I have 10 day billing sent out on first of the month. Late fee 1.5%. I usually don't apply the late fee if they pay w/in the month. Most of our regulars pay w/in a week of receiving the bill - I have one that is bad about it and they are a business and I tack on the interest. You would think they would be better about paying. I usually have to send someone over there to collect. Hubby just went over there two weeks ago to collect on last years late balance from August - he told them that this crap had to end. Trust me they do not want me to come over there. For those of you that know me, I would be much more direct. For that account, I would like to see prepay or something. I dumped an account last spring after 4 years of servicing them bc they were sooo slooow in paying and they were also a business - a restaurant! I have taken two accounts to court for non-payment. Won the first one and the second was settled out of court for full amount, legal fees but no interest. A third late account moved on me, but I found her and she paid. Below I have posted what is on my bills..."Net due 10 days $$$...Accounts past due subject to 1.5% interest, all collection and legal fees, and discontinuation of service." Are you having payment issues??
