Software cost clarity for founders and product teams

Know what you will build — and what it will cost — before you commit

Answer a guided questionnaire about your application. Lean Do IT compares a traditional delivery estimate with an AI-assisted build from R-SOFT, generates a detailed software specification, and presents a fixed offered price you can accept online.

    Illustrative only. Your actual offered price is calculated from questionnaire answers, COSMIC-style complexity factors, and phase-weighted AI productivity assumptions.

    What you receive

    More than a number on a slide

    Every estimate is designed for procurement-ready transparency — scope, architecture, phases, and a clear path to order.

    Real project

    From Lean Do IT estimate to a live mobile app

    Fluentico is a cross-platform language-learning app built with Flutter. The project started as a Lean Do IT questionnaire and shipped to the App Store and Google Play.

    Process

    From idea to offered price in four steps

      Delivery model

      Fixed price, full ownership, no surprise fees

      Infrastructure, third-party API usage, app-store fees, and client-supplied artifacts are excluded unless explicitly listed in your offer — matching the disclaimers in your estimate report.

      Capabilities

      Built for real software projects

      The questionnaire captures mobile, web, desktop, and backend layers — plus security, compliance, scale, and QA expectations.

      Why it matters

      Buy software development with evidence, not guesswork

      Lean Do IT is designed for teams who need a credible baseline before signing a contract — without weeks of discovery workshops.
