Some clients prefer to send "check" or "direct bank transfers". However, I'm not sure how that can work in our situation. Our company bank account is with Indian bank (who has intermediary account at JP Morgan - NY). Any other recommended channels to receive invoice payments overseas (especially India)?
Check out what Vio.ca is doing in this space - truly innovative.
Also look at WeTransfer and Xoom - not sure if they will specifically work for you, but there are quite a few companies offering similar services and hopefully one of them will handle transfers to Indian accounts. Where are you sending money from? If it's the US, you'll have more options.
