An e-Invoice is a digital record of a transactional exchange between a seller (supplier) and a purchaser (buyer), which goes through Inner Revenue Board of Malaysia (IRBM) MyInvois System for validation and recordkeeping.
E-Invoice contains all the details of an invoice along with a Unique Identification Number (UIN), that is generated by the government system after proper verification of the core fields like Business Registration Number, Tax Identification Number, Individual Identity Number, etc. and QR code, which enables online validation of the e-Invoice.
