Computerized accounting systems and methods

A computerized accounting system, comprising:

• a host accounting system, where the host accounting system stores, in a general ledger database, transaction data representing financial transactions that occur over a time period;
• an overlay system, where the overlay system
• enters overlay adjustment data representing adjusting journal entries related to the transaction data stored in the general ledger database, and
• stores the overlay adjustment data in first and second overlay data sets, where
• the first overlay data set contains the overlay adjustment data related to the transaction data in the general ledger database at a first point in time during the time period, and
• the second overlay data set contains the overlay adjustment data related to the transaction data in the general ledger database at a second point in time during the time period, where the second point in time is after the first point in time;
• a host report system, where the host report system creates host reports based on the transaction data stored in the general ledger data set;
• and
• an overlay report system, where the overlay report system generates
• a first overlay report based on the transaction data stored in the general ledger data set at the first point in time and the overlay adjustment data in the first overlay data set;
• and
• a second overlay report based on the transaction data stored in the general ledger data set at the second point in time and the overlay adjustment data in the first and second overlay data sets.
