An invoice is a commercial document issued by a seller to a buyer, relating to a sale transaction and indicating the products, quantities, and agreed-upon prices for products or services the seller had provided the buyer. It also includes the total amount due and often includes the terms of payment.
A business invoice serves as a record of the transaction, providing details of the goods or services rendered, their costs, and the payment terms. It is essential for businesses to issue accurate and timely invoices to ensure proper billing and payment processing. Invoices also serve as legal documentation, supporting financial transactions and tax reporting.
