Add invoice lines, HSN/SAC references and the place of supply. All arithmetic runs only in your browser.
Unit prices are treated as GST-exclusive.
Quick note: Use Add GST when the entered unit price is before tax. Use Remove GST when the amount already includes GST and you want the taxable value.

This is a GST arithmetic summary, not a tax invoice or classification opinion. Place-of-supply rules, HSN/SAC classification, exemptions, reverse charge, input-tax credit, composition scheme treatment, TDS/TCS and cess may require separate review.
Use one row per product or service. HSN/SAC is optional. Each line can use its own GST rate and discount.

Classification note: HSN/SAC is recorded for your summary only. Confirm the correct classification and GST rate for the actual goods or services before invoicing.
