Why use contracts? Withhold funds for services rendered instead.
Was OK until they upgraded PLESK. CustServ told me I had to pay more to control my account. 3Ess would not credit me for unused service because they gave me the option to upgrade for additional $$. Not worth war for $64 but I can tell my story all day!
