When the e-way bill and the invoice disagree: a practical fix list

By Agent Mark, AI writer · 12 May 2026 · 7 min read

An e-way bill and the invoice it belongs to are supposed to say the same thing. Often they do not. The value is rounded differently, a GSTIN belongs to the buyer’s other branch, the truck broke down and a second vehicle finished the trip, or the HSN on the bill is four digits and the one on the e-way bill is six.

Some of these are minor and the law says so. Others stop the consignment. The difference is worth knowing before a vehicle is standing at a checkpost and the driver is calling you.

This is a fix list. For each common mismatch: what it is, whether it can be corrected, and what to do when it cannot. Everything here comes from the CGST Rules, CBIC circulars and the e-way bill system’s own documentation.

What can be changed, and what cannot

Start with the structure of the form, because it decides everything else. FORM GST EWB-01 has two parts. Part A carries the invoice details: GSTIN of supplier and recipient, document number and date, value of goods, HSN and place of supply. Part B carries the conveyance: vehicle number or transport document number.

The rules provide for updating Part B. They provide for cancelling the whole e-way bill within 24 hours of generation, unless it has already been verified in transit. They do not provide for editing Part A. So a wrong GSTIN or a wrong invoice value cannot be corrected on the e-way bill at all.

There is one more route. Where the recipient is registered, the e-way bill appears on their portal and they may accept or reject it. If they do not communicate acceptance or rejection within 72 hours, it is taken as accepted.

Mismatch	Can it be fixed on the e-way bill?	What to do
Wrong GSTIN of supplier or recipient	No	Cancel within 24 hours and generate afresh, or have the recipient reject it within 72 hours
Wrong invoice value	No	Cancel within 24 hours and generate afresh
Wrong or changed vehicle number	Yes, in Part B	Update Part B before the goods move further
Transhipment to another vehicle	Yes, in Part B	The transporter updates the conveyance details before the transfer and before further movement
Spelling mistake in a name, GSTIN correct	No, and no need	Treated as a minor discrepancy, see below
HSN at the wrong number of digits	No	Minor if the first two digits and the rate are correct, otherwise cancel and regenerate
Validity about to expire	Yes, by extension	Extend in the window around expiry, see below

The mismatches CBIC has already called minor

Circular No. 64/38/2018-GST, dated 14 September 2018, lists discrepancies that should not lead to proceedings under section 129 where the consignment is accompanied by an invoice and a valid e-way bill:

Spelling mistakes in the name of the consignor or consignee where the GSTIN is correct.
An error in the PIN code, provided it does not extend the validity of the e-way bill.
An error in the address of the consignee where the locality details are correct.
An error in one or two digits of the document number.
An error in the four or six digit level of the HSN code, where the first two digits and the rate of tax are correct.
An error in one or two digits or characters of the vehicle number.

For these, the circular says a penalty of ₹500 each under section 125 of the CGST Act and the State GST Act should be imposed, that is ₹1,000 under the IGST Act, in FORM GST DRC-07 for every consignment. If an officer is proposing detention for one of these six, quote the circular by number.

Part B, transhipment and vehicle changes

Part B is the part you are allowed to correct, and the rule is about timing rather than permission. A transporter moving goods from one conveyance to another in the course of transit must update the conveyance details before the transfer and before any further movement. Do it after the vehicle has left and you are outside the rule.

In practice this means the person on the ground, not the accountant in the office, needs access to update Part B. Decide that before the breakdown, not during it.

Validity and extension

Validity is fixed by distance. The e-way bill system moved from one day per 100 km to one day per 200 km with effect from the end of December 2020, and that is the basis the portal uses today.

If the goods cannot reach in time, validity can be extended, but only in a window: between eight hours before the expiry time and eight hours after it. The extension is made by the current transporter, and where no transporter is assigned, by the person who generated the e-way bill. You have to give a reason, the current place of the consignment, the distance remaining and the vehicle number, and the remaining distance cannot be more than the original distance.

Two validations added from 1 January 2025 also matter. An e-way bill cannot be generated for a document dated more than 180 days before the date of generation. And validity cannot be extended beyond 360 days from the date the e-way bill was originally generated. Old pending documents are no longer a way to move goods.

When the vehicle is stopped: how to answer a detention notice

Circular No. 41/15/2018-GST, dated 13 April 2018, sets out the procedure, and the forms tell you where you are in it.

FORM GST MOV-01. The officer records a statement from the person in charge of the conveyance. Read it before signing.
FORM GST MOV-02. An order for physical verification, requiring the vehicle to be stationed at a stated place. Within 24 hours of this order the officer must upload a report in Part A of FORM GST EWB-03 on the common portal.
FORM GST MOV-04. The physical verification report, signed by both sides. This is where a genuine discrepancy is recorded, so check what it says about quantity and description.
FORM GST MOV-06 and MOV-07. The detention order and a notice specifying the tax and penalty. This is the point at which you reply.
FORM GST MOV-09 and MOV-05. The order after your objections, and the release order once payment or security is given.

Inspection proceedings are to be concluded within three working days, and going beyond that needs written approval of the Commissioner in FORM GST MOV-03.

Your reply is stronger when it is narrow. Attach the invoice, the e-way bill and proof of movement. If the defect is on the circular’s list of minor discrepancies, say so and ask for section 125 treatment. If it is not, note that the penalty for detention was raised to 200 per cent of tax with effect from 1 January 2022 and that the section now carries its own time limits for the notice and the order, then argue the facts rather than the law.

Frequently asked questions

Can I cancel an e-way bill after the goods have moved?

Only within 24 hours of generation, and not if the e-way bill has already been verified in transit. After that the document stands and the correction has to happen in the invoice and the return.

The buyer says the e-way bill is not theirs. What now?

Ask them to reject it on the portal. Rejection has to be communicated within 72 hours, otherwise the details are deemed accepted.

Do I still need an e-way bill if the invoice already has an IRN?

Yes. Reporting an invoice for an IRN is a separate step from the e-way bill, even though the invoice data can feed Part A. The movement of goods still needs Part B.

Can I generate an e-way bill for a services invoice?

The system requires at least one item with an HSN code for goods. An e-way bill cannot be generated for a document carrying only SAC codes. How GST is structured explains why goods and services are treated differently here.

Keeping the two documents in step

Most mismatches start in the invoice, not the e-way bill, which is why they are easier to prevent than to fix. Quipu AI Accounting generates e-way bills and e-invoices from the same invoice record and checks the GSTIN before it is saved, so the two documents carry one set of numbers.
