How the totals are calculated
Each line’s taxable value is quantity × rate minus any discount. GST is calculated per line in paise, so there are no rounding surprises. For same-state supplies, it is split equally between CGST and SGST. The grand total can be rounded to the nearest rupee and the round-off is shown separately, as is common practice.

The rate for your specific goods or services depends on its HSN/SAC classification. Older 12% and 28% rates can still be entered as a custom rate for past invoices.
