What is E-Invoicing?

E-Invoicing, or Electronic Invoicing, is a digital system introduced by the Government of India under the Goods and Services Tax (GST) framework to streamline the way businesses issue and manage invoices. 

Unlike traditional invoices generated in paper or PDF format, an e-invoice is created electronically and authenticated in real time by the Invoice Registration Portal (IRP) managed by the National Informatics Centre (NIC).

Under this framework, every eligible B2B invoice must be uploaded to the IRP, which verifies the data and assigns a unique Invoice Reference Number (IRN). Once validated, the system digitally signs the invoice and generates a Quick Response (QR) code containing essential transaction details. 

This digitally authenticated invoice can then be shared with buyers and reported directly to the GST and e-Way Bill systems without any manual intervention.

Essentially, e-invoicing is not about creating invoices on a government website; rather, it ensures that the invoices generated through business accounting software (like Tally Prime) comply with the government’s structured data format and are automatically validated via the IRP in real time.

Purpose and Legal Requirements

The main purpose of e-invoicing is to enhance transparency, reduce tax evasion, and simplify the GST return process by ensuring that every B2B invoice is verified at the time of generation.

The Central Board of Indirect Taxes and Customs (CBIC) has made e-invoicing mandatory for businesses based on their aggregate turnover:

• Phase 1 (October 2020): Businesses with turnover above ₹500 crore
  
  
• Phase 2 (January 2021): Businesses with turnover above ₹100 crore
  
  
• Phase 3 (April 2021): Businesses with turnover above ₹50 crore
  
  
• Phase 4 (April 2022): Businesses with turnover above ₹20 crore
  
  
• Phase 5 (October 2022): Businesses with turnover above ₹10 crore
  
  
• Phase 6 (August 2023): Businesses with turnover above ₹5 crore
  
  

As of the latest CBIC update, e-invoicing applies to all registered taxpayers whose aggregate turnover exceeds ₹5 crore in any financial year from 2017–18 onwards. However, certain entities such as banks, insurers, NBFCs, SEZ units, and government departments are exempted.

Businesses generating e-invoices must ensure that their accounting software supports the GSTN-specified JSON schema, integrates with the IRP, and generates valid IRNs for each eligible transaction.

Benefits of E-Invoicing

E-invoicing has transformed the compliance landscape in India. Below are some of its key benefits:

Faster Invoice Reconciliation

E-invoicing allows seamless synchronization of invoice data between suppliers, buyers, and the GST portal. Since all invoices are validated and registered by the IRP, it ensures that the invoice details automatically reflect in GSTR-1 returns and recipients’ GSTR-2A/2B. This reduces delays in reconciliation and minimizes disputes.

Reduced Manual Errors

Traditional invoicing often involves data entry errors or mismatched details between invoices and returns. With e-invoicing, data validation happens in real time at the source, preventing issues like duplicate entries, incorrect GSTINs, or mismatched totals.

Automatic Generation of E-Way Bills

The e-invoicing system is directly linked to the e-Way Bill portal. Once an invoice is validated, the transportation details can be auto-populated to generate an e-way bill instantly. This integration saves time and ensures consistency across all compliance documents.

Enhanced Compliance and Audit Trail

E-invoices are digitally signed and stored in a centralized repository. This not only ensures authenticity but also provides a transparent digital audit trail. Businesses can easily retrieve, verify, and present records during audits or compliance checks, improving overall governance.

What is E-Invoice in Tally Prime?

Overview of E-Invoicing Feature

Tally Prime, India’s leading accounting and business management software, has fully integrated e-invoicing capabilities to help users generate, validate, and manage GST-compliant invoices directly within the application. The feature simplifies the process of e-invoicing by automating IRN generation and QR code printing — all without leaving the Tally environment.

When a user creates an invoice in Tally Prime, the software automatically converts the data into the government-specified JSON format.

2. Direct Integration with Invoice Registration Portal (IRP)

Tally Prime’s direct integration with the NIC’s IRP ensures that the data flows seamlessly between your accounting system and the government portal. Users can send, cancel, or check the status of invoices directly within Tally without visiting the IRP website. This not only improves efficiency but also ensures real-time compliance.

3. Real-Time Validation of Invoice Data

Before sending any invoice data to the IRP, Tally Prime runs an internal validation check to ensure all mandatory fields — such as GSTIN, invoice type, HSN/SAC codes, and taxable value — are accurate. This proactive validation reduces the chances of rejection by the IRP and ensures data integrity across the system.

