Hi folks - do we have saved CSV import templates (csv files) in NetSuite somewhere? I am trying to setup a new company and need things like Chart of Accounts etc.

Not for ones that use the Import Assistant (the normal CSV import process) as far as I know. But if you drill down to the particular record type page(s) you're looking for from "Supported Record Types for CSV Import" SuiteAnswers ID 10008, there is often an import example. Don't know if that's really that much faster/better than just opening up the UI in one screen and creating your own template on another screen though.
