What is a Pick List? Beginners Guide on How to Use It

Orders coming in fast is a good problem—until fulfillment turns into a scramble.

When team members are second-guessing item locations, grabbing the wrong products, or missing pieces entirely, it’s a sign your process needs structure.

That’s where a pick list comes in.

It brings clarity to chaos, making sure your team knows exactly what to grab and where to find it.

In this guide, we’ll break down what a pick list is, how it works, and how to build a system that helps you stay fast, accurate, and scalable.

What is a Pick List?

A pick list is a document or digital file used in warehouses and fulfillment centers to guide staff in collecting the right items for an order.

It details what to pick, how many, and where to find them within the storage area—making it an essential part of the order fulfillment process.

Think of it as a shopping list… but for your warehouse team.

The clearer and more organized the pick list, the faster and more accurately your team can work.

What are the Benefits of Having a Pick List?

A pick list keeps your warehouse team focused, organized, and efficient. Here’s how it helps improve day-to-day operations:

Improves Picking Accuracy

With clear product names, quantities, and locations, pickers are less likely to grab the wrong item or miss one entirely.

Speeds Up Fulfillment

Well-structured pick lists reduce second-guessing and minimize the time spent walking around the warehouse.

Reduces Training Time

New staff can get up to speed faster when instructions are laid out clearly and consistently.

What is Included in a Pick List?

A pick list contains all the essential details a warehouse picker needs to retrieve the correct items quickly and accurately.

• Order number – used to track and identify the order
• Product name or SKU – ensures the right item is picked
• Quantity – shows how many units to retrieve
• Storage location – indicates where the item is stored (aisle, bin, or shelf)
• Special instructions – notes like “fragile” or “cold storage” when applicable
• Barcode or QR code – optional, but useful for scanning and reducing errors

Including this information helps your team avoid confusion and keeps the fulfillment process moving smoothly.

Different Types of Pick Lists and Picking Strategies

Not all pick lists are used the same way. Depending on your warehouse size, order volume, and setup, different picking strategies can help improve speed and accuracy.

Below are the most common types:

Discrete (Single Order) Picking

Pickers handle one order at a time from start to finish. This method is simple and accurate, best for low order volumes or high-value products.

Batch Picking

Multiple orders are grouped together, and shared items are picked in one go. This reduces walking time and is ideal for high-volume, small-item fulfillment.

Zone Picking

The warehouse is divided into zones. Each picker is assigned to one zone and only picks items within it. Orders are later consolidated before packing.

Wave Picking

Orders are released in scheduled “waves” based on criteria like shipping time, carrier, or order type. It’s useful for coordinating fulfillment with outbound logistics.

Cluster Picking

Multiple orders are picked at the same time, with items sorted into separate bins or totes as the picker moves through the warehouse.

This improves efficiency while keeping orders organized.

How to Create a Pick List System That Actually Works

Creating a functional pick list system isn’t just about listing items—it’s about building a repeatable process that improves accuracy, speeds up fulfillment, and scales with your operations.

Below are key steps to help you set up a system that actually delivers results.

Choose the Right Picking Method for Your Workflow

Before building your pick list, define your picking strategy.

Are you handling high volumes with repetitive SKUs? Batch or cluster picking might fit. Is your inventory spread across multiple zones? Go with zone picking.

Your pick list should match the flow of your warehouse and the volume of orders you process daily.

For example, a discrete picking system may work for a small store, while wave picking benefits time-sensitive operations with cutoff shipping windows.

Map Out and Organize Your Warehouse Layout

A disorganized warehouse will limit the effectiveness of any pick list.

Make sure every product has a clearly labeled bin, shelf, or rack location. Use consistent identifiers for these locations (e.g., A1-3 for Aisle 1, Shelf 3).

Your pick lists should reflect this layout, guiding pickers from one section to the next in the most efficient path possible.

A well-mapped route minimizes travel time and reduces confusion.

Use a Digital System to Generate Pick Lists Automatically

Avoid manual entry.

Use a warehouse management system (WMS), order management platform, or eCommerce backend that supports pick list generation.

Digital systems pull orders in real-time and automatically produce pick lists with product details, SKUs, quantities, and locations.

Look for systems that integrate with your eCommerce platform or ERP.

Bonus if they also support barcode scanning, mobile devices, or real-time syncing with shipping automation—like what Carriyo can offer through post-purchase workflows.

Standardize What Information Goes on Your Pick List

Every pick list should follow a consistent format. This includes:

• Order number
• Customer name (optional, if needed)
• Product name and SKU
• Quantity to pick
• Storage/bin location
• Barcode or scannable code
• Special handling instructions (if any)

Clear formatting reduces misreads and speeds up onboarding for new pickers.

Train Your Staff on the System, Not Just the Tools

Even with automation, human error can still happen. Train pickers on how to read pick lists, follow optimal picking paths, and double-check accuracy.

Create mock orders or walkthroughs with new hires so they get hands-on practice in real scenarios.

Training isn’t just about tech—it's about building habits around accuracy and efficiency.

Validate and Scan During Picking

Use barcode scanners or mobile apps to validate items during picking.

This step helps catch errors early before items are packed and shipped.

Digital validation also allows your system to update inventory in real time, giving you accurate stock levels across all channels.

Monitor KPIs and Improve the Process

Once your system is live, track key performance indicators like:

• Pick accuracy rate
• Items picked per hour
• Average fulfillment time
• Return rates due to incorrect items

Use these insights to fine-tune your pick list design, warehouse layout, or picker training. Small adjustments can lead to major efficiency gains over time.

Keep It Flexible and Scalable

As your business grows, your pick list system should evolve.

Be ready to support new picking strategies, seasonal spikes, or warehouse expansions.

Choose tools and workflows that can scale without needing a full overhaul every time you grow.

FAQs

What’s the difference between a pick list and a packing slip?

A pick list is used internally to collect items from inventory, while a packing slip is included in the shipment to show the customer what’s inside their order.

Can pick lists be used in small businesses or manual setups?

Yes. Even without a warehouse management system, small teams can create simple pick lists using spreadsheets or printed templates to stay organized and reduce mistakes.

How do pick lists work with barcode scanners?

Each product on the pick list can include a barcode or SKU. As the picker scans each item, the system verifies accuracy in real time and updates inventory levels automatically.

Conclusion

Building a smooth and reliable pick list system takes more than just good formatting—it requires the right tools, the right flow, and the right support behind the scenes.
