People expect a lot from ecommerce businesses today. We’re used to two-day shipping—at a minimum—thanks to Amazon. Even mom and pop shops need to improve their ecommerce logistics and fulfillment approaches to keep up.
The problem: warehouses are growing not just in popularity, but in size. The height of distribution centers increased by more than two feet in recent years. The total square footage of warehouses increased from 240,410 square feet in 2016 to 305,000 square feet in 2018.
How do you keep track of stock scattered across a mega-warehouse like that?
A warehouse management system (WMS) helps any size ecommerce business scale its fulfillment operations and take on more orders, faster—all without compromising on delivery speed or order accuracy.
This guide shares the benefits of using a WMS, guidance on choosing the right one, and four potential options to choose from.

What is a warehouse management system?
A warehouse management system is software built to support and optimize warehouse and distribution operations. Retailers use this automated technology to make planning, organizing, staffing, and controlling available resources across the supply chain easier.
Every merchant—from ecommerce-only to a brick-and-mortar hybrid—needs a warehouse management system to keep track of fulfillment operations. With one, you’ll be able to handle:
- Returns. Turn what’s often referred to as a logistical nightmare into a streamlined, mostly automated process. Determine which items are damaged, need relabelling, or are ready to go back on the shelf. That data will be visible inside your WMS.
- Warehouse logistics. Instead of written processes that warehouse staff need to remember, they can follow predetermined workflows inside your WMS to improve consistency.
- Integrations. Most WMS platforms integrate with other tools you’re already using, such as shipping solutions and your ecommerce site. With this functionality, there’s no manual back-and-forth data feeding (which is likely causing inaccuracies).
- Reporting and forecasting. When will stock pass its sell-by date? Which bestsellers do you need a constant flow of inventory for? See all of that inside your WMS so you never have out-of-stock messages turning away potential customers.
To summarize: WMS software acts as a central place for your operational processes in a warehouse or distribution center. It provides full visibility into your inventory levels and storage, staff productivity, demand forecasting, and retail fulfillment to improve return on investment.
Components of a good warehouse management system
A WMS has several key features, including many of the following:
- Warehouse design systems, allowing you to set up the most efficient workflows.
- Integration with inventory devices like radio-frequency identification (RFID) and bar-coding technologies.
- Back-office integration with order entry, inventory control, and purchase order modules.
- Real-time inventory tracking so you’re always up-to-date with stock movements.
- Workforce management to help you allocate labor and monitor performance.
- Support for multiple picking and packing methods and overviews of picking zones.
- Compliance labeling and advanced shipping notices (ASNs) so you can manage the arrival of new inventory and keep things up to code.
- Yard and dock management to help delivery partners find the right place to load and unload.
And in terms of usability, the system might also offer:
- Scaling with your enterprise resource planning (ERP) system, if you’re a medium or large enterprise needing everything integrated.
- Advanced reporting capabilities, giving you detailed analytics on what’s happening that you can share with the rest of the business.
- Mobile-friendly design, so you’re not chained to a desk when using it.
Some are more extensive, and some are leaner. There are different options depending on your needs. We’ll go through them below.

Benefits of warehouse management systems
Improve inventory accuracy
Managing inventory is one of the trickiest things about running a retail operation. Too much stock could pass its sell-by date; too little stock and “product unavailable” messages drive potential customers away.
Inventory shrinkage happens when you have less physical stock than your accounting sheets show. It costs businesses about $61.7 billion per year.
WMS software uncovers exactly how much inventory is stored, in real time. You’ll scan bar codes of new inventory and the retrieval of each unit picked in an order. This helps prevent inventory shrinkage.
Warehouse management systems also provide advanced order analytics so you can:
- Understand which states you ship to most
- See which orders haven’t been delivered
- See inventory on hand
- Check historical stock levels at any time
- See how many days left until a SKU is out of stock
- Handle order replenishment based on stock availability
- Manage order allocation to international warehouses or distributors
- Understand average cart values and shipping costs
- Determine where you can save on shipping
Long gone is the era of five-day shipping. The rise of Amazon means customers expect to get their orders fast.
