FAQ

A GST-compliant invoice must include: seller and buyer GSTIN, invoice number, date, HSN/SAC code, taxable value, GST rate, CGST+SGST (intrastate) or IGST (interstate), and total amount. Always consult a CA to ensure full compliance.

Use CGST + SGST when the seller and buyer are in the same state (intrastate transaction). Use IGST when the transaction crosses state boundaries (interstate). The total GST rate is the same — only the split differs.

This tool generates a reference invoice for convenience. For official GST filings, the invoice must comply with GST Invoice Rules 2017. Consult a CA or use government-approved accounting software for legally binding invoices.

For goods: invoice must be issued before or at the time of removal. For services: within 30 days of supply (45 days for banks/NBFCs). Late invoicing can attract penalties under GST law.
