So I built Carton, a Framer template for moving companies with a load calculator that does the guessing for them:
→ Tick your furniture room by room (29 real items with real volumes)
→ Watch a drawn van fill up from the floor as you add things
→ Get cubic metres, the right vehicle, the number of trips and a price band, in m³ or ft³
→ Hit Book and the whole inventory travels into the booking form, so the firm gets a list instead of a vague message
