Systems and methods for adding a payee to a user's list of payees in an online bill payment system provided by a financial institution. The online bill payment system accesses financial data of the user from a personal finance management application or a financial institution. The financial data is analyzed by a computer to identify payees of the user. The bill payment system determines if it has payment information for the identified payee, and adds the payee to the user's list of payees. Alternatively, the financial data may be accessed and aggregated by a personal finance management application and then analyzed by a computer to identify a payee. Then the identified payee is communicated to the online bill payment system, which adds the identified payee to the user's list of payees.
