What a GST tax invoice must show

Rule 46 of the CGST Rules, 2017 lists the particulars. The generator asks for each one that applies to an ordinary invoice.

Supplier and recipient

Both parties' names, addresses and GSTINs.

Read more about Supplier and recipient

Name, address and GSTIN of the supplier, and the name, address and GSTIN of the recipient if registered. For an unregistered recipient, the name, address and state are needed when the taxable value is ₹50,000 or more.

Invoice number and date

Up to 16 characters, unique in the financial year.

A consecutive serial number of up to 16 characters, using letters, numerals, hyphen and slash, unique for the financial year. Many businesses use a series such as INV/2026-27/001.

HSN or SAC, description and quantity

4 digits up to ₹5 crore turnover, 6 above.

Read more about HSN or SAC, description and quantity

The HSN code for goods or SAC for services, a description, and the quantity with its unit. From 1 April 2021, businesses with turnover up to ₹5 crore show 4 digits and those above show 6. Businesses up to ₹5 crore may leave HSN off supplies to unregistered customers.

Values, rates and tax amounts

Taxable value, each tax's rate and amount, and the total.

The taxable value after any discount, the rate and amount of each tax (CGST and SGST or UTGST within a state, IGST between states), and the total value.

Place of supply and delivery address

Place of supply with the state, and the delivery address if different.

Read more about Place of supply and delivery address

For an inter-state supply, the place of supply with the name of the state. If goods go somewhere other than the place of supply, the delivery address too.

Reverse charge and signature

Reverse charge yes or no, and a signature.

Read more about Reverse charge and signature

Whether tax is payable on reverse charge, and the signature or digital signature of the supplier or an authorised person. Under the rule's proviso, an invoice issued electronically under the IT Act, 2000 does not need a signature.

When you need an e-invoice instead

Above ₹5 crore turnover, B2B invoices need an IRN from the Invoice Registration Portal.

Businesses with aggregate turnover above ₹5 crore in any financial year since 2017-18 must report their B2B invoices to the Invoice Registration Portal, which returns an IRN and a QR code that go on the invoice. This generator does not do that and does not make e-way bills. Since 1 April 2025, businesses with turnover of ₹10 crore and above cannot report an invoice older than 30 days to the portal.

Sources: Rule 46, CGST Rules 2017 (CBIC), Notification 78/2020 Central Tax on HSN digits, e-invoice portal. Checked on 12 November 2026. Rules change: confirm with your CA before relying on a format.

Invoicing every month

For regular invoicing, numbering, bank matching and GST summaries, use Fint.

Read more about Invoicing every month

A generator is fine for an occasional invoice. If you raise invoices every week, you also need the numbering kept for you, quotes that turn into invoices, payments matched to the bank, and GSTR-1 and GSTR-3B figures at month end. That is what Fint does, free while it is in beta, with an AI agent that drafts records for a person to confirm. If you already work in Tally, see Fint vs TallyPrime. To check a single figure, use the GST calculator.

Questions

Is this GST invoice generator free?

Yes. There is no sign-up and no limit. It runs entirely in your browser; nothing you type is sent to us or anyone else.

How does it choose between CGST and SGST or IGST?

It compares the state in your GSTIN (the first two digits) with the place of supply. Same state: CGST and SGST, or UTGST in a union territory without a legislature. Different states: IGST.

How do I save the invoice as a PDF?

Press Print or save as PDF. The invoice opens in a new tab and the print window appears; choose Save as PDF as the printer. If nothing opens, allow pop-ups for this site.

Does it check my GSTIN?

It checks the format, the state code and the check character at the end, which catches most typing mistakes. It does not look the GSTIN up on the GST portal, so it cannot tell whether a registration is active.

Does it make e-invoices or e-way bills?

No. Businesses with aggregate turnover above ₹5 crore must get an IRN for B2B invoices from the Invoice Registration Portal, and e-way bills come from the e-way bill system.
