The founder
Built by Gottam Sai Ganesh Raju.
I'm a B.Tech graduate in Computer Science (AI & ML) from Pileru, Chittoor. I started GSR Devo to give small businesses in India the kind of software larger companies take for granted: fast web apps, reliable desktop tools and payments that just work.
You work directly with me, from the first call to the last bug fix.

Questions
Things clients usually ask.
Do I own the source code?
Yes. After the final payment, the full source code, designs and accounts are handed over to you.
Which payment gateway should I use?
For most Indian businesses we recommend Razorpay or PhonePe PG for UPI and cards. If you sell abroad, we add Stripe or PayPal. We help with KYC and gateway approval.
Can one app run on web, desktop and mobile?
Yes. We build one backend and connect separate web, desktop and mobile front ends to it, so data stays in sync everywhere.
How do I pay GSR Devo?
By UPI, bank transfer, card or international payment, in three parts: 40% to start, 40% at the demo and 20% at launch. Every payment gets a GST invoice.
What happens after launch?
Every plan includes free support after launch. After that, the yearly care plan covers hosting, backups, security updates and small changes.
