Service Provider is a new user type on the platform. By definition, Service Provider provides a service for the buyer or seller.
Currently, domain admin will create a company, from admin panel as a 'Service Provider' and mark it as either servicing the buyers or sellers. Once the company is created, a mail is sent to the primary contact with the info.
A Service Provider will initially have limited functionality but we will build on the capabilities in near future, matching those enjoyed by a seller profile.
