What is a Peppol SMP?
An SMP (Service Metadata Publisher) is a directory that stores the recipient's metadata, which documents they can receive and which Access Points they use.
When do you need an SMP?
For companies that only send, an Access Point is sufficient. An SMP is necessary for any organisation that receives documents.
SMP - exchanging documents via the Peppol network
Document exchange via Peppol requires both an Access Point and an SMP service. The SMP ensures that the organisation can be found in the network and is required for receiving documents. When sending documents over the network, the SMP service is required for receiving status messages, as the recipient has to send back a document with the status information the sender has to be traceable.
