Hello Gordon,
Yes, Adagio Ledger also clears the year's detailed transactions when year end is run. Normally, a client will make a copy of the Ledger database in another subdirectory to store the details for inquiry purposes.
Adagio Ledger's Financial Reporter is industry leading. You can drill from a financial statement value, all the way to the posted transaction detail, while maintaining the ease of drag-and-drop financial statement simplicity of design.
One advantage that Adagio offers, is the ability to "test drive" the application with your own data. Installing Adagio does not preclude a move to Advantage at some later date should its feature set seem more attractive. If we were to maintain multiple years of historical detail, how many would you like?
