Have you ever wondered how online orders move from a massive warehouse shelf to your doorstep in just a day? Behind that speed is a process called warehouse picking — the heart of every successful fulfillment operation. Studies show that picking can account for over 50% of total warehouse labor costs, making it one of the most critical and costly steps in logistics.
Warehouse picking is the process of locating and collecting the right products to fulfill customer orders. It plays a vital role in e-commerce, logistics, and third-party fulfillment (3PL) services, where accuracy and speed directly influence customer satisfaction. A single mistake in picking can delay shipments or send the wrong product — both of which hurt customer trust.
In this post, you’ll learn everything about warehouse picking — from its methods and challenges to how modern automation and conveyor technologies are transforming warehouse efficiency. We’ll also explore how Longwei’s innovative conveyor systems are helping warehouses worldwide streamline their operations, improve accuracy, and handle growing order volumes with ease.
Imagine walking into a giant warehouse filled with thousands of different products. Somewhere inside, there’s a single item waiting to be sent to a customer. Warehouse picking is the process of finding that item and getting it ready for shipment. It sounds simple, but when hundreds or thousands of orders come in every day, the process becomes complex and crucial.
Warehouse picking means selecting the correct products from storage locations to complete customer orders. Workers or automated systems move through aisles, pick the right items, and send them to the next step — packing. It’s the heartbeat of order fulfillment. When picking works well, customers get their packages fast and correctly. When it doesn’t, delays and errors happen.
Here’s a simple overview:
| Step | What Happens |
|---|---|
| 1. Order received | Warehouse system creates a picking list |
| 2. Items located | Pickers or robots go to product locations |
| 3. Items picked | Products scanned and placed in totes or carts |
| 4. Sent for packing | Picked goods move to the packing area |
These three terms often sound similar, but they serve different purposes:
Picking – finding and collecting items from storage.
Packing – protecting and preparing items for shipment.
Sorting – grouping orders by destination or delivery type.
Think of it this way: picking gets the right items, packing makes them safe, and sorting makes sure they go to the right place.
Picking sits in the middle of the supply chain — right between inventory storage and order shipping. It connects what’s in the warehouse to what customers receive. It affects everything: speed, accuracy, labor cost, and even customer loyalty. Many modern warehouses use scanners, conveyor lines, and robots to make picking faster and less error-prone.
Let’s say a customer orders a pair of shoes online. The system sends the order to the warehouse. A picker or robot gets a digital picking list. It moves to the shoe section, scans the barcode, and picks the right pair. The item goes onto a conveyor system, moves to the packing area, and then on to sorting for final shipping. Within hours, the order is ready to leave the warehouse.
That’s warehouse picking — the quiet engine that keeps every online purchase moving smoothly.
Every order that leaves a warehouse starts with one simple step — picking. When it’s done right, everything flows smoothly. When it’s not, problems multiply fast. Efficient warehouse picking keeps operations moving, saves money, and keeps customers happy.
Picking often eats up the biggest share of warehouse labor. Studies show it can take up to 55% of total operating costs. That means even small improvements can create big savings.
Here’s how efficient picking makes a difference:
Higher accuracy → fewer returns and customer complaints.
Faster order processing → shorter delivery times.
Better use of labor → more output from the same team.
Improved space flow → fewer bottlenecks and smoother movement.
A warehouse that picks smartly moves more products, uses less energy, and delivers a better experience for everyone in the chain — from workers to customers.
| Metric | Traditional Picking | Optimized Picking |
|---|---|---|
| Picking speed (lines/hour) | 80–120 | 200+ |
| Error rate | 2–4% | <0.5% |
| Labor cost share | ~55% | 30–40% |
| Order cycle time | 1–2 days | Same-day |
Older picking systems depend heavily on people. It’s easy for errors to slip in. Pickers walk long distances, search for products manually, and double-check paperwork. That adds up to slower output and tired employees.
Some everyday pain points include:
Long travel time between aisles.
Unclear labeling or poor product placement.
Paper-based systems that delay updates.
Inconsistent training among staff.
Seasonal demand spikes that overwhelm manual systems.
These issues cause downtime, mispicks, and frustrated workers. They also drain profit margins over time.
Modern automation changes everything. Robots, conveyors, and smart sensors now handle much of the heavy lifting. They shorten travel distance, keep products moving, and allow workers to focus on quality checks instead of walking miles every shift.
Automated conveyor systems — like Longwei’s modular and sorting solutions — move picked items quickly to packing zones. This cuts idle time, reduces labor strain, and keeps a constant product flow.
Automation boosts performance in three major ways:
Speed: Continuous product movement instead of stop-and-go picking.
Accuracy: Barcode and RFID scanning confirm every item.
Scalability: Systems expand easily as order volumes grow.
