I've some doubt about GST, Suppose Company created a Sales Order and there was 4 partner with deferent location,

Company from State A

Sold to Party from state B

Just want to know who will be the responsible for GST Tax.

If Bill to Party from D state then How to calculate Tax of Ship to Party "E"
