Odoo Configuration electronic invoicing 2026 : complete guide PA
By Laurent Blanchet, President of Advanced Conseil — certified Odoo partner accounting firm, based in Levallois-Perret. Advanced Conseil has been supporting SMEs in complying with Odoo electronic invoicing since 2024.
Starting from September 1, 2026, all VAT-registered businesses in France will need to be able to receive compliant electronic invoices via an Approved Platform (PA). For SMEs, the obligation to issue follows on September 1, 2027. The PDF format sent by email will no longer have any legal value.
« Le niveau de préparation des PME reste très hétérogène. Beaucoup savent que la réforme arrive, mais peu mesurent réellement son impact opérationnel. La confusion la plus fréquente est de penser que la réforme se limite à envoyer des factures en PDF structuré — alors qu'elle implique une refonte complète des flux de facturation entre votre ERP et votre PA. »
Laurent Blanchet
What the reform concretely imposes on your SME
Key dates to remember :
— September 1, 2026 : mandatory receipt for ALL businesses
— September 1, 2027 : mandatory issuance for SMEs and micro-enterprises
What many do not know: the receipt obligation applies from
September 2026 for everyone.
If one of your ETI clients sends you
an electronic invoice and you are not equipped to receive it,
you cannot account for it — and therefore cannot pay it.
Penalties for non-compliance: €50 per invoice not issued
in the correct format, capped at €15,000 per calendar year.
What is a compliant electronic invoice?
It is not a PDF sent by email.
It is a structured file
— Factur-X, UBL or CII — that must transit through an
Approved Platform (PA) certified by the DGFIP.
Odoo natively integrates the electronic invoicing in its Accounting module. For companies already equipped with Odoo, compliance does not require changing tools or integrating a complex external solution.
A simple PDF invoice will no longer be compliant.
- Native Factur-X generation - le format recommandé pour les PME françaises is automatically generated from Odoo 16+ without additional modules
- Odoo est une PA certifiée par la DGFIP, permettant l'émission et la réception directes depuis votre ERP, gratuitement et sans limite de volume
- Integrated Peppol connection - for international exchanges and UBL formats, Odoo is already connected to the European Peppol network
- Zero cost per document- unlike other PAs that charge per unit (€0.05 to €0.50 per invoice), Odoo offers unlimited access in the subscription
- Total accounting integration - received electronic invoices are automatically imported as drafts in the purchase journal for validation in 2 clicks
The decisive argument for Odoo users Your teams continue to work in the Odoo interface they already know. Zero additional training on a new tool, zero double entry, zero interface to maintain.
Status of Odoo PA certification in France
Odoo is an Approved Platform (PA) with the DGFIP. Odoo allows French companies to issue and receive electronic invoices directly from their ERP, without going through a third-party PA.

The 4 new mandatory mentions to configure in Odoo
As of September 1, 2026, all issued invoices must include 4 new legal mentions:
Mention obligatoire | Description | Paramétrage Odoo |
Catégorie d'opération | Distinguer : livraison de biens / prestation de services / mixte | Champ à créer dans le formulaire de facture — Advanced Conseil configure les valeurs |
Option TVA sur débits | Si l'entreprise a opté pour la TVA sur les débits (et non sur les encaissements) | Case à cocher dans Comptabilité → Configuration → Paramètres TVA |
Adresse de livraison | Obligatoire si différente de l'adresse de facturation | Champ existant dans Odoo — à rendre obligatoire par règle de validation |
Client PA identifier | SIRET ou identifiant PA du destinataire pour le routage automatique | Champ personnalisé à ajouter dans la fiche client |
Point of attention: These 4 mentions must be present in the generated Factur-X XML file, not just visible on the PDF. Advanced Conseil checks the presence and compliance of these XML tags during the testing phase.

FAQ
Electronic Invoicing on Odoo
Yes. Odoo 16, 17, 18, and 19 natively generate the Factur-X format EN 16931, recommended for French SMEs. Odoo is officially listed as a future approved PDP operator by the DGFIP. In the meantime, Advanced Conseil is deploying the transitional solution: generation of Factur-X in Odoo + transmission via a certified partner PDP.
No, if you are on Odoo 16, 17, 18, or 19. Factur-X is native in these versions with French localization. If you are on an earlier version, an update is necessary — Advanced Conseil assesses feasibility during the initial diagnosis.
Between 1 and 3 business days for complete setup, depending on the complexity of your configuration: number of journals, specific VAT cases, subscriptions, deposits. Testing and training are added to this timeframe.
Yes. As soon as your supplier issues via any certified DGFIP PDP, their invoice reaches you in Odoo in the format Factur-X or UBL — regardless of the solution they use. This is the principle of mandatory interoperability between all approved platforms.