Across the industry, the shift to automation shows measurable results.
| Improvement Area | Result After Automation |
|---|---|
| Picking speed | ↑ up to 300% |
| Order accuracy | ↑ from 96% to 99.8% |
| Labor cost | ↓ by 25–40% |
| Picking time per order | ↓ from 10 min to 3–4 min |
These numbers highlight how automated conveyors and intelligent picking systems transform warehouses. They turn once-slow processes into high-speed, error-free operations that keep up with modern customer demands.
Every order starts as a list of products waiting to be picked, packed, and shipped. The process may look simple on paper, but in a real warehouse, it involves careful planning and coordination. Let’s walk through how a typical warehouse handles picking from start to finish.
It begins when an order enters the system. The Warehouse Management System (WMS) receives customer requests and groups them into waves. A wave is a batch of orders scheduled for picking at the same time.
This planning stage helps balance workloads, reduce congestion, and make sure high-priority orders go first. Many modern WMS platforms use real-time data to release waves automatically based on product availability and carrier schedules.
Once orders are ready, the system assigns tasks to pickers or robots. Route optimization tools then find the shortest, most efficient path through the warehouse.
Here’s what happens behind the scenes:
The WMS analyzes storage zones.
It calculates the best picking path to reduce travel distance.
It assigns orders to workers based on skill level, equipment, or location.
Smart routing can cut picker walking time by over 30%, saving both energy and labor.
Now it’s time to pick. The picker follows the digital route on a handheld device or screen. Each location displays product details, quantity, and bin number. Barcodes or RFID tags confirm the correct item.
In automated warehouses, robots or conveyors deliver bins directly to the picker — a process known as “goods-to-person”. It eliminates long walking paths and keeps items flowing continuously.
| System Type | Who Moves? | Speed Level |
|---|---|---|
| Person-to-goods | Worker walks to items | Medium |
| Goods-to-person | Items brought to picker | High |
| Hybrid systems | Both automated and manual | Flexible |
After picking, each item goes through a verification step. Scanners or vision systems check barcodes to make sure the item matches the order.
If a mismatch happens, the system flags it immediately. This prevents costly packing errors later. Some warehouses use weight sensors or image recognition to confirm accuracy automatically.
Picked items move to the packing station through conveyor lines or carts. Here, workers or machines check condition, apply labels, and seal packages.
The system records each package’s status in real time. It then assigns the parcel to the correct staging area — ready for shipment. Using automated conveyors, this handoff happens quickly, keeping the workflow steady.
Once packed, products enter the sorting stage. Sorting conveyors group parcels based on delivery routes, carriers, or destinations.
High-speed sorters — such as Longwei’s Logistics Sorting Conveyor Line — can handle hundreds of packages per minute. They use sensors and smart controls to ensure each box reaches the correct dock or loading bay.
| Sorting Type | Best For | Technology Used |
|---|---|---|
| Manual sorting | Small operations | Barcode scanning |
| Semi-automated sorting | Mid-size warehouses | Gravity conveyors |
| Fully automated sorting | Large 3PL or e-commerce hubs | Intelligent conveyors + sensors |
A strong Warehouse Management System (WMS) ties every step together. It tracks inventory, monitors worker performance, and updates order statuses instantly.
Integration helps warehouses:
Eliminate paper-based lists.
Sync picking, packing, and shipping in real time.
Analyze productivity and identify slow zones.
When WMS connects directly to conveyors, scanners, and robotics, picking becomes faster, smarter, and nearly error-free.
Not all warehouses pick the same way. The best method depends on how many orders come in, how products are stored, and how fast they need to move. Below are the main warehouse picking methods used across industries today.
Discrete picking, sometimes called single-order picking, is the simplest method. One picker completes one order at a time. It’s easy to understand and requires little technology.
This method works best for:
Small warehouses or low daily order volumes
Made-to-order operations
High-value or customized products
Pros:
Simple to manage
Low setup cost
High accuracy for small batches
Cons:
Lots of walking
Low productivity in busy operations
| Best For | Order Volume | Technology Level |
|---|---|---|
| Small retailers | Low | Manual or basic WMS |
In batch picking, one picker handles multiple orders at the same time. Instead of walking the same route many times, they collect all the items for several orders in one pass.
It saves time and travel distance, especially for warehouses that process many small orders.
Efficiency Tips:
Group orders that share the same SKUs.
Use digital picking lists or smart carts.
Pair it with conveyors to speed up item delivery to pack stations.
Example:
A picker collects 20 of the same phone cases for 10 different customers in one trip instead of walking the aisles ten times.
| Ideal Use Case | Benefit |
|---|---|
| E-commerce, fast-moving items | Cuts walking distance by up to 50% |
Zone picking divides the warehouse into zones. Each picker is responsible for one zone and picks only items stored in that area. Orders move from one zone to another until complete.
