Frequently Asked Questions about GST Invoice Generator
Is this GST invoice legally valid?
The invoice follows the format prescribed under GST rules. However, for legal compliance, ensure your GSTIN is valid and all mandatory fields are filled correctly.
How does CGST/SGST vs IGST work?
If seller and buyer are in the same state, CGST + SGST apply (split equally). If different states, IGST applies (full rate). Our tool detects this automatically.
What are HSN and SAC codes?
HSN (Harmonized System of Nomenclature) codes are for goods, SAC (Services Accounting Codes) are for services. They classify items for GST purposes.
Can I add multiple items with different tax rates?
Yes, each line item can have its own GST rate — 0%, 5%, 12%, 18%, or 28%.
Is my business data safe?
Yes, all data is processed entirely in your browser. Nothing is sent to any server.
Can I include bank details on the invoice?
Yes, you can add bank name, account number, and IFSC code which will appear on the PDF.
