Overview

What Is GST E-Invoicing?

E-Invoicing (Electronic Invoicing) is a system where B2B invoices are electronically validated by the Invoice Registration Portal (IRP) before being shared with the GST portal. Every validated invoice gets a unique Invoice Reference Number (IRN) and a QR code.

The IRP checks your invoice data against GST master data, adds a digital signature, generates the IRN, and then automatically pushes the invoice details to both the GST portal (for GSTR-1) and the e-way bill system. No manual data entry needed anywhere.

E-invoicing is not about creating invoices — it's about validating and registering them with the government in real time. You still create invoices from your billing software, Tally, ERP, or our platform.

Get Started
What You Get After E-Invoicing

Every e-invoice returns with: IRN (64-character unique ID), Signed Invoice, QR Code (for B2C if applicable), and auto-population in your GSTR-1 draft. The e-way bill can also be generated simultaneously — Part A auto-filled.

IRN

Unique 64-char identity for every invoice

Digital Signature

Government-signed proof of authenticity

Applicability

Is E-Invoicing Mandatory for You?

E-invoicing is mandatory based on your aggregate turnover in any preceding financial year. Check the current thresholds below.

Turnover Thresholds (Current)
Aggregate turnover ≥ ₹5 Crore (FY 2023-24 onwards)
Mandatory
Aggregate turnover ≥ ₹10 Crore (FY 2022-23)
Mandatory
Aggregate turnover ≥ ₹20 Crore (FY 2021-22)
Mandatory
Aggregate turnover ≥ ₹50 Crore (FY 2020-21)
Mandatory
Aggregate turnover below ₹5 Crore
Not Required
B2B Supplies

All B2B tax invoices, credit notes, debit notes

SEZ Supplies

Supplies to SEZ units and SEZ developers

B2C Supplies

Not required for B2C invoices (except exports)

Exempt Supplies

Exempt goods/services, nil-rated invoices

Turnover includes all supplies: Aggregate turnover means total taxable + exempt + nil-rated + export turnover across all GSTINs under the same PAN. Even if your current year turnover is below threshold, if any preceding year crossed it — e-invoicing is mandatory.

You Create the Invoice

Create invoice as usual — in Tally, Busy, your ERP, or our platform. The format must be JSON as per government schema. Our software handles this automatically.

IRP Validates in Seconds

IRP checks: GSTIN active or not, supplier details match, tax calculations correct, duplicate IRN check. If anything fails — error returned with exact reason.

Everything Auto-Syncs

Validated invoice auto-pushed to GST portal (appears in GSTR-1), e-way bill Part A filled, buyer can see it in their GSTR-2B. Zero manual work.

Software Features

What Our E-Invoicing Software Does

Our platform handles the entire e-invoicing workflow — from invoice creation to IRN generation to GSTR-1 auto-population. No technical knowledge needed.

Instant IRN Generation

Push invoice to IRP and get IRN back in under 3 seconds. Bulk generation also supported — hundreds of invoices in one go.

Auto GSTR-1 Sync

E-invoices automatically appear in your GSTR-1 draft on the GST portal. No manual data entry, no mismatches, no errors.

Auto E-Way Bill Part A

E-way bill Part A is auto-populated from e-invoice data. Just add transport details and generate Part B — saves 70% time.

Error Detection

Before sending to IRP, our software pre-validates every field — wrong GSTIN, invalid HSN, tax mismatch — all caught before submission.

QR Code Generation

Every e-invoice gets a government-standard QR code embedded. Scannable by any QR reader — shows key invoice details instantly.

Complete History

Every IRN, every e-invoice, every error — stored and searchable. Download, print, or email any invoice from your dashboard anytime.

Credit / Debit Notes

Generate e-invoices for credit notes and debit notes too. Linked to original invoice IRN — fully compliant with government rules.

Seamless integration with Tally Prime, Busy, Zoho Books, and custom ERPs. Invoices flow directly — no double entry.

Real-Time Alerts

Get notified on successful IRN generation, errors, failures, and IRN cancellations. Instant email + dashboard alerts for every event.

Exemptions

Invoices Exempt from E-Invoicing

Not every invoice needs e-invoicing, even if you're above the threshold. Here's what's excluded — these can be issued as regular invoices.

B2C Invoices

Invoices for supplies to unregistered persons (B2C) — no e-invoice needed.

Exempt / Nil-Rated Supplies

Invoices for goods/services that are exempt from GST or have 0% tax rate.

Invoices ≤ ₹2,500

Invoices where total value doesn't exceed ₹2,500 — except in case of reverse charge.

IGST on Import

Invoices for import of goods where IGST is paid at customs — covered by bill of entry.

Special Categories

Insurance companies, banking companies, financial institutions, NBFCs, goods transport agencies, passenger transport, and cinema halls.

What About E-Way Bill Exemption?

Even if an invoice is exempt from e-invoicing, it may still need an e-way bill if goods are being transported. E-invoicing exemption does NOT automatically mean e-way bill exemption. They are separate compliance requirements.

