Build something that works
I haven't used Zwitch before, but it seems like it's a relatively new service so there's not much commentary on it yet. But it seems like it is India-specific, so that may be just what you need. Other than Zwitch, you should research India specifically, but the popular payment alternatives I recommend are Paymill, Braintree, and PayPal. There are also many smaller payment providers, but those are largely regional or country-specific so you'll need to look into them on your own.
