A warehouse management system (WMS) is a piece of software which automates key warehouse processes. A WMS uses barcodes and radio frequency (RF) handheld terminals and other mobile devices to direct and track the movements of products and people within the warehouse, providing a real-time picture of all activities.
The system also generates all the tasks which must be performed at each stage in the warehouse process. These instructions are delivered to staff and confirmed back to the system via the handheld terminals. Every warehouse is unique and comes with its own challenges. A flexible, real-time WMS can cater to almost any scenario.

When receiving products, paper lists, such as delivery notes, are commonly used to reconcile actual deliveries with expected receipts. With a warehouse management system, operators inspect and record receipts on a mobile handheld terminal, scanning barcodes where available to enhance accuracy. The WMS then automatically reconciles these against purchase order information in the system and either confirms that the delivery is correct or flags any discrepancies.
If you have multiple purchase orders with the same supplier, the system can create a consignment that allows operators to receive against all purchase orders (typically the oldest first) and streamline the goods-in process without losing traceability.
Put-away falls into two core types - either putting away pallet to bulk storage or smaller amounts of individual SKUs into picking locations. Many warehouses need their goods to be picked from anywhere, while larger operations may use bulk storage and specified pick faces. A warehouse management system can enhance both of these put-away setups. A series of simple and easy to follow instructions are issued to warehouse staff via the handheld device. This requires little to no training to use and reduces the chance that operators will make a mistake.
In addition to managing your inventory, a warehouse management system will also control and allocate your resources in the most efficient way. As soon as a task is completed, the system will look for the next priority task that an operator is authorized to do and will assign it to them automatically.
When it comes to inventory management, warehouses have little room for error. The inventory function is where all of the products handled by the warehouse are defined to the system. These product attributes are then used by the warehouse management system's rules engine to drive the agreed operational processes, for everything from receiving and putting away to storage location (for example, no liquids stored over solids), and finally, to picking and dispatch criteria.
One of the most useful features of a WMS is pick-face replenishment. It can be frustrating for pickers if the stock isn't in the right place at the right time. A real-time task management system will detect that a location has reached an agreed minimum and create a task to top up the location and will make this task a priority if an order is waiting. You can also interrogate the warehouse management system to show you stock information at a summary level and in detail.
Order fulfillment comes in all shapes and sizes, from full pallet picking through to case and item picking, from a wide variety of locations. A best-of-breed WMS will cater for all of these within a single operation if required. A key efficiency gain is the ability to pick more than one order in a single walk, or even better, the ability to use an autonomous mobile robot (AMR) for more advanced and efficient cellular picking.
A real-time system will also take into account next-day orders so these can automatically be assigned to a pick walk as soon as they are received. Each picking routine will be carefully designed to cater for the smallest, largest, and average order size required by your operation, ensuring the optimal pick sequence and path for every order or batch of orders.
Depending on your specific business, the relative order size and the amount of items that are barcoded will affect how orders are packed. In the example of an e-commerce company, orders are scanned to verify accuracy and that the correct dispatch box is selected. Labels and dispatch notes are automatically generated and can be configured to meet your specific requirements.
Most warehouse management systems integrate directly with a range of parcel carriers, such as FedEx and USPS, and also carrier management systems, such as RateLinx or Shippo. These integrations will not only generate the correct labels for each carrier and service type, but will also automatically generate export paperwork and end-of-the-day files where required. Some warehouse management systems also support the same process, but in reverse, for the effective management of returned items.
Quickly identifying problem orders, locations, or inefficient operatives could save you time and money. Advanced warehouse management systems can provide an at-a-glance picture of warehouse performance against key performance indicators, supporting data-driven decision making in real time. Some also provide access to historical data, allowing you to accurately forecast resourcing requirements, monitor performance over time, and identify areas for improvement.
Warehouse management systems with more powerful reporting capabilities can also manipulate and blend stored information and client data across various sources into one cloud-based central dashboard. This gives your business the ability to make the best decisions from an amalgamation of key metrics.
Successfully managing the logistics operations of a growing e-commerce business is no easy task, no matter how you're going about it. However, in the rush to fulfill orders, refund returns and keep shelves stocked, you may be falling behind your true potential.
Many businesses use a warehouse management system to keep track of orders and stay on top of inventory planning, among many other essential logistics tasks. The WMS may take the form of an on-premises software solution or perhaps even a large spreadsheet or even a paper filing system developed through trial and error. While these methods may get the job done, it can be hard to realize the efficiency and control you could be missing out on by neglecting to update this key part of your supply chain.
Whether you're just getting by or are already considering making a switch, here are a few key signs that it's time to upgrade to the next generation of warehouse management systems:
- Business is Booming
- Accepting the Status Quo for Too Long
- Still Using Spreadsheets
- Going Global
In a business world full of buzzwords and marketing schemes, no piece of technology has been more discussed, yet more misunderstood, than "the cloud."
At its core, the cloud is simply a changing of location with respect to where software is hosted. In the past, most companies needed to install software such as a WMS on their own servers, often a time consuming and costly exercise. Now, through cloud computing, software vendors use off-site servers to deliver services through the internet. In theory, this provides a number of benefits to the end user, including:
- Lower capital costs
- More space
- Quick and easy deployment
- Flexibility
Properly understanding when, how and to what extent a warehouse management system will contribute to process efficiencies and costs savings is key to making the right decision for your business. There are four steps involved in establishing credit ROI calculations and estimates to build your case for a new WMS.
- Collect and understand all current costs
- Articulate a value statement for each cost compound
- Understand your processes
- Accept help from your vendor, but perform calculations independently
Investing in a warehouse management system (WMS) is a big decision: defining requirements, evaluating vendors, negotiating terms, implementation and stabilization are all discrete and complex activities. they take time and are usually performed in addition to other responsibilities. So, when does it make sense to go through that effort?
There are three aspects of your company and warehouse's growth that should pique your interest in improving your current WMS technology:
- Strategic Plans
- Compelling Events
- Warehouse Operations
You've selected a vendor, agreed on pricing and timing, and now you're getting ready to kick off one of the most disruptive, risky and complex tasks in a warehouse. Sounds fun, right? Not really - but there are a few practices that, even if you've never implemented a new warehouse management system before, will increase the likelihood of success:
- Prepare your organization.
- Stay aligned with your vendor.
- Remove obstacles.
