List four documents used to cross-check before authorizing any payment in any purchasing department.

1. Purchase order: A purchase order is a document issued by a buyer to a seller, outlining the details of the products or services to be purchased. It serves as a contract between the buyer and seller and should be cross-checked to ensure that the payment aligns with the terms and conditions outlined in the purchase order.

2. Invoice: An invoice is a document issued by a seller to a buyer, requesting payment for goods or services provided. It includes details such as the quantity, price, and description of the products or services purchased. Before authorizing any payment, the invoice should be cross-checked to ensure that the amount being requested matches the agreed-upon price and that the goods or services were received as specified.

3. Receiving report: A receiving report is a document that confirms the receipt of goods or services by the purchasing department. It includes details such as the quantity, condition, and quality of the items received. Before authorizing any payment, the receiving report should be cross-checked to ensure that the goods or services were received in good condition and that they match the details outlined in the purchase order.

4. Vendor contract: A vendor contract is a legally binding agreement between a buyer and seller that outlines the terms and conditions of their business relationship. Before authorizing any payment, the vendor contract should be cross-checked to ensure that the payment aligns with the agreed-upon terms and conditions, such as payment terms, pricing, and delivery schedules.
