Free GST Invoice Generator for Indian Businesses

Quick answer

To create a GST invoice, you need your GSTIN and address, the client's details, a sequential invoice number, the date, item descriptions with HSN/SAC codes, the taxable value, and the tax shown as a separate CGST/SGST or IGST split. This tool builds all of that and downloads it as an A4 PDF — free, no signup, no watermark.

Fill in your details on the left, watch the invoice build itself on the right, and download a clean A4 PDF. That is the whole workflow. There is no signup, no email wall, no watermark and no limit on how many invoices you create. It is a free tool published by Intech Global Solutions for freelancers, consultants, shop owners and small businesses who need a professional-looking bill without paying for accounting software.

What the invoice generator does

GST-ready tax handling

Set a tax rate and it is applied across all line items with the total shown separately, so the invoice satisfies the usual GST presentation expectations.

Live A4 preview

The preview updates as you type. What you see on screen is exactly what lands in the PDF — no surprises after download.

Instant PDF download

One click produces a print-ready A4 PDF you can email to a client or file for your records. Nothing is queued or emailed to you.

Multiple currencies

Bill in rupees, dollars, pounds, euros or dirhams — useful if you invoice overseas clients alongside domestic ones.

Colour themes

Pick an accent colour or enter your own hex code so the invoice carries your brand rather than a generic template look.

Works on your phone

A dedicated mobile layout with Form and Preview tabs, so you can raise an invoice from a shop counter or a client site.

How to create an invoice

  1. Enter your business details. Name, address, email and phone go in the "Your Business" block and appear at the top of the invoice.
  2. Add the client. Fill in who you are billing under "Bill To".
  3. Set the invoice number and dates. Pick an invoice number, issue date and due date. A sequential, unbroken numbering series matters if you are GST-registered.
  4. List your items. Add a description, quantity and rate for each line. Totals recalculate as you type.
  5. Set tax and discount. Enter your GST percentage and any discount. The summary shows subtotal, tax, discount and grand total separately.
  6. Add notes and pick a colour. Payment terms and bank details go in the notes field. Choose an accent colour to match your brand.
  7. Download the PDF and send it to your client.

What a GST invoice must contain

If you are registered under GST in India, a tax invoice is a legal document and it needs specific information. Missing fields are the usual reason a client's accountant sends an invoice back, or worse, the reason they cannot claim input tax credit on it.

FieldWhy it matters
Supplier name, address & GSTINIdentifies who raised the invoice and under which registration.
Sequential invoice numberMust be unique and unbroken within a financial year. Gaps invite questions during audit.
Date of issueDetermines the tax period the supply falls into.
Recipient name, address & GSTINRequired for B2B supplies; without it the buyer cannot claim input tax credit.
Place of supplyDecides whether you charge CGST + SGST or IGST.
Description, HSN/SAC code, quantityIdentifies what was actually supplied and at what classification.
Taxable value & rateThe base amount and the percentage applied to it, shown separately.
Tax amount splitCGST, SGST/UTGST and IGST listed individually rather than as one lump sum.
SignaturePhysical or digital signature of the supplier or an authorised representative.

This tool gives you the layout and the arithmetic. You still need to enter your own GSTIN, HSN/SAC codes and place of supply in the appropriate fields — and if you are unsure which apply to your business, speak to a chartered accountant. For a fuller walkthrough, read our guide on GST invoice format, rules and common mistakes.

CGST + SGST or IGST?

The split depends on where the supply goes, not where your bank is. If the place of supply is in the same state as your registration, the tax is divided equally into CGST and SGST — 18% becomes 9% + 9%. If the supply crosses into another state, or is an export, the whole amount is charged as IGST. The total the client pays is identical either way; only the split changes. Getting it backwards means filing a correction later, so confirm the place of supply before you send the invoice.

Your data does not leave your browser

Everything you type stays on your own device. The invoice is rendered and converted to PDF locally in JavaScript — client names, amounts and bank details are never transmitted to Intech Global Solutions or stored anywhere. The flip side is that nothing is saved either: close the tab and the invoice is gone, so download the PDF before you leave.

Frequently asked questions

Is this invoice generator free?

Yes, completely. No signup, no account, no watermark, no limit on the number of invoices, and no paid tier. It is a free utility published by Intech Global Solutions.

Can I use these invoices for GST filing?

The tool produces a correctly formatted invoice document, and you can enter your GSTIN, HSN/SAC codes and place of supply in the relevant fields. It is not accounting software — it does not file returns, maintain your books or validate GSTINs. Use it to raise the invoice, and your accountant or filing software for compliance.

Where are my invoices saved?

They are not saved anywhere. Everything runs in your browser and nothing is stored on our servers or in your browser after you close the tab. Download the PDF before leaving the page, and keep your own copies for your records.

Can I add my company logo?

The invoice carries a branded header and you can set the accent colour to match your identity. If you need your own logo image embedded, contact us — we build custom invoicing and billing systems as part of our software development services.

Does it work on a mobile phone?

Yes. On small screens the tool switches to a two-tab layout — Form and Preview — with a download button fixed to the bottom of the screen. It works in any modern mobile browser.

Can I invoice international clients?

Yes. Pick your currency from the dropdown before generating. For exports of goods or services, remember that different GST rules apply — typically zero-rated with or without payment of IGST — so check your treatment with your accountant.

How the totals are calculated

Every figure on the invoice is derived from your inputs in this order, so you can reconcile it against any accounting system:

Whether that tax appears as CGST + SGST or as IGST depends on the place of supply, which you set. The arithmetic is identical either way.

Sources and further reading

GST rules, rates and thresholds are set by the Government of India and are revised periodically. This tool formats an invoice and does the arithmetic; it does not track statutory changes for you. Confirm current requirements against the official sources below or with your chartered accountant before relying on an invoice for compliance.
