• Faster order fulfillment through effectivized picking and packing, real-time management, optimized task management and more will lead to an increase in customer satisfaction.

Types of Warehouse Management Systems

Best of breed (standalone) WMS

Best of breed warehouse management systems are software applications that operate independently to manage and optimize warehouse operations. These systems have logistic processes as their core focus, providing detailed real-time insights that serve to optimize inventory and storage. These solutions support extensive and advanced functionality within the warehouse processes such as inbound handling, put away, pick & pack, stock replenishment and inventory management. They also have a variety of extended capabilities like Value added services, Workforce management, Dangerous goods management and Third party billing etc. The result is that every square meter of the warehouse and its processes are covered and optimized. Best of breed WMS may integrate with other systems, such as Enterprise Resource Planning (ERP) or a Transport Management System (TMS), for broader logistics visibility and coordination.

ERP module

An ERP WMS-module manages warehousing as an integrated part of an ERP system. By being part of a larger ERP system, an ERP-integrated WMS- module can link warehouse functions directly to broader business processes, like purchasing, accounting, and sales. It may be a viable option for organizations with simple or small-scale logistics, where logistics are not at the core of the business. Some downsides to using these integrated modules are that the system still thinks as an ERP, thereby having more focus on financial processes, rather than logistics and stock insights.

Supply chain module

WMS functionality can also be delivered and managed as part of a SCM (supply chain management) system. This type of setup means that warehouse functions are tightly linked to other supply chain components, such as transportation, procurement, demand planning, and inventory management. A shared workflow allows for a comprehensive supply chain overview. However, a supply chain WMS-module may not always offer as many advanced warehousing capabilities as standalone WMS solutions, depending on how they’ve been built. Was the core once to be (for instance) a TMS and was extra WMS-functionality added later on, or was the software built to oversee the whole supply chain? There’s a difference in that. It can be challenging to customize a WMS setup that is a part of a broader SCM system, as updated and new features are tied to the SCM provider.

Cloud-based versus on-premise WMS

The main difference between an on-premise and a cloud-based Warehouse Management System lies in where the system is hosted and how it is accessed. 

An on-premise Warehouse Management System is a software solution installed and operated directly on a company’s own servers and hardware infrastructure. This setup gives businesses full control over their system, data, and security protocols, as the WMS operates independently from external internet connections. It is often preferred by organizations with strict data security and compliance needs, such as those handling sensitive information, as they can customize security and functionality according to specific requirements.

 A cloud-based WMS is hosted on a cloud, being accessible over the internet. Accessing the functionality online instead of having it installed locally makes your business less hardware-dependent. Cloud-based systems provide a new level of flexibility, scalability, and cost-effectiveness compared to on-premise systems. Anywhere, anytime access provides constant real-time visibility, offering superior scalability, real-time visibility, cost efficiency, and seamless integration with other platforms.

In summary, an on-premise WMS provides more control and customization at the cost of higher initial investment and maintenance, while a cloud-based WMS offers flexibility, lower upfront costs, and scalability, managed externally by the vendor. The choice often depends on a company’s size, growth plans, budget, and specific data handling requirements.

The WMS implementation process - step by step

Implementing a WMS software might seem daunting at first. However, the process can be streamlined through good planning and selecting the right vendor. WMS implementation can be divided into four steps:

1. Planning and assessment: outline objectives, requirements, constraints, and anything else relevant to the process. This step should determine business requirements, key stakeholders, costs and budget, implementation team, timeline, actions, and data migration/backup plans. It is also time to find a WMS vendor to deliver the system. Use your business requirements to identify the best possible match.

2. Pre-implementation: account for your warehouse environment and your logistics processes, so the WMS provider gets a detailed overview of your operation. It is also time to decide on what to do with your existing data, and outline integration requirements.

3. Implementation: install or log in to your new WMS. Double-check data flow and data quality to identify errors, migrate data and implement your third-party integrations. The implementation phase also includes staff training.

4. Post-implementation: monitor the system, making necessary adjustments and improvements. Keep tweaking the WMS and gather feedback from your team and the users to continually improve the setup.

WMS hardware requirements

 

A quality WMS software combines the best hardware and software features to effectivize warehouses. Without the right hardware setup, you will have a hard time keeping up with the competition. Mobile devices, printers and labels and automation integration are three examples of essential technologies in the area.

