I have a policy that is in every contract that says "Payments are due by the 15th of every month. If the balance is not paid in full by the 15th, the client may be subject to a late fee of $10." Now with that, it's past the 15th and a couple are now late. Should I be chasing the payment or just add that balance to the next bill along with the late fee? Chasing the payment seems like a waste of time considering one is for $61.25 and the other is $54.38. How do you guys handle these situations?
