What's the difference between and "Employer Representative" and an "Added User"?

An “Added User” is someone employed by your company or business who has been granted access to your MiWAM account to submit, view, change information on your behalf. 

An “Employer Representative” is a third-party provider such as an accountant who is not an employee of your company. The Employer Representative requires a Power of Attorney to act on your behalf and they will be required to add you as a client through their MiWAM account.
