final shipping carton during the pick run. Unlike traditional order picking systems where items are collected in totes or carts and later transferred to packing stations, pick-to-box eliminates that second handling step entirely.
The core principle revolves around combining “Pick, Consolidate, and Pack” into one fluid operation. Think of it like grocery shopping directly into reusable bags instead of using a cart and bagging everything later at the checkout. The worker receives an optimized route through the warehouse with pre-sized shipping boxes, places each item directly into its final shipping container, and completes the order without additional handling.
PRO TIP: Pick-to-box works best when your WMS can accurately predict box sizes before picking begins. This “cartonization” process is crucial for success.
How the pick-to-box process works step-by-step
Understanding the on-the-floor journey of a single order reveals how pick-to-box creates efficiency gains throughout your warehouse operations.
Step 1: Order In, Box Out (Cartonization) The WMS analyzes an order’s items—considering weight, dimensions, and special handling requirements—to pre-select the most efficient shipping box before picking begins.
Step 2: The Pick Path Assignment The worker receives picking instructions via an RF scanner or mobile device, gets assigned their pre-sized shipping boxes, and receives an optimized travel path through the warehouse.
Step 3: The Pick-and-Pack Action Here’s where the magic happens: the worker scans the bin location, scans the item to verify accuracy, and places it directly into the correct shipping carton on their mobile cart. This represents the perfect marriage of traditional pick and pack efficiency with modern order picking optimization.
Step 4: Finalize and Ship Once the last item is picked, the box is essentially complete. The worker adds protective dunnage as needed, seals the box securely, and applies the shipping label.
Pick-to-box vs. other picking methods (batch, wave, & zone)
Selecting the best order picking method depends on your warehouse’s specific order profiles, inventory characteristics, and operational goals.
Comparison of picking methods
| Method | Core Concept | Best For | Key Advantage |
|---|---|---|---|
| Pick-to-Box | Pick directly into shipping cartons | Multi-item ecommerce orders | Eliminates packing station |
| Batch Picking | Pick multiple orders simultaneously | High-volume, similar items | Maximizes efficiency |
| Zone Picking | Divide warehouse into zones | Large warehouses, diverse SKUs | Reduces travel time |
| Wave Picking | Process orders in scheduled waves | Predictable order patterns | Optimizes labor scheduling |
| Pick and Pack | Pick to totes, then pack separately | Complex packaging requirements | Specialized packing expertise |
Understanding pick and pack vs. pick-to-box
The most common point of confusion involves distinguishing between pick and pack and pick-to-box methods. While both handle order fulfillment, traditional pick and pack involves a two-stage process where items are collected into temporary containers, then sent to a separate packing station. Pick and pack methods require dedicated staff to transfer items into shipping boxes and prepare final packages.
Pick-to-box eliminates this handoff entirely. The worker becomes both collector and packer, handling items just once as they move directly from storage location to shipping container.
The core advantages & disadvantages of pick-to-box
A balanced evaluation of pick-to-box helps warehouse managers make informed decisions about whether this method aligns with their operational goals.
Advantages
Reduced Labor and Travel Time Eliminating the packing station cuts both labor touches and travel time significantly. Research shows that workers can walk 6-9 miles daily in traditional setups², and pick-to-box substantially reduces this travel by combining picking and packing motions.
Increased Accuracy Fewer touches mean fewer opportunities for errors. When items move directly from shelf to shipping box, there’s no chance for mix-ups during transfer from pick tote to packing station.
Material & Cost Savings Smart cartonization can reduce packaging material and shipping costs by up to 30%¹. By selecting optimal box sizes before picking begins, warehouses eliminate oversized packages.
Disadvantages
Order Profile Limitations Pick-to-box isn’t ideal for single-item orders or very large, complex orders that require extensive packaging expertise.
Cartonization Complexity Success requires a powerful WMS with sophisticated cartonization algorithms and highly accurate product dimension data.
ALERT: Poor product data quality is the number one reason pick-to-box implementations fail. Invest in accurate measurements before starting your pilot program.
When does pick-to-box make sense for your warehouse?
Determining whether pick-to-box aligns with your operation requires honest evaluation of your current order patterns and operational challenges.
Your Order Profile Checklist:
You process high volumes of small, multi-line orders (typically 3-8 SKUs per order)
Most orders contain items that pack well together without special handling
Single-item orders represent less than 30% of your volume
Your Current Pain Points:
Packing stations create the biggest bottlenecks in your operation
Labor costs for traditional pick and pack operations are higher than industry benchmarks
Order accuracy issues often occur during handoffs
You’re struggling to scale fulfillment during peak seasons

Technology that unlocks pick-to-box efficiency
Pick-to-box success depends on specific technologies working together seamlessly to orchestrate the entire fulfillment process.
The brain (WMS)
A robust WMS with strong cartonization algorithms is absolutely non-negotiable for pick-to-box operations. This foundational technology is essential for most modern third-party logistics (3PL) providers.
The WMS must analyze each order’s items in real-time, considering dimensions, weight, and fragility to select the optimal shipping container before picking begins.
The hands (picking technology)
Hardware options guide workers through the optimized process efficiently. RF scanners provide reliable barcode scanning and order instructions, while pick-to-light systems offer visual guidance for high-density pick zones.
NOTE: Modern pick-to-box operations often integrate with ecommerce fulfillment platforms to provide real-time order status updates.
