E-Way Bill Calculator

Either the consignor, the consignee or the transporter, in that order of responsibility. If the supplier is unregistered and the recipient is registered, the recipient is treated as the consignor. Once any party generates the EWB and shares the EBN, the others may rely on it.

Validity scales: 1 day per 200 km. For 600 km, validity is 3 days. The day count begins from the first movement entry (Part B updated). The driver should reach the destination before validity expires; otherwise the EWB must be extended.

Cancellation is allowed within 24 hours of generation if goods have not moved or details are wrong. Extension is allowed up to 8 hours before or after expiry under specific circumstances (vehicle breakdown, transhipment delay, accidents) with reason logged.

Section 122 of the CGST Act: a penalty of ₹10,000 or the amount of tax sought to be evaded, whichever is higher. Goods and vehicles can be detained. Detention release usually requires payment of applicable tax and penalty.

Yes. One e-way bill is generated by the principal supplier (Bill From → Bill To). The intermediate party may generate a second EWB or use Part B updates if vehicle changes hands. Most ERP systems generate the EWB at invoice level automatically.

Part A is the consignment details (invoice info, value, HSN). Part B is the transport details (vehicle number, transporter ID). Part A is filed by the supplier; Part B is filed by the transporter when the vehicle is finalised. Both must be filled before movement.

Karnataka uses the higher intra-state threshold of ₹1,00,000 (along with Delhi, Kerala, Rajasthan, Tamil Nadu and Uttarakhand). Other states use the default ₹50,000 threshold for intra-state moves.

Yes. The "sub-supply type" should be set to "Sales Return". The consignee on the return EWB is the original supplier. Sales returns above the threshold require an EWB just like a forward supply.

E-invoice is the digital tax invoice with IRN, mandatory for B2B supplies above ₹5 Cr turnover. E-way bill is the transport permit for moving goods, threshold-based. An e-invoice often auto-generates the e-way bill Part A; Part B still needs vehicle details.

Yes. The EWB portal supports bulk JSON upload via API or the bulk-generation tool. For high-volume despatch operations, integrating your ERP / TMS with the EWB API is the right approach. Manual generation does not scale.
