I am an Indian! Currently staying in Bangalore.
Indians don't buy Technology? This is BS, right?
Indians pay for technology all the time. From the poorest to richest. Just because they don't click on paypal and the money doesn't land in your start up's account it doesn't mean Indians don't pay up. The average levels of Piracy in India will more or less be the same as they are around the world.
Indians pay for things that bring them value. Not just because you built something. And it is you who built it.So first understand what value you bring common Indian masses.
I know of Auto drivers and cab drivers who get costly metering and taxi dispatch systems fitted to their vehicles. And they are really poor people. They are paying for technology, because it brings value to them. Do you know how many people use mobiles phones in India? Even the poorest people might be earning less than $1 a day(I know many beggars who carry mobile phones) use mobile phones in India, and they pay their bills.
I know Temples, Churches, Mosques use scrolling displays outside their compounds for various announcements. The displays survive in tough weather. And they sell. They bought it because it adds value to them.
I know ordinary middle class people, buy handy glucometers( for diabetes/blood sugar level testing) and Nebulizers and Sphygmomanometers(To check their blood pressure levels), Glucometers made by Accecheck. Why do they buy this technology? Because it brings value to them.
Millions of middle class Indians use solar technology and rain water harvesting systems. And they pay for it, you know why? Because it brings value to them.
I can go on and on... Citing examples.
India is like every other country and Indians are like people from any other nation.
People pay up when they see some value in the product. So any time you accuse Indians of not paying up. Ask your self a simple question.
What value does my service/product bring to the people
If you can't come up with a good answer to this question. Really the problem is with your product strategy.
Not Indians. Or India as a whole.
PS:
In this case 'Tax filing' software/means is worth dime for a dozen in this country.
EDIT : To all people who are downvoting this, Truth is bitter. An MVC site which has a thousand clones or which doesn't bring any value is not bound to succeed.
Seriously ask your self what value you bring to the world or why should people buy from you.
