In order to avoid the current complexity, it would be very convenient to have all persons merged into one module:

• The "contacts" module should list all users, workers, suppliers, customers, etc.

• Each person in the module should be assigned to one or more "roles" (e.g. "supplier", "employee", "customer", etc.).

• A person (contact) should by default be a new Zoho user with a free plan (as it is the case of users, which should be merged into contacts). If someone is a customer or supplier of several companies, they should be able to log in to their single Zoho account.

This solution requires a review of some of the current concepts, but is, in my opinion, a necessary step forward for the future development of the Zoho ecosystem.
