Your inputs set the price. AI helps with proposal language, not prices or specs.

A clearer estimating workflow

The math is yours. The words get a hand.

Quillduct is designed around the way contractors build an estimate: with their own costs, their own judgment and a final review they control.

  1. 01 / INPUT

    Set the numbers you trust

    Enter your price books, labor rates, materials, quantities and markups. The estimate starts with the information your business supplies.

  2. 02 / CALCULATE

    Keep pricing deterministic

    Calculations use your inputs. AI can help draft proposal descriptions, but it does not make up prices or technical specifications.

  3. 03 / REVIEW

    Polish it before it leaves

    Edit and review each proposal before sending it, then export a PDF for your customer.

Built around contractor control

Helpful writing. No mystery math.

AI has a narrow job: help turn your estimate into clear proposal descriptions. Your price book and rules stay the source for amounts and specifications, and you review the finished proposal before sending.