So, what does fast look like? The vast majority (97%) of consumers consider same-day shipping fast, while 95% consider next-day fast. Either way, one thing is clear: items need to turn up at your customers’ doorsteps within 24 hours to be considered gold standard.
Want to offer two-day shipping or less? A WMS can determine shipping times with precision. Customers see accurate shipping estimates for their home address, with no awkward, “Hey, your order is running late because you’re further away than usual” emails necessary.
Plus, most providers have relationships with third-party logistics providers. You can lean on their high order volumes to promise customers fast, free delivery anywhere.

Improve order efficiency
A warehouse management system integrates directly with your ecommerce platform so you can keep stock updated. No worrying about customers placing an order for out-of-stock items. Fewer errors around inventory equals faster fulfillment times and greater accuracy.
This has a domino effect on inventory costs, too. Reducing stockouts and overstocks can lower inventory costs by as much as 10%.
Other WMS software use cases to improve order efficiency and accuracy include:
- Assign pickers optimized routes
- Open additional fulfillment centers to cut down on shipping times
- Improve packing processes
Lower labor costs
A WMS might seem expensive, but productivity gains make up for the price tag. The cost of labor for recounting inventory or repackaging products is less with a WMS. You have a mostly automated system to handle it for you, freeing up time for staff to complete other tasks.
Plus, the warehouse operates more efficiently when order counts are accurate and orders are packed and shipped effectively. There’s less chance of returns eating into revenue. Plus, since order accuracy is higher, you’ll improve customer satisfaction. That makes a WMS system more cost-effective than labor management.
Types of warehouse management systems
Standalone WMS are usually on-premise systems deployed on an organization’s native network. They’re used only for warehouse management features. It’s the most affordable type of WMS but lacks many of the features from an integrated software solution.
They can be combined with existing solutions, but they’re sold as a one-off product without any other supply chain functions.
Standard features include:
- Bar code scanning
- Cycle counting
- Expiration date tracking
- Order picking
The biggest benefit of using a standalone WMS is that you’re in complete control of inventory.
However, a standalone WMS doesn’t cover other types of supply chain operations. Other systems will offer transportation management functions, such as integration with shipment tracking systems with major carriers.
It’s the most basic type of warehouse management system. It’s a good solution for small businesses or those who don’t have much software budget. They can also be used as inventory management systems for SMBs.
Integrated with ERP
One of the most powerful ways to improve ecommerce logistics is by combining your WMS with other tools. It’s a good option for businesses looking to upgrade their software to a larger scale. It can help organizations gain a competitive edge and improve ROI.
Enterprise resource planning is software used to manage an organization’s resources. It gives you a view of all software applications, such as human resources, sales and marketing, finance and accounting, tracking inventory, and CRM.
Some ERP vendors, like SAP and Oracle, offer WMS modules built into their systems.
It’s more expensive, but an ERP can replace all existing software and centralize logistics into one interface. If you don’t like your existing software and want to bring them into one system, you can do so with ERP software.
This type of WMS is different from standalone because it provides warehouse management along with more broad capabilities. Decide if you want to invest in a special WMS or if you’d benefit from an ERP system. It depends on your business’s needs, size, goals, and existing toolstack.
Supply chain management modules
Supply chain management (SCM) software is much broader than integrated or standalone. It typically comes in the form of a supply chain management system, with a subset for warehouse management. It’s used to manage various aspects of the supply chain in one place.
Similar to a standalone WMS, you’ll get an overview of how your warehouse functions. However, the main difference with SCM is that you can manage your entire supply chain in one tool.
The goal is to automate inventory management, product cycles, sourcing of materials, and other common warehousing tasks. It can also assess risks and manage vendor relationships.
With its extra features and scalability, it’ll come as no surprise to hear that this type of WMS can be expensive. You’ll need to consider the costs of installation and maintenance. And, if you’re using a SaaS solution, you’ll also need to consider how the software integrates with your existing system.
To use an SCM as a WMS system, your business will have to invest and integrate new software.
How to choose a warehouse management system
If you’re finding your warehouse isn’t as productive as you would like it to be, here’s how to choose a WMS solution.
1. Evaluate your current system
Adding a new technology to your warehouse processes won’t solve all your problems.
