Abstract: A payment processing network operator obtains, from customer service providers, a first plurality of messages specifying a plurality of bill payments to a plurality of biller entities. Said first plurality of messages specifies, for each of the bill payments, an amount and an intended one of the biller entities to be paid. Based on the first plurality of messages, the operator of the payment processing network dispatches, to the plurality of biller entities, a second plurality of messages to initiate the plurality of bill payments. The operator of the payment processing network obtains data that specifies when at least some of the first plurality of messages are to be obtained and/or when at least some of the second plurality of messages are to be dispatched. Obtaining the first plurality of messages and/or scheduling dispatching the second plurality of messages are carried out in accordance with the data.
