SEO Positioning: Different URL for different kind of users in the same website

SEO Positioning: Different URL for different kind of users in the same
website

I'm developing an eCommerce website, whose users can be of two kinds;
ordinary people and business. The difference between them are short,
business users has a special discount, so their prices are different; and
a couple more of minor changes compared to ordinary people.
My question is if it matter if this two users has the same URL for the
same modules, for example, if they are watching the catalog:
myapp.com/catalog
A business users could be:
myapp.com/business/catalog
I'm asking this question because of the SEO positioning; I need to know if
this makes any difference longer than making the same URL for two kind of
users.
Thanks.
