E way bill updates

Sir,

Since we need to deliver materials from Bangalore to Mumbai, we have informed our vendor to move the materials from Mumbai & he will be raising the E way bill for the same.

Now the question is do we need again to raise the e way bill, if yes, we will raise, but if no. do we have any circular for the same. Since most of our customer wont process our payments with our our E way bills.

Awaiting your valuable reply. 

Thanks

Aravind
