Hello Sir,
Firstly on what basis did your client deduct 10%, they were correct in deducting it on the whole amount but they should deduct it as a contractor and rate should have been 1 or 2% and not 10%.
So they are correct in deducting TDS, but you have to discuss the rate with them.
Trust this clarifies your query.
Feel free to call / get back in case of further clarifications.
Thanking You.
