Peppol certified Service Provider
A certified Peppol Service Provider is recognized by Open Peppol as a trusted access point to the PEPPOL network, meaning the provider meets all technical, security, and interoperability requirements for sending and receiving e-invoices and other business documents.

Peppol Production (PKI) certificate
**Software vendors with their own Peppol production certificate can send and receive Peppol messages directly over the network, without relying on third parties.