It’s like an assembly line for order fulfillment. This approach reduces congestion and keeps workers focused on a small area.
Advantages:
Shorter travel distance per picker
Better organization for large spaces
Works well for conveyor-assisted systems
Coordination Tip:
Use light or voice systems to alert pickers when an order enters their zone. The WMS tracks progress as the order moves through each area.
| Warehouse Size | Zone Count | Typical Setup |
|---|---|---|
| Large or multi-level | 3–10 zones | Conveyors or sorting lanes |
Wave picking combines planning and timing. Orders release in waves at specific times based on shipping schedules, carriers, or priority levels.
It syncs picking, packing, and shipping for smooth, predictable workflows. Large warehouses often use wave picking to align labor and equipment availability.
How it works:
WMS groups orders by delivery type or destination.
Orders release in time blocks (waves).
Pickers collect items during that scheduled wave.
Benefits:
Better workload control
Easier coordination between departments
Ideal for high-volume operations
| Wave Type | Purpose |
|---|---|
| Carrier-based | Match delivery cutoffs |
| Product-based | Handle similar SKUs together |
| Time-based | Balance workloads during shifts |
Cluster picking lets a worker pick items for multiple orders at once using a cart or mobile station. Each slot or tote represents one order.
It’s faster than discrete picking and simpler than batch picking. It suits warehouses handling medium order volumes and many SKUs.
Tools That Help:
Multi-bin picking carts
Pick-to-light displays
Conveyor drop-off stations
Example:
A picker stops at one shelf and grabs different SKUs for six orders stored in separate bins on their cart.
| Order Type | Best Tool |
|---|---|
| Multi-SKU, small orders | Light-guided picking carts |
Automation takes picking to the next level. Automated Picking Systems use robotics, sensors, and data-driven algorithms to move goods efficiently. These systems work almost nonstop and reduce manual labor.
Common types include:
AS/RS (Automated Storage and Retrieval Systems): Robots or cranes bring items to pick stations.
AMRs (Autonomous Mobile Robots): Mobile robots transport bins or shelves to workers.
Conveyor-integrated systems: Conveyors like Longwei’s automated sorting lines deliver picked items directly to packing stations.
Benefits:
Faster throughput and 24/7 operation
Fewer picking errors
Scalable for future growth
| System Type | Automation Level | Efficiency Gain |
|---|---|---|
| AS/RS | High | Up to 400% faster than manual |
| AMR-based | Medium–High | Reduces travel by 60% |
| Conveyor-integrated | High | Ideal for continuous picking flow |
Automation doesn’t replace people — it supports them. It reduces walking, improves accuracy, and keeps products moving smoothly through the warehouse.
Modern warehouses look very different from what they were a decade ago. Paper lists are gone. Now, lights, voices, scanners, and even AI systems guide workers through every pick. These technologies make picking faster, more accurate, and much easier to manage.
Pick-to-Light (PTL) and Put-to-Light (PTL) systems use lights and digital displays to guide workers. When an order arrives, lights on the storage racks turn on, showing where to pick or place an item. Workers simply follow the light, grab the product, and confirm by pressing a button.
How it helps:
Cuts search time and walking distance.
Reduces picking errors by more than 90%.
Easy to train new workers — no complex instructions needed.
| System Type | Main Action | Ideal Use Case |
|---|---|---|
| Pick-to-Light | Lights show where to pick | High-volume order zones |
| Put-to-Light | Lights show where to place | Order sorting stations |
This system works perfectly for e-commerce or fast-moving consumer goods, where every second matters.
Instead of looking at screens, pickers now listen to instructions. Voice-guided systems connect through wireless headsets, giving spoken directions like “Aisle 3, Bin 12, Pick 2.” Workers confirm by speaking back.
Wearable devices — such as wrist scanners, smart glasses, or finger-mounted sensors — take it one step further. They keep hands free and speed up work.
Why it works well:
Keeps both hands available for picking.
Speeds up movement by removing paper lists.
Fits well in temperature-controlled or dimly lit warehouses.
Example:
A cold storage picker wearing gloves can hear voice commands without touching a screen. It’s efficient and safer.
Barcodes and RFID tags help warehouses keep track of everything in real time. Pickers scan an item’s barcode or tag, and the system checks it instantly.
RFID (Radio Frequency Identification) goes beyond line-of-sight scanning. It can read multiple tags at once, even from a few meters away.
Benefits include:
Instant inventory visibility.
Real-time updates to WMS or ERP systems.
Lower chance of picking the wrong item.
| Technology | Scan Range | Use Case |
|---|---|---|
| Barcode | Short (line of sight) | Manual picking or small SKUs |
| RFID | Long (multi-item read) | Automated conveyor or pallet tracking |
Warehouses using RFID often pair it with automated conveyors or robotic sorters for seamless movement and verification.
