WMS Deployment

Choosing a WMS is not only about functions. You also need to decide where the system will run. For most businesses, that means choosing between: Cloud WMS and On-Premise WMS Both can support receiving, putaway, inventory, picking, shipping, barcode scanning, handheld PDA operations, and ERP integration. The difference is mainly in how the system is hosted, maintained, accessed, and controlled.     Quick Answer   Choose Cloud WMS if you want: faster deployment less local IT infrastructure easier multi-site access simpler updates easier remote support   Choose On-Premise WMS if you need: internal network deployment local server control restricted external access company-managed databases specific IT or security policies   For many small and medium warehouses, cloud is easier to start with. But if your IT policy requires the system to stay inside your own network, the decision changes immediately.   What Is Cloud WMS? Cloud WMS is hosted on cloud infrastructure and normally accessed through a browser or network connection. Warehouse operators may still use the same hardware: handheld PDA barcode scanner barcode printer RFID reader The difference is where the central system runs. A typical structure is:   PDA → Network → Cloud WMS   Cloud deployment is often chosen by companies that want faster rollout, centralized access, and less local server maintenance.   What Is On-Premise WMS? On-Premise WMS runs inside the customer's own IT environment. A typical structure is:   PDA → Internal Network → Local Server   This usually means the customer is responsible for more of the infrastructure, including: server database network backups system maintenance This model is often chosen when the system must stay inside an internal network or when company policy limits external access.   Cloud WMS vs On-Premise WMS: Main Differences   Factor Cloud WMS On-Premise WMS Deployment Usually faster More infrastructure preparation Local Server Usually not required Usually required IT Maintenance Lower internal burden More internal responsibility Multi-Site Access Easier Depends on network design Remote Access Easier Requires configuration Updates Usually provider-managed Usually customer-managed Data Environment Cloud-hosted Customer-controlled Internal Network Only Less suitable in some cases Often more suitable Scalability Easier to expand Depends on local infrastructure     This table gives a quick overview, but the real decision usually comes down to your IT environment.     Cost, Deployment and Maintenance   Cloud WMS usually reduces the need to build local server infrastructure before launch. That can make implementation faster, especially for smaller companies without a dedicated IT team. On-Premise requires more preparation. The organization may need to configure: servers databases network permissions backup policies internal access Cost also works differently. Cloud WMS usually involves software subscription, users, modules, implementation, and connected hardware. On-Premise may involve more upfront infrastructure and ongoing internal maintenance. The important question is not simply: Which one is cheaper? A better question is: Which model creates less total IT workload and cost for our company over the next few years?   Real FYJ Project Experience: Cloud WMS for a High-Volume E-Commerce Warehouse   In one FYJ warehouse project in Thailand, the customer handled around 500 orders per day and approximately 3,000 SKUs. The project used a Cloud WMS together with barcode printing and scanning, replenishment alerts, ABC and slow-moving inventory management, multi-warehouse functions, and mobile picking. After implementation: Inventory accuracy improved from 92% to 99.5% Shipping errors decreased from 3% to 0.5% Warehouse walking distance decreased by about 40% Inventory turnover improved from 75 days to 45 days Daily closing could be completed in under 10 minutes For this type of operation, cloud deployment made sense because the warehouse needed centralized, mobile, and multi-warehouse access without building a more complex local server environment.   Multi-Warehouse and Remote Access   This is where Cloud WMS often has a practical advantage. If a company operates several warehouses, cloud deployment makes it easier for headquarters and different locations to use the same platform. Management can view: stock by warehouse transfers inbound status outbound status inventory changes without maintaining separate local systems. On-Premise can also support multiple warehouses, but the company usually needs more internal network planning between sites. For a single warehouse, this difference may not matter much. For five or ten locations, it becomes much more important.   What Happens If the Internet Goes Down?   This is one of the most practical questions buyers should ask. Cloud WMS depends more heavily on network connectivity. Before choosing it, ask: Can the PDA work offline? Can transactions be stored temporarily? What happens during receiving if the network fails? What happens during picking? How does data synchronize after reconnection? For warehouses with unstable internet, this can be more important than many software features. On-Premise systems can often continue operating inside the local network, depending on the architecture.   