This is the tough part. Particularly when you would be dealing with several new clients every day, and it is not going to be just 1 payment every month. Several small payments come every month, and with that money you should be keeping your company running.

If you are running an India based Hosting company, several of them being there already serving the whole wide world, paypal should be your first choice. You can register for a business account, get it verified with your credit card, and integrate it with your site. If your site is a basic html site, you could paste payapl buttons on the page with which your clients could get into subscriptions, and terminate it when they want to discontinue. Paypal is a service that is used world wide, and you can withdraw money to your indian bank accounts, and you dont really need an offshore bank account in the US or UK to receive payments which you can wire to India.

Otherwise, you could opt for a USD payment processor which can process credit cards for you. But this will need an offshore bank account into which you could collect the payments. You could always bring any amount of money into India, without any taxes.
