FAQ

Is this really free?

Yes. The invoice generator is free forever, with no limits. We'll make money from the optional Pro plan (recurring invoices, payment reminders, GST reports).

Is my data safe?

Your invoice data never leaves your browser — it's stored in your device's local storage only. We have no database of your invoices.

How is GST calculated?

If your state and the place of supply are the same, GST is split into CGST + SGST. If different, IGST applies. You set the GST rate per line item (0, 5, 12, 18 or 28%).

Do I need a GSTIN to use this?

No. If you're not GST-registered, leave the GSTIN blank and set GST rates to 0 — you'll get a clean professional invoice without tax lines.