Mobile devices (handheld scanners)

WMS-integrated mobile barcode scanners and RFID readers play a crucial role in optimizing warehouse operations. Both technologies enhance accuracy, speed, and efficiency by automating data capture and minimizing human error in various processes, such as inventory tracking, order picking, and shipping. Using handheld mobile devices helps you to:

• Capture data in real-time

• Scan and move inventory quickly

• Optimize picking and packing

• Improve shipping accuracy

Printers and labels

Compatible label printers are essential for efficient operations, particularly for printing barcodes, shipping labels, and other essential documentation. Having the right label printers ensures that your WMS software can seamlessly generate and print labels that are critical for inventory tracking, order fulfillment, and shipping. The main advantages are:

• High-quality barcodes and consistent barcode standard

• Ensure packages are delivered to the correct destination through error-free on-demand printing with multiple carrier support

• Integrated label printers that work together with a variety of warehouse functions

Warehouse automation integration

Modern WMS systems can be integrated with warehouse automation technologies like robotics, conveyor belts, and AS/RS (automated storage and retrieval systems). These integration capabilities are crucial for modern warehouses, especially those handling large volumes of goods while requiring fast, accurate order fulfillment. The solutions will help you to:

• Automate picking and sorting, find the most efficient routes and synchronize data in real-time

• Automate conveyor system to control the movement of goods based on predefined workflow, optimize item sequencing and reduce misrouting or packing errors

• Use AS/RS technology like cranes, shuttles, or other automated mechanisms to store and retrieve goods from high-density racking systems. The WMS directs these systems by providing them with real-time inventory data, such as which items need to be retrieved for order picking or where new inventory should be stored. This reduces retrieval time and ensures that inventory levels are accurate without interrupting operations.

Challenges of implementing a WMS

Implementing a WMS software comes with challenges, but the transition will be easier if you are aware of them and approach them in the right way.

Cost of implementation

Implementing a WMS requires a significant upfront investment, but the costs can be mitigated by the long-term return on investment (ROI) generated through operational improvements. Costs can be divided into these main categories:

• Software costs: includes licensing or subscription fees, customization, integration, maintenance and support

• Hardware costs: servers, network infrastructure, storage systems, operational expenses, devices and other required technology

• Integration and implementation costs: integration with other platforms, such as ERP, CRM, or MRP (material requirements planning) systems. If the WMS is integrated with automated systems like robotics, conveyors, or AS/RS, the complexity and cost of integration will increase. Many companies also need to hire external consultants to help with system selection, process redesign, and change management.

• Training costs: employees need to be trained in using the new WMS effectively, which incurs both direct costs (for the training itself) and indirect costs (from reduced productivity during the learning curve).

• Change management and downtime costs: implementing a WMS often requires revisiting and redesigning workflows and processes within the warehouse, and there might be initial system downtime and instability. The cost of process adjustments and potential loss of productivity during the transition needs to be taken into account.

Employee resistance

The warehouse workers are a crucial part of the transition, and there might be some resistance to new technology within the business. It is a common challenge, but adequate training and dialogue can help ease the process. These are some important aspects to deal with regarding employee resistance:

• Fear of the unknown and job insecurity: warehouse employees, supervisors, and managers may worry that the WMS will automate tasks they used to perform manually, leading to job reductions or changes in roles. These fears, along with concerns on how they will perform in the new system, can lead to pushback and delayed WMS adoption.

• Disruption of routine and comfort with existing processes: employees who are accustomed to processes may have a sense of security and comfort with established routines. A new WMS forces them out of their comfort zone, which often leads to resistance. They might also resist the transition because they fear making mistakes, which could slow down operations or even result in penalties or corrective actions.

• Perception of increased workload: It is important to communicate the WMS transition properly, as employees might anticipate an increased workload. That could be the case during the transition period, but it is important to clarify that the system is there to make their lives easier.

• Lack of engagement or inclusion in decision-making: if employees aren't involved in the decision-making process for WMS implementation, they may feel the system is being imposed on them without their input. This can result in disengagement and opposition. It is also important to explain how the system will address their needs and provide value in the future.

Data migration

Transferring existing data to a new WMS from a previous system can be a complex and error-prone process. The data migration involves moving critical information about inventory, orders, SKUs, locations, and more from the old system into the new WMS while ensuring that everything remains accurate, up-to-date, and usable. Here are some key challenges involved in the data migration process, as well as strategies to minimize disruption:

• Data incompatibility and formatting: there might be data structure differences, inconsistent data standardization or data export issues hindering the data transfer from the old system to the new WMS software. Review and clean up your data before starting the migration. Identify and resolve any inaccuracies, duplicates, or inconsistencies. Standardize data formats, especially for key fields like SKUs, product names, and locations. This reduces the chance of carrying errors into the new WMS.

• Data quality: incomplete, inaccurate or duplicate data in the legacy system can cause issues during migration. Make sure to address these before they risk causing errors, misplacements, or inefficiencies in the new system.

