E-Invoice vs E-Way Bill: What Each One Is, When It Is Required, and How They Connect
An e-invoice authenticates the invoice itself; an e-way bill authorises the movement of goods. They have different thresholds, different triggers, and different consequences for getting them wrong — and in many dispatches you need both.
E-invoicing and the e-way bill are often spoken about together and frequently confused, because a single dispatch of goods can require both and the portal links them. But they answer different questions. The e-invoice asks: is this invoice genuine and reported to the government? The e-way bill asks: is this movement of goods authorised? A business can be fully compliant on one and in breach on the other.
What each document is
An e-invoice is not a special invoice format. It is an ordinary tax invoice whose details have been uploaded to the Invoice Registration Portal (IRP), which validates them and returns an Invoice Reference Number (IRN) and a signed QR code. Without a valid IRN, the invoice is not treated as a valid tax invoice under GST at all — which puts the recipient's ITC at risk and breaks GSTR-1 auto-population for the supplier.
An e-way bill is a movement permit. It is generated on the e-way bill portal for the transport of goods above a threshold value, carries a unique EBN (e-way bill number), and must accompany the consignment — physically or digitally — for the whole journey. It has a validity period tied to the distance to be covered.
When each one is required
| Attribute | E-invoice | E-way bill |
|---|---|---|
| Purpose | Authenticates and reports the invoice | Authorises the movement of goods |
| Portal | Invoice Registration Portal (IRP) | E-way bill portal (EWB) |
| Identifier issued | IRN + signed QR code | EBN (e-way bill number) |
| Threshold | Aggregate annual turnover above ₹5 crore in any year from 2017-18 onward | Consignment value above ₹50,000 (inter-state); intra-state limits vary by state, some ₹1,00,000 |
| Applies to | B2B, exports, and B2G supplies; not B2C | Movement of goods by any mode; not applicable to most services |
| Timing | At or before issuing the invoice; reporting within 30 days for turnover ₹10 crore and above | Before the movement of goods begins |
| Consequence of default | Invoice invalid; ITC and GSTR-1 impact; penalty | Goods and vehicle liable to detention and penalty under Section 129 |
The turnover test for e-invoicing is based on aggregate turnover in any financial year from 2017-18 onwards — once a business crosses the limit in any of those years, e-invoicing applies going forward even if turnover later falls. It is entity-wide across all GSTINs on the same PAN, not per registration.
How the two connect
Where a supply requires an e-invoice, the e-way bill can be generated directly from the IRP using the IRN, with Part A of the e-way bill pre-filled from the reported invoice data. The transporter then adds Part B (vehicle number) before movement. This link is also why an incorrect e-invoice propagates: if the IRN carries a wrong value or GSTIN, the e-way bill built on it inherits the error, and so does the recipient's GSTR-2B.
The 30-day reporting window
For businesses with aggregate turnover of ₹10 crore and above, an e-invoice must be reported to the IRP within 30 days of the invoice date; after that the IRP rejects it and the invoice cannot be regularised. This is separate from the turnover threshold for e-invoicing itself — a business between ₹5 crore and ₹10 crore must e-invoice but is not yet inside the 30-day hard limit. Confirm the current threshold against the latest advisory before relying on it, as this limit has been progressively lowered.
Practical points that get missed
- E-invoicing does not apply to B2C supplies, but dynamic QR code requirements may apply separately for large B2C invoices.
- An e-way bill can be required even with no e-invoice — for example, moving goods on a delivery challan for job work, or a B2C sale above the threshold.
- Credit and debit notes for B2B supplies also need an IRN where e-invoicing applies, not just the original invoice.
- E-way bill validity is distance-based and expires; a consignment held up in transit past validity needs the bill extended before movement resumes.
- Both systems require two-factor authentication for login, so shared credentials for a billing team no longer work.
Whichever documents a dispatch needs, the compliance still ends in a reconciliation — matching what was invoiced and reported against GSTR-1 and GSTR-3B. GST Reco Pro converts those returns from PDF into structured Excel in the browser, with no upload, so the monthly check is quick.

What is the difference between an e-invoice and an e-way bill?
An e-invoice authenticates the tax invoice by reporting it to the Invoice Registration Portal, which returns an IRN and QR code. An e-way bill authorises the physical movement of goods above a value threshold and must travel with the consignment. One is about the document, the other about the transport.
What is the turnover limit for e-invoicing?
E-invoicing applies to businesses whose aggregate turnover exceeded ₹5 crore in any financial year from 2017-18 onwards. It is measured entity-wide across all GSTINs on the same PAN, and once crossed it continues to apply even if turnover later falls.
What is the e-way bill threshold?
An e-way bill is required for the movement of goods where the consignment value exceeds ₹50,000 for inter-state movement. Intra-state thresholds are set by each state and some use a higher ₹1,00,000 limit, so check the rule for the state of movement.
Do I need both an e-invoice and an e-way bill for the same supply?
Often yes. A B2B dispatch of goods above ₹50,000 by a business over the e-invoicing turnover limit needs an IRN for the invoice and an e-way bill for the movement. The e-way bill can be generated from the IRP using the IRN, which pre-fills Part A.
What is the 30-day rule for e-invoices?
Businesses with aggregate turnover of ₹10 crore and above must report each e-invoice to the IRP within 30 days of the invoice date. After 30 days the portal rejects it and the invoice cannot be validated, which affects both the supplier's GSTR-1 and the recipient's ITC.
