A sales invoice is a commercial document issued by a seller to a buyer, detailing the products or services provided, their quantities, unit prices, and the total amount due. It serves as a record of the transaction and a request for payment.
Sales invoices are crucial for businesses as they facilitate accurate billing, payment tracking, and tax compliance. Historically, invoices were handwritten or typed, but the advent of computers and accounting software has standardized their format, making them easier to generate and manage.
