At the end of your fiscal year it is a very good idea to make a Special Archive backup of POSitive data. Click here for instructions.
One reason for making an Archive backup is to be able to determine stock counts and the value of your inventory at the end of your fiscal year. Because POSitive is a real time software program, changes to your inventory stock counts are ongoing and without an archive backup it is difficult to calculate stock counts on a specific day in the past.
