Automated late attendance fees are fees that automatically get charged to a child when the child's attendance record has a time out after the end time of their class. To be effective, the class/schedule should have an end time set up, either in Settings > Classes > Schedule > edit schedule, or in the child's enrollment.
To set up automated late fee you will need to go to Settings > Billing > Setup Automated Late Attendance Fees. From here, enter in the late fee amount and the interval and number of minutes for the grace period. If you do not wish to to give a grace period, just input 0. Click Save when you are done. You can also set up Advanced settings where you can apply further charges based on additional criteria.
The default is that this automated late fee will not apply to the children. You will need to go into their profiles > Scroll down to their enrollment > Click the edit pencil. From here, you will need to click Late Attendance Fee from the drop down(s) beside Late Fee.