4. Built-in Error Detection and Correction

In case any discrepancy is detected, Tally Prime highlights the specific field or data point that caused the issue. Users can quickly correct the errors and re-upload the invoice without restarting the process. This built-in troubleshooting mechanism minimizes compliance delays and ensures smoother workflows.

5. Centralized E-Invoice and E-Way Bill Management

Tally Prime goes beyond e-invoicing — it offers a unified platform for both e-invoice and e-way bill generation. Businesses can manage invoices, track IRNs, generate e-way bills, and handle cancellations all from one dashboard. This reduces administrative workload and improves visibility across logistics and taxation operations.

6. Simplified Audit and Record Management

All e-invoices generated in Tally Prime are digitally authenticated and securely stored, ensuring easy retrieval during audits or compliance checks. Since every invoice contains a unique IRN and digital signature, it serves as valid proof of authenticity and reduces manual documentation efforts.

7. Enhanced Business Efficiency

By automating repetitive compliance tasks, Tally Prime frees up valuable time for finance teams to focus on strategic decision-making. The integration reduces the need for multiple software tools, streamlines workflows, and enhances coordination between sales, accounting, and compliance departments.

5. Print or Email Invoice:
   You can now print or email the government-validated invoice directly to the customer.
   
   

Understanding the E-Invoice JSON File

The e-invoice JSON file is a structured data format that captures all essential information about the transaction. Some of the key data fields include:

• Seller and Buyer GSTIN
  
  
• Invoice Number and Date
  
  
• Invoice Type (B2B, Export, etc.)
  
  
• Item Details (HSN, Quantity, Rate, Tax Amount)
  
  
• Total Taxable Value and GST Amount
  
  
• IRN (Invoice Reference Number)
  
  
• QR Code Data
  
  
• Acknowledgment Number and Date
  
  

Tally Prime securely stores this JSON file as part of your company data, allowing future retrieval for audits, reconciliations, or amendments. Users can also re-upload or cancel the invoice if necessary within the 24-hour IRP limit.

How to Check the Status of an E-Invoice in Tally

Once e-invoices are generated, tracking their status is crucial to ensure compliance and avoid mismatches during filing or audit. Tally Prime makes this process seamless by offering multiple ways to check and verify the e-invoice status.

View IRN and QR Status Within Invoice Entry Screen

Every invoice in Tally Prime displays its e-invoicing status directly within the voucher entry screen. After generating an e-invoice, users can:

1. Open the invoice from Gateway of Tally → Display More Reports → Account Books → Sales Register.
   
   
2. Select the relevant transaction and press Alt + I (More Details).
   
   
3. The screen displays:
   
   
   
   • IRN (Invoice Reference Number)
     
     
   • Acknowledgment Number and Date
     
     
   • QR Code details
     
     
   • Upload status (Success/Failed)
     
     

If the invoice is validated successfully by the Invoice Registration Portal (IRP), Tally will mark it as “IRN Generated.” Any invoice not uploaded or awaiting response will show “Pending.”

Check Invoice Upload and Validation Status from E-Invoice Report Menu

Tally Prime includes a dedicated E-Invoice Report feature that provides an overview of all invoices and their current statuses. To access:

• Navigate to Gateway of Tally → Display More Reports → Statutory Reports → GST → E-Invoice Reports.
  
  

Here, you can view invoices categorized as:

• Generated: Successfully validated and IRN generated.
  
  
• Pending: Awaiting upload to IRP.
  
  
• Cancelled: IRN cancelled within the allowed period.
  
  
• Failed: Rejected by IRP due to validation errors.
  
  

This dashboard offers a quick compliance snapshot and helps in tracking pending tasks efficiently.

Re-Upload Failed Invoices and Verify Updates from NIC Portal

Sometimes, invoices may fail to upload due to internet connectivity issues, invalid data, or IRP downtime. Tally Prime allows users to re-upload these invoices easily.

1. Go to E-Invoice Reports → Failed Invoices.
   
   
2. Select the invoice and choose Retry Upload (Alt + U).
   
   
3. Tally will resend the JSON to the IRP for validation.
   
   

To cross-verify, users can also visit the NIC e-Invoice portal (https://einvoice1.gst.gov.in) and check the IRN status using the Search → IRN option. The portal will display confirmation if the invoice is successfully registered.

How to Rectify Errors While Generating an E-Invoice

Even though Tally Prime automates validation, errors can still occur due to incorrect data entries or mismatched configurations. Understanding common errors and how to fix them helps ensure smooth e-invoicing operations.

