Tds on payment to non resident in foreign country

Below are the details:

• Person in Russia have developed a web service similar to gmail being served from USA.
• Customer of this services are based in other countries ( excuding india )
• My client has to pay 50% of profit made on sales of this service to person in Russia.

I want to know if TDS is applicable on such payment or not? And how to remit this money to person in Russia?
