Clicking on the Patients' Records tab on the right, you will see the full list of patients, where you can sort them by the amount overdue and by the amount of services performed. On the left, you can see the personal data of the patient selected from the list, whose profile can be edited. You may also fill out this patient record if necessary.

To view the record of the patient selected from the list, you should click the "View Patient Record" button. 

You can also create a reminder for a patient. To do this, just click the "Reminder" button in the lower left part of the page and in the dialog box, specify what it is about and the timeframe for its relevance. After that, the previously created reminders for all patients will appear in the "Reminders" section of the main menu on the specified dates. (See the corresponding section of the manual)
