right now my contracts have late fees, which are supposed to apply, after payment is only one day late. i have been using a "grace period" though , meaning if payment is due on the first, and i get it by the 5, 6th, i don't add a late fee. next season i plan on strictly enforcing late fees. i'll have a 3 day "grace period" , after that the late fee WILL BE ENFORCED, i don't care if you're the president. so tell me, how strict are your late fees, and if they are strict, do people cancel when you enforce them?
