Your relationship with the company is probably governed by a contract. The terms of the contract, supplemented and interpreted by applicable law, determine what each of you is required to do. The way to answer your question would be to look at the provisions of the contract related to payment, and see what it says about timing. A payment is due under a contract according to what the parties agreed to. If a term was not specifically agreed to, then a number of different things could determine the answer, but in general if payment is by mail then it must be postmarked by the due date.
