We don't do any work with Ameristar, but we do have to follow the same procedure with other clients occasionally.  We strictly enforce our NET30 terms.  If the invoice is not paid by the due date we make a courtesy all and let them know that if the check is not received by the 45th day we will not be able to complete any more work for them until they are current.  We allow the extra 15 days to allow for delays in the mail - it happens.  However, if it takes more than 2 weeks for the mailman to deliver a check, its probably time to stop payment and reissue it.

It is funny, as you mentioned, that when they are told they going to get cut off, that check usually arrives pretty darn quick.

Best,
Robert A. Franco
