This transaction will reduce both the cash and accounts payable sheets.
In accounting, an account payable is any contribution from a debit party, which appears as a result of a purchase of goods or services in terms of credit, to a creditor party. The reduction of this sheet is due to the fact that with the payment, there are less accounts payable.
