What type of document provides a breakdown of purchase details to customers?

A customer tax invoice provides a detailed breakdown of purchase details to customers, making it essential for both record-keeping and tax purposes. This document typically includes information such as the goods or services purchased, the quantities, the prices, applicable taxes, and the total amount due. It serves as an official confirmation of a transaction and is often required for the customer to claim deductions or for accounting purposes.

In contrast, a supplier invoice is primarily issued to the business by its suppliers and does not serve the purpose of informing customers about their purchases. A customer quote is a proposal that outlines potential sales before a transaction occurs, and a credit note is issued to rectify an error in a previous invoice or to process a return. Thus, the customer tax invoice is the most accurate document that provides comprehensive details on purchases, fulfilling both informational and compliance requirements.
