Hello, ktuva.

I'll shed some light on the status for the projects in QuickBooks Online. 

We can only set the project status as Completed, Canceled, or In progress. You can set it as "In Progress" in the meantime if you think there will be unexpected expenses after completing it. 

Alternatively, you can add some notes if you don't want to change the status. Simply open a project, then click the Edit button.

From there, you would want to add something like "Added unexpected expenses" or similar. 

Though, adding more project status would make the progress more flexible in terms of unexpected changes to it. This feature might be added in the coming updates. 

I suggest checking out our QuickBooks Blog from time to time for news about QuickBooks Online updates. 

Find out more about the Projects feature from this article: Set up and create projects in QuickBooks Online.
