A freight invoice is a document issued by a carrier or freight company that details the charges for transporting goods. It includes information such as the shipment's origin and destination, the type of cargo, and the total cost of shipping. This invoice serves as a request for payment and is essential for both the shipper and the carrier to keep accurate records. Freight invoices typically include terms of payment, due dates, and any applicable taxes or fees. They help businesses track shipping expenses and ensure that payments are made on time, facilitating smooth operations in the logistics and transportation industry.
