    Can anyone tell me the difference between MRP and ERP?  Preferably in simplistic terms if possible?



    If you are refering to just MRA and not MRP II the difference is that MRP is planning material requirments only where ERP (Enterprise Resouce Planning) is looking at all defined aspects of your enterprise.



    The ‘M’ in MRP is ‘Materials’. MRP is the planning and control of materials used in a manufacturing/assembly process. It’s usually an inventory system which tells you what you need and when you need it allowing you to keep your inventory value to a minimum without actually running out of anything.
    The ‘E’ in ERP is Enterprise. This is the whole shooting match with all the bells and whistle, usually MRP with additional accounting, HR, manage your employees, vegicles, assets etc etc.
    Not everyone needs MRP or ERP though.
    Here’s some ad copy from the miniMrp website at
    miniMRP for Windows 98/Me/2000/XP and Windows Vista is a new, easy to use inventory manager with some additional features usually only found in larger ERP/MRP systems.
    miniMRP may look like a small package but that’s because it doesn’t waste space on rarely used features that nobody uses anyway.
    why maintain an overweight, over-complex ERP/MRP system when all you really want is something that will manage an unlimited number of inventory items and when required, build, manage and cost single and multilevel parts lists and Bill of Material of almost any number of levels or complexity.
    If you need more than a basic inventory system but don’t want the bother and associated running costs of an oversized ERP/MRP system then there’s a good chance that miniMrp is all the software you’re looking for.
    Take a look at the minimrp website at
