How to Apply a Change Order

Written by ZevBit Software

You can apply a Change Order when you need to update a project’s estimate after it has already been approved.

This is typically used when the project scope, pricing, or requirements change. Applying a change order ensures that your invoices and financial data stay aligned with the updated agreement.

Before You Start

Make sure:

  • The project has an existing signed proposal

  • You have permission to access both the Invoices and Estimate modules

Steps to Apply a Change Order

  1. Go to the Invoices module

  2. Click the Customer Name / Project Name to open the project

  3. In the Project Invoicing page, click Change Order

  4. You will be redirected to the Estimate module

  5. Update the estimate as needed

    You can modify:

    • Pricing

    • Line items

    • Scope of work

    • Materials or services

  6. You can save the changes as a draft, send them to the customer to sign, or approve them internally. If sending to a customer, the system will prompt you to select which change you want to send to the customer. (In case you have more than 1 line item added)

  7. Adjust the payment term for this change order to your existing payment terms & select the desired option

  8. The system will show you what the payment terms will look like. You can edit the name of the change order. Click Confirm.

  9. The system will show you the updated Proposal document. Add your signature if needed. Then click "Send change order to customer."
