1) no pay no stay. If my clients don't pay then care is suspended until their tuition payments and late fees are paid in full. Payment is still due for days missed due to suspension.

2) $50/day late fee. If I don't get paid by 8:00am every 2nd Thursday I charge them a $50 late fee. If I still don't have it by 8:00am Friday it is another $50 late fee ($100 in late fees) and so on. The late fee applies to every day late this includes weekends and holidays.

3) I have a secret face book group just for parents. On the Sunday or Monday of pay week I post: Just a friendly reminder that tuition payments are due anytime between now and 8:00am Thursday (Date).
on the Wednesday of pay week I post: Thank you to all who have already sent their tuition payments. For those of you who haven't please insure I have it no later then 8:00am Thursday (date) {tomorrow}, to avoid late fees.

Since I started doing all of this I haven't had any late payments.

If I don't have my payment in full (including late fees) within 7 days, care is terminated. Payments are still due or I either take them to small claims court or a collection agency.

If payment is late, but paid within 7 days, 3 times within one year, care is terminated.

I only accept EMT's (electric money transfers), this gives proof of payment emails, to both my client and to me.