• Data sets and historical data: in most warehouse systems, data points are interdependent. For example, inventory levels are tied to locations, orders are tied to products and customers, etc. Transferring this interconnected data while maintaining these relationships can be difficult, and deciding what historical data to transfer can be challenging. While some older data might not be relevant for ongoing operations, some of it may be critical for tracking trends, performance analysis, or audits.

• Downtime and operational disruptions: the data migration should cause minimal day-to-day disruption. Run the old and new systems in parallel for a short period to ensure that the WMS works correctly before fully switching over. This allows you to continue operations while the new WMS is being implemented, limiting potential downtime during the migration.

• Post-migration validation: once the data has been migrated, perform a thorough validation to ensure all data is correctly transferred. Compare the new system’s data with the old one to confirm accuracy. This involves checking key records, inventory levels, product details, and orders. Set up a reconciliation process to verify that the transferred data aligns with physical inventory and ongoing operations. This ensures that there are no discrepancies between the WMS data and actual warehouse conditions.

System downtime

We touched upon downtime and disruptions, which is important to address during the transition. Here are some good strategies to minimize operational impact during a WMS implementation:

• Plan the installation during non-peak hours or low activity periods: if downtime is necessary, schedule it during non-peak hours (e.g., overnight or on weekends) to minimize impact on day-to-day operations. Ensure all stakeholders are aware of this schedule to avoid any confusion or delays in order fulfillment.

• Phased or staggered rollout: instead of installing the WMS across the entire warehouse at once, roll it out in phases. For example, start by implementing the WMS in one section of the warehouse or with a subset of workflows (e.g., inbound receiving first, then outbound shipping). Pilot testing, where the system is tested in a small, controlled part of the operation is also a good idea. This allows teams to identify and resolve potential issues in a limited environment before a full-scale rollout, reducing the likelihood of large-scale downtime.

• Conduct extensive pre-installation testing: before going live, test the WMS in a sandbox environment to simulate real-world operations. This helps identify any potential issues with system functionality, data migration, or integration with other platforms (ERP, TMS, etc.). Stress test the setup by simulating high-volume scenarios, ensuring that the new WMS can handle peak loads without crashing or causing delays. This type of testing can reveal performance issues before they cause disruptions during busy periods.

• Create a detailed contingency plan: have contingency plans in place for critical operations that might be affected by downtime. For example, develop manual workflows or alternative tracking methods that can temporarily replace WMS functions in case the installation process runs longer than anticipated. If order fulfillment is delayed, consider offering alternative shipping options to maintain customer satisfaction, such as expedited delivery post-downtime. Engage the WMS vendor’s technical team or IT consultants for support during installation to resolve unexpected issues quickly, keeping downtime to a minimum.

• Communicate clearly with all stakeholders: make sure to tell all relevant stakeholders about the transition. Ensure all teams—warehouse staff, IT, customer service, and management—are aware of the installation timeline, what to expect during downtime, and what backup procedures will be in place. If downtime is expected to cause shipping delays, proactively communicate with customers, providing realistic timelines for order fulfillment. Offering transparency helps manage expectations and mitigate potential dissatisfaction. Maintain close coordination with the WMS vendor to ensure they’re available for troubleshooting or additional support during the go-live period. This partnership is crucial for quickly resolving issues and ensuring a smooth transition.

• Enhanced transparency: having visibility across the whole supply chain is one of the biggest challenges for warehouses around the globe. Blockchain’s decentralized nature allows all participants in the supply chain, including manufacturers, suppliers, logistics providers, and customers, to access and share the same data in real time. Record transactions on blockchain ledgers cannot be altered without the consensus of the network, ensuring that the data is secure and tamper-proof. Provide suppliers, buyers, customers and other participants in the product journey with accurate data that builds trust and improves efficiency.

• Improved traceability: traceability is crucial in many industries, such as food, pharmaceuticals, and luxury goods, where knowing the origin of a product and tracking its movement through the supply chain is essential. Blockchain significantly enhances traceability by creating a digital trail of a product's entire lifecycle. Track products, batches or shipments in real-time, knowing exactly when they change hands in the supply chain. Easily trace contaminated or defective products back to the source, minimizing the scope of recalls and ensuring consumer safety.

• Smart automation: Smart contracts, which are self-executing actions written into code, can automate processes in the supply chain. The contracts are triggered when predefined conditions are met, reducing the need for intermediaries and manual intervention. Smart contracts help you automate payments between supply chain partners. For example, once a shipment arrives and its receipt is confirmed, the blockchain triggers an automatic payment, reducing delays and disputes. The technology can also automate compliance checks and submission of necessary documentation. This can be especially useful for international shipping, where a lot of documentation is required.

