Mixed assembled goods that do not fit a single vertical.
Components arrive, get assembled into products, and ship. The specifics vary enormously, but the shape is consistent: a bill of materials, a build, stock consumed, finished goods created. Complexity arrives with sub-assemblies, with kitting for customers, and with the moment you start committing to orders further out than your supplier lead times.
Buying inventory software and discovering it does not manufacture. inFlow's Inventory plans do not include bills of materials or work orders at all. That requires the separate Manufacturing product line, at a higher price. Read which product line a quote refers to.
Do you need full MRP here?
It depends on your horizon. If you build to stock against short lead times, reorder points are fine. If you commit to dated customer orders and your suppliers take weeks, you want the real thing.
