My wife does all of our paperwork and billing from home and it is a lot of work but she is good at it. She also comes out and works with me when time permits for her. She mails all bills and letters from our mailbox, ya know the type where you put the flag up and the carrier takes the mail. Our route is usually not done by a uniformed postal worker in the little white truck, ours is a private vehicle and what I believe to be contractors that work for the postal service. My point is this, within the last couple of months we have had more than our share of customers who have been late in paying their bills. Sometimes it is more than a month late. These are long time, good customers and they never had trouble paying. Since they are good customers we usually wait until that second billing period and my wife will insert a polite note saying that we have not received their payment. We do not institute a late charge. We are slowly learning from more than one customer, 4 to be exact, that they never got their bills from us. We have also found out that certain payments that we make have been either lost or delivered late and no we are not deadbeats with our payments. I know the bills were printed, stamped and put in the mailbox. We don't have trouble with mail theft so I am positive that the mail system has a flaw and I think I know where and how. I watch these contractors who I believe are at fault. They will take the mail and throw it to the back seat of the car. There is a bin there but I have seen the mail just tossed to land anywhere in the back. I do not know what happens when they get to the post office but it is obvious something is not working right. Talking to the post office is like talking to your television so we have changed our billing practices. Now all bills and critical mail is taken directly to the post office. This still doesn't guarantee a flawless delivery but it cuts out the contractor who does seem to be a great part of the problem to me. It is a lesson learned and I am also glad that we didn't jump the gun and assume that our good customers have become bad. There is always a little more to the story. Take care.
