When I started doing my own consulting, I realized that sometimes I would have to chase after a client in order to get paid. Luckily, it hasn’t happened often.
I did not expect the reverse to happen, but it did. I just had to send the following formal notice to someone who does work for me:
I am pretty sure that I owe you money. Would you mind terribly if I paid you?
And yes, this post is here to serve as a kick to the people in question.
