invoices

An invoice is a formal document that a seller issues to a buyer, detailing the products or services provided, their quantities, and the total amount due for payment. It typically includes payment terms, such as the due date and accepted payment methods. Invoices serve as a record of the transaction for both parties, helping to track sales and expenses. They are essential for accounting and tax purposes, as they provide proof of what was sold and how much is owed. Overall, invoices ensure clear communication and accountability in business transactions.
