A GST invoice lists what you sold, the tax charged on it and the total. You can make one as a PDF without any software.
Steps
- Open Invoice Generator and enter your business name, address and GSTIN, and the customer's details.
- Add each item with its quantity, rate and GST rate.
- Tick Different state if the customer is in another state. Then the tax shows as IGST.
- Check the totals, then download the PDF.
CGST, SGST or IGST?
- Selling within one state: the GST is split equally into CGST and SGST.
- Selling to another state: the whole GST is charged as IGST.
Good to know
- The total is rounded to a whole rupee, and the round off is shown.
- This tool does not give tax advice. Check your invoice details against the GST rules that apply to you.
- Your business details are saved only in your browser.
