Abstract: A system and method for providing an efficient and robust interface that allows banking transactions to be processed by an online banking system and third party accounting software packages via a single user point of entry. The system is configured to receive a transaction request from a third party accounting software, the transaction request including one or more transactions; verify, based on information stored in a first database, that the transaction request is from a valid source; store information regarding the one or more transactions from the transaction request in a second database; process the one or more transactions; and provide a response to the third party accounting software indicating a status of at least one transaction in the transaction request.
