How to Generate GST-Compliant Invoices for Free in India

July 2026 ยท 11 min read ยท By Prabhash Kumar

If you are a freelancer, independent consultant, or small business owner in India, billing your clients professionally is essential. Under Indian tax laws, invoices must contain specific details to be GST-compliant, such as GSTIN numbers, state codes, HSNSAC codes, and separate CGST/SGST/IGST tax breakdowns.

In this guide, we will show you how to generate professional, printable, and fully compliant GST invoices online for free.

What Makes an Invoice GST-Compliant in India?

To comply with the Central Board of Indirect Taxes and Customs (CBIC) rules, your invoice must clearly state:

  • Seller & Buyer Details: Full legal names, addresses, and GSTINs (if registered).
  • Invoice Number & Date: A unique consecutive serial number for the financial year.
  • Place of Supply: The state name (vital to determine CGST/SGST vs IGST).
  • HSN or SAC Codes: Harmonised System of Nomenclature for goods, or Services Accounting Codes for services.
  • Tax Breakdown: Split CGST (Central Tax) and SGST (State Tax) for intra-state supply, or IGST (Integrated Tax) for inter-state supply.

How to Generate Your Invoice Client-Side

Rather than using offline word processors or sharing your financial figures with cloud-based invoicing apps, you can use browser-based tools:

  1. Navigate to the **PDF Invoice Generator** under our Business category (to be added in Phase 3).
  2. Fill in your business details, client details, and transaction items.
  3. Specify HSN/SAC codes and tax rates (typically 18% for most services in India).
  4. The tool automatically computes the GST splits and total invoice value locally.
  5. Click "Download PDF" to save a clean, print-ready document directly.

Why Local Processing Matters

Your client records, billing values, and personal PAN/GSTIN details should remain secure. By using client-side tools like VisualizeMyData, all calculation and PDF formatting occur on your device memory. No database logs are created, maintaining complete business privacy.
