How to choose the best warehouse management system (WMS)
Choosing the best warehouse management system (WMS) is a key step toward improving logistics performance and responding quickly to business needs. A WMS must address a company’s current requirements while also evolving as the organization grows. To make the right choice, businesses should assess factors such as the software’s functionality, integration capabilities, scalability, deployment model, and the provider’s expertise.
This article outlines the main criteria to consider when selecting a system that fits your facility’s characteristics and objectives.
1. Start with your warehouse
No two facilities are alike, so a WMS must be able to adapt to the specific characteristics of each one.
According to a study published in the journal Systems, WMS selection should be based on a comprehensive analysis of warehouse operations. Factors to consider include the warehouse layout, number of SKUs, order type and frequency, level of automation, ERP (enterprise resource planning) integration requirements, product characteristics, and the company’s technology infrastructure.
It’s also important to identify the main problems affecting current operations, such as picking errors, delays, inventory discrepancies, or bottlenecks. Tracking these metrics allows companies to assess the impact of implementing a WMS later on.
2. Define what the WMS actually needs to do
Once you’ve analyzed your warehouse, the next step is to define the functional requirements the software must deliver. Although many WMS platforms share core features, each company has different needs based on its operations and growth plans.
Essential WMS requirements
Every WMS coordinates daily warehouse operations and incorporates capabilities for receiving goods, assigning storage locations, controlling stock, and picking and shipping orders. These tools form the foundation for streamlining logistics flows and maintaining product traceability.
Businesses should also assess how the solution supports day-to-day operations. A WMS should be configurable enough to adapt to most processes. If your company has highly specific requirements, the platform should also support customizations that address those needs.
Finally, usability plays a central role. An intuitive interface designed for the device being used makes employee training easier. Dashboards and real-time performance indicators also facilitate faster decision-making.
Industry-specific requirements
Certain industries and regulatory requirements call for specialized functionality. Businesses should therefore verify that the WMS can address these needs without relying on complex software development.
For example, food and beverage companies need features such as lot management, expiration-date tracking, and FEFO (first expired, first out) shipping strategies. In the pharmaceutical industry, complete traceability and compliance with regulatory requirements are critical. Third-party logistics (3PL) providers, meanwhile, often need to manage multiple clients and bill for their services. Cold storage facilities are charged with monitoring temperature conditions throughout the warehousing process to safeguard product quality.
3PL providers are a good example of how the same WMS must meet the requirements of different industries. OnRoute, for instance, implemented Mecalux’s Easy WMS warehouse management system in its three facilities to strengthen product traceability and expand its ability to serve companies across different sectors. “We were looking for a digital tool that could support our growth. By adding traceability features and making it easier to uniquely identify every item, we can adapt to industries that require tighter product control, such as pharmaceuticals and cosmetics,” says the company. Thanks to this digital transformation, OnRoute has achieved inventory accuracy of nearly 99%.
Current requirements vs. future requirements
A WMS must be ready to adapt as your business evolves. When defining the solution’s requirements, consider potential changes such as an increase in order volume, the opening of new facilities, the introduction of automation, or expansion into new sales channels.
3. Assess how the WMS will integrate with your operation
A warehouse is part of an ecosystem that includes multiple applications and technologies. The WMS must exchange information with your ERP and transportation management system (TMS) to synchronize processes such as order processing, inventory control, and shipping.
For companies that sell through digital channels, the WMS integrates with ecommerce platforms to keep inventory information up to date and speed up order fulfillment.
In automated facilities, the WMS must be able to integrate with the solutions responsible for coordinating processes, such as a warehouse execution system (WES) and warehouse control system (WCS). It should also be ready to support the addition of new equipment, such as autonomous mobile robots (AMRs), as your organization evolves.
4. Check whether the WMS can grow with the business
Warehouses are constantly adapting to accommodate new products and changing customer needs. For this reason, it’s crucial to verify that the WMS can grow at the same pace as the business and respond to new scenarios without compromising operational throughput.
Before making a decision, ask the provider for performance tests or relevant case studies showing how the WMS responds under different conditions. For example, you could evaluate its behavior when order volume increases, new storage systems or warehouses are added, automation is implemented, or the company expands internationally.
NEXECOM, a French online retailer of home goods, is one example of this ability to scale. The company installed Easy WMS to support its expansion plans and gain a solution that would grow with the business. Thanks to the software’s modular architecture, NEXECOM has added specific modules for ecommerce, multi-carrier shipping, and analytics. “A fast-growing ecommerce company needs to modernize its warehouse roughly every two or three years to keep up with market changes,” says the retailer. NEXECOM expects to double its revenue in the coming years, which will increase its workload. Easy WMS’s modular architecture will allow the business to add new capabilities as its logistics needs change.
5. Review WMS deployment and implementation options
Implementing a WMS is a project that requires planning and coordination between the client and the software provider. Before making a decision, consider factors such as the deployment model (SaaS or on-premises), implementation strategy, data migration plan, user training, and support after go-live.
Although each provider follows its own methodology, implementation typically includes the following phases:
- Project kickoff. The client and provider define the objectives, scope, and schedule.
- Solution development. The WMS is adapted to warehouse processes, taking into account different operating scenarios.
- System configuration. WMS capabilities are configured and validated before deployment.
- Go-live. The provider supports the client to ensure that the system operates correctly as warehouse activities begin.
It’s also advisable to check how the solution will be validated before final deployment. Some providers offer customized demonstrations, pilot tests, or simulations using digital twins to minimize risk and confirm that the WMS meets the warehouse’s needs.
6. Calculate the true cost of the WMS
Implementing a WMS should be viewed as an investment designed to improve warehouse efficiency. Before comparing different solutions, identify both the project costs and the benefits expected over the medium and long term.
The budget may include the selected deployment option, the number of licenses, hardware, and services such as technical support. Once the cost has been estimated, you can calculate the expected return on investment (ROI) using metrics such as order cycle time, picking error rates, inventory accuracy, labor productivity, and the time saved on administrative tasks.
7. Evaluate the WMS provider, not just the software
A good solution should be backed by a provider that can support the company beyond implementation. Factors such as industry experience, international presence, investment in R D, and the product roadmap are all worth considering.
Ervin Germany, a manufacturer of metallic abrasives for industrial treatments, took these criteria into account when selecting its warehouse management system. The company implemented Easy WMS in two of its facilities to strengthen inventory control. “A few years ago, we defined our digitalization roadmap to gain operational visibility, improve efficiency, and advance sustainability. A WMS is a key part of this strategy,” says Ervin Germany. “We chose Mecalux because it offered a scalable, international solution that met our requirements.”
8. Questions to ask a WMS vendor before making your decision
Before selecting a warehouse management system, ask the vendor a few key questions. This will help you compare your options and find the best fit for your company.
- Can the WMS integrate with our ERP?
- How does the WMS integrate with my automated systems?
- Which features can be configured, and which require custom development?
- How long does WMS implementation typically take?
- Which implementation costs aren't included in the license?
- How are software updates handled?
- Can the WMS support multiple warehouses?
- What happens if our order volume doubles?
- What support is available after go-live?
- Can we speak to customers with similar operations?
Choosing the best WMS for your warehouse
WMS selection involves much more than comparing features or prices. The right solution will address your warehouse’s current needs, integrate with the rest of your systems, and adapt as your business grows. A thorough evaluation will make it easier to choose a system that delivers long-term value.
