Payments on behalf of a plurality of payors to a plurality of payees are
facilitated using respective first data associated with each payor and
respective second data associated with each of those payees payable by
crediting via electronic funds transfer (EFT), such as by ACH transfer.
The respective first data associated with each payor includes payee
identity information for each payee designated by that payor, and could
for example take the form of a payee list for that payor. The respective
second data associated with each payee payable by crediting via EFT
includes payment information identifying a deposit account of that payee.
Information identifying a first of the payees and a deposit account of
the first payee is received by a payment service provider. The first
payee is not currently one of those payees associated with respective
second data, when this information is received. The payment service
provider stores a payee identifier for the first payee in association
with payment information corresponding to the received information
identifying the first payee deposit account as respective second data
associated with the first payee. After receipt of the information
identifying the first payee and the first payee deposit account, the
payment service provider determines that the respective first data
associated with a first payor includes payee identity information for the
first payee and, based on this determination, stores an indicator
indicating that the first payee is payable by crediting via EFT, in
association with the payee identity information for the first payee in
the respective first data associated with the first payor.
