TDS For Partnership Firm Pan

Hi,

We have recently started IT service related partnership firm. We are working on Freelancing website as well and have corporate account there. We have marked that they are asking business PAN for compile income tax rules of Indian Government and they deducting TDS. My question is what will happen when they deposit tax to income tax? As I know we have to file individually ITR for partnership firm, How we can claim TDS?

Thanks!
