Frequently Asked Questions

Is this GST Invoice Generator really free?
Yes. All 15 templates, unlimited invoices, PDF export and every customization option are 100% free with no sign-up, watermark, or hidden limits.
How does CGST/SGST vs IGST get decided?
The tool compares your Seller State (Step 2) with the Buyer State (Step 4). If they match, tax is split equally into CGST and SGST. If they differ, the full GST amount is charged as IGST — exactly how GST law works for goods and services within India.
Can I use this for a GSTIN-less customer (B2C)?
Yes — simply leave the Customer GSTIN field blank. The invoice will still calculate tax correctly based on the selected states.
Can I reuse my business details for future invoices?
Yes — use "Save Draft" to store your current invoice (including logo and settings) in your browser, then "Load Draft" next time to continue from where you left off.
Will the PDF look the same as the preview?
Yes — the PDF is generated directly from the live preview, so fonts, colors, logo and layout are captured exactly as shown, formatted to fit an A4 page (splitting across pages automatically if the item list is long).
Is my data private?
Completely. Nothing you type or upload is sent to a server — everything is processed and rendered locally using JavaScript in your own browser tab.
