GST Invoice Total Calculator
Build a multi-line GST invoice total with discount, multiple rates and the tax breakup — the figure that goes on the bill.
Formula
Trade discounts shown on the invoice reduce the taxable value (GST is charged on the net); post-sale discounts need a credit note. A compliant tax invoice also needs GSTIN, HSN/SAC codes, place of supply and an invoice number series — this computes the arithmetic the rest of the format wraps around.
