An invoice is a commercial document issued by a seller to a buyer, detailing the goods sold, the services rendered, and the amounts owed. It serves as a record of the transaction and is essential for various business operations.
Invoices play a vital role in accounting, inventory management, and financial planning. They provide a clear understanding of the terms of sale, including payment due dates and any discounts or penalties. Historically, invoices have evolved from handwritten documents to electronic formats, offering greater efficiency and automation.
