What is a GST Invoice?

A GST invoice (or tax invoice) is a legal document issued by a GST-registered supplier to a buyer. It must include the supplier's GSTIN, HSN/SAC codes, item-wise GST rates, and the breakdown of CGST, SGST, and IGST. Businesses with annual turnover above ₹40 lakh (₹20 lakh for services) must issue GST invoices.

Frequently Asked Questions

Is this GST invoice generator completely free?
Yes, this tool is 100% free with no hidden charges, no signup, and no subscription required.
What is the difference between CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) are applied on intra-state sales — each is half of the total GST rate. IGST (Integrated GST) applies on inter-state sales and equals the full GST rate. This tool detects which applies based on supplier and buyer states.
Can I add multiple items with different GST rates?
Yes. Each line item in the invoice can have its own GST rate — 0%, 5%, 12%, 18%, or 28%.
Can I add my business logo and signature?
Yes. You can upload your business logo and digital signature, which will appear on the generated invoice.
Is my data safe? Does it get stored on any server?
No. All invoice data is processed entirely in your browser. Nothing is sent to any server. Saved invoices are stored locally in your browser's localStorage.
What is HSN and SAC code in GST invoices?
HSN (Harmonized System of Nomenclature) codes classify goods. SAC (Service Accounting Code) codes classify services. Businesses with turnover above ₹5 crore must mention 6-digit HSN/SAC codes on invoices.
