Worth knowing

  • GST Invoice Generator on Toolspire: makes tax invoices, bills of supply, proforma invoices and quotations as a ready-to-send A4 PDF with real, searchable text.
  • Charges CGST + SGST when the place of supply is in your state and IGST when it isn’t — per item, rounded to the paisa, with an HSN/SAC-wise tax summary.
  • Checks GSTINs (format, state code and check digit) and fills in the state and PAN from them.
  • Adds a UPI QR code for the exact amount, your bank details, logo, signature, the amount in words and an optional original, duplicate and triplicate set.
  • Handles discounts, GST-inclusive prices, round-off and numbering (INV-007 → INV-008). Long item lists continue onto more pages.
  • Works offline once loaded: your business details, customers and the last invoice are saved only in this browser, with a backup file you can keep.

What a GST tax invoice must show

  • Your name, address and GSTIN, and a unique invoice number (up to 16 characters) and date.
  • The buyer’s name and address, and their GSTIN if they are registered.
  • The place of supply (state name and code), for supplies between states.
  • For each item: description, HSN or SAC code, quantity and unit, value, discount and the taxable value.
  • The GST rate and amount — CGST and SGST, or IGST — and the invoice total.
  • Whether tax is payable on reverse charge, and the signature of the supplier or an authorised person.

FAQ

Questions about GST Invoice Generator

Where does GST Invoice Generator run?

GST Invoice Generator runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

Is this GST invoice generator free?

Yes — free, with no account, no watermark and no limit on invoices.

Does it work offline?

Yes. Once the page has loaded, invoices are made entirely in this tab, so you can keep working without internet. Your details are saved on this device only.

When is IGST charged instead of CGST and SGST?

When the place of supply is in a different state from yours. Within your state, the GST rate is split equally into CGST and SGST. The invoice switches automatically when you choose the customer’s state.

What is a bill of supply?

An invoice without GST, issued by composition dealers or for exempt goods and services. Choose Bill of Supply and no tax is charged or shown.

Can I add a UPI QR code to the invoice?

Yes. Enter your UPI ID under Payment; the PDF gets a QR code for the exact invoice amount that any UPI app can scan.

Is my data safe?

Nothing is uploaded. Your business details, customers and invoices stay in this browser — download a backup file to move them to another device.

Does it make e-invoices with an IRN?

No. E-invoicing (IRN and QR from the government portal) is required only above a turnover limit and needs the IRP portal. This tool makes regular GST invoices.
