Add approved change orders to an invoice after a project begins. ## Before you start Add additional work after the estimate is accepted. Customer approval is required before it affects the invoice total. Additional work is available on invoices only. For pre-acceptance add-ons, use [Customer Accepted Options](/support/estimating/line-items-and-options/customer-accepted-options.md). ## Add additional work 1. Create an area or line item as an option.

The item moves to the **Pending Additional Work** section. {% hint style="warning" %} Pending items do not affect the invoice until the customer approves them. {% endhint %} ## Get customer approval Customers can approve the work in two ways: 1. For on-site approval, select **Option Approval Required**. The customer signs for the additional work immediately.

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://help.paintscout.com/support/estimating/line-items-and-options/additional-work-change-orders.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
