Frequently asked questions

How is e-way bill validity calculated?

Per Rule 138(10) of the CGST Rules: for normal cargo, validity is 1 day per 200 km (or part thereof) of distance. For Over-Dimensional Cargo (ODC), it is 1 day per 20 km. Each 'day' is exactly 24 hours measured from the time of generation. A 350 km journey of normal cargo gets 2 days; a 350 km ODC journey gets 18 days.

What happens if the e-way bill expires mid-transit?

Per section 129 of the CGST Act, transporting goods without a valid e-way bill is a violation - the goods and vehicle can be detained and penalty is up to 200% of the tax payable (or up to ₹25,000 even where no tax is payable). However, if expiry is due to genuine delay (vehicle breakdown, traffic, accident), the transporter can extend the validity within 8 hours of expiry under Rule 138(10) using the EWB-01 portal.

Who can extend an e-way bill before it expires?

Either the supplier (consignor) or the transporter who originally generated the EWB can extend it. The extension must be made within 8 hours before or after the original expiry time. The new validity is recalculated using the remaining distance. The reason for extension (e.g. 'natural calamity', 'transhipment', 'accident') must be selected from the dropdown on the portal.

What is the e-way bill threshold for Indian manufacturers?

An e-way bill is mandatory for movement of goods of consignment value exceeding ₹50,000 (some states have lower thresholds). For inter-state job work goods, EWB is mandatory regardless of value. For intra-state job work, threshold varies by state. The consignment value includes GST.

Can I generate e-way bills directly from my ERP?

Yes. ERPDrive integrates with the NIC e-way bill portal so you can generate, cancel, extend, and consolidate EWBs from the same screen where you raise the invoice. The system auto-calculates validity, auto-populates Part A from the invoice, lets you enter Part B vehicle details, and stores the EWB number against the invoice for traceability. Book a demo to see it.

What is the difference between Part A and Part B of EWB-01?

Part A contains the goods information: GSTIN of supplier and recipient, place of dispatch and delivery, invoice number, HSN, value, and reason for transport. Part A can be filed up to 15 days in advance and is locked once filed. Part B contains the transporter and vehicle details: transporter ID, vehicle number, mode of transport. Part B must be filled before movement starts. The EWB becomes valid only when both parts are complete.
