Is this GST invoice generator really free?
Yes — no login, no signup, no watermark across your invoice, and no limit on how many invoices you generate.
How does it decide CGST+SGST vs IGST?
From the seller's and buyer's state you pick: the same state means CGST+SGST (split equally), a different state means a single IGST line — the standard GST place-of-supply rule.
Can different line items have different GST rates?
Yes — each line item has its own GST rate dropdown, and the invoice groups its tax summary by rate.
Does this generate an e-invoice or file anything with the GST portal?
No — this only creates a printable/downloadable invoice document. It does not generate an IRN, does not connect to the GST e-invoicing portal, and does not file anything on your behalf.
How do I download the invoice?
Tap "Print / Save as PDF" — it opens your browser's print dialog, where you can save it as a PDF or print it directly.
