How do you guys set up your billing cycles and when do you expect payment by? I am getting tired of people paying when they feel like it. Most of my accounts pay on time or by the 15th but there are always the straglers. I used to say due upon receipt for payment terms. Now I have decided to do net 15. How do I get the client to pay attention to the terms of the bill in a tactfull manner? Just trying to get the cash to flow in more predictably.
