> It's also kinda unique This is why off the shelf solutions aren't typically used. I looked into creating an MRP software a few years back. What I found is that every single company has their own process that is incompatible with everybody else's and they aren't interesting in changing it (it works for us!) That's the reason MRP/ERP systems are so expensive and complicated. It has to be flexible enough to work for everybody. That takes a lot of developer time to create, generates a lot of bugs, etc. It also makes setup and integration a daunting task, which is why SAP integrators can charge $7k/hr (as somebody else in this thread mentioned). The developer time required also makes them extremely expensive, which is why most ERP packages focus on billion dollar global companies; they can afford it.
