I am drafting a contract term that would tell clients their final payment is due 10 days prior to the event. Should the sentence read:<br/><br/>"Event balance is due no later than ten days prior to your event..."<br/><br/>or<br/><br/>"Event balance is due no less than ten days prior to your event..."<br/><br/>???<br/><br/>I think of "later" in relation to time whereas "less" in relation to quantity, but I can't seem to locate a correct answer.<br/><br/>Thank you for your help!
