In the edit Appt Book view options, include Patient Balance (options for First Name, Last Name, Phone, Chart #, etc) in the Display Options. This way, whatever the Pt Balance is (credit or debit) from the Ledger can populate directly on the appt block. There needs to be some kind of indicator directly on the appt book/ appt block of who has a balance/how much debit balances need to be collected for the day. Ex: schedule has 10 patients that, in total, owe $5000.