AI and computer vision bring a new level of intelligence to picking. Cameras and sensors “see” each item, recognize shapes or labels, and verify accuracy automatically.
How it works:
Cameras capture item images.
AI compares them to product data.
The system confirms or corrects each pick in real time.
This technology reduces dependency on manual scanning and speeds up robotic picking arms or automated sorters. It’s especially useful for high-mix warehouses handling different shapes and sizes.
Key Advantages:
Near-zero human error.
Automatic defect or mismatch detection.
Ideal for integration into Longwei’s conveyor-based automation systems.
The real power of all these technologies comes when they connect through a Warehouse Management System (WMS) or Enterprise Resource Planning (ERP) platform.
Integration allows warehouses to:
Track inventory live.
Analyze pick rates, errors, and performance instantly.
Sync data between picking, packing, and shipping systems.
Coordinate automation equipment such as conveyors, sorters, and mobile robots.
| System Integration Level | Key Benefit | Technology Involved |
|---|---|---|
| WMS + Pick-to-Light | Real-time task updates | Light modules + WMS API |
| WMS + Voice Picking | Hands-free workflow | Voice headsets + mobile app |
| ERP + RFID | End-to-end tracking | RFID readers + ERP sync |
This real-time connectivity keeps everything aligned — people, robots, and machines — turning warehouse picking into a smooth, data-driven operation.
Conveyors sit at the center of modern warehouse automation. They move goods, connect workstations, and keep every picking process running smoothly. When designed right, they turn slow manual workflows into fast, synchronized operations. Longwei’s conveyor solutions combine speed, flexibility, and smart integration to create seamless material handling systems for warehouses of all sizes.
A well-planned conveyor system is like the warehouse’s bloodstream — it keeps products flowing. It reduces walking, prevents congestion, and supports faster sorting and packing.
Why conveyors matter:
Reduce manual labor – less lifting, pushing, or carrying.
Shorten pick paths – items move directly to the next station.
Improve sorting accuracy – sensors and scanners confirm every parcel.
Boost throughput – consistent movement keeps operations continuous.
| Key Benefit | Impact on Operations |
|---|---|
| Reduced labor demand | Fewer manual handling tasks |
| Faster order flow | Shorter processing times |
| Better space use | Optimized warehouse layout |
| Higher accuracy | Lower picking and sorting errors |
Integration Power:

This tight integration helps warehouses operate as one connected ecosystem — fast, flexible, and ready for the future.
A warehouse’s design can make or break its efficiency. Every step a picker takes, every conveyor movement, and every shelf placement affects how fast and accurately orders move. An optimized layout reduces waste, speeds up picking, and keeps workers safe and comfortable.
The shortest path isn’t always the fastest — it’s the smartest one. Pick path design means creating routes that let pickers move smoothly through the warehouse while avoiding backtracking or traffic jams.
Good path design helps:
Cut walking distance by up to 40%
Minimize congestion in busy aisles
Improve picking sequence accuracy
Meanwhile, SKU slotting determines where each product should go. Fast-moving items (A items) should stay near packing zones or conveyor entry points, while slower ones (C items) can sit farther away.
| SKU Type | Storage Zone | Access Frequency |
|---|---|---|
| A (High demand) | Near conveyors or docks | Very frequent |
| B (Moderate demand) | Mid-aisle or mid-level racks | Regular |
| C (Low demand) | Top shelves or back storage | Occasional |
Smart slotting often uses data from WMS to adjust placements automatically based on order patterns.
Efficiency isn’t just about speed — it’s also about comfort and safety. Ergonomics keeps workers healthy while improving accuracy.
Key ergonomic improvements:
Adjustable picking stations to reduce bending or stretching
Anti-fatigue mats near static work zones
Proper lighting and clear labeling for better visibility
Use of conveyors or lift assists to reduce manual carrying
Example:
Instead of bending to pick from the floor, workers can use Longwei’s modular conveyors to bring items to waist height. It reduces injury risk and keeps picking continuous.
| Ergonomic Feature | Worker Benefit |
|---|---|
| Adjustable height tables | Less strain, faster packing |
| Gravity conveyors | No heavy lifting |
| Voice or light picking | Eyes-free, hands-free workflow |
Modern warehouses combine conveyors and robotics to create fluid, automated layouts. Instead of fixed routes, conveyors guide product flow, while robots handle transport between zones.
How they work together:
Conveyors connect picking and packing areas.
Robots (like AGVs) handle item delivery to conveyors.
Sensors track product location in real time.
