Unapplied Cash is a separate customer balance intended to hold payments that are not ready to be applied.
At the time a Payment is saved, if the Payment Amount entered in the top portion of the screen exceeds the total of the selected Invoices in the grid, a question appears asking if the difference should be put to Unapplied Cash. Choosing Yes places the balance in Unapplied Cash. No returns to the Payment on Accounts screen where changes may be made to the Payment Amount or the selected Invoices.
Unapplied Cash is a credit balance and is held as a separate balance at the Customer's Monthly Balance tab. Like Prepay, this balance is generally a credit balance but is displayed as a positive number.
The Unapplied Cash balance may be applied on a Payment by utilizing the Use U/A Cash option at the Payment on Accounts screen.
