We have received Rs.100000 advance payment against goods to be sent and invoiced next month after 30 days. whether gst will be calculated on 100000/- i.e. 18000/- @ 18% or shall be considered inclusive of gst like 100000 x 100/118=84746+15254=100000/-
What document shall be issued for this advance payment and gst deposited on the same to purchaser?
