Weproc PA Connect Blog : a plug & play ERP connector
Connecting your Business ERP or Tailor-made
Weproc PA Connect has been designed to meet a major challenge: most business ERPs, verticalized or custom-developed, do not have a native integration with an Approved Platform. Thanks to a plug & play approach, we ensure immediate interoperability with your existing environment, without complex redesign or long projects. Our expertise in integration allows us to adapt the solution to your flows, your management rules and your IT constraints.
Key points:
Compatibility with Microsoft Dynamics, SAP, Oracle, Sage and in-house ERP
Connection possible via REST API, secure SFTP or flat files
Rapid integration, without impacting your business workflows
Support from our technical and functional experts
Transforming Streams into Formats Recognized electronic invoices
One of the obstacles to electronic invoicing is the diversity of formats used by ERPs. Weproc PA Connect acts as a universal translator : your data is automatically converted to the standard formats required by the DGFiP.

The DGFiP’s Central Directory is the cornerstone of the e-invoicing system.

Real-time monitoring of business and technical statuses
Notifications in case of rejection or anomaly

FAQ – Electronic invoicing and Approved Platform
Preparing for the mandatory electronic invoicing reform? Find answers to the most common questions about Approved Platforms (PA), Factur-X, UBL, CII formats, the DGFiP directory, and ERP integrations (SAP, Dynamics, Oracle, or custom solutions).
What is an Approved Platform (AP) and why is it mandatory?
An Approved Platform (ex-PDP) is a solution recognized by the State to manage the exchange of electronic invoices as part of the reform of electronic invoicing in France.
From 1 September 2026, all companies must be able to receive electronic invoices. Large companies and mid-caps will also have to issue them by this date. The obligation will be generalized to all SMEs and VSEs on September 1, 2027.
Without a connection to an AP, invoice flows will not be able to flow properly, leading to rejections, late payments and a risk of tax non-compliance.
What e-invoice formats are supported?
Weproc PA Connect supports the three formats recognized by the DGFiP :
-
Factur-X (PDF + XML),
-
UBL (Universal Business Language),
-
CII (Cross Industry Invoice).
These formats are based on the European standard EN 16931.
Our solution automatically converts your native flows (from ERP, flat files, APIs) to these standards and performs syntactic and business checks to guarantee zero technical rejection.
How does integration work with an ERP like SAP, Microsoft Dynamics or Oracle?
Most ERPs do not have a native connector to an AP. Weproc PA Connect acts as a universal connector :
-
Data ingestion from the ERP via REST API, SFTP, webservices or flat files.
-
Automatic mapping of data to compliant formats (Factur-X, UBL, CII).
-
Secure transmission via the DGFiP Directory to send the invoice to the right recipient.
-
Real-time return of statuses (acknowledgement of deposit, receipt, acceptance, rejection, payment) directly in the ERP.
Thus, we provide bidirectional ERP ↔ PA integration.
Can you connect a custom-made ERP or an in-house one?
Yes. In fact, it’s our specialty.
Weproc PA Connect includes an Adapter Kit that allows you to connect any in-house ERP thanks to:
-
open and documented APIs ,
-
exchanges via secure SFTP or flat files (XML, CSV, JSON),
-
A flexible mapping engine to align your data with standardized formats.
This allows CIOs to avoid a costly overhaul and keep their system in place while becoming reform-compliant.
How is the security and compliance of exchanges ensured?
Security is at the heart of Weproc PA Connect:
-
Cloud hosting in France, GDPR compliant.
-
End-to-end TLS/HTTPS encryption.
-
ISO 27001 certification (information security).
-
Evidence-based archiving with built-in reliable audit trail.
-
Continuous updating according to regulatory changes published by the DGFiP.
What is the e-Invoicing Directory and how do you use it?
The DGFiP Directory is a central register that lists companies and associated approved platforms.
When an invoice is issued, Weproc PA Connect queries the Directory to identify the receiving AP (or PPF/Chorus Pro for the public sector) and routes the invoice securely.
This prevents addressing errors and ensures that the invoice always arrives at the right recipient.
What are the tracking and supervision features?
Weproc PA Connect provides complete visibility into the lifecycle of an invoice:
-
Real-time statuses: filed, made available, received, accepted, rejected, paid.
-
Centralized multi-ERP/multi-entity dashboards.
-
Notifications and alerts in case of rejection or anomaly.
-
Automated e-reporting of transactions and payments to the DGFiP.
This information can be viewed in a web portal or directly integrated into your tools via API
How are metadata and attachments managed?
Each electronic invoice can be enriched with metadata (order number, cost center, contract reference) and attachments (purchase orders, contracts, receipts).
Weproc PA Connect provides:
-
the centralised management of these documents,
-
their transmission to the addressees if the format allows it,
-
and their secure archiving for consultation and audit.
How can you avoid duplicates if an invoice arrives through several channels?
Weproc PA Connect integrates an anti-duplication mechanism based on several criteria (SIREN/SIRET, invoice reference, amount, date of issue).
This allows you to quickly identify if an invoice has been sent both by email, portal or ERP flow, and to avoid rejections or multiple payments.
What is the business model of Weproc PA Connect?
Our pricing is modular and tailored to the size and needs of the business:
-
Based on the volume of invoices processed (incoming/outgoing).
-
Options according to users (accounting, approvers).
-
Additional modules: ERP connectors, evidentiary archiving, advanced SLAs.
💡 Example: for a company dealing with 16,000 outgoing invoices and 4,500 incoming invoices, with 25 users (accounting/purchasing) and 60 approvers, the annual budget is calculated based on the volume and options chosen.
