Businesses above the e-invoicing turnover limit must generate e-invoices on the government portal. This tool is meant for freelancers and small businesses below that limit.
Questions people ask
When do I charge CGST and SGST, and when IGST?
If you and your client are in the same state, split the GST equally into CGST and SGST. If the client is in another state, charge the full rate as IGST. This generator decides automatically from the two states.
What GST rate applies to freelance services?
Most professional and IT services are taxed at 18%. Since September 2025 the main GST rates are 5% and 18%, with 40% for a few luxury and sin goods. Check the rate for your exact service or product.
Do I need GST registration?
Service providers generally need to register once their yearly turnover crosses ₹20 lakh (₹10 lakh in some states), and anyone exporting services or selling across states may need to register earlier. If you aren’t registered, issue a bill of supply without GST instead.
Is my data saved?
Your invoice is built in your browser. If you tick "remember my details", your own business details are saved only in this browser so you don’t retype them. Nothing is sent to us.
