Hey Indie Hackers! I’m vishnu, a Class 12 student. Over the last 1.5 to 2 months, I built Audit Engine Pro—a production-ready, air-gapped financial audit automation platform.
Here is the backstory of how I built it, the technical decisions I made, and why I’m putting it up for acquisition.
My father spent years working in finance, and seeing the day-to-day operations opened my eyes to a huge problem in accounting and compliance: manual financial auditing is slow, expensive, and prone to human oversight.
Most internal audit teams and CPA firms rely on manual cross-referencing, bloated enterprise tools, and Excel spreadsheets to review General Ledgers and execute Standard Operating Procedures (SOPs).
I wanted to fix this. My goal wasn't just to script a minor helper tool—I wanted to build an automated engine that executes compliance checks deterministically, faster, and far more accurately than humanly possible.
Balancing Class 12 schoolwork with full-stack development meant every hour had to count. Over 1.5–2 months, I logged 400+ engineering hours building the system from scratch to version v0.9.19.
Here is what went into the architecture:
Engine Core: Built using Python and Pandas to execute heavy financial data processing locally and offline-first (air-gapped for maximum security).
14 SOP Modules: Hardcoded automated audit checks covering GL review, balance sheet flux analysis, transaction sampling, and compliance verification.
Flux Engine: Automated variance and trend analysis designed to catch anomalies in real time.
141 Regression Tests: Built a comprehensive automated test suite to ensure 100% deterministic outputs and zero mathematical drift.
Web Console & Setup Installer: Built a web interface and local licensing architecture so non-technical auditors can install and run it without touchpoints.
What started as an attempt to solve my father's operational pain points evolved into a complete, standalone B2B software asset.
Because I am currently focusing on my studies and upcoming exams, I don't have the bandwidth to run a full B2B sales cycle, do enterprise outreach, or handle long customer acquisition pipelines. The codebase is complete, fully tested, and ready to be commercialized as a B2B SaaS or enterprise internal tool.
I’ve valued the project at $16,000 USD, which strictly reflects the replacement cost of 400+ hours of full-stack R&D. It's built for a buyer, agency, or founder who wants a turnkey shortcut into the financial software space without spending 6 months in core development.
