Many of us choose not to sign up with IC PRO because there is no discernible reason or benefit to providing our information to still one more on line entity. IC Pro does not create shopping jobs, schedule jobs or pay for jobs. Since they are not responsible for IRS reporting, there is no reason for them to have my SSN or a W-4. I do not work for them and in fact cannot work for them as they do not provide work for independent contractors.
When they first started there was a lot of fluff about signing up to 'show' that you were an experienced professional'. It would appear that primarily new shoppers have enrolled . . .
