What is Peppol?
Peppol is a pan-European e-invoicing framework used in 40+ jurisdictions. It standardises the exchange of structured invoices between Access Points using AS4 and UBL.
Learn about Peppol →What is an SMP?
A Service Metadata Publisher (SMP) advertises which documents a Peppol participant can receive, and where. GoRoute operates a managed SMP-as-a-Service with REST APIs.
