ERP systems track business resources—cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across the various departments (manufacturing, purchasing, sales, accounting, etc.) that entered the data. ERP facilitates information flow between all business functions, and manages connections to outside stakeholders. NetSuite's cloud ERP is a strong Australian solution which is available.
Material requirements planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. Compare a recent review of Manufacturing Resource Planning (MRP) software here here.
A bill of materials (or BoM) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts and the quantities of each needed to manufacture an end product. The BoM provides the manufacturer's part number (MPN) and the quantity needed for each component. It makes sure that what you are ordering – and being delivered with – is complete and correct. A BoM may be used for communication between manufacturing partners, or confined to a single manufacturing plant. InterAcct Software for Manufacturing can help businesses manage BoM as well as a host of other facets of your manufacturing needs. Sybiz Vision offers highly regarded support capabilities as well.
