Starter’s Guide to e-Invoicing Under GST


In the digital world, invoicing is generated by the software. The invoice which is generated by the software is known as e-invoicing.

The companies include the GST in their invoices. The transportation of goods or materials generates the ‘e-way bills’ through the common GST portal. In the market, there are various accounting software and systems available which help companies or businesses to generate e-invoicing under GST.

E-invoicing provides several benefits to businesses. The businesses easily create the invoice and without any errors.

The business can easily save the invoice and keep the previous invoice in the database. So when they need an invoice, then the sales team or marketing team of the companies can easily find the invoices.

E-Invoicing under GST

The ‘electronic bill’ is another name for e-invoicing. GST invoices differ from regular invoices in several ways. As a result, when businesses issued GST invoices, the IRP (Invoice Registration Portal), which is controlled by the GST Network, supplied them with an identifying number (GSTN).

When the companies create the normal or physical bill then they have to do the manual entry in the GST portal. But, when the companies create the e-invoice then the information will be transformed into both the GST portal and e-way bill portal that’s why they need to do the manual entry during the filing of GSTR-1 returns. Through the help of e-invoicing, the information is passed through the IRP to the GST portal.

The e-invoicing was introduced on 1st October 2020 for the taxpayers with an aggregate turnover RS. 500 crore. Then the e-invoicing was extended to the companies with an aggregated turnover RS. 100 crore on 1st January 2021.

From the 1st April 2021, CBIC notified that e-invoice will apply in the business with an aggregated turnover of more than RS.50 crore. The companies have the specified limit of turnover at the 2017-18 to 2019-20 financial year that is applicable for generating the e-invoicing under GST. Here, an aggregate turnover of all GSTINs will be registered under a single PAN across India.

Some businesses or companies used the facked invoices to avoid paying the taxes. Through this, the government prevents various serious problems. That’s why the government introduced the mechanism for e-invoicing to reduce fraud.

Currently, how are the businesses issuing invoices?
