Hi Naresh,
I understand that you are inquiring about whether or not Human Resource companies have their own dedicated software or not and so to answer your question, it depends on the magnitude of the Human Resource companies we are talking about. Generally Tier A companies have their own software to manage their HR related services but when it comes to Tier 2 and Tier 3 companies, generally they buy from third party companies who provide these kinds of services. BEST WISHES!
