GST is a combination of both VAT and ST so while Registering (can be migrating or fresh) you need to look for the right HSN code for VAT related items and SAC code for Service related items.
Sir
I am gst registered now i want to raise service invoice to co. for claiming some claims
My C.A is saying first to register under some service head under gst and saying me to ask co. Under which head we should register
Is there r different service head or we are already registered
