Scalability is a crucial consideration because it ensures that the ERP system can accommodate the growth of the business without performance degradation. As a business expands, its transaction volumes, user counts, and operational complexities increase. A scalable ERP system can handle this growth, adding new functionalities or modules as needed without requiring a complete system overhaul. This not only supports long-term business development but also provides a better return on investment by extending the useful life of the system.
