How to access business via URL directly

Getting Ready to purchase I download your server edition and like what I saw. I plan to use it for my Property management software but have a couple questions;

Can I via URL log directly into a particular business and when exit without go to manager home page?

With different user IDs, yes, assuming permissions are set correctly.

How?

@Sbutcher809 I suggest install free trial and set up users using this guide - https://guides.manager.io/9162

Then come back with the issue you are facing.
