From the Employer Dashboard and select Import.
You’ll find a link there to download your existing employers to a CSV file so that you know which column headings to use when you build your import file.
Upload your file, and a preview of the data will show.
If you’re happy with this, select the button to import the employers.
Any Employer Defaults you’ve set will be applied and the employers will be created.
Once you import the employer records, you can then import employees via one of the many methods available (CSV, FPS, etc.).
