Presumptive taxation for services

We run a small information retrieval business with only 1 employee for a foreign client and income comes through bank.  we were earlier told that this would come under business since we do akin to jobwork for client. client assigns some file for us to search on net. we fill in data and send back. but now we are told that this wont come under business and is service. Kindly advise if information retrieval on net is job work or service.
