We are a registered GST partnership firm in Hyderabad which is under state of telangana. I have a requirement wherin I would need to Purchase material from a party in Vijaywada ( Andhra pradesh)  and sell it to party in Tirupathi ( Andhra pradesh). Please advise how to enter this in GST waybill and kind of GST tax which will be applied.

 Is it 

GST( Intra state) - as material is only moving within state 

or

IGST( Inter state) - As a Firm from Telangana is procuring from a firm in Andhra pradesh and supply to other firm in Andhra pradesh. So purchasing would be between parties in different states and selling would be between parties in different states.  

I am kind of confused on how to get this done and how would accounting happen. Please advise. Thanks
