Anyone have this problem: Send out your monthly bill and after 3 weeks, you get no check. So, with their next invoice I put on the bottom "Total Amount Due" and then give them their total outstanding amount. This summer, one customer called me on 3 seperate occassions telling me that my bill just couldn't be right and that this is way too much money. To make a long story short, it is THEIR problem that they let their bills rack up month to month. If you write out a check when you receive my invoice, then it will only be $120 instead of triple that. I dropped that customer due to the fact that he always let his invoices rack up and then had the ballz to call me and tell me that I was charging when I wasn't mowing. I think he just wanted to get a free mowing or two out of me. no sir.
