We build software that works
where the internet doesn’t.
Yojika Systems is a software company in Tamil Nadu. We make our own offline-first products — and we build the same class of thing for other people: websites, apps, and the automation that runs behind them.
- ~15 MB
- Our billing app’s install size. The market leader’s is ~250 MB.
- 22
- Official Indian languages our invoices print in.
- 12
- Languages our content pipeline publishes in, daily, unattended.
- 0
- Servers you need for a site we build. Static, on a CDN.
Four things, done properly.
We are deliberately narrow. Each of these is something we operate in production for our own product, which is why we can quote a real price and a real timeline instead of a discovery call.
| Service | What you get | Timeline |
|---|---|---|
| 01 Website development | Fast, static, search-visible sites that do not rot. | 2–3 weeks |
| 02 App development | Offline-first Android, iOS and Windows apps from one codebase. | 6–10 weeks |
| 03 Content automation | A publishing pipeline that runs daily without you in it. | 2–4 weeks to first automated publish |
| 04 Marketing automation | The unglamorous plumbing between a lead and a paying customer. | 3–5 weeks |
Yojika — GST billing that never asks for the internet.
Offline-first billing software for Indian small shops, on Windows and Android. Built by someone who ran a kirana store and used the competitor at his own counter for a year.
- Works with the network unplugged — not "syncs later", genuinely offline
- Installs in ~15 MB where the market leader needs ~250 MB
- Prints invoices in all 22 official Indian languages
- Windows and Android from one Flutter codebase
Three commitments, in plain words.
Offline is the default, not the fallback
Most software assumes a connection and degrades badly without one. We build the other way round: the local database is the source of truth, and sync is a background detail. It is the harder architecture and the only one that survives an Indian retail counter.
We ship it before we sell it
Every service on this page is something we run in production for our own product first. The content pipeline we would build for you is the one publishing on yojika.com at 06:49 every morning.
You own the whole thing
Source in your GitHub organisation, deploys on your Cloudflare account, model keys billed to you at cost. Nothing we build needs us to keep running.

One call, then a written scope with a fixed price. If it isn’t something we should be doing, we’ll say so and point you somewhere better.
