Do all my suppliers have to be subscribed to the platform?

When you add a supplier as a Business Relationship they receive an invitation to confirm the connection - just like a social network. Business Relationship must be confirmed before you can view their certification information on the platform.

Both parties must have the appropriate subscription to ensure they can add a new Business Relationship. The first three connections are free without subscription.

No. This is an additional service for certificate holders 

provided by GTS and PEFC. It is entirely voluntary.
