Eway bill interstate supply

Hello everyone,

Suppose i am a registered supplier in Bangalore, Karnataka and will be sending my goods for final finishing job works to a registered person in Mumbai, Maharashtra and the goods will be supplied directly by the job works guy for some extra money for sending courier's from Mumbai, Maharashtra to the customers(registered or unregistered) in Hubli, Karnataka. The invoice for the supply made from Mumbai, Maharashtra to customers in Hubli, Karnataka will be raised by me from Bangalore, Karnataka.

Now my question is, in such a case who is required to raise EWAY BILL.

Should the job works guy in Maharashtra raise the EWAY BILL or should i raise EWAY BILL?

Please respond.

Thanks in advance :)
