I am Supriya (94 Points)

If Mr.A of Bangalore buys goods worth 1 Lakh from Indore.
1.Is it required to have a E-way bill?
2.Who has to prepare the E-way bill?
3.The E-way bill compulsory from 1st Feb onwards is only for Intra State supplies. So is it applicable for supply from Indore to Bangalore?
