A practical checklist of fields GST-registered businesses should include on tax invoices — plus what a simple PDF tool can handle today.
If you are GST-registered in India, your invoice is not just a payment request — it is a compliance document. Missing or wrong fields can delay input tax credit (ITC) for your client and create headaches during audits. Use this checklist before you send any bill.
Every tax invoice should clearly show: (1) your legal name, address, and GSTIN; (2) a consecutive invoice number and date; (3) the buyer's name, address, and GSTIN (if registered); (4) place of supply; (5) line items with description, quantity, rate, and taxable value; (6) HSN or SAC codes where applicable; (7) tax breakdown — CGST/SGST for intra-state or IGST for inter-state; (8) total invoice value in words and figures; (9) your signature or authorised signatory details.
For B2C sales below the threshold where a full tax invoice is not required, a bill of supply may apply instead — rules depend on your registration type and turnover. Always confirm with the official GST portal or your chartered accountant.
Freelancers and small businesses often start with a simple PDF that includes business name, client details, line items, and a single tax percentage. That works for early-stage billing, but once you cross GST registration limits, you must align invoices with the format prescribed under GST law.
On invoicegenerator-free.com you can quickly generate a professional PDF with line items, tax percentage, and totals — ideal for getting paid fast while you set up full GST compliance. When you need saved clients, history, and reminders, upgrade to the dashboard.
