Financial Year is derived from order date (India): Apr 1 → Mar 31.
Inter‑state ⇒ IGST. Intra‑state (seller state = place of supply) ⇒ CGST + SGST split equally.
Tax rate defaults to 18% unless a line item tax rate is found in CSV.
Downloads a single multi‑page PDF (one invoice per page). You can also preview the first invoice.
