The right transfer rail depends on how urgent the payment is, how large it is, and whether the receiving bank participates in the chosen scheme. Every option below works with the IFSC AUBL0002665:

• NEFT — best for everyday transfers of any amount; settles in half-hourly batches around the clock.
• RTGS — best for transfers of ₹2 lakh and above; settles each transaction individually in real time.

• UPI — best for small peer-to-peer payments using a VPA; the underlying account at SION EAST is still linked to IFSC AUBL0002665.

For salary credits, vendor payouts and refunds, employers and merchants usually default to NEFT because of its zero per-transaction cost for retail customers and its 24x7 availability.
