An invoice is a detailed record of a transaction between a buyer and a seller, listing the products or services provided, their quantities, and the agreed-upon prices. For instance, a construction company might issue an invoice to a client once a building project is complete, outlining the materials, labor hours, and other costs incurred during the project.
Invoices are crucial for businesses as they provide essential financial information and legal documentation for both parties. They serve as records of sales, supporting accounting processes, and can be used as proof of payment in case of disputes. Historically, invoices have evolved from handwritten documents to electronic and digital formats, making them easier to create, track, and manage.
