Ahmedabad, India • Founded 2024
Doctors were using pen and paper for billing in 2024. He digitized it. ₹2.6L MRR from 165 clinics
I have chronic allergies, so I visit doctors a lot. I noticed something crazy-in 2024, most small clinics in Ahmedabad were still writing bills by hand. Doctors would scribble on a pad, hand you a carbon copy, and that's it. No digital record, no GST compliance, no way to track revenue properly. I started asking doctors why they don't use software. Answers ranged from 'Too expensive' to 'Too complicated' to 'Don't trust computers'. But when I dug deeper, the real reason was simpler-existing medical billing software is designed for hospitals, not single-doctor clinics. Too many features, too expensive (₹50K+ upfront), too complicated. There was a massive gap in the market for simple, affordable clinic billing software.
I visited 30 clinics in Ahmedabad-general physicians, dentists, pediatricians. Asked them a simple question: 'If I built billing software that's as easy as WhatsApp and costs ₹1,500 per month, would you use it?' 23 out of 30 said yes immediately. Several doctors told me they'd been looking for something like this for years. The validation was so strong that I started collecting advance payments. 8 doctors gave me ₹4,500 each (3 months advance) before I'd even started building. That ₹36,000 became my development fund.
I kept it stupidly simple. Doctors aren't tech-savvy, so the UI had to be brain-dead easy. Patient name, consultation fee, medicines prescribed, print bill. That's it. Added GST calculation, digital signature for prescriptions, and a basic patient history feature. No complex inventory management, no hospital ward tracking, no appointment scheduling. Just billing. Built it as a web app using React and Firebase because I needed it to work on any device-computer, tablet, phone. Doctors could bill patients from their phone if needed. Took 2 months to build the MVP. Another month to add thermal printer support because every clinic uses those small bill printers.
Launched by going clinic to clinic in Ahmedabad with a tablet. I'd walk in, wait for a gap between patients, and pitch the doctor. 'Sir, can I show you something for 3 minutes?' Most doctors were surprisingly open. I'd do a live demo-create a fake patient, generate a bill, show how GST is automatically calculated. The pitch was always the same: 'Save 1 hour every day, never worry about GST notices, pay only ₹1,500 per month'. If they showed interest, I'd offer to set it up right there-add their clinic logo, configure their fee structure, print a test bill. That hands-on approach converted like crazy. First month: 18 clinics signed up.
Doctors talk to each other. Medical associations, WhatsApp groups, lunch meetings-they're constantly networking. One happy doctor recommended me to five others. I also started offering free GST compliance help. Many doctors were terrified of GST but didn't understand it. I'd spend 30 minutes explaining their obligations, showing them how my software handles it automatically. That built massive trust. By month 7, I had 120 clinics. Then I hired two field sales people to cover more areas of Ahmedabad. Currently at 165 clinics paying ₹1,599/month average. ₹2.6L MRR. Planning to expand to Surat and Vadodara next quarter. The churn is basically zero-once a clinic digitizes, they never go back to paper.
Visit 50 small businesses in any offline industry-clinics, shops, salons, gyms. You'll find 10 problems that can be solved with simple software. Most SMBs aren't using any software at all. They're not choosing between your product and a competitor. They're choosing between your product and pen-and-paper. That's a much easier sale. Build something simple, price it affordably (₹1K-2K/month), and sell it in person. That's a guaranteed ₹5L+ MRR business in any tier-1 or tier-2 city.
