Under the Hood
  1. Traceable & Explainable

    Technical specifications are embedded and matched against historical supplier lines. The result shows comparable products and an interval, so a user can see the evidence behind the estimate instead of being blocked behind a black box.

  2. Context-aware prediction

    Comparable prices are normalized before they are used: aluminium by perimeter, glazing by square metre, then refined for quantity and the pricing tier of the project. That keeps a bulk order from quietly pricing a bespoke job.

  3. AI estimations, deterministic math

    The system estimates supplier costs from history, but every business rule after that stays explicit: direct costs, overhead, fabrication, installation, transport, margin, safety buffer, and VAT are all itemized and reproducible.

  4. Follows the whole quotation lifecycle

    A role-based web app gives employees a guided product and quotation workflow while administrators control business settings. Finalized quotations freeze their parameters, and the system was deployed on the company's own Windows Server.

In the Wild

Unfortunately, this app runs on real client data, so I can't share captures of it publicly here.

This one runs on real client data, so the code stays private. Request a demo and I'll walk you through it directly.
