Overview
What e-invoicing actually is
E-invoicing means reporting each B2B invoice to the Invoice Registration Portal (IRP) before issuing it — not emailing invoices.
The IRP validates the invoice, generates a unique Invoice Reference Number (IRN), and returns a digitally signed QR code.
Since 1 August 2023, it is mandatory for businesses with aggregate annual turnover above ₹5 crore.
Without a valid IRN, a B2B invoice has no legal standing under GST and the buyer's ITC can be denied.
Benefits
Why businesses set up e-invoicing through us
Open each benefit to see what it means for you.
Know if the mandate applies to you
AATO above ₹5 crore in any year since 2017-18 brings you under the mandate — permanently. We check your status before you spend on any integration.
IRN and QR on every invoice
The IRP returns a 64-character IRN and a signed QR code for each invoice. We set up the flow so every B2B invoice carries both, automatically.
GSTR-1 and e-way bill integration
E-invoices auto-populate GSTR-1 and Part A of e-way bills. Done right, e-invoicing reduces filing work instead of adding to it.
Invoices your buyers can claim ITC on
An invoice that needs an IRN but doesn't have one is invalid under GST — and your buyer's ITC gets denied. That is a customer-relationship problem, not just a tax one.

e-Invoicing Registration process — step by step

Step 1 of 5
1. Confirm you cross the ₹5 crore threshold
E-invoicing is mandatory for businesses with aggregate annual turnover above ₹5 crore, for B2B and export invoices. Each invoice must be reported to the Invoice Registration Portal (IRP) and carry an IRN and QR code.
2. Enable e-invoicing on the IRP — typically 1–2 working days
Register on the e-invoice portal (einvoice1.gst.gov.in) using the GSTIN with OTP verification — typically enabled within 1–2 working days.
3. Integrate your billing system via API or GSP
Generate API credentials for direct ERP integration, or connect through a GST Suvidha Provider (GSP) or accounting software. Map your invoice fields to the prescribed schema and test in the sandbox.
4. Generate IRN per invoice — cancel within 24 hours, never edit
From go-live, every B2B invoice is uploaded to the IRP for IRN generation before it is issued to the buyer. Invoices can be cancelled within 24 hours but not edited — a wrong invoice is cancelled and re-issued.
5. Mind the e-way bill handoff
E-invoice data auto-flows into the e-way bill system for Part A, but Part B (vehicle details) still has to be filled for movement of goods — train dispatch and logistics teams on the handoff.

Every GST-registered business with aggregate annual turnover above ₹5 crore in any financial year since 2017-18. Once you cross it, the obligation is permanent even if turnover falls later.
No. E-invoicing applies to B2B invoices, credit notes, debit notes, and exports. B2C invoices stay outside the IRP.
Not exactly — you keep billing as you do today. The invoice data goes to the Invoice Registration Portal, which validates it and returns the IRN and QR code. Think of it as authentication before the invoice reaches your buyer.
The invoice is not valid under GST without it, and your buyer's input tax credit on that invoice can be denied. You also face penalties for non-compliance.
Yes — banks, NBFCs, insurers, GTAs, passenger transport, and a few others are exempt even above the turnover threshold. We check your category first.
For larger turnovers there are reporting windows — invoices must be reported to the IRP within a set number of days of issue. Miss the window and the IRP rejects the invoice permanently.