Design tip:
Place conveyors along major traffic routes and connect them to high-volume zones. It keeps movement continuous and avoids bottlenecks.
| Component | Role in Layout | Result |
|---|---|---|
| Conveyors | Main product highway | Smooth material flow |
| AGVs | Flexible transport | Adapts to volume shifts |
| Sorters | Direct parcels to lanes | Faster dispatch |
This blend of automation and smart design allows operations to scale without expanding floor space.
Warehouses aren’t static. Orders change daily, and layouts must adapt. Dynamic zoning uses software to reassign zones based on real-time workload, product velocity, or staffing. It helps balance tasks and avoid idle time.
Intelligent routing supports this by automatically finding the best paths for workers or robots based on live data. When one zone gets busy, tasks shift automatically to another.
Benefits of dynamic systems:
Balanced workload across teams
Reduced travel and waiting time
Real-time updates between WMS and automation equipment
Example:
During peak seasons, the system can expand fast-pick zones near conveyor belts and reassign slower zones to back areas — all without changing the physical layout.
An optimized warehouse layout combines smart path design, ergonomic stations, and automated flow — all driven by real-time data and adaptable zoning.
Even the best warehouses face picking problems. Small mistakes can quickly grow into big delays, extra costs, and unhappy customers. Understanding these challenges helps teams find better ways to fix them.
People still play a huge role in picking, and even skilled workers make mistakes. A wrong SKU, a missed scan, or picking from the wrong shelf can all cause returns and wasted time. Many warehouses rely on seasonal workers who get limited training, which adds more risk.
Common reasons for human error:
Unclear labels or poor lighting.
Inconsistent training for new hires.
Fatigue from long walking routes.
Quick Fix Ideas:
Use Pick-to-Light or Voice Picking systems for guidance.
Provide short, hands-on refresher sessions.
Rotate tasks to reduce repetitive strain.
| Problem Source | Effect on Operations | Simple Solution |
|---|---|---|
| Poor labeling | Wrong picks | Clear signage and barcode updates |
| Manual data entry | Delayed records | Use handheld scanners |
| Lack of training | Slow performance | On-the-job micro-training |
Finding and keeping warehouse staff has become harder. The work can be physical, repetitive, and time-sensitive. As e-commerce grows, demand rises while available labor shrinks.
Impact on warehouses:
Higher overtime costs.
Slower fulfillment during peak seasons.
More strain on existing workers.
Smart solutions:
Add automation and conveyors to reduce heavy labor.
Use flexible shifts and performance incentives.
Cross-train employees to handle multiple roles.
| Challenge | Effect | Technology Help |
|---|---|---|
| Staff shortage | Missed orders | Robotic picking systems |
| High turnover | Frequent training costs | Standardized WMS procedures |
| Burnout | Drop in accuracy | Ergonomic conveyors and tools |
When system data doesn’t match what’s on the shelf, picking slows down fast. Workers spend extra time searching or replacing items. Incorrect counts lead to backorders or duplicate shipments.
Main causes:
Manual updates instead of automated tracking.
Unrecorded returns or damaged items.
Inconsistent cycle counting.
Prevention tips:
Use RFID or barcode systems for real-time tracking.
Sync data automatically to the WMS.
Run regular stock audits in smaller zones.
| Error Type | Result | Prevention Method |
|---|---|---|
| Miscounted stock | Stockouts | Automated scanning |
| Unrecorded movement | Lost items | WMS-integrated conveyors |
| Delay in updates | Picking delays | Real-time data sync |
A poorly designed layout creates chaos. Pickers travel long distances, aisles get crowded, and products pile up in sorting zones. When flow stops, productivity crashes.
Common layout issues:
Overlapping pick paths.
Narrow aisles that block carts.
Disorganized storage of fast-moving SKUs.
Better layout ideas:
Redesign aisles for one-way flow.
Place conveyors near high-demand areas to move goods faster.
Apply ABC slotting to group popular products close to packing zones.
| Layout Problem | Effect on Efficiency | Fix |
|---|---|---|
| Long walking routes | Wasted time | Route optimization |
| Mixed fast/slow SKUs | Traffic jams | SKU slotting by demand |
| No automation | Manual delays | Add conveyors or AGVs |
When information lags between systems, everything slows down. Orders may show as “picked” before they’re packed, or inventory updates happen hours late. This gap creates confusion for both workers and customers.
Causes:
Outdated software integrations.
Lack of real-time syncing between WMS, ERP, and conveyors.
Manual data entry errors.
How to fix it:
Connect conveyors, scanners, and robots directly to WMS.
Use cloud-based systems for instant updates.
Enable live dashboards so supervisors can spot delays early.
| Data Issue | Result | Solution |
|---|---|---|
| Delayed updates | Wrong stock levels | Real-time WMS integration |
| System silos | Miscommunication | Centralized data network |
| Manual reporting | Human error | Automated status tracking |
Each of these challenges slows warehouse picking in different ways. The key is using automation, smart layouts, and connected data systems to keep every process moving smoothly.
