RCM under GST

I m working for a company worked for development sector (NGO) wherein 350 persons working. 250 person is on company roll and rest person worked as consultant. We issue a offer letter to all consultants and they worked for company 8 hrs 6 days in a week. We also deduct 10 deduct TDS from the gross amt paid. As of now we booked a expense as fundraising cost and no rcm on service tax machanism. Now my question after gst implementation we need to booked the fundraing cost with GST RCM.
