Is E-Invoicing About to Apply to You? How to Tell Before a Buyer Tells You

The thing to understand about e-invoicing is that it is not a new invoice format. It is a step that happens before your invoice is a valid document: you report it to an Invoice Registration Portal, the portal returns an Invoice Reference Number and a signed QR code, and only then is the invoice complete. An invoice that should have an IRN and does not is treated as invalid, which means your buyer cannot claim credit on it. That is why this usually reaches people through an annoyed customer rather than through a notice.

The threshold, and the part that catches people

The mandate currently applies to businesses whose aggregate annual turnover has exceeded ₹5 crore, under Notification 10/2023-Central Tax, in force from 1 August 2023. Lowering it further has been discussed publicly more than once without a notification following, so treat the figure as correct-as-written and confirm it on the GST portal before you plan around it.

The clause that catches people is not the number — it is the lookback. The test is whether your turnover crossed the threshold in any financial year since 2017-18, not whether it is above it today. A business that had one unusually large year and has since settled lower is still covered. Falling back under the line does not switch the obligation off.

The ₹10 crore rule is a different rule

This is the commonest confusion in the topic, so it is worth separating clearly. There is a second, narrower rule about how quickly you must report: taxpayers at or above ₹10 crore aggregate annual turnover cannot report an invoice to the portal more than thirty days after its date, and the portal rejects late attempts. That is a reporting window, not an applicability threshold.

So a business between ₹5 crore and ₹10 crore needs IRNs but is not subject to the thirty-day block. If you have read that e-invoicing starts at ₹10 crore, you have almost certainly read a description of this rule, or an article that has not been updated since an earlier threshold.

Who is exempt even above the threshold

Some categories are excluded regardless of turnover. Banking companies and financial institutions including NBFCs, insurers, goods transport agencies, passenger transport services, multiplex cinema operators, and SEZ units — units, not developers. If you are in one of those, the question stops here.

It is also worth being clear about what the mandate covers: B2B supplies, exports, SEZ supplies and deemed exports. Pure B2C invoicing is not in scope in the same way, which is why a retailer and a service company of identical size can have entirely different obligations.

What actually changes in your week

Less than people fear, and in a different place than they expect. The invoice content barely changes. What changes is that there is now a step between "raise the invoice" and "send the invoice", and that step can fail — a wrong GSTIN, a missing mandatory field, a duplicate number will all be rejected by the portal rather than quietly accepted by your customer. Most of the pain that businesses report in their first month is not the IRN itself; it is discovering how much of their master data was wrong.

Which is the honest reason to get your invoice hygiene right before the threshold reaches you, not after.

Where Grovia sits on this, plainly

Grovia prepares the e-invoice payload for an invoice and gives it to you to upload on the portal, and lets you record the IRN against the invoice once you have it. It is not connected to a GSP, and it does not transmit anything to a government system on your behalf. That is a deliberate position rather than a gap: connecting to the IRP is something we will do once it can be done properly, with the right account and the right audit trail behind it, and we would rather say so than imply an automation that does not exist.

If you are above the threshold and raising a high volume of invoices, you want a provider with a live IRP integration, and you should choose one on that basis. If you are below it, or just over and raising a manageable number, the manual path is genuinely workable and is what most businesses in that band actually do.

A test you can run today

Pull your aggregate turnover for every financial year since 2017-18 — not just last year. If any one of them crossed the threshold, you are in scope now, and the question is not whether but how. If none did, check how far the most recent year got: the gap between your current turnover and the threshold, divided by your growth rate, is roughly how long you have to get your GSTIN data clean.

Frequently Asked Questions

What is the current e-invoicing turnover threshold in India?

₹5 crore aggregate annual turnover, under Notification 10/2023-Central Tax effective 1 August 2023. Because proposals to lower it surface periodically, confirm the current position on the GST portal before making a decision on it.

My turnover has fallen below the threshold. Am I still covered?

Yes. The test looks at whether turnover exceeded the threshold in any financial year since 2017-18. A later fall does not remove the obligation.

Is the e-invoice threshold ₹5 crore or ₹10 crore?

₹5 crore for applicability. The ₹10 crore figure belongs to a separate rule that bars reporting an invoice more than thirty days after its date. The two are often mixed up.

Does e-invoicing apply to B2C sales?

The mandate covers B2B, export, SEZ and deemed-export supplies. B2C invoicing is not in scope in the same way, though QR code requirements may apply separately depending on your circumstances.

What happens if I raise an invoice without an IRN when one was required?

It is treated as an invalid document, so the buyer cannot claim input tax credit against it. In practice you will usually hear about it from the buyer before anyone else.

Can I generate e-invoices without a paid integration?

Yes. The portal accepts manual upload, and for modest volumes that is a reasonable way to work. Integrations earn their keep at volume, where uploading by hand stops being realistic.
