Thanks for the quick reply Michel,

That's exactly the direction I was heading. Allowing the user the option to switch from business to business. Some of the steps I considered thus far:

1.) In order to help them ensure they have the RIGHT business, allow them to upload a business logo when registering their business and display that logo in the somewhere on their screens throughout the app.

2.) Allowing for no more than (2) folks per business to be assigned with Admin levels. I have only 3 levels available, admin, power user and user.

3.) Only the admin folks can add the everyday worker bees as authorized users or power users for a particular business.

My struggle, if you will, is determining the most efficient method of allowing them to, a. register as a new user (new installation), b.) setting business profiles.
