Hey guys. I'm redoing my estimates. I decided this year that I have to add a $10 late fee. I'm looking to get some ideas to the wording I should use. I bill once a month, usually on the 1st and give customers at least 15 days to pay. Now if someone doesn't pay by the 1st of the following month I want to add in the late fee of $10. Should I tell them if payment isn't received by due date they get the $10 late fee or should there be a little grace period. I'm looking for some ideas on wording that I can put at the bottom of my estimates.
