Late Fees are tricky. I had to deal with Indiana University Medical Center which initially ordered one unit. Then a couple months went by. When I gave them a friendly reminder (they were offering a formal study of our product, so I decided not to rock the boat) they upped the order to 3 units. Then the W-9 form came and went; then I cound out more and more hoops and forms to become a formal vendor with IU. So the who thing took 3 and a half months and created a large gap in our cash flow. I covered it, but that meant falling behind and adding debt.
So I promised no more of this. If we work with any kind of institution, I ask about anything to do with timeline and payments and I hold them to it. So far late fees have no become necessary.
I recommend you do the same for your business. If they have any trouble paying on time, make sure they understand they must call and talk to you immediately or a late fee will be assessed. Say it up front and there are no issues or arguments later.
