Now in my 5th year, several times have I added a late fee to the bill once it becomes past 60 days due. Obviously in some cases I never got paid. But in every single other instance where a check finally arrived at the last minute (after they got the final letter before I send it off to a collection agency), nobody has ever paid the late fee. While most simply wrote the check for the original amount due, others were so smart that they added a smaller amount, as if to say that it is at their discretion to decide what the late fee should be. Either way it makes no difference, I got skru'd in part or whole out of the late fee. Yes, every single time lol. Over the years this frustrated me more, and more. The late fee exists for a reason, it's not just a deterrent but it also covers my time spent chasing / collection costs. So this last year I decided to re-word my final letter to include the phrase 'unless you pay the full amount due of $xx.xx [original + late fee], I have no other choice but to send this to collections' blablabla... And yes, I ALWAYS send a letter before that to inform them of this upcoming event AND the actual amount of the late fee (so nobody can say they were never told)... And for those who pay at the 2nd-last letter, no late fee (this I can live with). Of course, you know it: Once more someone got to that point (way over 60 days past due), and sure enough, they sent the original amount + $10 (my late fee is $45). So the next step is, once I clear the check through the bank, I'm sending the remainder to collections with a $35 balance. What would you do / have you done to alleviate this issue? Do any of you guys ever collect (read: actually receive lol) the late fee?
