View my cost through estimate?

Hi there, @rufunky.

We can use progress invoicing to split an estimate to many invoices. Let's ensure that the cost and price are in the item setting. 

If you haven’t already, turn on progress invoicing. Here's how:

1. Go to the File menu and select Switch to Single-user mode.
2. Click the Edit menu and select Preferences.
3. Choose Jobs & Estimates from the list of menus.
4. Select the Company Preferences tab
5. Tap Yes in the DO YOU CREATE ESTIMATES? section. Then tap Yes in the DO YOU DO PROGRESS INVOICING? section.
6. Click OK to save and close your preferences.
7. If you need to, go back to the File menu and select Switch to Multi-user mode.

Once you've done, you can now create an invoice from your estimates.

Then, we can run the Job Estimates vs. Actual Detail report, This shows how your company's estimated cost and revenues for a job and compares them for each of the items you billed.

1. Go to Reports.
2. Click Jobs, Time & Mileage.
3. Choose Job Estimates vs. Actual Details.

Also, you can customize the Job Estimates vs. Actual Details report to show other columns and information you wish to include: Customize reports in QuickBooks Desktop.
