Yes, you can easily receive a payment in BTC following these steps:
1) Download a Bitcoin wallet. A Bitcoin wallet is a software which you can use to store, send and receive bitcoins. There are many different types of Bitcoin wallets but I recommend using one of these:
Install procedure is quite easy. You can find plenty of information on the internet about this or you can email me at firstname.lastname@example.org, I'm happy to give you some hints to get started with Bitcoin
2) When you have installed a wallet you will see that the wallet has a "receive" tab where many Bitcoin Addresses (in this form: 1Ht7brsfdt8qG1QkBnku1MWwoPRWNwQfgL) are shown. You can choose one of those addesses and that becomes "your account" where you can receive Bitcoin transactions (as in example the payment you want to receive from your client). Just copy paste one of those receiving BTC address from your wallet to your client and he will know that he has to send BTC to that "account" you just gave him to execute the payment towards you.
3) You can exchange BTC to FIAT currencies, including INR, on so called cryptocurrencies exchanges. I have made a list here, and there are many India Based exchanges which can turn to be useful to what you are looking for. Check the list here : https://bitcointalk.org/index.php?topic=3140406.0
I hope this helped.
Enjoy the revolution of Bitcoin tech ;)
