Enter the total amount of the payment in the Amount field, both dollars and cents. MacPractice will automatically format the entry as you type; there is no need to enter the decimal point. E.g., typing "12345" in the Amount field will be saved in MacPractice as "$123.45."
The Amount field may be located before or after the Reference Number field in the Payment Window, depending on your settings in Preferences.
After hitting the tab key or otherwise leaving the Amount field, the Remaining Amount will be populated with the full amount of the payment. The Remaining area will update as the Amount is applied towards open charges, whether through clicking the Apply to All button or manually applying the payment.