Instead, look at what changes need to be made in your current system. What’s working? What isn’t? How are inaccuracies negatively affecting your organization? You’ll use this information to decide on a WMS.
Ask team members what they find frustrating about the job. Zero in on redundancies and inefficiencies to see where you need to improve.
For example, is your picking being done effectively? If not, you’re wasting time and money. A WMS can help by adding automated retrieval and picking solutions, like optimized pick routes and automated inventory management.
Similarly, manually entering product information for returned products—such as customer, SKU, and purchase price—is a time suck. With a WMS, you can use RFID tags to scan the bar code of a product, update stock levels, and process the refund within seconds.
2. Collect team needs
Once you’ve audited your system, have each team member create a list of functions they feel the warehouse management solution needs. This could be a back-office integration with order entry and inventory control modules, or automations for compliance labeling and ASNs.
Encourage team members to prioritize by need-to-haves and nice-to-haves. This will help you quickly eliminate any WMS that doesn’t meet your team’s or business’s needs.
Get started with these questions:
- What do you need to accurately pick, pack, and ship orders?
- What current workflows could be automated?
- What does your existing ERP system look like?
- What information do you need to make strategic warehousing decisions?
- How fast does warehouse data need to sync across the enterprise?
3. Find and evaluate vendors
Understanding the need-to-haves of a new WMS system gives you a checklist for vetting potential vendors.
But regardless of the individual features the new software needs, an important part of choosing a WMS is the amount of time and effort you’ll need to put into implementing it.
Each vendor should have knowledge of supply chain operations. That includes warehouse management, inventory management, order management, accounting, and integration with EDI.
Once you’ve made a shortlist of potential vendors that check those boxes, look for a solution that improves inventory control and staff productivity. Be sure your warehouse staff can integrate the new system with the tools and equipment at their disposal, such as RFID, communications equipment, shipping systems, pallets, lift trucks, and forklifts.
Next, all information gathered by using this equipment should be made available to your entire enterprise—especially the accounting and inventory management data.
The vendor you choose should be dedicated to serving the changing needs of the warehousing and logistics industry and be committed to upgrading and improving the product.
Finally, think about costs. There isn’t much sense in investing in a new WMS software if you’re not making a return on that investment. Get a full understanding of the operating costs with each option by asking questions like:
- What are the estimated license costs for your implementation?
- What are the estimated build-out costs to adapt the system to your requirements?
- What’s the timeframe and cost for implementation?
- How much should I budget for annual support and maintenance costs?
- How much should I budget for staff training costs?
It’s also worth asking if the WMS vendor has case studies of how other companies of a similar size/industry successfully used the software. Look for data such as:
- Time saved per hour
- Improvements in order accuracy
- Percentage reduction in errors
- Dollars saved or recovered
- Increase in order processing speed or throughput
By this point, you’ve got a shortlist of WMS vendors to choose from. Now comes the fun part: choosing which one you’ll use in your warehouse.
There is no best practice here. To summarize, the right WMS for you fits within your budget and has proven case studies to show how it’s solved problems for other companies. It should also integrate with the tools and technologies you’re already using.
The ideal WMS includes the need-to-have features your team listed (and a few nice-to-haves, too). The final cherry on top is a WMS vendor that has the training materials you need to train warehouse staff on how to use the software.
Once you’ve chosen, start integrating the WMS with your existing setup. Elliott Davidson, an ecommerce consultant at Parcel Master, advises the following:
- Run a logical labeling system for your bin locations, like zone, row, rack, shelf, and tote.
- Don’t put all one brand’s products in one location. The odds of picking the wrong color or size, even a slightly different product, are a lot higher.
- Your bestselling items should be on the closest racks to the packing benches to reduce how far the pickers have to walk to process orders.
- Run a bar code scanner so you can have multiple quality assurance checks to make sure you’re picking and packing the correct products to reduce errors.
Find (or upgrade) your warehouse management system
There’s no doubt a WMS has its benefits. With the right software, you’ll improve order and inventory accuracy, streamline logistics, and lower manual labor costs. That’s bound to have an impact on your bottom line.
Whether your goal is to automate your warehouse operations for the first time or upgrade your existing system, the above guide will help you find one that suits your business needs.
