The preview of the e-invoice is not showing my customized format. Why is this happening?
E-Invoice printing is only available in the default format provided by the E-Invoice portal. It is not possible to print E-Invoices in a customized format.
If you wish to include E-Invoice IRN/Ack.No./Ack.Date in your customized format, you can add the field for E-Invoice QR Code or IRN No.etc.
