How to Register for GST E-Invoicing Online – Complete Process

In today’s digital tax era, GST E-Invoicing has become an essential compliance requirement for all registered businesses in India. The Government of India introduced the E-Invoicing system under GST to simplify tax reporting, reduce fraud, and ensure seamless data flow between businesses and the GST system.

If you are a business owner or tax professional looking to understand the complete process of E-Invoice registration, this detailed guide by Tax Esquire Corporate Advisors will walk you through every step — from eligibility to generation — in a simple, structured manner.

What is GST E-Invoicing?

GST E-Invoicing, or “Electronic Invoicing,” is a system under which invoices generated by a business are electronically authenticated by the Goods and Services Tax Network (GSTN). Each invoice is assigned a unique Invoice Reference Number (IRN) and a QR Code, which ensures its validity and traceability.

Unlike manual invoice uploading, E-Invoicing automates the reporting of B2B transactions to the GST portal, reducing errors and saving time for both buyers and sellers.

Who Needs to Register for GST E-Invoicing?

E-Invoicing under GST applies to businesses whose aggregate annual turnover crosses the prescribed threshold.

As per the latest update by the Central Board of Indirect Taxes and Customs (CBIC):

• Businesses with a turnover of ₹5 crore or more in any financial year from 2017-18 onwards are mandated to generate E-Invoices.
• Businesses below this limit can voluntarily opt for E-Invoicing to streamline their billing and tax filing processes.

To check whether your GST number is eligible for E-Invoicing, you can verify it on the E-Invoice enablement portal (https://einvoice.gst.gov.in).

Benefits of GST E-Invoicing

1. Error-Free Data Entry – Automatically uploads invoice details to GST returns and e-way bills.
2. Faster Input Tax Credit (ITC) – Ensures real-time availability of invoice data for buyers.
3. Improved Compliance – Reduces duplication, fake invoices, and mismatched data.
4. Transparency – Builds trust between buyers and suppliers with verified transactions.
5. Time-Saving Automation – Integrates with ERP and accounting software like Tally, Zoho Books, or RoboBooks (recommended by Tax Esquire).

Step-by-Step Process to Register for GST E-Invoicing Online

Follow these 7 simple steps to register your business on the E-Invoice Portal:

Step 1: Visit the E-Invoice Portal

Go to the official government website – https://einvoice.gst.gov.in.
Click on ‘Registration’ and then select ‘e-Invoice Enablement’.

Step 2: Login Using GSTIN

Enter your GSTIN (Goods and Services Tax Identification Number).
The system will fetch your business details such as name, registered address, and type of taxpayer.
If you are already registered on the E-Way Bill Portal, you can use the same credentials here.

Step 3: Validate Your Business Details

Verify your business details carefully. If your business is eligible based on turnover, the system will allow you to proceed with E-Invoice registration.

If not, you’ll see a message stating “You are not eligible for E-Invoicing” — in such cases, you must confirm your turnover records with your CA or consultant like Tax Esquire Corporate Advisors.

Step 4: Create a User ID and Password

Once validated, create a new User ID and password for the E-Invoice system.
These credentials will help you log in to the Invoice Registration Portal (IRP) for future invoice generation.

Step 5: Login to the IRP Portal

Use your credentials to log in to the IRP portal (https://einvoice1.gst.gov.in).
Here, you’ll find options to generate, view, cancel, or download E-Invoices.

Step 6: Choose Your Method to Generate E-Invoice

There are multiple ways to generate E-Invoices:

1. Using Accounting Software – Integrated directly with IRP (Tally, RoboBooks, Busy, Marg, etc.).
2. Using Bulk Upload Tool – For uploading multiple invoices in Excel or JSON format.
3. API Integration – For large enterprises that issue thousands of invoices daily.

Tax Esquire can help you integrate your accounting software for auto E-Invoice generation with zero errors.

Step 7: Generate and Validate E-Invoice

Once you upload the invoice data, the IRP validates it and assigns a unique IRN and QR code.
You can then print this E-Invoice or share it with your customer.

The system automatically shares this data with:

• GST Portal for GSTR-1 return
• E-Way Bill System, if applicable

That’s it — your E-Invoice registration and generation are complete!

Important Points to Remember

• Always use the latest schema and format prescribed by GSTN.
• Ensure your turnover-based eligibility before enabling E-Invoicing.
• Keep your API credentials and password secure.
• Avoid duplicate invoice uploads to prevent IRN rejections.
• If your turnover falls below ₹5 crore, E-Invoicing remains optional but beneficial.
