As per the new government norms, GST is applied differently for intra-state and inter-state sales. GST levied on the intra-State sales by the Centre is known as Central GST (CGST) and that by the States is known as State GST (SGST). Whereas for inter-state sales, only IGST (Integrated GST) is applied which is directly paid to Central Government. 1- Applied GST appears on the order view, the invoice view, the credit memo view, the new order email and the PDFs. 2- Shipping origin has to be different from warehouse origin in order to apply IGST. 3- GSTIN is displayed on the invoice and the credit memo as well. 4- SGST, CGST, and IGST are automatically calculated on the basis of applied tax classes.
