Before let’s understand what e-invoicing really is.

What is e-Invoicing under GST Rule?

Prior to the introduction of-Invoicing term under GST rule bill generated digitally using a computer was considered as e-invoice.

However, in the context of the Goods and Services Tax (GST) regime, ‘e-Invoicing’ or ‘electronic invoicing’ refers to a system introduced by the government for the authentication of B2B invoices and certain other documents through the GST portal.

e-Invoicing is not about creating invoices directly on the GST portal. Instead, it involves submitting invoices that have already been generated in a standard format on a common e-invoice portal. This process helps automate various reporting requirements by entering invoice details just once.

In this electronic invoicing system, each invoice is assigned a unique identification number by the Invoice Registration Portal (IRP), which is managed by the GST Network (GSTN).

The information from these invoices is automatically transferred in real-time from the IRP to both the GST portal and the e-way bill portal. So taxpayers don’t need to manually fill details when filing GSTR-1 returns and generating part-A of e-way bills.

e-Invoicing Limit Over the Time

e-Invoicing Limit Over the Time

The implementation of e-invoicing under the Goods and Services Tax (GST) regime has witnessed a gradual expansion of its scope and applicability over time. Initially, when e-invoicing was introduced, it had a prescribed turnover threshold of business with turnover greater than 500 crore to generate electronic invoices.

However, as the system evolved and gained acceptance, the turnover limit for e-invoicing has been periodically revised and expanded to cover a larger segment of businesses. Now even the smaller businesses are covered under the e-invoicing rule in GST.

Here is a Table showing e-invoicing turnover limit applicable to different segments over time.

Applicability Datee-Invoicing Turnover Limit
01.08.2023Rs 5 crore
01.10.2022Rs 10 crore
01.04.2022Rs 20 crore
01.04.2021Rs 50 crore
01.01.2021Rs 100 crore
01.10.2020Rs 500 crore

In future, there is a that the limit for e-invoicing will come further down.

Starting from 1st August 2023, it is mandatory for businesses that have an annual aggregate turnover of over Rs.5 crore in any previous financial year from 2017-18 to implement e-invoicing.


Let’s say there is a company called XYZ Pvt. Ltd. that has been operating since 2015 and has seen inconsistent growth in its business. Their annual turnover over the year has been as follows.

2017-183.5 Cr
2018-194 Cr
2019-206 Cr
2020-214.75 Cr
2021-224.8 Cr
2022-233.5 Cr

Even though XYZ’s annual turnover in part 3 years is less than 5 cr, since the business has exceeded the threshold limit of 5 Crore in financial year.

Reasons for e-Invoicing

The e-invoicing system brings several advantages for businesses and especially the Government. Here are the key benefits explained in simple terms:

  • 1. Simplified Reporting: With e-invoicing, you don’t have to enter the same invoice details multiple times in different forms. Just upload it once, and the required information will automatically populate in various returns and documents.
  • 2. Easy e-Way Bill Generation: The system captures the necessary information from the invoice, making it easier to generate part-A of the e-way bill. You only need to update the transporter details.
  • 3. Automatic GSTR-1 Filing: By uploading invoices, the system automatically captures the business-to-business (B2B) details and includes them in the GSTR-1 return. This simplifies the process of reporting sales to the tax department.
  • 4. Smooth Input Credit Verification: The e-invoice data reported to the tax department also appears in the buyer’s inward supply register (GSTR-2A). This reduces challenges in verifying input credit, streamlining the process for businesses.
  • 5. Reconciliation Made Easier: The buyer can reconcile the invoice data received from the GST system with their purchase register. This helps with timely acceptance or rejection of the information during the new return filing process.
  • 6. Curbing Tax Evasion: The e-invoice system maintains a complete trail of business-to-business invoices, allowing for system-level matching of input credit and output tax. This helps in reducing instances of tax evasion.

How to Generate e-Invoice?

Here are the steps to generate e-invoices.

  • 1. Invoice Creation: Use accounting or billing software to create invoices in the prescribed e-invoicing format. It is not mandatory to use the government’s tax portal for generating e-invoices.
  • 2. Invoice Registration Number (IRN) Generation: Suppliers can optionally generate a unique Invoice Reference Number (IRN) using a hash-generation algorithm. If not generated, the government’s IRP system will generate it.
  • 3. Upload on Invoice Registration Portal (IRP): Upload the JSON file of each B2B invoice, along with the IRN if generated, on the Invoice Registration Portal (IRP).
  • 4. IRP Validation of Invoice Information: The IRP validates the uploaded invoice against the central GST registry, ensuring uniqueness and authenticity. A digital signature and QR code are added to the invoice.
  • 5. Digital Signature and QR Code Generation: The IRP digitally signs the invoice and adds a QR code to the JSON file.
  • 6. E-Invoice Data Transmission: The validated invoice data is shared with the E-way bill and GST system for auto-population of GST Annexures.
  • 7. E-Invoice Receipt: The digitally signed JSON file with IRN and QR code is sent back to the seller’s ERP system. The invoice is also emailed to the buyer.
