What it does
Builds a printable tax invoice layout with line-wise taxable values and CGST+SGST (intra-state) or IGST (inter-state) based on your toggle or GSTIN state codes.
Why it matters
A clear invoice reduces disputes and supports compliant bookkeeping — but the correct tax treatment depends on your actual supply and registration.
Definition
GST in India is levied on the taxable value of supply; intra-state supplies typically split into CGST and SGST, while inter-state supplies generally attract IGST.
Assumptions

Store invoice series, originals, and credit notes in line with your compliance process.
