From Job Cost, click the Help menu, and either scroll through the help topics or search for "Import Estimates". You'll find the template specs and examples provided.  It's very straight forward.

You can also go to the knowledge base and search. The template is posted there.

Dale, did the sample template I sent work?

I am unable to locate the template via knoledgebase or the help section of job cost. Can you provide the template?

From within the Job Cost application, click "Help", "Help Topics", click on the "Index" tab, in the search box, type "Importing" and scroll down to "Estimates".  The panel on the right will contain an explanation of the process. Paragraph 2 in that panel contains a link to a description of the import file, and a link to an example of the CSV file layout.  The file can be built in Excel, and then saved as a CSV file.
