A sales invoice is a document that comes under the purview of accounting. It is prepared by the seller of goods or services and sent to the customer. This document records details of services/products purchased, the amount they owe, and the mode of payment. In addition to serving as a request for payment, a sales invoice also acts as proof of supply. This means that if there is a dispute or legal issue regarding the supply of goods or services, the sales invoice can be used as evidence to prove that the supply was made.
