ERP systems are primarily unifying tools, in that they bring important company processes like manufacturing, marketing, inventory management, personnel, customer relationship management or product research under one umbrella. This takes the form of a unified IT package which can control all of the different processes at once.
Most ERP packages are collections of databases. They store company data as it is created, making it comprehensible for managers and storing it for future use. This data could include anything from the bill of materials to product stocks, unpaid invoices or purchase orders. If it affects the firm’s bottom line, it will be processed under the ERP system
