As mentioned in the above table, the e-invoicing system is already in place for larger businesses with a turnover exceeding 500 crores from 1st October 2020. The mandatory implementation of an e-invoicing system for all businesses with a turnover exceeding 50 crores was from 1st April 2021. 

Later, businesses with a turnover exceeding 20 crore were mandated to generate e-invoices from 1st April 2022, followed by mandating the e-invoice generation for businesses with a turnover exceeding 10 crores from 1st October 2022. In the recent update, e-invoicing will be applicable for businesses with a turnover exceeding 5crores from 1st August 2023.

The Government had considered only the largest businesses to start with the e-invoice system, and gradually, in a phased manner, more businesses are brought into the scope by reducing the turnover limit. 

Business preparedness for e-invoicing in GST

The e-invoicing functioning depends on how well the accounting software or ERP system interacts with the IRP system. This is because an invoice is valid only if it contains an IRN and QR code which is authenticated by the IRP system.

As a business, for you to sail smoothly, the accounting software you use should have a built-in capability to generate e-invoice data in the prescribed format and more importantly, seamlessly interacts with the IRP portal to complete the e-invoice process without the manual intervention. 

With e-invoicing being introduced, the first step towards preparedness is to understand the e-invoice fundamentals and get used to the system. Secondly, need to consider accounting software which will not only generate the e-invoice data but also has an online capability to interact with the IRP system to generate e-invoice.
