A Quick Guide to Software System Acronyms: ERP, WMS, MES & EDI

Companies across a variety of industries—from manufacturing to food processing—use software systems to manage day-to-day tasks, automate business processes, increase operational efficiency, boost productivity, and improve strategic decision-making. Technology such as ERP, WMS, MES, and EDI are more popular than ever thanks to their range of benefits and return on investment.

At the same time, in the world of production-oriented software, there are several system names to keep track of. What is the difference between ERP, WMS, MES, and EDI software? Can these systems be integrated and work together? Which software solution is the right fit for your business operations?

We’ve created a brief guide to these acronyms to help you stay organized.

What Is an ERP (Enterprise Resource Planning) System?

An enterprise resource planning (ERP) system is a comprehensive business management software application designed to manage and automate business processes across all departments of an organization. An ERP system can be immensely powerful, providing tools in a wide range of capacities:

• Accounting, 
• Customer relationship management (CRM),
• Order entry and processing, 
• Purchasing, 
• Ecommerce integration, and 
• Inventory management

These systems also centralize and standardize processes to facilitate the seamless sharing of data, accurate forecasting, and cross-departmental collaboration.

ERP systems are at the very top of the pyramid. Both WMS and MES platforms rely on ERP integration to maximize performance, and an ERP system can also connect with an EDI system to modernize internal and external communications.

What Is a WMS (Warehouse Management System)?

A warehouse management system (WMS) is a software application designed to track, control, and optimize operations within a warehouse center or distribution environment. This system tracks the movement of inventory within a warehouse, uses real-time data to optimize warehouse processes, and provides a complete view of the supply chain.

Thanks to the powerful warehouse management features of a WMS, the system manages inventory from end-to-end—receiving the product, storing the product, locating the product, order picking, product tracking, shipping preparation, etc.

While an ERP system typically has some warehouse management capabilities, a WMS is much more robust.

What Is an MES (Manufacturing Execution System)?

A manufacturing execution system (MES) is a software application that helps manage, control, execute, and optimize manufacturing operations and production work more efficiently and effectively.

MES software can and should handle all the needs of factory floor operations, including:

• Coordinating machines, personnel, and resources to reduce waste and boost efficiency,
• Ensuring quality standards are met,
• Collecing real-time data from the factory floor, and
• Analyzing results to ensure decision-makers have the detailed insights they need to control operations.

With increased traceability, transparency, and visibility, MES allows manufacturing operations a way to better coordinate activities, reduce downtime, and make sure everything is in the right place at the right time.

What Is an EDI (Electronic Data Interchange) System?

An electronic data interchange (EDI) system is a type of software that allows businesses to send and receive information from one computer system to another. The system is based on a standardized format to ensure data is correctly and accurately transmitted to and from internal applications or systems.

By replacing traditional paper-based communication methods like mail and fax with a digital exchange of information, EDI software is designed to reduce human error, improve accuracy, boost efficiency, increase communication speeds, and provide significant cost savings.
