GSTIN and tax lines
Show your GSTIN and, for many B2B supplies, the client’s GSTIN. Break out tax clearly. Rename or split Taxes into CGST/SGST or IGST to match the supply.
Keep net, tax, and gross readable — see what to include on an invoice.
HSN and SAC codes (rate depends on the code)
GST percentage in India follows the Harmonized System of Nomenclature (HSN) for goods and the Services Accounting Code (SAC) for services — not a single rate for every PDF.
Before you send a client bill, confirm the code and rate on the [GST portal](https://www.gst.gov.in/) or with your chartered accountant. A generator's 18% starter is a common services shortcut, not legal advice for your supply.
- Put HSN/SAC in the line description or Notes when your process requires it (e.g. “Consulting — SAC 9983”)
- Intra-state B2B: often CGST + SGST (each half of the total GST rate)
- Inter-state B2B: often a single IGST line for the full rate
- Place of supply rules decide CGST/SGST vs IGST — wrong split is a common audit issue
- Government e-invoice / IRN (Invoice Reference Number) is separate — this PDF tool does not generate IRNs
Rates and place of supply
Do not leave an 18% starter on a supply that uses another HSN/SAC rate. Clear Taxes if you are not GST-registered.
Place of supply decides CGST+SGST vs IGST — confirm before you lock the PDF.

Mistakes that get PDFs sent back
Missing client GSTIN on a B2B bill, CGST+SGST on an inter-state supply (or IGST on a clearly intra-state one), and an 18% leftover on a different HSN/SAC rate are the usual bounce-backs.
Do not treat this PDF as an IRN. If you are required to report e-invoices, complete that on the official portal and keep this file as a client-facing copy only.
