More than 100 years have passed since the beginning of ERP. The economic order quantity (EOQ) model, a paper-based manufacturing system for production scheduling, was created in 1913 by engineer Ford Whitman Harris. When Black and Decker, a manufacturer of tools, was the first business to use a material requirements planning (MRP) system that coupled EOQ principles with a mainframe computer in 1964, it altered the game.
Different production processes were merged into a single system for the first time. Additionally, MRP II offered a compelling vision of how businesses could use software to exchange and integrate organisational data, improve operational efficiency, and decrease waste and inventory.

Despite the fact that the phrases are occasionally used interchangeably, the latest SaaS ERP is a subset of cloud ERP. When used as a multi-tenant system, cloud software products are referred to as software-as-a-service. SaaS ERP is handled by the software supplier, like other SaaS solutions. It mostly employs the multi-tenant paradigm, which calls for clients of a provider to share a single instance of software and the same infrastructure. SaaS ERP is a subscription service, as its name implies, and users are billed either monthly or annually by service providers. The latest ERP results in lower technology costs. A firm doesn't require a huge IT crew to maintain and secure the programme or a data center to host it, which saves money in addition to not having to buy hardware to run a private version of the system. While some SaaS ERP companies have tiered pricing based on company size and the number of resources needed, many charge per user.

Key company processes including accounting, inventory management, order processing, and customer data management have out-of-the-box capabilities.
As the firm expands, there is no need to deploy servers or make new infrastructure investments.
