Which document is used to track what services or items have been delivered to a client?

The document used to track what services or items have been delivered to a client is the delivery receipt. This receipt serves as an acknowledgment from the client that they have received the specified goods or services, providing a clear record of the delivery transaction. It typically includes details such as the date of delivery, the items delivered, quantities, and sometimes even the condition of the items upon receipt.

While an invoice is associated with payment and may list items and services rendered, it does not specifically confirm delivery. A sign-off sheet primarily serves as a record for the client’s approval or acceptance of work performed and isn’t focused solely on tracking deliveries. A work order often details the tasks to be completed or services to be rendered rather than tracking what has already been delivered. Hence, the delivery receipt is the precise document that captures delivery details and confirms receipt from the client's perspective.
