User Guide for E-Invoice Feature

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.

Assist Biz now provides an e-Invoicing feature designed to seamlessly integrate with Malaysia’s GoFT regulations, making it easy for businesses to manage invoices while staying fully compliant.
