E-invoice and e-way bill: the 2026 rules for GST businesses
Who has to e-invoice, how fast invoices must reach the IRP, and how an e-way bill differs from an e-invoice — plus how Finvosmart keeps every invoice ready for both. Direct IRN and e-way bill generation from Finvosmart is coming soon; until then you generate them on the government portals.

E-Invoice & E-Way Bill at a glance
Every field the IRP needs
GSTINs, place of supply, HSN/SAC codes, taxable value and tax on every line, and invoice numbers of up to 16 characters — the e-invoice schema's own limit.
Numbers kept with the invoice
Record the e-way bill number, LR number and purchase order reference on the invoice; they print on it and stay with it.
GSTR-1 from your books
Finvosmart builds GSTR-1 from the invoices you raised, so you can check what the IRP passed on to your return against your own records.
Coming soon: IRN from Finvosmart
Generating the IRN and e-way bill straight from the invoice, through a GST Suvidha Provider, is being built.
Who needs to generate e-invoices in 2026
E-invoicing is mandatory for every GST-registered business whose aggregate annual turnover (AATO) has crossed ₹5 crore in any financial year since 2017-18. This limit has applied since 1 August 2023 and is unchanged in 2026. Turnover is counted across all GSTINs under the same PAN, not per registration.
Larger businesses have a deadline too. Since 1 April 2025, if your AATO is ₹10 crore or more, you must report each invoice, credit note and debit note to the IRP within 30 days of its date — the portal rejects anything older. Some sectors, such as banks, insurers and SEZ units, are exempt from e-invoicing.
E-invoice and e-way bill are not the same thing
An e-invoice validates the invoice itself. An e-way bill authorises the movement of goods. They often go together, but not always:
- An e-way bill is generally needed when you move goods worth more than ₹50,000 — whatever your turnover.
- A services business above ₹5 crore needs e-invoices but may never need an e-way bill.
- A small trader below ₹5 crore may need e-way bills but not e-invoices.
- E-invoice data fills Part A of the e-way bill; you add the vehicle or transporter details (Part B) to complete it.
- An e-way bill can only be generated within 180 days of the invoice date.
Generating them today, with Finvosmart invoices
Until direct generation is ready, the work splits cleanly. You raise the GST invoice in Finvosmart, where tax, place of supply and HSN codes are already worked out. You report it on an Invoice Registration Portal to get the IRN and signed QR code, and raise the e-way bill on the e-way bill portal when goods move. Then you note the e-way bill number on the invoice in Finvosmart, so it prints on the copy that travels with the goods.
Because the figures come from one invoice, the amounts you key into the portals match your books — and at month end your GSTR-1 from Finvosmart lets you check that every e-invoice reached your return.

Frequently asked questions
What is the e-invoice turnover limit in 2026?
E-invoicing is mandatory if your aggregate annual turnover crossed ₹5 crore in any financial year from 2017-18 onwards. The limit has applied since 1 August 2023 and is unchanged in 2026. Turnover is counted across all GSTINs under the same PAN.
What is the 30-day e-invoice reporting rule?
Since 1 April 2025, businesses with an aggregate annual turnover of ₹10 crore or more must report each invoice, credit note and debit note to the IRP within 30 days of its date. The portal rejects documents older than that, so report promptly.
What is an IRN?
The Invoice Reference Number is a unique number the government's Invoice Registration Portal issues for each e-invoice it accepts. An invoice that needs e-invoicing is not valid without one.
Do I need an e-way bill if I already generate e-invoices?
Often, yes — they serve different purposes. An e-way bill covers the movement of goods, generally above ₹50,000 in value. E-invoice data fills Part A of the e-way bill, and you add the vehicle details in Part B.
Can Finvosmart generate the IRN for me?
Not yet. Direct IRN and e-way bill generation is being built. Today, Finvosmart prepares GST invoices with every detail the IRP needs, and you generate the IRN and e-way bill on the government portals and note the numbers on the invoice.
Does e-invoicing replace GSTR-1?
No. Invoices reported on the IRP flow into GSTR-1 automatically, but you still review and file the return. Finvosmart's GSTR-1 export helps you check it against your books.
