Managing Supplier e-invoices (Receipt & Compliance)
- 2026–2027 Compliant: mandatory receipt for all companies from September 1, 2026; phased rollout for issuance until 2027.
- Standards: Factur‑X, UBL, CII (EN 16931).
- PA/PPF & Directory connection; lifecycle status tracking.
- Configurable approval workflow, PO-invoice matching, Spend Forecast Plan (PDP), multi-site/multi-company, natively integrated e-invoicing.
Real-world example — Multi-site SME (Construction): Your suppliers send e-invoices (Factur-X/UBL); Weproc receives them via your PA, triggers the 3-way match (PO, receipt, invoice), and routes the approval to the site manager then the CFO. If there's a discrepancy, an exception task is automatically opened with the supplier. The result: zero re-keying, zero lost invoices, and on-time payments.
Why start with e-invoice receipt (mandatory in 2026)?
The first step towards compliance is the ability to receive electronic invoices. Starting September 1, 2026, all VAT-registered companies must accept e-invoices via the PPF (Public Invoicing Portal) or a PA (Certified Platform, formerly PDP). Issuance is being rolled out in phases: large and mid-market companies in 2026, SMEs/VSEs in 2027.
Beyond the legal requirement, structured receipt reduces errors, speeds up processing times, and prepares your business for pre-filled VAT returns (through status transmission).
Real-world example — Industrial mid-market company: You receive 2,000 invoices/month. Switching to structured receipt (Factur-X) cuts manual data entry in half and improves the reliability of cash-basis VAT accounting thanks to 'payment transmitted/cashed' statuses.

How Weproc secures the receipt of Supplier e-invoices
Weproc PA Connect = Your Certified Platform (PA)
Weproc PA Connect is the state-certified PA (formerly PDP) that routes, receives, and transmits your e-invoices and their regulatory data. Its official ‘provisional’ registration is listed by the DGFiP (step 1 of certification; completion of interoperability tests with the PPF finalizes the definitive certification). This guarantees a legal framework, compliance checks, and exchanges based on the national standard.
What a PA does—and what Weproc PA Connect does for you:
- Routing & receipt of e-invoices between senders and receivers via regulatory channels.
- Compliance checks (structured formats, required fields, business rules) before making invoices available.
- Transmission of tax data (e-invoicing & e-reporting) to the Public Invoicing Portal (PPF).
- Publication & updating of lifecycle statuses (mandatory/recommended/free).
From receipt to accounting integration: an end-to-end flow
As soon as a supplier issues an e-invoice to your SIREN number, the e-invoicing Directory verifies your details and routes the invoice to Weproc PA Connect (your PA).
The result: no more routing errors, with immediate availability for the correct company/entity.
Weproc PA Connect applies the French core controls (EN 16931 profile), verifies the presence of mandatory fields, and accepts standardized formats:
Factur-X (PDF/A-3 + CII XML, a Franco-German format compliant with EN 16931)
UBL and CII (European structured syntaxes)
These formats ensure interoperability and automation of procurement/accounting data.
Each invoice follows a standardized lifecycle. Weproc PA Connect issues and synchronizes statuses (mandatory, recommended, free), e.g.:
- submitted,
- made available,
- rejected (technical),
- refused (business),
- payment transmitted,
- cashed
to provide shared traceability and feed into the pre-filled VAT return.
In case of an anomaly (format, required fields, inconsistencies), the invoice is blocked with an explicit status. Teams are notified, the supplier is informed of the cause, and the workflow resumes upon correction—zero “lost” invoices.
Once made available in Weproc, you can trigger the configurable approval workflow (thresholds, delegations, parallel processing) and 2-/3-way matching (PO-GR-Invoice).
The goal: approve faster, reduce discrepancies, and secure the accounting export.
Invoices are allocated to the correct legal and budgetary scope. The Spend Forecast Plan (Weproc PDP) controls commitments and, if necessary, blocks approval if the budget is exceeded. Consolidated control at the group level, with ERP-ready exports.
Why receiving invoices via a PA is the right first step
- Guaranteed legal framework: A PA's role and responsibilities are defined by the administration; Weproc PA Connect performs these tasks and transmits data to the PPF.
- Up-to-date terminology & timeline: PA (formerly PDP) + Compatible Solutions; obligations from September 2026 (receipt for all companies), progressive rollout.
- Transmission of tax data (e-invoicing & e-reporting) to the Public Invoicing Portal (PPF).
- Tax traceability: shared and reliable statuses, the basis for pre-filled VAT returns.
The DGFiP list specifies that provisional registration is the first step; technical validation (PPF/PA interoperability) completes the final certification—a milestone scheduled by the administration.
September 2026
September 2027
Issuance + e-reporting: SMEs, VSEs, and micro-enterprises
On September 1, 2027, the obligation to issue e-invoices extends to all SMEs, VSEs, and micro-enterprises. With receipt already in place since 2026, the challenge becomes structured issuance and data transmission (e-reporting when necessary) without operational disruption. With Weproc PA Connect (PA), you centralize your outgoing invoices, correctly address your clients via the national directory, and track shared statuses to reduce disputes and secure your cash flow. The native integration with Weproc (orders, budgets, matching) allows you to industrialize the Purchase-to-Pay cycle while remaining 100% compliant.

FAQ – E-invoicing
Are you preparing your company for the e-invoicing reform?
Find answers here to the most common questions about receiving, issuing, and processing supplier e-invoices.
What is an electronic invoice under the French reform?
An electronic invoice is not just a PDF. It’s a structured document containing data that can be read by information systems (e.g., Factur-X, UBL, CII), compliant with the EN 16931 standard.
It must be issued, transmitted, and received via a Certified Platform (PA) or the Public Invoicing Portal (PPF).
This structured format guarantees processing automation, data reliability, and traceability of the invoice lifecycle.
When does e-invoicing become mandatory?
The reform will be rolled out progressively starting September 1, 2026:
All companies must be able to receive e-invoices by this date.
Large enterprises and mid-sized businesses (ETI) must also issue their electronic invoices and transmit their data (e-reporting).
SMEs and VSEs will follow on September 1, 2027 for issuance.
This timeline is set by the DGFiP and aims to digitize the entire B2B invoicing flow in France.
What is the difference between the PPF and a Certified Platform (PA)?
The Public Invoicing Portal (PPF) is the state’s platform.
Certified Platforms (PA), like Weproc PA Connect, are private entities authorized to issue, receive, and transmit e-invoices in compliance with the PPF.
They offer extended features: compliance checks, status tracking, matching, approval workflows, and accounting integration, all while ensuring legal compliance and secure exchanges.
What are the main accepted e-invoice formats?
The reform is based on three standardized formats:
Factur-X: A hybrid Franco-German format (PDF + CII XML).
UBL: A European XML format used in many ERPs.
CII: A structured syntax compliant with the EN 16931 semantic model.
These formats enable automatic reading by management software and guarantee interoperability between companies, ERPs, and certified platforms.
