Is this GST invoice generator really free?

Yes. You can create and download unlimited invoices without signing up or paying. Everything runs in your browser, so there is no account to create and no limit on downloads.

Do I need a GSTIN to raise an invoice?

Only GST-registered businesses can issue a tax invoice with GST. If you are not registered, leave the GSTIN blank, set every line to 0% and issue it as a simple bill of supply.

When do I use CGST + SGST instead of IGST?

Use CGST + SGST when the place of supply is in your own state — the GST splits into two equal halves. Use IGST when the place of supply is another state or union territory, or for exports.

Where is my invoice data stored?

On your device only. The invoice, PDF and UPI QR are all generated in your browser. If you tick 'Save business details on this device', your business, payment and logo details plus the last invoice number are kept in this browser's local storage, and you can clear them any time.

Can I change the invoice design?

Pick Classic, Modern or Minimal above the preview. Only the layout changes — the items, GST breakdown and totals are calculated the same way in every template, and the PDF matches the template you selected.

How is the round off calculated?

The taxable value plus GST is rounded to the nearest rupee, as permitted under Section 170 of the CGST Act. The difference is shown separately as Round Off so your invoice always adds up.

Q: Can I add my logo, bank details and a UPI QR code?

Yes. Upload a PNG or JPG logo, fill in the optional payment section, and switch on 'Show UPI QR on invoice'. The QR encodes your UPI ID, business name and the exact payable amount, and it is drawn into both the preview and the PDF.

Fill in your business and customer details, add your items with HSN/SAC codes and GST rates, and download a clean A4 tax invoice as a PDF. CGST, SGST, IGST, discounts, round off and the amount in words are all worked out for you.

How to create a GST invoice

1. Add your business details. Legal name, address and GSTIN as registered. Upload a logo if you have one.
2. Add the customer. Tick "Customer is GST registered" and enter their GSTIN so they can claim input tax credit.
3. Set the invoice number and dates. Keep a single continuous series per financial year — we suggest the next number for you.
4. Add line items. Description, HSN or SAC code, quantity, rate, any discount and the GST rate for that item.
5. Choose CGST + SGST or IGST based on the place of supply, then check the summary.
6. Download the PDF or print it. Share it with your customer over email or WhatsApp.

GST invoice requirements

Rule 46 of the CGST Rules lists what a tax invoice must carry. The generator above includes each of these fields:

Supplier name, address and GSTIN
A consecutive invoice number (up to 16 characters) and the date of issue
Customer name, address and GSTIN where registered
HSN code for goods or SAC code for services
Description, quantity, unit rate, discount and taxable value per item
Rate and amount of CGST, SGST or IGST
Place of supply, total invoice value and the amount in words

CGST vs SGST vs IGST

CGST is the central share and SGST the state share of tax on an intra-state supply. At 18%, each is 9%, and together they equal the full GST.

IGST applies when the supplier and the place of supply are in different states or union territories. The full rate goes on one IGST line, and the Centre later shares it with the destination state.

Need only the tax on a single amount? Use the GST calculator.

GST invoice example

A Pune agency bills a Pune client for 10 hours of design at ₹1,000 per hour at 18% GST:

Taxable amount: ₹10,000.00
CGST 9%: ₹900.00
SGST 9%: ₹900.00
Grand total: ₹11,800.00
In words: Rupees Eleven Thousand Eight Hundred Only

Bill the same work to a Bengaluru client and the ₹1,800 appears as a single IGST line instead. To check that your rate still leaves a healthy profit, try the profit calculator, the margin & markup calculator or the discount calculator.

Sending an estimate before the job starts? Use the quotation generator and convert it into an invoice once the work is approved.
