Hello there, drdonerite.
There are many ways to locate previously created estimates. One of them is to use the Search function.
- Click the Search function (magnifying glass icon).
- You'll see the estimate under the RECENT TRANSACTIONS.
You can click View more to see more of the list.
- Click Advanced Search if necessary.
We can also use Estimate window to see the previously created estimates.
- Click the + New button in the upper-left corner and select Estimate.
- Click the clock icon before Estimate #.
- From there, you'll see the previously created estimates.
Another option would be to use the Audit Log. You can use this link for reference: Use the audit log in QuickBooks Online.
Once you've found the estimate, you can already create an invoice from it.
Let us know if you need anything else. Have a great day!