Common mistake: Many businesses think that since B2C is exempt from e-invoicing, they can split B2B invoices into multiple B2C invoices below ₹2,500 to avoid e-invoicing. This is treated as tax evasion and can attract penalty under Section 122 of CGST Act.
Our software auto-detects: It automatically checks whether an invoice needs e-invoicing or not based on supply type, value, and category. You never have to remember the rules — the software handles it.

Penalties

What If You Don't Comply?

Non-compliance with e-invoicing attracts serious penalties. The government tracks mismatches between your GSTR-1 and e-invoice data automatically.

₹25,000 Fine

Penalty under Section 122 for not generating e-invoice for eligible supplies.

GSTR-1 Mismatch

Manual invoices in GSTR-1 that don't match e-invoice data trigger auto-generated notices.

ITC Blockage

Buyer's ITC gets blocked if your invoice doesn't have valid IRN. This affects your business relationships.

Scrutiny Risk

Repeated non-compliance flags your GSTIN for scrutiny, potential assessment, and GSTIN suspension.

The government tracks everything automatically. The GST portal cross-matches e-invoice data with GSTR-1 filings in real time. Every mismatch is flagged, every missing IRN is noted. Manual invoicing for B2B is no longer an option for businesses above threshold.
IRN Cancellation

Can IRN Be Cancelled?

Yes — but only within 24 hours of IRN generation. After 24 hours, the IRN cannot be cancelled. In that case, you'll need to issue a credit note (which itself needs e-invoicing).

Within 24 Hours

IRN can be cancelled on the IRP portal. Cancelled IRN is marked as invalid. The invoice data is removed from GST portal and e-way bill system.

After 24 Hours

IRN cannot be cancelled. You must issue a credit note with a new e-invoice (new IRN). The original IRN stays in records as a valid invoice.

Our Software Handles This

One-click IRN cancellation from dashboard. Timer shows remaining cancellation window. If 24 hours have passed, it auto-prompts you to create a credit note instead.

When to Cancel an IRN?
  • Wrong GSTIN entered — Buyer's GSTIN was typed incorrectly in the invoice
  • Duplicate invoice — Same invoice was pushed to IRP twice (second one should be cancelled)
  • Wrong HSN / Tax rate — Significant error in HSN code or tax rate that changes tax liability
  • Invoice not needed — Order cancelled before supply, invoice created by mistake
  • Test invoice — Testing e-invoicing and want to remove test data
Important: Cancelling an IRN does NOT cancel the e-way bill if it was already generated. You need to cancel the e-way bill separately from the e-way bill portal.
FAQ

E-Invoicing Questions

Is e-invoicing the same as digital invoicing?

No. Digital invoicing means creating an invoice on a computer (PDF, Excel, etc.). E-invoicing means that invoice is electronically validated by the government's IRP and gets a unique IRN. Every e-invoice is digital, but not every digital invoice is an e-invoice.

Can I generate e-invoice manually on IRP portal?

Technically yes — the IRP portal has a manual entry option. But it's extremely tedious and not practical for businesses with more than 5-10 invoices per day. Our software automates this completely — you don't need to visit the IRP portal at all.

What happens if IRP server is down?

You cannot generate IRN during downtime. The government has provided a grace period in some cases — but generally, you must wait for IRP to come back online. Our software auto-retries and queues your invoices. You get notified the moment IRP is back and your IRNs are generated automatically.

Do I still need to file GSTR-1 after e-invoicing?

Yes. E-invoicing auto-populates your GSTR-1 draft, but you still need to review and file GSTR-1 before the due date. E-invoicing reduces your work by 90% — but filing is still your responsibility.

Can I use my existing billing software?

Yes. Our software integrates with Tally Prime, Busy, Zoho Books, ERPNext, and most popular billing/ERP systems. Your invoices flow directly from your software to IRP — no change in your existing workflow. We also offer a standalone invoice creator if you don't use any software.

Is e-invoice required for export invoices?

Yes. Export invoices (whether to SEZ or outside India) are treated as B2B supplies and require e-invoicing if you're above the threshold. The only exception is B2C exports below ₹2,500.

What data is mandatory in an e-invoice?

Key mandatory fields: Supplier GSTIN, buyer GSTIN, invoice number, invoice date, item details (HSN/SAC code, quantity, unit, tax rate, tax amount), total value, place of supply, and tax breakdown (CGST, SGST, IGST). Our software ensures all fields are filled before submission.

Can the buyer reject an e-invoice?

No. Once IRN is generated, the e-invoice is considered valid and registered with the government. The buyer cannot reject it from the GST portal. Any dispute is a commercial matter between buyer and seller — not a GST portal function.

What if I issue an invoice without e-invoicing by mistake?

You should immediately e-invoice it. Generate the e-invoice with the same invoice number and date. If IRP rejects it (duplicate number scenario), you may need to cancel the original and re-issue. The sooner you act, the better — delay increases penalty risk.

Is there a limit on how many e-invoices I can generate?

No limit. You can generate unlimited e-invoices through our software. Whether it's 10 invoices a month or 10,000 — our API handles it. Bulk upload via Excel/CSV is available for high-volume users.
