Implementation Notes

Pure Peppol, no local customization. Luxembourg uses standard Peppol BIS 3.0 with no national CIUS, making it one of the simplest markets to support if you already have Peppol integration. MyGuichet.lu is available as a fallback for manual submission. CTIE (Centre for Information Technology of the State) operates the central authority. The Ministry for Digitalisation serves as the Peppol Authority.
