ERP systems don’t literally cost an arm and a leg. But they aren’t cheap by any means. There are massive upfront costs related to the software itself, enormous fees related to implementation, oh and, let’s not forget the hardware. But, these aren’t even the worst of it. The biggest cost is the loss of productivity and inability to work while you are getting the system up and running. All of these expenses come up front with no reliable budget and no reliable timeline.