• Increased accountability and trust: blockchain increases accountability across the supply chain by ensuring that every action taken by a participant is recorded on an immutable ledger. It makes the supply chain easier to audit and tracks who did what, while also building trust among stakeholders. Blockchain makes it clear who is responsible for each step of the process by recording transactions on an immutable ledger, identifying where issues occur and who is responsible. It also eliminates the need for third-party intermediaries, such as brokers or auditors.

• Fraud prevention and security: blockchain technology ensures that transactions are secure and protected from fraud. Each participant in the blockchain network has a unique cryptographic key, and only authorized entities can add or verify transactions. Once a transaction is added to the blockchain, it cannot be changed or deleted. This immutability reduces the potential for fraud, as no single party can manipulate the data to conceal errors or unethical practices. Encryption ensures that sensitive supply chain information never gets compromised, keeping inventory, shipment and payment data confidential.

As you can see, we are quickly entering an era of AI and robotics, data-led innovation, quick commerce, and sustainable operations. Innovation is constant, and warehouses need to keep up to stay ahead of the competition.

Comparing WMS and ERP systems

Warehouse management systems and ERP systems are both essential tools for managing different aspects of a business, but they serve distinct purposes and are designed to handle specific types of tasks.

WMS systems focus on optimizing warehouse operations and inventory management, limiting itself to warehouse-related activities, such as picking, packing and shipping. ERP systems, on the other hand, cover a wide range of business functions. They encompass accounting, HR, sales, procurement and more to integrate and manage core business processes across the organization.

Integrating WMS and ERP systems

Integrating your warehouse management system and ERP has many benefits, offering a powerful combination that delivers both operational efficiency and comprehensive business management. You will have end-to-end inventory visibility, using the powers of both systems to provide real-time visibility across the business.

Effectivize the whole order fulfillment process, from sales order creation to picking, packing, and shipping. Once an order is placed in the ERP system, the WMS takes over warehouse operations, streamlining picking and packing processes. This strong coordination reduces lead times, improves accuracy, and speeds up delivery to customers.

A high-quality warehouse management system optimizes storage locations and labor allocation, ensuring that resources are used efficiently. ERP integration extends these optimizations across a wider range of business processes, such as procurement planning and resource allocation. You can also use ERP functionality to trigger actions like replenishment orders, based on alerts from the WMS system.

The WMS immediately updates the ERP system with the associated costs, providing the finance department with real-time, accurate cost data, allowing for more precise financial reporting and accounting. Your business can optimize its cash flow by reducing unnecessary inventory holding costs and improving forecasting, which aligns with the financial goals managed within the ERP system.

Integrating your WMS and ERP creates a holistic business management solution that not only optimizes warehouse operations, but also aligns them with broader business functions such as sales, procurement, and finance. This integration leads to improved efficiency, enhanced data visibility, better decision-making, and superior customer service, all of which drive business growth and profitability.

WMS or ERP with a WMS module?

In some cases, using a best of breed (standalone) WMS makes more sense than an ERP with a WMS module. It often comes down to the complexity, scale, and specific needs of the warehouse operations. Here are some key situations where opting for a standalone warehouse management system could be the better choice:

• Highly complex warehouse operations: if a business has highly specialized or complex warehousing needs, a standalone WMS offers the advanced features necessary to manage these operations efficiently. While an ERP with a WMS module may provide basic inventory and warehouse management functions, it usually lacks the depth and sophistication of a dedicated WMS. Some examples of companies where this might be the case are large distribution centers and businesses with many different warehouses.

• High-volume or fast-moving warehouses: for businesses handling high transaction volumes, a standalone WMS is typically more efficient in managing the flow of goods, optimizing storage, and handling large-scale order fulfillment. This is especially critical in industries like e-commerce and third-party logistics (3PL), where fast fulfillment and precise inventory control is crucial.

• Warehouses with advanced inventory and label optimization goals: standalone WMS solutions often include advanced algorithms and features specifically designed to optimize warehouse layout, picking paths, labor management, and resource allocation. These are critical for businesses seeking to maximize efficiency and minimize operational costs.

• Businesses seeking high scalability: growing, dynamic warehouses need to effectively handle increased inventory, more SKUs (stock-keeping units), higher order volumes, and new fulfillment methods (e.g., same-day shipping, omnichannel). A standalone warehouse management system is better equipped to handle business growth and seasonal variations, especially if you choose a cloud-based option.

• Warehouses in need of flexibility and customization: standalone WMS solutions typically offer a higher degree of customization and are more adaptable to specific operational needs compared to ERP WMS modules, which are often more rigid in their functionality. This includes meeting industry-specific requirements, e.g. in food and beverage, pharmaceuticals or luxury goods, or tailoring workflows to unique business operations.
