GST invoice generator
Free GST Invoice Generator Online (CGST, SGST, IGST)
Small businesses and online sellers in India regularly need to issue GST invoices – for offline sales, B2B orders or website orders that are not invoiced by a marketplace.
A free GST invoice generator lets you create a correct, professional invoice in a couple of minutes, without accounting software.
How to create a GST invoice
- Open the GST invoice generator.
- Enter your business details and GSTIN – they are remembered for next time.
- Enter the buyer’s name, address, GSTIN (for B2B) and state.
- Add items with HSN/SAC code, quantity, rate and GST %.
- Print or save as PDF.
Automatic tax split
If the buyer is in your state, tax is split into CGST and SGST. If the buyer is in another state, IGST is applied. Totals and the amount in words are calculated for you.
Add your logo and keep details
You can add your business logo so invoices look professional and match your brand. Your seller details, GSTIN and logo are remembered in your browser, so the next invoice only needs the buyer and items.
Tips for clean invoices
- Use a consistent invoice number series, for example LC/2026-27/001.
- Check the buyer’s state – it decides CGST + SGST or IGST.
- Use the correct HSN code for goods or SAC for services.
- Keep a PDF copy of every invoice you issue.
What a GST invoice usually includes
- Invoice number and date.
