The difference small business between ERP and MRP can at least be reviewed from the following aspects.
1. Industry
MRP can also be part of ERP, but it also depends on the industry. MRP is usually used for manufacturing, while ERP can be used for various industrial companies. ERP can be used by manufacturing, retail, and even services.
That way the environment owned by the ERP system is more complex than MRP.
2. Business Process
ERP can run almost all business processes in the company's industry from manufacturing, financial planning, order management, distribution, purchasing, and so on. Meanwhile, MRP only functions to carry out the material planning process.
3. Technology
Supporting technology for ERP systems is very complete, for example network, database, and hardware. These three are often considered the most important components to support this system. While Material Planning or MRP only refers to software only.
4. Project Scope
Because the ERP system is supported by complete technology, the scope for carrying out projects is also wider than MRP. Because complete technology can run almost all business processes effectively and efficiently.
That's a little review of the differences between ERP and MRP. They both look more the same, but are actually different. From the description above of course we can know that ERP has more benefits than MRP.