Common Error Messages and Causes

Some frequent e-invoice errors and their possible causes include:

Error Message

Possible Cause

“Invalid HSN”

The HSN code entered doesn’t match GSTN’s prescribed format.

“Invalid GSTIN”

The buyer or seller GSTIN is incorrect, inactive, or mismatched with state code.

“IRP Authentication Failed”

Wrong or expired IRP credentials entered in Tally Prime.

“Duplicate Invoice Reference”

The same invoice number and date already exist on IRP.

“Invalid Document Type”

Invoice type (B2B, Export, SEZ) not correctly selected.

“Mandatory Field Missing”

Key fields like invoice number, place of supply, or HSN left blank.

“Invalid PIN Code”

Invalid or non-numeric postal code entered in party or company address.

Step-by-Step Error Resolution

Tally Prime allows users to correct and re-upload invoices without recreating them. Here’s how to resolve issues:

1. Identify the Error:
   From the E-Invoice Report, select the invoice showing “Failed” status and open the error log.
   
   
2. Edit the Invoice:
   Press Alt + E (Edit) and correct the mentioned details — such as GSTIN, HSN code, or tax rate.
   
   
3. Validate GST Details:
   Ensure the buyer and seller details match their official GST registration data.
   
   
4. Save and Re-upload:
   After correcting, press Alt + U (Upload to IRP). Tally resends the corrected JSON file for validation.
   
   
5. Confirm Success:
   Once validated, the IRN and QR code will automatically appear on the invoice, changing the status to “Generated.”
   
   

This process ensures you can quickly rectify issues without deleting or duplicating entries, maintaining a clean audit trail.

How to Cancel or Modify an E-Invoice (IRN)

Modifying an e-invoice is not permitted after an IRN is generated; instead, it must be cancelled and reissued if errors are found. The GST framework allows a defined time limit and procedure for cancellation.

When Can an E-Invoice Be Cancelled?

An e-invoice can be cancelled within 24 hours of IRN generation.
Once cancelled, the invoice number cannot be reused for new transactions — a new invoice must be generated with a different number.

E-invoices cannot be cancelled partially. If goods are returned or services are modified later, businesses must issue a credit note or debit note instead of cancelling the original invoice.

Steps to Cancel an E-Invoice in Tally

You can cancel an e-invoice directly from Tally Prime without visiting the IRP manually.

1. Go to Gateway of Tally → Display More Reports → E-Invoice Reports → Generated.
   
   
2. Select the invoice to be cancelled.
   
   
3. Press Alt + X (Cancel IRN).
   
   
4. Enter the Reason for Cancellation (e.g., data entry error, duplicate entry).
   
   
5. Confirm the action.
   
   
6. Tally sends the cancellation request to the IRP.
   
   

Once confirmed, the IRP will mark the invoice as “Cancelled”, and Tally will update the same in your records.

If you prefer manual cancellation, log in to the e-invoice portal, navigate to Search → Cancel IRN, and enter the IRN to cancel it.

E-Way Bill Cancellation Linked with E-Invoice

If an e-way bill was generated along with the e-invoice, cancelling the e-invoice in Tally automatically triggers a prompt to cancel the corresponding e-way bill as well.
Since both systems are linked, ensuring synchronized cancellation avoids compliance conflicts and duplicate transport documents.

How to Generate an E-Way Bill Along with an E-Invoice

Tally Prime simplifies logistics compliance by allowing users to generate e-way bills simultaneously with e-invoices — eliminating duplicate data entry and reducing manual errors.

Linking E-Way Bill Generation

When creating a sales invoice, you can enable automatic e-way bill generation:

1. Go to Gateway of Tally → F11 → Statutory Features.
   
   
2. Set ‘Enable E-Way Bill’ to Yes.
   
   
3. Enter details such as Mode of Transport, Vehicle Number, Distance (in km), and Transporter ID.
   
   

Once you generate the e-invoice:

• Tally automatically shares the relevant data (invoice value, HSN, quantity, distance) with the e-way bill system.
  
  
• Both the IRN and E-Way Bill Number (EWB No.) are generated and displayed on the screen.
  
  

This integration ensures that the transport document is created in real time without needing to log in to the e-way bill portal separately.

Validation and Printing

After successful generation:

• The invoice printout will display both the e-invoice QR code and the e-way bill number.
  
  
• Users can verify that the printed invoice matches the government-approved details.
  
  

In case an e-way bill is not required (e.g., invoice value under ₹50,000 or local delivery within the same premises), users can disable automatic generation for that specific transaction.

