How do I create a GST invoice online for free?

Enter your business and customer details with GSTINs, add line items with HSN or SAC codes, quantity, rate and GST rate, and the tool computes CGST and SGST (or IGST for inter-state supply), the grand total and the amount in words. Then download a print-ready PDF — no login, no watermark.

When is CGST/SGST charged and when is IGST charged?

If the place of supply is in the same state as your business, the GST splits into CGST and SGST. If the place of supply is a different state, a single IGST is charged instead. This tool decides automatically from the states you select.

Is an HSN code mandatory on a GST invoice?

An HSN code for goods (or SAC for services) is required on GST invoices, with the number of digits depending on turnover. Add the correct HSN/SAC for each line item so the invoice is compliant.

How it works

Fill in your business and customer details, pick your state and the place of supply, then add each item with its HSN/SAC code, quantity, rate and GST rate. If the place of supply is your own state, GST is split into CGST and SGST; if it's another state, a single IGST applies — the tool decides automatically. The taxable value, tax, grand total and amount in words are all computed for you, ready to download as a PDF.

Everything runs in your browser — nothing is uploaded and there's no watermark. Use correct HSN/SAC codes and GST rates for a compliant invoice, and confirm your GSTIN details before issuing.

Frequently asked questions

What GST rate should I use?

Use the rate notified for your goods or service — commonly 0%, 5%, 12%, 18% or 28%. You can set a different rate per line item.

Do I need the customer's GSTIN?

For B2B sales to a registered buyer, yes. For B2C sales to an unregistered customer, leave it blank — the invoice is still valid.

Can I just compute GST on an amount?

Yes — for a quick add/remove-GST calculation use the GST calculator. This tool is for producing the full invoice document.
