Trying to remove a payment in undeposited funds accout.

You're correct, @adreher1. Deleting a project is a permanent action. 

However, QuickBooks has the option to undelete your projects and to make them active again.

Here's how:

1. Go to Projects.
2. Click the Gear icon on the project page.
3. Tick the Show deleted projects.
4. If ever you don't see any deleted projects, refresh the browser.
5. Your deleted project will now show on the page.
6. In the Action column, click the down arrow and choose how you want to undelete the project.

Since the vendor is also inactive, you need to make it active. Follow the steps below.

1. Go to Expenses and choose Vendors.
2. Click the Gear icon on the vendor page.
3. Tick the Include inactive.
4. The deleted vendor will now show.
5. In the Action column, click Make active.

Then, proceed to remake the deleted transaction of the vendor within the project, and make a deposit to match the payment.

Additionally, you can also run a project report to get the profitability of a project.

Yes, that's right, @adreher1.

In QuickBooks Online (QBO), you can only restore those deleted projects with unfinished transactions. Those projects that were marked as "Completed" before they were deleted cannot be recovered again. 

If you want to bring back those projects you can recreate them instead. 

Then, to easily track the labor costs and profitability of your projects, you can use this article as a guide: Track hourly labor costs and profitability by project in QuickBooks Online.
