The amount that is reflected here can be one of two things. First it is a copay or prepayment that is not meant to be applied to the account's balance as it is not part of the open bills. The other case is that Simplee will sometimes place an amount here if what we receive back for a payment differs from what is already in the system.
For instance a payment is made in Simplee for $100. When this payment is sent back by the provider Simplee only receives $75, as maybe $25 was applied somewhere else and not sent back in the reconciliation. When this happens the only amount that will be applied to the account balance will be $75 as that was what was received in the files. However to make sure that the payments of $75 and $100 are not both being applied to the balance, the original $100 is marked as unapplied. This means it will not affect the account balance and it will then be placed in the “Copay/Pre Payments: (Unapplied payments)”.