How to Print E-Invoices in Tally Prime

Printing e-invoices with complete government authentication details is essential for both compliance and transparency during transport or audits. Tally Prime provides simple options for printing e-invoices in standard or customized formats.

Enable “Print IRN & QR Code” in Invoice Print Settings

Before printing:

1. Go to Gateway of Tally → F12 → Printing → Sales Invoice.
   
   
2. Enable the option “Print e-Invoice Details (IRN and QR Code)”.
   
   
3. Save the configuration.
   
   

Once enabled, Tally automatically prints:

• The Invoice Reference Number (IRN)
  
  
• The Acknowledgment Number and Date
  
  
• The QR Code (for scanning and verification)
  
  

Print Using Standard or Customized Invoice Formats

Tally Prime supports:

• Standard Format: A ready-to-use layout with pre-defined placement for IRN, QR, and GST details.
  
  
• Customized Format: Businesses can modify their print templates using TDL or advanced configuration options to include company logos, disclaimers, or bilingual text while retaining compliance elements.
  
  

Ensure QR Code Readability for Verification

The QR code must be printed clearly enough to be scannable by GST officers or customers using mobile scanners. The code contains:

• Seller and Buyer GSTIN
  
  
• Invoice Number and Date
  
  
• IRN
  
  
• Invoice Value
  
  
• HSN Summary
  
  

Tally’s print engine automatically adjusts QR code size to ensure accuracy and readability across different paper formats (A4, A5, thermal).

How to View and Export E-Invoice Reports

Efficient reporting and export options make e-invoicing management more transparent and audit-ready. Tally Prime provides several in-built reports for viewing, analyzing, and exporting e-invoice data.

E-Invoice Reports in Tally Prime

Tally’s E-Invoice Report section provides real-time visibility into every invoice’s lifecycle.
Navigate to: Display More Reports → Statutory Reports → GST → E-Invoice Reports.

Here you can view:

• Generated Invoices: Successfully uploaded with IRN.
  
  
• Pending Invoices: Awaiting IRP submission.
  
  
• Cancelled Invoices: Invalidated within 24 hours.
  
  
• Failed Uploads: Rejected by IRP due to validation errors.
  
  

Each report lists the IRN, acknowledgment number, and upload date — providing a comprehensive compliance trail for auditors.

Exporting Data

Tally allows exporting e-invoice data in multiple formats for filing, review, or backup:

• JSON: For re-uploading or sharing with the IRP.
  
  
• Excel (XLSX): For management review or reconciliation.
  
  
• PDF: For archiving and audit presentation.
  
  

To export, open the E-Invoice Report → Select Range → Press Alt + E (Export) → Choose file format and destination folder.

E-Invoice Registers and Summaries

For deeper analysis, Tally generates registers and summaries that display e-invoicing data month-wise, party-wise, or voucher-type-wise.
These reports help:

• Identify missing IRNs.
  
  
• Track turnover linked with e-invoicing.
  
  
• Reconcile invoice data with GSTR-1 filings.
  
  

Exporting these summaries is highly useful during statutory audits or GST return verification, ensuring full visibility and control over compliance.

Troubleshooting Common Issues

Even with a powerful system like Tally Prime, users may occasionally encounter errors during e-invoice generation or upload. Understanding these issues and their causes can help you troubleshoot efficiently without halting operations.

E-Invoice Not Generating

One of the most frequent issues occurs when the e-invoice does not generate after attempting to upload it to the IRP (Invoice Registration Portal). The primary reasons for this may include:

• Missing or incorrect GST details for the supplier or recipient
  
  
• Invalid invoice format or missing mandatory fields (like HSN or SAC code)
  
  
• Internet connectivity issues interrupting the IRP communication
  
  

Solution:
Verify the mandatory fields in your invoice such as GSTIN, invoice number, and item HSN/SAC codes. Ensure your internet connection is stable and reattempt generating the IRN (Invoice Reference Number) from the E-Invoice Report menu in Tally Prime.

IRP Connection Timeout

If Tally Prime is unable to connect with the NIC IRP servers, it will display a “Connection Timeout” or “Unable to Reach IRP” error. This is usually caused by temporary network lags or IRP server downtime.

Solution:

• Check your system’s internet connection.
  
  
• Wait a few minutes and retry the upload.
  
  
• If the issue persists, confirm the IRP service status on the NIC portal (https://einvoice1.gst.gov.in/).
  
  

Tally Prime automatically stores pending invoices locally, so they can be re-uploaded once connectivity is restored.

