B2G e-invoices in Luxembourg must use structured, Peppol-enabled processes. B2B remains voluntary but can use the same interoperable rail. Luxembourg uses Peppol as the common B2G delivery rail. Scheme 9938 is a routing identity and must not be treated as a VAT number; Dynafis validates the identifier type separately.
E-invoicing by country
E-invoicing in Luxembourg: mandates, formats, sending and receiving
Dynafis combines invoice validation, recipient capability, country profiles and evidence for Luxembourg. The permitted route is determined per legal entity, transaction and environment; Peppol is only one part of the overall process.
The profile distinguishes B2B, B2G and cross-border. Scope also depends on establishment, tax registration, recipient type, public procurement and cross-border context.
Relevant networks and portals include Peppol and CTIE. Dynafis validates Peppol BIS Billing 3.0, UBL and EN 16931 and the addressing schemes 9938 as separate concerns.

Accounting firms configure Luxembourg per client and legal entity. Credentials, provider accounts, documents and production approvals never inherit between clients; month-end checks remain traceable per legal entity.
