Everything between raising the invoice and receiving the payment

Tax that is right by default

Pick the customer and the place of supply decides CGST and SGST or IGST. HSN and SAC codes, rates and round-off come from the item, so the invoice is correct before you look at it.

  • GSTIN lookup fills customer details
  • HSN and SAC search built in
  • Custom fields and numbering per document
