FAQ – E-Invoicing and Accredited Platforms
Preparing for the transition to mandatory e-invoicing? Find answers here to the most common questions about Accredited Platforms (PA), Factur-X, UBL, and CII formats, the DGFiP Directory, and integration with your ERP (SAP, Dynamics, Oracle, or custom-built).
What is an Accredited Platform (PA) and why is it mandatory?
An Accredited Platform (formerly PDP) is a solution recognized and registered by the French government to directly manage e-invoice exchanges under the new reform in France.
Starting September 1, 2026, all companies must be able to receive e-invoices. Large and mid-market companies must also issue them by this date. The requirement will be extended to all SMBs on September 1, 2027.
Without a connection to a PA (or the PPF), invoice flows will be blocked, leading to rejections, payment delays, and a risk of tax non-compliance.
Which e-invoice formats are supported?
WeInvoice PA Connect supports the three official formats recognized by the DGFiP (European standard EN 16931):
Factur-X (hybrid PDF containing an XML file)
UBL 2.1 (Universal Business Language)
CII (Cross Industry Invoice)
Our API automatically converts your native business data streams (from your ERP, flat files, JSON, etc.) into these standards and performs the necessary syntax and business rule checks to guarantee zero technical rejections from the tax authority.
How does integration with an ERP like SAP, Microsoft Dynamics, or Oracle work?
Most ERPs on the market do not have a native connector to an Accredited Platform. WeInvoice PA Connect acts as a universal connector:
Ingestion: Retrieves data from your ERP via REST API, secure SFTP, or flat files.
Mapping: Automatically translates data into compliant formats (Factur-X, UBL, CII).
Routing: Securely transmits the invoice to the recipient’s PA via the DGFiP Directory.
Statuses: Returns the real-time lifecycle (submitted, received, accepted, rejected, paid) directly to your ERP.
Can a custom-built or in-house ERP be connected?
Yes, that’s our specialty. WeInvoice PA Connect includes an Adapter Kit designed to connect any proprietary or legacy ERP using:
REST APIs that are open, modern, and documented.
Automated exchanges via secure SFTP (XML, CSV, JSON files).
A flexible mapping engine to align your internal data structures with tax requirements.
This allows IT teams to avoid a major and costly overhaul of their existing system.
How are the security and compliance of exchanges ensured?
Security is at the core of the WeInvoice PA Connect infrastructure:
Sovereign cloud hosting in France (100% GDPR compliant).
End-to-end encryption of data streams (TLS/HTTPS) and data at rest.
Targeted ISO 27001 certification for information security.
Legally compliant and evidential archiving for 10 years with a reliable audit trail.
Transparent and automatic regulatory updates in line with DGFiP changes.
What is the e-invoicing Directory and how do you use it?
The central Directory managed by the DGFiP is the official registry listing all French companies and their associated routing platform.
When an invoice is issued via the API, WeInvoice PA Connect automatically queries this Directory in the background to identify your customer’s receiving PA (or the PPF / Chorus Pro for the public sector) and routes the document accordingly. This completely eliminates addressing errors.
What are the tracking and supervision features?
Our solution offers complete and programmable visibility into your document lifecycle:
Real-time feedback of the 4 official DGFiP statuses (submitted, received, approved/rejected, paid).
Centralized dashboards (ideal for multi-ERP or multi-entity organizations).
Webhooks and instant alerts for anomalies or technical rejections.
Automated handling of e-reporting for your non-domestic or B2C sales.
How are metadata and attachments managed?
Each e-invoice can be enriched with metadata (PO number, cost center, contract reference) and attachments (purchase orders, contracts, supporting documents).
Weproc PA Connect ensures:
the centralized management of these documents,
their transmission to recipients if the format allows,
and their secure archiving for consultation and auditing.
How are duplicates avoided if an invoice arrives through multiple channels?
Weproc PA Connect includes a duplicate detection mechanism based on several criteria (SIREN/SIRET, invoice reference, amount, issue date).
This allows for the quick identification of invoices submitted through multiple channels (e.g., email, portal, and ERP stream) to prevent rejections or multiple payments.
What is the pricing model for Weproc PA Connect?
Our pricing is modular and tailored to your company’s size and needs.
