Options for User Type Name between business and client

My first post here, still trying to get how to make a good question because most of the answers are a little subjective. anyway.

I'm having a issue close to this others, but none of the others has a answer that fit for me.

My problem is I have a app with Business and Clients login, but we really don't wanna use this names (B2C). So for business we are using Users Pro (or Providers) but for Clients still don't get the right name.

Already thought about members, companyName+Ers. And "user" I'm trying to avoid because the Providers are users to.