When Local Deployment Becomes the Obvious Choice   In some FYJ projects, the deployment model is actually decided before software functions are discussed. If the customer's requirements include: internal network only local server restricted external access company-controlled database strict IT policy then cloud deployment may already be unsuitable. FYJ's software portfolio supports both cloud deployment and local/private deployment, allowing the architecture to be selected according to the customer's IT environment. This is an important point: On-Premise should not be chosen simply because it “sounds more secure.” It should be chosen when local control is a real requirement.   ERP Integration: Cloud or On-Premise Can Both Work   ERP integration is not determined only by the deployment model. Both Cloud and On-Premise WMS can integrate with ERP if the systems provide suitable interfaces. Before implementation, define: Where are SKUs created? Where are purchase orders created? Where are sales orders created? Which system owns inventory? How are adjustments synchronized? Is real-time synchronization required? If these questions are not clear, employees may end up entering the same transaction twice. That defeats one of the main reasons for introducing WMS.   Does Deployment Change Warehouse Hardware?   Usually, not much. Both models can use: handheld PDA barcode scanner barcode printer RFID handheld reader fixed RFID reader RFID printer barcode or RFID labels The warehouse operator may perform exactly the same action: Scan Product → Scan Location → Confirm Quantity What changes is where the data goes. Cloud PDA → Network → Cloud WMS On-Premise PDA → Internal Network → Local Server So Cloud vs On-Premise is mainly a software architecture decision, not a warehouse hardware decision.     Which Model Fits Your Warehouse?   Choose Cloud WMS when: you want faster deployment your IT team is small you have several warehouses remote access is important your internet connection is reliable you expect the operation to grow   Choose On-Premise WMS when: the warehouse must operate inside an internal network external access is restricted the company requires local servers IT staff want direct infrastructure control company policy requires local deployment   If both models are technically possible, then compare total cost, IT workload, scalability, and future integration needs.   WMS Deployment Decision Matrix   Your Situation Better Starting Point Small IT team Cloud WMS Need fast rollout Cloud WMS Several warehouse locations Cloud WMS Remote access required Cloud WMS Rapid expansion expected Cloud WMS Internal network only On-Premise Local server required On-Premise External internet restricted On-Premise Company controls IT infrastructure On-Premise may fit ERP integration required Either Barcode or RFID required Either Internet is unstable Evaluate  On-Premise or offline capability   Questions to Ask a WMS Supplier   Before deciding, ask: Do you support Cloud, On-Premise, or both? Where will our data be stored? Who manages backups? Who handles updates? What happens if the internet fails? Can handheld PDAs work offline? Can several warehouses use the same system? Can the WMS integrate with our ERP? What IT infrastructure is required? Can the deployment model change later? If a supplier cannot answer these clearly, the deployment architecture is probably not fully defined yet.   How FYJ Approaches WMS Deployment   FYJ supports both cloud-based and local warehouse management deployment. The choice usually starts with a few practical questions: How many warehouses are involved? Does headquarters need remote access? Is the internet reliable? Does the customer have an internal IT team? Is local deployment required? Does WMS need ERP integration? Will operators use handheld PDAs? Will barcode be enough, or is RFID required? The deployment model is selected after these requirements are clear. In practice, we do not recommend Cloud or On-Premise simply because one is newer. The system has to fit both the warehouse workflow and the customer's IT environment.   Frequently Asked Questions   Is Cloud WMS better than On-Premise WMS? Not always. Cloud WMS is often easier to deploy and maintain. On-Premise is more suitable when internal network or local server control is required. Is Cloud WMS cheaper? It may reduce upfront infrastructure cost, but total cost still depends on subscriptions, users, integration, hardware, and long-term operation. Does Cloud WMS require internet access? Usually yes. Ask whether the system or PDA supports offline workflows when connectivity is interrupted. Is On-Premise WMS more secure? Not automatically. It gives the customer more direct control over the local environment, but actual security depends on system design, access control, maintenance, and IT management. Can both models integrate with ERP? Yes, if suitable APIs or integration methods are available. Can Cloud and On-Premise WMS both support barcode and RFID? Yes. Barcode and RFID are data collection technologies and can be used with either deployment model when supported by the software.   Conclusion   Cloud WMS and On-Premise WMS can both support warehouse operations effectively. For many growing warehouses, Cloud WMS is easier to deploy and scale. For organizations with controlled internal networks or strict local infrastructure requirements, On-Premise may be the more practical choice. The key question is not: Which model is better? It is: Which model fits our IT environment, warehouse workflow, and future growth? That is the decision that should guide the WMS project.