Duplicate IRN Issues

Sometimes users unintentionally re-upload the same invoice, which triggers a “Duplicate IRN” error. This happens when the IRN for that invoice already exists in the IRP database.

Solution:
Use Tally Prime’s E-Invoice Report to check the IRN status. If an IRN has already been generated, you can retrieve it from the IRP using the “Get IRN Info” feature instead of generating a new one.

‍

Missing QR Code on Print

A missing QR code indicates that the invoice has not been successfully registered with the IRP or that the invoice print configuration is incomplete.

Solution:
Ensure that:

• The IRN and QR details are fetched from IRP.
  
  
• You’ve enabled the “Print IRN & QR Code” option in Tally’s print settings.
  If still missing, verify the QR print format using the F12 configuration menu in the print screen.
  
  

Invalid GSTIN or Mismatched HSN

Invalid GSTIN or mismatched HSN codes can block e-invoice generation entirely. This usually happens due to incorrect data entry or outdated master records.

Solution:
Cross-check GSTIN numbers from the official GST Portal and ensure your HSN/SAC codes comply with current GST notification structures. Tally Prime’s master validation feature can help detect such inconsistencies before uploading.

Best Practices for Smooth E-Invoicing in Tally

To ensure efficient and error-free e-invoicing, every organization should follow a consistent set of best practices. These habits not only streamline invoice generation but also safeguard compliance with GST laws.

1. Always Verify GST and HSN Data Before Invoicing

Incorrect master data is one of the most common causes of e-invoice rejection. Before generating an invoice:

• Validate the customer’s GSTIN on the GST portal.
  
  
• Ensure the correct HSN/SAC codes are assigned to all stock items.
  
  
• Confirm state codes and address details for both buyer and seller.
  
  

This proactive approach eliminates the need for later corrections and ensures the invoice is accepted by the IRP without errors.

2. Regularly Update Tally Prime to the Latest Release

Tally Solutions frequently releases updates that include e-invoice compliance improvements, bug fixes, and IRP integration enhancements.
Using an outdated version can lead to compatibility issues with the NIC portal.

To check for updates:

• Go to Help → About Tally Prime → Check for Updates.
  Always install the latest stable release to ensure smooth e-invoicing functionality.
  
  

3. Maintain Consistent Internet Connectivity

E-invoicing requires real-time data exchange with the NIC IRP portal. Any disconnection or lag can delay IRN generation or cause upload failures.
To avoid disruptions:

• Use a stable broadband or leased line connection.
  
  
• Ensure firewall settings don’t block Tally’s connection to IRP.
  
  
• Schedule bulk invoice uploads during off-peak hours if internet speed fluctuates.
  
  

4. Validate E-Invoices Before Dispatch

Before dispatching goods or sending the invoice to the customer, always verify that the e-invoice has:

• A valid IRN number generated by IRP
  
  
• A visible QR code on the printed invoice
  
  
• Accurate tax values matching your accounting entries
  
  

You can confirm this within Tally’s E-Invoice Report → View IRN Status, which shows whether an invoice is generated, pending, or cancelled.

5. Keep Backup of JSON Files for Future Audits

The IRP returns a digitally signed JSON file containing invoice data, IRN, and QR code information.
It’s essential to keep a backup of these files for:

• GST audits and compliance verification
  
  
• Internal accounting and reconciliation
  
  
• Proof of authenticity in case of disputes
  
  

Tally automatically stores JSON files locally, but maintaining an external backup—on a secure cloud or drive—is highly recommended.

6. Use Automation Features to Reduce Manual Work

Tally Prime offers automation for uploading, validating, and printing e-invoices. You can:

• Enable Auto Upload for IRN generation.
  
  
• Use Batch Upload for multiple invoices.
  
  
• Set default print preferences for QR and IRN display.
  
  

These automations save time and reduce dependency on manual input, leading to greater efficiency.

7. Periodically Review E-Invoice Reports

Regularly monitoring your e-invoice reports helps detect inconsistencies early.
Use Tally Prime’s E-Invoice Reports → Summary View to analyze:

• Generated vs Pending IRNs
  
  
• Cancelled or failed uploads
  
  
• Party-wise invoice statistics
  
  

This periodic review ensures you remain compliant and prevents missed uploads or reporting delays.

8. Integrate E-Way Bill with E-Invoicing

If your business involves frequent transportation of goods, linking e-way bill generation with e-invoice creation saves time and ensures accuracy.
Tally Prime’s integrated setup allows automatic e-way bill generation along with the e-invoice, reducing the need for dual data entry.
