Abstract: A method for providing bookkeeping or accounting electronically. More particularly, this invention relates to a system or method for creating a reconciled set of electronic books by firstly introducing and integrating an accounting classification code or codes into the transaction data routinely captured by financial institutions at the time of the financial transaction to form a data aggregate on the financial institution server; the access by and transfer to the server of a person, business or entity, or a service provider authorised by the person, business or entity, of those data aggregates; the processing of that data into a form or state compatible with the operating requirements of a bookkeeping or accounting program used to prepare the financial records of the person, business or entity and the transfer of the processed data into the program ledger, journal or cash book to produce a set of electronic books for a period.
