I just received payment on an invoice I submitted exactly one week ago. I love it when this happens, because so often we writers have to wait and wait and wait for our checks to arrive. This particular client always gets the check in the mail super fast … even though our agreement is something like net 30. The fact that they don’t make me wait and wonder encourages me to continue working for them, even though they don’t pay as much as some other clients. A smaller check that arrives in a timely manner is, imho, better than a larger one that arrives six months late.
