Introduction
As a transformative shift, authorities worldwide are understanding the impact of e-invoicing on the functioning of tax administration, including Malaysia’s IRBM. As the benefits of e-invoicing are not a secret anymore, neither for authorities nor for business organizations, it is equally crucial to understand and work on key prerequisites and assess an organization’s readiness for implementing e-invoicing in the business process.
This pre-requisite and readiness assessment involves legal and regulatory compliance, technical infrastructure, and comprehensive training. By addressing these pre-requisites, businesses can have a seamless transition to e-invoicing, adding operational efficiency and accuracy and fostering sustainable business workflow.
This article will take to the prerequisites for the implementation of e-invoicing.
