How is GST calculated on an invoice?
Multiply the taxable value by the GST rate. For ₹1,000 at an example rate of 18%:
- Within a state: CGST ₹90 and SGST ₹90, making a total of ₹1,180.
- Between states: IGST ₹180, making a total of ₹1,180.
- The 18% is only an example. Use the rate that applies to what you sell.
What should a GST invoice include?
These are the main items listed in Rule 46 of the CGST Rules:

Frequently asked questions
Is this invoice generator really free?
Yes. It is free, with no sign-up, no watermark and no limit on how many invoices you make. You may use the invoices in your business.
Does Criza Labs see or store my invoices?
No. The invoice is made in your browser, and what you type is not sent to us. We cannot recover an invoice for you, so please save a copy of each one.
How do I save the invoice as a PDF?
Select Save as PDF or print, then choose Save as PDF in your browser's print window. This works on computers and most phones. The exact wording of the option depends on your browser.
Which GST rate should I use?
We do not suggest rates, because the right one depends on what you sell and rates can change. Check the official GST sources or ask a tax professional, then enter that rate for each item.
Will this meet GST rules for my business?
The tool includes fields for the main items in Rule 46, but we cannot confirm that a particular invoice is correct for your business. You are responsible for the details, and a tax professional can check your format if you are unsure.
Does it create e-invoices with an IRN?
No. It makes an ordinary PDF and does not connect to the government's e-invoicing system. If your business must issue e-invoices, you need to use that process as well.
How does the UPI QR code work?
It holds your UPI ID and the invoice total, so a customer can scan it with a UPI app and check the amount before paying. Some apps may treat these codes differently, so pay yourself a small amount to test it before you rely on it.
What does the GSTIN check tell me?
It checks the format and the check digit, which catches most typing mistakes. It does not show that a number is registered or active, which you can confirm on the GST portal.
