Hello RT,

To match unmatched transactions for Open Item Customers, create a 0.00 cash entry and select the positive and negative invoices.

To match unmatched transactions for Balance forward customers, you will have to change them to Open item and then create a 0.00 cash entry and select the positive and negative invoices.

If the Customer balance nets to 0.00, you may also use Write-off to write off Balances from $0.00 to $0.00.
