1. From the Configuration page click Default Accounts
  2. Highlight Unapplied Payment
  3. Enter the account number to use when posting payments prior to making applications

    Note: The unapplied payment account is limited to a single account and masking is not applicable.

By defining a default account for unapplied payments, you designate an account that automatically appears on new payment records. This account helps to ensure that unapplied payments are held in an account separately from the AR summary account. This improves reconciliation and helps you determine the unapplied payment balance.
