Who is behind One to Many?
A software company building automated takeoff for the window and door industry.
One to Many builds takeoff software for window and door manufacturers, glazing contractors, and dealers. Upload a plan set, get a unit-by-unit schedule — type, size, operation, glazing — ready to quote with your own catalog and pricing rules.
And to clear up the name: if you were searching for the @OneToMany database annotation, this is not that page. We are a construction software company; the name refers to turning one plan set into many correctly counted units.
How we work
Two principles show up everywhere in the product. First, ambiguity is flagged, not guessed: when the drawings and the schedule disagree, a human decides, not a model. Second, onboarding happens on your real bids — the first plan sets we process with you are ones you actually quoted, so the tool earns trust on your own work.
