Frequently asked questions
Is this invoice generator really free?
Yes. There is no signup, no watermark and no limit on the number of invoices.
Where is my invoice data stored?
Only in your browser on this device. Nothing is uploaded to any server. A different browser or device starts empty, so keep using the same browser for your invoices.
Is the invoice GST-compliant?
It prints the fields a tax invoice needs under Rule 46 of the CGST Rules: supplier and recipient GSTIN, a unique invoice number per financial year, date, place of supply, HSN/SAC codes, taxable value, rate-wise CGST/SGST or IGST, the reverse-charge declaration and the amount in words. It also checks GSTINs for typos before issuing.
What is the difference between CGST, SGST and IGST?
If the supplier and the place of supply are in the same state, the GST is split equally into CGST (central) and SGST (state), for example 9% + 9% for an 18% item. If they are in different states, the full rate is charged as IGST, for example 18% IGST. The generator picks the right one from the GSTINs and the place of supply.
What should a GST invoice number look like?
It must be a consecutive serial number of up to 16 characters, using letters, digits, hyphens or slashes, and unique for each financial year (April to March). This tool numbers invoices like AXIS/26-27/A0014 and starts a new series every 1 April.
Do I need HSN or SAC codes on my invoice?
HSN codes (goods) and SAC codes (services) are required on B2B tax invoices: at least 4 digits if your annual turnover is up to ₹5 crore, and 6 digits above that. You can add them per item in the HSN/SAC column.
I am not GST-registered. Can I still use it?
Yes. Leave the GSTIN empty and set Tax to "No tax". You get a clean invoice without GST lines.
Can I make export invoices or invoices under LUT?
Yes. Choose "Export under LUT (0%)" or "SEZ under LUT (0%)" as the supply type and the invoice is zero-rated with the required LUT declaration. Exports with IGST payment are supported too.
What is reverse charge and how is it shown?
Under reverse charge the recipient pays the GST to the government instead of the supplier. Tick "Reverse charge" and the invoice shows the tax amount, states "Tax payable on reverse charge: Yes", and the total you collect is the taxable value only.
Does it generate e-invoices (IRN)?
No. Businesses with annual turnover above ₹5 crore must report B2B invoices to the Invoice Registration Portal to get an IRN and QR code. This tool creates regular PDF tax invoices and does not connect to the portal.
How do I download the invoice as a PDF?
Click "Issue & download PDF", then choose "Save as PDF" in the print window. On iPhone: Share → Print → pinch out on the preview → Share → Save to Files.
Can my client pay directly from the invoice?
Add your UPI ID once and every invoice carries a scan-to-pay QR code for the exact amount, which opens in GPay, PhonePe, Paytm or any UPI app.
Does it work on mobile?
Yes, it runs in any modern mobile browser. Editing is more comfortable on a tablet or computer because the invoice is A4-sized.