Every warehouse wants faster picking, lower costs, and happier customers. The secret isn’t just in working harder — it’s in working smarter. These best practices help streamline operations and build a foundation for long-term efficiency.
Not every warehouse should pick the same way. The best method depends on your order volume, SKU variety, and layout size.
Examples of what works:
Discrete picking: small orders or high-value products.
Batch picking: many small, similar orders.
Zone picking: large facilities divided by product type.
Cluster picking: multiple orders picked in one trip.
| Order Profile | Recommended Method | Efficiency Impact |
|---|---|---|
| Low-volume / high-value | Discrete | High accuracy |
| High-volume / low-SKU | Batch or Wave | Reduced travel time |
| Multi-zone warehouse | Zone | Balanced workloads |
| Multi-order mix | Cluster | Faster pick completion |
Choosing the right system helps reduce travel time, improve order accuracy, and balance the workload across teams.
Automation doesn’t mean replacing people — it means helping them do more. Conveyors, robotic sorters, and mobile robots (AGVs) reduce repetitive tasks and keep products moving.
Smart automation strategy:
Start by automating high-traffic zones (like packing or sorting).
Connect picking areas to Longwei conveyor lines for continuous flow.
Add sensors and scanners for real-time product tracking.
Example:
A conveyor moves picked items directly from zones to the packing area. Workers save walking time, and orders flow nonstop.
| Technology | Primary Benefit | Example Application |
|---|---|---|
| Conveyor systems | Reduces travel distance | Longwei modular conveyors |
| Sortation systems | Improves accuracy | Automated sorters |
| AGVs / AMRs | Handles transport | Mobile robot integration |
Data shows what’s really happening inside a warehouse. A good Warehouse Management System (WMS) records every pick, movement, and shipment. Managers can use these insights to spot bottlenecks or underperforming areas.
What to track:
Picking accuracy rate (%)
Average pick time per order
Travel distance per worker
Order fulfillment cycle time
Tip:
Use dashboards to visualize performance and predict trends. Adjust staffing or layout based on real data instead of guesswork.
| Metric | Goal Range | Improvement Action |
|---|---|---|
| Pick accuracy | 99.5%+ | Training + automation |
| Pick rate | 150–250 lines/hour | Route optimization |
| Travel distance | ❤️ miles/shift | Slotting review |
| Order cycle time | <24 hours | Workflow balance |
Warehouses change fast. Products move, people rotate, and demand shifts. Regular audits keep systems in check.
Audit checklist:
Are pick paths still efficient?
Are SKUs slotted based on real demand?
Is inventory data accurate in WMS?
Are conveyors or robots operating at full capacity?
How often:
Weekly: Quick walk-through audits.
Monthly: Equipment and safety checks.
Quarterly: Process and performance reviews.
Regular reviews help catch small problems before they grow into major delays.
People remain the heart of every warehouse. Proper training ensures smooth picking and keeps everyone safe.
Essential training topics:
Correct picking and scanning procedures.
Safe lifting and movement techniques.
Use of automation tools like conveyors or scanners.
Emergency and hazard awareness.
Safety tools that help:
Anti-slip flooring near conveyors.
Safety barriers around moving equipment.
Clear traffic markings for AGVs.
| Focus Area | Training Goal |
|---|---|
| Picking accuracy | Reduce errors |
| Equipment use | Minimize downtime |
| Ergonomics | Prevent injuries |
| Communication | Faster coordination |
Well-trained workers make fewer mistakes and feel more confident using automated tools.
Efficiency isn’t a one-time project — it’s an ongoing process. Lean principles help warehouses cut waste and increase value for customers.
Core ideas:
5S (Sort, Set, Shine, Standardize, Sustain): keep everything organized.
Kaizen: small daily improvements from everyone.
Just-In-Time: restock only when needed to save space.
Example of a Lean improvement cycle:
Identify waste (unnecessary walking, waiting, or rework).
Find the cause.
Implement a small fix.
Measure results and repeat.
| Lean Step | Goal | Warehouse Example |
|---|---|---|
| Sort | Remove clutter | Eliminate unused racks |
| Set | Arrange logically | Group SKUs by demand |
| Shine | Clean regularly | Keep conveyors debris-free |
| Standardize | Use consistent methods | Unified pick lists |

Applying Lean methods keeps operations agile, organized, and continuously improving.
Every warehouse runs differently. Some handle thousands of small e-commerce orders daily, while others move heavy pallets across wide spaces. Picking the right solution depends on understanding how your operation works — and where it can improve.
Choosing the right picking system starts by matching it to your warehouse’s unique profile. Here’s what to think about before making a decision.
