A game-changer into the world of invoicing to ensure interoperability of the data with various system and curb the tax evasion was proposed to be brought up during the beginning of the new financial year 1st April 2020. However, the need was felt to allow businesses to get used to the new system of e-invoice and as a result, the date of implementing the e-invoice pushed to 1st October,2020 for businesses with a turnover of 500 crores and above. 

The e-invoice system with a standardized protocol, powered by information technology, will enable machines to read electronic invoices. To give a brief, e-invoicing is a system in which B2B invoices are authenticated electronically by Invoice Register Portal (IRP)

The concept of e-invoice begins with the validation of invoice data uploaded by the taxpayer and issuing a unique identification number called as 'Invoice Registration Number (IRN)' for every invoice being uploaded into the system. A QR code is tagged against every invoice for further use by various Government portals, tax officials and taxpayers.

The GST Council has approved the introduction of e-invoicing in a phased manner for reporting of business – to - business (B2B) invoices to the GST System. This will be introduced based on turnover criteria as detailed below:

500 Crore & above

1st October, 2020

100 Crore up to 500 crore

1st January,2021

As mentioned in the above table, the e-invoicing system is already in place for larger businesses with turnover up to 500 crores from 1st October, 2020. The mandatory implementation of e-invoicing system for all the businesses with a turnover of 100 crores and above is from 1st January,2021. 

The Government has considered only the larger businesses to start with the e-invoice system and gradually, in a phased manner, more number of businesses will be brought into the ambit by reducing the turnover limit. It is expected that e-invoice will be implemented from April,2021 for the rest of businesses. 

Business preparedness for e-Invoicing in GST

The e-invoicing functioning will depend 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.
