What a GST invoice must show
Any word processor or free billing tool can produce a GST invoice, as long as it carries the mandatory fields.
- Your GSTIN, a unique serial number and the date.
- Buyer details and GSTIN for B2B, plus place of supply.
- HSN/SAC codes, taxable value and the CGST/SGST/IGST split.
Step by step
- Open the official GST portal or a free GST tool.
- Enter your details for the period or transaction.
- Review the result and keep a copy for your records.
Rates change at GST Council meetings, so always confirm the current figure for your exact HSN or SAC code on the CBIC rate finder or the GST portal before you print it on an invoice.