The type of products and the number of SKUs influence everything — from picking method to automation level.
Low SKU variety: If orders include large quantities of the same products, methods like batch picking or wave picking work best.
High SKU variety: Use zone picking or cluster picking to handle many small, unique orders efficiently.
Fast-moving SKUs: Store them near packing or conveyor areas to shorten walking distance.
| Order Type | SKU Variety | Best Solution |
|---|---|---|
| High volume, few SKUs | Low | Batch or Wave picking |
| Low volume, many SKUs | High | Zone or Cluster picking |
| Fast-turn products | Mixed | Conveyor-integrated flow |
The bigger and more complex the layout, the more important flow becomes. Smaller warehouses may run well on manual or semi-automated systems, while large ones benefit from conveyors and robotics.
Consider these factors:
Number of picking zones.
Distance between storage, packing, and shipping.
Vertical storage (multi-level operations).
Aisle width and worker movement.
Example:
A small regional warehouse might use handheld scanners and batch carts. A national distribution center could use Longwei’s automated conveyor systems to handle continuous, multi-zone picking.
| Warehouse Size | Typical Complexity | Recommended Approach |
|---|---|---|
| Small (under 5,000 m²) | Simple | Manual or batch picking |
| Medium (5,000–15,000 m²) | Moderate | Semi-automated conveyors |
| Large (15,000+ m²) | High | Automated conveyors + robotics |
Cost matters, but so does future growth. Investing in scalable solutions prevents constant upgrades as your business expands.
Tips for budgeting smartly:
Start with modular systems you can expand over time.
Focus on ROI, not just purchase price — faster order processing pays back quickly.
Choose vendors offering customization, like Longwei’s flexible modular conveyor systems.
| Budget Range | Best Fit System | Expansion Potential |
|---|---|---|
| Low | Manual / gravity conveyor | Limited |
| Medium | Semi-automated picking | Moderate |
| High | Fully automated conveyor + robotics | High |
Before investing in automation, assess how ready your facility is. Automation works best when data, layout, and processes are already efficient.
Check these areas:
WMS or ERP system in place?
Consistent inventory labeling and tracking?
Staff trained on tech systems?
Enough floor space for conveyors or robot paths?
Pro tip:
If your operations rely on real-time data and structured workflows, you’re ready to integrate automation like Longwei’s automated sorting and conveyor systems.
Both conveyors and robots improve efficiency, but they shine in different environments.
| Criteria | Conveyor-Based Systems | Mobile Robotics (AGVs/AMRs) |
|---|---|---|
| Best for | High-volume, continuous flow | Flexible, dynamic layouts |
| Movement type | Fixed routes | Free-moving paths |
| Setup cost | Higher initial investment | Lower upfront cost |
| Scalability | Expandable in modules | Easy to redeploy |
| Ideal environment | Large, stable facilities | Variable or small spaces |
| Example solution | Longwei’s Logistics Sorting Conveyor Line | Robot-integrated sorting system |
Rule of thumb:
Use conveyors for steady, high-volume throughput and automated sorting.
Use mobile robots for flexible, changing layouts or low-to-medium volumes.
Combine both for a hybrid system — conveyors for main flow, robots for zone transfers.
Choosing the right picking solution means aligning technology, layout, and goals. When systems fit your workflow, picking becomes faster, smarter, and far more efficient.
Warehouses are evolving fast. New technology, smarter machines, and data-driven tools are changing how we move, pick, and ship products. The next wave of innovation focuses on flexibility, intelligence, and sustainability — helping warehouses work faster while using fewer resources.
Robots aren’t replacing people — they’re teaming up. Collaborative robots (cobots) now work safely beside humans, handling repetitive or heavy lifting while workers focus on tasks that need precision or decision-making.
What this looks like:
Cobots deliver totes or bins to pickers.
Robotic arms handle small item picking from shelves.
Human workers oversee complex or mixed orders.
Why it matters:
Cuts human fatigue by up to 60%.
Boosts pick rates without adding headcount.
Flexible — cobots can move to different zones as needed.
| Type | Task | Benefit |
|---|---|---|
| Stationary robot arms | Item picking | High precision |
| Mobile cobots | Bin transport | Reduces walking |
| Sorting robots | Item routing | Continuous operation |
Artificial Intelligence is making warehouses smarter. Instead of reacting to orders, AI predicts what customers will buy next. It analyzes historical data, sales trends, and even seasonal patterns to prepare inventory before demand peaks.
What it can do:
Suggest optimal SKU placement.
Predict picking volumes for upcoming days or weeks.
Assign pickers or robots dynamically based on workload forecasts.
