Billing Process

Raise E-way bill to send your goods to the job worker first. E-way bill is mandatory for job work irrespective of the value of goods transported.
Raise another E-way bill when your goods are ready to be transported to the buyer directly from the job worker. Either you or your job worker could do this. However only you can raise invoices in both the cases.
A separate invoice for job work will be raised by the job worker.
So two E-way bills and three invoices.

As per Notification 12/2018 CT : No Eway is required if the consignment value is less then 50k & consignment being send to job worker within state

Now , As to above if the material is less then 50k then send the material to Job worker on Delivery Challan (Without Eway)

And if the consignment value is more then 50k , then Genrate Eway on Delivery Challan to Job worker.
To get back the material from Job work again will deliver on genrating Eway on DC
