How do I make a change order to an estimate on quick books online

Hi there, shawn8.

Creating a change order to an estimate is currently unavailable in QuickBooks Online (QBO). As a workaround, you'll need to manually enter the information of the change on the estimate. 

Our product developers are pushing through the envelope to improve the product to meet your needs. 

For now, I suggest checking our website for any enhancements and announcements through this link: The QuickBooks Blog.

I'll also update you in this thread if I hear any changes of the option that you're looking for.

Thanks for visiting the QuickBooks Community. Let me know in the comment section if you have any other concerns. I'm always here to help.