Example:
An AI system may notice a spike in sports gear sales before summer and automatically re-slot fast-moving items near conveyors for faster fulfillment.
| AI Function | Operational Impact |
|---|---|
| Demand prediction | Reduces stockouts |
| Route optimization | Shorter pick paths |
| Task assignment | Balanced workloads |
Conveyors are no longer just belts that move boxes — they’re becoming intelligent systems powered by IoT (Internet of Things).
Smart conveyor features:
Sensors track product position and condition.
RFID and barcode scanners verify SKUs instantly.
Data flows directly to WMS for live inventory updates.
How it helps:
Real-time visibility of every item on the line.
Predictive maintenance alerts before breakdowns.
Seamless integration between robots, conveyors, and sorting stations.
Example:
Longwei’s modern conveyor systems already use smart sensors for auto-sorting and load balancing, creating continuous flow across different warehouse zones.
| IoT Feature | Function | Result |
|---|---|---|
| Load sensors | Detect weight and movement | Prevent jams |
| RFID tracking | Real-time item ID | Instant verification |
| System analytics | Predict wear | Reduce downtime |
A digital twin is a virtual copy of the real warehouse. It mirrors every movement — from conveyors to robots — and uses data to simulate operations in real time.
Why it’s powerful:
Managers can test new layouts without stopping production.
Systems predict the outcome of process changes instantly.
It identifies inefficiencies before they cause delays.

By integrating Longwei’s intelligent conveyor systems, warehouses gain not just automation — but a complete, optimized workflow from picking to delivery.
A: For most e-commerce operations, batch picking and zone picking are the most efficient. Batch picking lets workers collect items for multiple orders in one trip, reducing travel time. Zone picking divides the warehouse into sections, so each picker focuses on a specific area, which improves speed and accuracy. Many modern fulfillment centers also use cluster picking combined with conveyors or AMRs to handle high order volumes more efficiently. The key is matching the method to order size, SKU variety, and warehouse layout.
A: Conveyors boost productivity by keeping items moving without interruptions. They reduce walking distance, limit manual lifting, and maintain a steady product flow between picking, packing, and shipping. When integrated with barcode scanners or sorting machines, conveyors also increase accuracy and reduce handling errors. Studies show that conveyor systems can cut travel time by up to 60% and improve overall throughput by 30–50% compared to manual workflows.
A: Yes. Modular conveyors are ideal for small and medium-sized warehouses because they’re flexible, easy to install, and can expand as the business grows. They don’t require large infrastructure changes and can fit tight spaces or irregular layouts. For example, Longwei’s Flexible Modular Conveyor System can be rearranged or extended seasonally to handle peak order periods without major redesigns. It’s a cost-effective step toward automation for smaller facilities.
A: The main difference lies in mobility and flexibility.
Traditional conveyors are fixed systems designed for continuous, high-volume movement along set routes. They’re best for predictable workflows where products flow constantly between stations.
AGVs (Automated Guided Vehicles) are mobile robots that carry goods independently. They follow digital paths and can adapt to layout changes or rerouted traffic.
| Feature | Conveyors | AGVs |
|---|---|---|
| Movement | Fixed route | Mobile, flexible |
| Best for | Continuous high-volume flow | Variable, dynamic layouts |
| Setup cost | Higher upfront | Lower initial |
| Scalability | Modular expansion | Easy redeployment |
Many modern warehouses combine both — conveyors for mainline transport and AGVs for flexible zone transfers.
A: Longwei conveyors are designed for seamless integration with most Warehouse Management Systems (WMS) and ERP platforms. They use open communication protocols, sensors, and data interfaces that let your WMS track items in real time. Integration allows:
Automatic SKU verification through barcode or RFID scanning.
Real-time inventory updates during picking and sorting.
Dynamic routing based on order priority or delivery schedule.
The process usually involves connecting the conveyor’s control software (PLC or SCADA) to your WMS through an API or middleware layer. Longwei’s engineering team can customize the interface to fit your warehouse’s existing infrastructure.
A: Automated conveyors require preventive maintenance to ensure reliability and minimize downtime. Key maintenance tasks include:
Weekly checks: Inspect belts, rollers, and chains for wear or misalignment.
Monthly service: Lubricate moving parts and check sensor calibration.
Quarterly audits: Test control systems, motors, and safety features.
Annual overhaul: Replace worn belts or rollers and perform full system diagnostics.
Using smart monitoring systems, like those in Longwei’s intelligent conveyor solutions, allows predictive maintenance — alerting you before parts fail. This approach extends equipment life and keeps throughput consistent.
The future of warehouse picking depends on how well smart design, automation, and reliable conveyors work together. A well-structured layout keeps products flowing smoothly, while automation tools like scanners, robots, and intelligent conveyors reduce errors and save time. When these systems operate in harmony, warehouses become faster, safer, and far more efficient.
