The design brief for custom software is nothing like a website's. Nobody here is being persuaded; someone is working, probably in a hurry, quite possibly on a phone in a truck. So the pipeline is drag-and-drop with per-stage totals, the overview answers “how are we doing” in one screen, and the week view flags weather on outdoor jobs because weather is what actually reshuffles a coastal contractor's schedule. The invoice tracker raises overdue bills on its own, since relying on memory is the exact failure being fixed.
