Interaction Flow in BBPS

To illustrate the interactions among these entities, consider a customer paying an electricity bill.

Step 1: Customer to Customer BBPOU

The customer logs into a mobile app (e.g., Paytm or their bank app).
They enter their bill details (e.g., customer ID or account number).
The Customer BBPOU requests the bill details through the BBPCU.

Step 2: Customer BBPOU to BBPCU

The Customer BBPOU forwards the bill fetch request to the BBPCU.
The BBPCU identifies the appropriate Biller BBPOU responsible for the biller (e.g., XYZ Electricity Board).

Step 3: BBPCU to Biller BBPOU

The BBPCU routes the bill fetch request to the identified Biller BBPOU.
The Biller BBPOU retrieves the bill details from the biller.

Step 4: Biller BBPOU to BBPCU

The Biller BBPOU sends the bill details (e.g., amount due, due date) back to the BBPCU.

Step 5: BBPCU to Customer BBPOU

The BBPCU routes the bill details to the Customer BBPOU.
The Customer BBPOU presents the bill details to the customer for payment.

Step 6: Payment Flow

The customer initiates the payment (e.g., via UPI, debit card, or net banking).
The payment information flows back to the BBPCU from the Customer BBPOU.
The BBPCU forwards the payment details to the Biller BBPOU.
The Biller BBPOU updates the biller about the payment and confirms the payment status back to the BBPCU.

Step 7: Confirmation Flow

The BBPCU sends the payment confirmation to the Customer BBPOU.
The Customer BBPOU provides the confirmation to the customer (e.g., a payment receipt).
