I thought someone mentioned before a software they used that made it very easy to add late fees (or it automatically added late fees because parents had to sign in/out). Does anyone know what it's called?
I think if you're more timid or soft spoken, that may be an easier way to address it - use weekly invoices and have the late fee show up there.
But I don't know how easy that software would be to customize
(for example, an early closing or families with different hours each day).
