GST E-Invoicing and E-Way Bill: Rules, Applicability, and Implementation Guide

E-invoicing and e-way bill are two critical compliance requirements under GST that affect how businesses generate invoices and transport goods. Understanding when they apply and how to implement them correctly prevents penalties and operational disruptions.

E-Invoicing Under GST

E-invoicing does not mean generating invoices on a government portal. It means getting your regular invoices validated and registered on the Invoice Registration Portal (IRP) and obtaining a unique Invoice Reference Number (IRN).

Current applicability threshold (as of April 2025):

• Mandatory for businesses with aggregate turnover exceeding Rs 5 crores in any previous financial year from 2017-18 onwards
• The threshold has been progressively reduced from Rs 500 crores (2020) to Rs 5 crores (2023)
• Further reduction to Rs 1 crore or lower may be notified

Who Must Generate E-Invoices?

E-invoicing is mandatory for:

• B2B supplies (business to business)
• B2B exports
• Supplies to SEZ (with or without payment)

E-invoicing is NOT required for:

• B2C supplies (business to consumer)
• Imports
• Nil-rated and exempt supplies
• Specific categories: Insurance, banking, financial institutions, NBFCs, GTA, passenger transport, cinema tickets (with specific notifications)

How E-Invoicing Works

1. Generate invoice in your billing software (Tally, SAP, custom software)
2. Push the invoice data in JSON format to the IRP
3. IRP validates the data, generates IRN and QR code
4. IRN and signed QR code are returned to your system
5. Include IRN and QR code on the printed invoice
6. IRP automatically populates your GSTR-1 with the invoice details

Benefits of e-invoicing:

• Auto-population of GSTR-1 (reduces manual filing effort)
• Reduced errors and mismatches
• Faster ITC availability for buyers
• Standardized invoice format across the supply chain
• Reduced tax evasion through real-time reporting

E-Way Bill Rules

An e-way bill is required for movement of goods when the consignment value exceeds Rs 50,000. It is generated on the e-way bill portal (ewaybillgst.gov.in).

When e-way bill is required:

• Movement of goods with value exceeding Rs 50,000
• Interstate movement (even below Rs 50,000 in some cases for specified goods)
• Movement by registered person or transporter

When e-way bill is NOT required:

• Goods transported by non-motorized conveyance
• Goods transported from port/airport to customs station or ICD
• Movement within the same state by the same person (in some states, threshold varies)
• Goods specified in Annexure to Rule 138(14)—includes LPG, kerosene, postal baggage, used personal effects, etc.
• Movement of goods less than 50 km within the state

E-Way Bill Generation Process

1. Login to ewaybillgst.gov.in
2. Select "Generate New" under E-Way Bill
3. Choose transaction type: Outward (if you are the supplier) or Inward (if you are the recipient)
4. Enter invoice details, item descriptions, HSN codes, and values
5. Enter transportation details: Vehicle number, transporter ID, or transport document number
6. System generates e-way bill with a unique 12-digit EBN (E-Way Bill Number)

Validity of e-way bill:

• Less than 200 km: 1 day
• Every additional 200 km: 1 additional day
• Over-dimensional cargo: 1 day per 20 km

Tally Integration for E-Invoicing and E-Way Bill

For businesses using Tally Prime, both e-invoicing and e-way bill can be managed:

E-Invoicing in Tally:

• Enable GST e-invoicing in Tally Gateway > F11 Features
• Enter IRP credentials (NIC portal login)
• Generate e-invoice directly from voucher
• IRN and QR code are automatically added to the invoice print format

E-Way Bill in Tally:

• Enable e-way bill in Tally configurations
• Enter transporter details in the voucher
• Generate e-way bill from the sales voucher
• Track validity and update vehicle numbers

Common Penalties and Issues

E-invoicing violations:

• Invoice without IRN is not a valid invoice under GST
• Buyer cannot claim ITC on invoices without valid IRN
• Penalty under Section 122: Up to Rs 25,000 or 100% of tax, whichever is higher
• IRN must be generated within 30 days of invoice date (for turnover above Rs 100 crores: within 7 days)

E-way bill violations:

• Movement without valid e-way bill: Goods and vehicle can be detained
• Penalty: Tax amount or Rs 10,000, whichever is higher
• Release of goods: On payment of applicable tax and penalty, or furnishing security

Implementation Checklist

For businesses newly coming under e-invoicing:

1. Register on the IRP portal (einvoice1.gst.gov.in)
2. Update your billing software (Tally, SAP, etc.) to support e-invoicing
3. Test with sandbox environment before going live
4. Train staff on the new workflow
5. Set up error handling for API failures
6. Maintain a backup process for portal downtime

Both e-invoicing and e-way bill compliance are increasingly automated. Businesses that integrate these with their accounting software (especially Tally Prime) see significantly fewer errors and penalties compared to manual portal-based generation.
