Use the free tool here: https://saraltools.in/gst-invoice-generator/ ## What a GST invoice must contain Under Rule 46 of the CGST Rules, a tax invoice should include: - Name, address and GSTIN of the supplier - A unique, consecutive invoice number (up to 16 characters) and the date - Name, address and GSTIN (if registered) of the recipient - Place of supply and state, for interstate sales - HSN code for goods or SAC code for services - Description, quantity, unit and taxable value of each item - Rate and amount of CGST, SGST/UTGST or IGST - Signature of the supplier or an authorised person This generator lays all of these out in a clean A4 format. ## CGST + SGST or IGST? Pick your state and the place of supply. If they are the same, the invoice splits tax equally into CGST and SGST. If they are different, it charges IGST. You can double-check any amount with the [GST calculator](https://saraltools.in/gst-calculator/). ## Get paid faster with a UPI QR Add your UPI ID and the invoice shows a QR code with the exact amount and invoice number filled in. Your customer scans it with any UPI app (PhonePe, Google Pay, Paytm or their bank app) and pays in seconds. ## Need a price quote first? Send a [quotation](https://saraltools.in/quotation-generator/) before the job, then turn it into an invoice here when the work is done. ## Frequently asked questions ### Is this GST invoice format valid? It includes the details required by GST invoice rules: supplier name, address and GSTIN, invoice number and date, customer details (and GSTIN for B2B), place of supply, HSN/SAC, quantity, taxable value, tax rate and amount split into CGST/SGST or IGST, and the total in words. Check that your HSN codes and rates are correct for your goods. ### Do I need e-invoicing instead? E-invoicing through the IRP is mandatory for businesses with aggregate turnover above ₹5 crore. Smaller businesses can use a normal invoice like this one. ### Can I make an invoice without GST? Yes. Untick 'I am GST registered' and the tool creates a simple invoice without GSTIN or tax columns, which is right for businesses that are not registered for GST. ### Is my business data saved?
