MRP (Material Requirements Planning) and ERP (Enterprise Resource Planning) systems are vital tools that support resource management in companies. Although both software categories aim to optimize processes, there are fundamental differences between them. The choice between an MRP and an ERP system depends on the specifics of a company’s business. An MRP system focuses on efficient material planning, while ERP offers a broad spectrum of functions, integrating the entire company and supporting its growth in a dynamic business environment.
MRP systems - what are they?
An MRP system is a tool that focuses on managing the materials required for production. It analyzes the need for raw materials, components, and finished products and then plans their purchase or production. MRP supports precise warehouse management and eliminates the risk of shortages or excess materials.
ERP Systems - what are they?
ERP systems are advanced solutions that integrate different areas of a company’s operation, such as finance, human resource management, production, or logistics. It runs on a single platform, which allows for the effective exchange of information between departments.
