GST INVOICE

A GST invoice is a legal document issued by a seller to a buyer showing sale details, GST rate, and GST amount charged. It serves as proof of taxable supply under GST law.

A proforma invoice is a preliminary bill issued before the final sale. It’s not a tax invoice, but an estimated cost used for quotations or customs.

1. Enter seller & buyer details (name, GSTIN, address).
2. Add invoice number & date.
3. Add items (HSN/SAC, qty, rate, GST%).
4. Calculate CGST/SGST or IGST.
5. Generate and print / save as PDF.

GST means Goods and Services Tax — a single tax on supply across India that replaced multiple indirect taxes like VAT, Service Tax, and Excise Duty.

GST-registered businesses must issue GST invoices for taxable sales (traders, manufacturers, service providers). Thresholds generally apply (often ₹20L / ₹10L for special category states).

GST Amount = (Original Price × GST Rate) / 100

Example: ₹1,000 at 18% GST → GST = ₹180
