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.
Your preliminary estimate
Trust & compliance
Built for confident procurement decisions
Savings explorer
See how AI-assisted delivery changes the math
Adjust scope inputs to explore indicative savings. Final pricing always comes from your completed questionnaire and fixed offered price.
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.
