Forward GST math
GST = taxable × rate/100. Total = taxable × (1 + rate/100). Standard B2B invoices show all three lines.
Intra-state: split GST equally into CGST and SGST on the invoice face.

Quote vs collection
Exclusive quotes help compare vendors on pretax value. Collect total inclusive of GST from the buyer.
Ahmedabad and Jaipur wholesalers publish ex-GST price lists but invoice inclusive totals—forward mode shows the collection amount clients actually pay.
Inter-state IGST on forward quotes
When the buyer is in another state, the forward total posts as IGST instead of CGST+SGST split. Multiply taxable by 1.18 (or your slab) for the invoice total—the component split changes, not the math.
Export invoices may be zero-rated—forward GST mode does not apply when the supply qualifies for 0% with LUT; confirm with your CA before quoting.
Add GST forward
₹10,000 taxable at 18% → ₹1,800 GST → ₹11,800 invoice total.
