I charge $20 late payment fee. Payment is due every 2nd Friday at drop off. Late fee begins at noon same day and then continues until payment is received. If they pay late they risk being terminated. I don't mess around. I rely on my money. I do not wait for it either. I had 1 mom go on holidays and forget to leave post dated cheque. After having to make other arrangements to get money sent to me or risk paying late fee she didn't let it happen again. I have a post dated cheque for next pay when they are away!

I would get tough and get tough quick. They need to take you seriously and you need to not allow this to happen.
