This mainly depends on which company's ERP you use. Different companies have different requirements, and generally they will provide a suggested configuration. As far as I know, if it is a C/S product, basically the mainstream desktop can be used as a server, and it can be done within 10,000 yuan. If it is a B/S product, the requirements will be higher if it is developed in JAVA. Personally, I think the allocation between 10,000 yuan and 30,000 yuan should meet the requirements.

According to my experience in these years, if it's ERP of a big company and 20 users use it, the desktop within 10,000 yuan should be able to meet the demand. The server still recommends buying IBM.
