Calculator Resterm — a quote line stays tied to the need that produced it
We wrote selection software for an electric heater maker. The user enters a heating requirement, not a product code, and the software runs the engineering calculation and picks the heater. The selection drops into a basket, the basket attaches to a project, the project to its customer, all held as one chain in MySQL. Because the calculation's result becomes the quote line, nothing is retyped between technical and commercial sides. The payoff is traceability: a quotation reads backwards to the requirement behind it, and holds up months later. Laravel runs it, Vue draws the screen.
