What is E-invoice?
An e-Invoice is a digital record of a transaction between a supplier and a buyer, validated in real time. It includes details like seller and buyer information, item descriptions, prices, taxes, and total amounts, with unique identification for verification. Many countries, including Malaysia, have implemented e-Invoicing as part of their regulatory framework to improve transparency and compliance.
