re: How to handle clients who don't adhere to your payment policy...

I have a similar payment policy, and I send the client a reminder email a month before the final payment is due. I state in the email and the contract that if the final payment is not received by the due date then the order will be cancelled and any payments will be forfeited. That usually keeps people on task. If not, I call the client for one last reminder a week before the due date. Those people usually pay immediately. I have not had a late payment since I started this policy. You have the power in this case, don’t forget that.
