You have stated that you have purchased a software for use and it appears that it is not a package specially developed to address your requirements in which case it is a contractual obligation on the part of the supplier and the same is liable for TDS under Section 194J being professional services rendered.
Normally, in the case of any software only the license is given for the use of the software. It has been clarified by the Supreme Court of India, in the case of TCS V State of Andhra Pradesh (2004) 271 ITR 401 (SC) that granting of such licenses for th use of software is in the nature of a payment for a copyright. Just as a printed book is a copyrighted article, a standard software i.e Shrink wrapped software (though may be modified) is only a goods liable for sales tax. In such a transaction, the primary object of the transaction and intention of the parties, is to avail of an article for use.
Therefore, no TDS liability arise in your case.
Good Bye! Cheers!!
