Abstract: A system to pay an invoice includes reception of a code and a payable amount associated with an expense, identification of a user associated with the code, presentation of the expense to the user, reception of an instruction to pay the payable amount, and determination of whether the payable amount is less than or equal to an approved amount associated with the code. By using a code associated with an appropriate user, an expense may be easily directed to a user authorized to evaluate and instruct payment of the expense.
