Hey everyone! š
I am a self-taught teenage developer from India. Over the last few months, I've been working on a big problem: small local retail shops often have terrible internet, causing their billing systems to freeze up during busy checkout hours.
To solve this with zero budget, I built and deployed FnvxTraāa free, offline-first GST billing and inventory platform.
Live Link: š https://fnvxtra.in
š Key Features:
- Offline-First: Uses zero-latency local caching. Once loaded, the web app functions completely offline so checkouts never freeze.
- Merchant Privacy: Because it runs locally, data stays safely on the store owner's browser.
- Automated GST: Handles tax splits and inventory lookups instantly.
- Thermal Printing: Integrates smoothly with standard retail receipt printers.
š ļø The Tech Stack
To keep this project 100% free with zero investment, I built it using frontend web technologies and hosted it entirely on Vercel.
š¬ I need your expert feedback!
As a young developer, I don't have a marketing budget. I am looking for my first 10 tech-savvy users or testers to check it out.
Could you open the app and tell me:
- Does the offline caching load smoothly for you?
- How can I improve the UI layout for a busy shopkeeper?
- Are there any edge-case bugs you found while creating dummy invoices?
Thank you for supporting a student developer! š

Love the offline-first approach! Keeping sensitive financial/billing data entirely client-side is a huge win for privacy and user trust. Building utility apps that solve real, localized problems is the best way to learn and ship fast. Great work!
Thank you so much, Oleksandr! I really appreciate the kind words.
Since I'm a teenage developer learning the ropes, building an offline-first architecture was a fun challenge. If you have a minute, I would love it if you could actually open the live app (fnvxtra.in) and give me feedback on the UI/UX layout.
Does it feel intuitive enough for a local non-tech shopkeeper to manage their inventory? Thanks again!
Spot on, keeping sensitive financial and billing data completely on the client side is a major win for privacy and user trust. Building practical offline-first tools that solve real problems is definitely the best way to ship fast. Awesome project!
