Anatomy of a GST invoice

Everything that belongs on the page, and where it goes.

How GST is split on an invoice

The split depends on where the supply takes place. When the supplier’s state and the place of supply are the same, the supply is intra-state and tax is divided equally into CGST and SGST. When they differ, it is inter-state and the full rate is charged as IGST.

This generator compares the two states you choose and applies the right treatment to every line. An 18% item within Karnataka shows 9% CGST and 9% SGST, while the same item sold into Maharashtra shows 18% IGST.

This tool creates the invoice document only. Businesses covered by e-invoicing must also report invoices to the Invoice Registration Portal to get an IRN, which this tool does not do. Check the rules that apply to you with your accountant.

Make every GST invoice automatic

This request creates the document in the form above, and it updates as you type. Connect it to your app or order system and each GST invoice makes itself.

Questions, answered

The things people usually ask before they download.

When should I charge IGST instead of CGST and SGST?

Charge IGST when the supplier’s state and the place of supply are different. Charge CGST and SGST when they are the same. Pick the two states in the form and the invoice follows automatically.

Does this generator create an e-invoice with an IRN and QR code?

No. It creates a GST tax invoice as a PDF. If your business is covered by e-invoicing, you also need to register each invoice on the Invoice Registration Portal.

Can I invoice an unregistered customer?

Yes. Leave the customer GSTIN blank and the invoice shows only their state.

Are the GST rates filled in for me?

No. Enter the rate that applies to each item, because rates depend on the HSN or SAC code and change from time to time. Confirm yours with the official GST rate schedules or your accountant.

Is this GST invoice generator really free?

Yes. You can create up to 10 PDFs a day without an account or a credit card.

Will there be a watermark on my PDF?

No. Your document stays clean, with one small “Made with PDFgen” line at the foot of each page.

Do you store what I enter?

No. Your details are sent to our server to create the PDF and are not saved. The form lives in your browser, so copy anything you want to keep before leaving the page.

Can I create GST invoices automatically?

Yes. The API call further up this page produces the same GST invoice from your own data, so your app or order system can create them without anyone filling in a form.
