Common e-Invoicing Mistakes in France & How to Avoid Them

E-invoicing, as a concept, is similar in every country where it’s been implemented, even if the technical compliance rules vary from place to place. Usually, when e-invoicing becomes mandatory, businesses in the initial rollout phase tend to make a few common mistakes.

From September 1, 2026, e-invoicing will be mandatory for all VAT-registered businesses in France. This means companies must issue, receive, and report their invoices only in approved digital formats, using certified platforms.

B2B e-invoicing is new for businesses in France; it’s expected that many will face challenges and make some mistakes as they adapt to the new rules. After studying the experiences of over 20 countries where e-invoicing has already gone live, we’ve identified 12 of the most common mistakes businesses make when trying to comply with e-invoicing requirements.

What is E-Invoicing?

E-invoicing, or electronic invoicing, is the process of creating, sending, receiving, and storing invoices in a structured digital format instead of traditional paper or simple PDF files. In France (and many other countries), e-invoicing is now a legal requirement for businesses, enabling invoice data to be transmitted automatically through certified platforms. 

e-invoices must be generated and exchanged in approved electronic formats (like UBL, CII, or Factur-X), which are machine-readable and facilitate automated processing. This not only streamlines business processes and improves accuracy, but also allows tax authorities to monitor transactions in structured data in real time, reducing fraud and making tax reporting easier for everyone involved.

Key Compliance Requirements for France’s E-Invoicing Mandate

France’s e-invoicing reform brings major changes for all VAT-registered businesses, aiming to make invoice exchange and tax reporting faster, more secure, and transparent. Here are the essential compliance requirements every business should know:

1. Every business established in France and subject to French VAT must follow the e-invoicing rules for B2B transactions.
2. e-Invoices must be in approved electronic formats: Factur-X, UBL, or CII, not just PDF or paper.
3. e-Invoices must be sent and received via government-approved Partner Dematerialization Platforms (PDPs), not by email.
4. All companies must be able to receive e-invoices by September 1, 2026. Large and mid-sized companies must also issue e-invoices from this date; SMEs and micro-businesses follow in 2027.
5. Each e-invoice must include required fields like SIREN/SIRET numbers, VAT details, and payment terms.
6. Invoice data is automatically and instantly sent to French tax authorities (DGFiP) for VAT control.
7. B2C sales and cross-border transactions are not e-invoiced, but must be reported electronically (e-reporting).
8. All electronic invoices must be securely archived for at least 10 years.

12 Common Mistakes While E-Invoicing in France

Here are the 12common mistakes to avoid during this transition and strategies to prevent them.

1. Waiting Until the Last Minute to Prepare

One of the costliest errors companies make is delaying e-invoicing adoption. Some may assume that e-invoicing is a simple task that can be addressed just before the deadline. However, implementing e-invoicing involves adapting tax, IT, and business processes. With limited working days available between late 2024 and the September 2026 deadline, businesses need ample time to update their invoicing software, integrate with e-invoicing platforms, and refine VAT reporting processes.

How to Avoid This Mistake: Treat e-invoicing compliance as a strategic project, not just a checklist item. Start now by forming a cross-functional team to plan for software updates, staff training, and platform integration. Early action will prevent rushed implementations and costly mistakes.

2. Rushing to Choose the Wrong E-Invoicing Platform

Some businesses rush to select an e-invoicing platform without proper evaluation, merely to meet compliance deadlines. France allows the use of accredited private platforms (PDPs) or the public platform. However, platforms may not be fully certified until 2025 or 2026, and selecting a platform hastily can result in poor functionality or non-compliance.

How to Avoid This Mistake: Take the time to assess your business needs before selecting a PDP. Consider factors like invoice volume, software integration, industry-specific requirements, and international capabilities. Conduct due diligence and engage with IT and accounting advisors to choose a solution that aligns with your needs.

3. Assuming "It Won’t Affect Me"

Small businesses, or those primarily dealing with B2C transactions, might think the mandate doesn’t apply to them. However, the e-invoicing reform affects all VAT-registered businesses. Even if you don’t issue e-invoices, you must still be able to receive them. Additionally, businesses must comply with e-reporting obligations, especially regarding B2C sales data.

How to Avoid This Mistake: Understand the scope of the mandate and determine your business's obligations. Ensure you can receive e-invoices and stay up-to-date with reporting requirements. Even if your business isn’t required to issue invoices electronically, compliance is necessary for receiving invoices and reporting B2C transactions.

4. Limiting Your Solution to France Only

If your business operates internationally, adopting a platform that only works within France may create future challenges. Many European countries are moving toward electronic invoicing, and using separate systems in different markets increases complexity and costs.

How to Avoid This Mistake: Choose a solution with multi-country capabilities or Peppol integration. By selecting an international provider, you can streamline invoicing operations across multiple jurisdictions, avoiding the need for separate systems in each country.

5. Neglecting Data Quality (Customer/Supplier Master Data)

A significant error in e-invoicing compliance is neglecting data quality. E-invoicing relies on accurate identification of invoice parties (e.g., tax IDs, VAT numbers). If customer or supplier data is outdated or incorrect, invoices may fail to be processed or transmitted.

How to Avoid This Mistake: Conduct a thorough audit of your customer and supplier records to ensure accurate and up-to-date information, such as valid tax IDs and addresses. Clean up duplicates and outdated entries to avoid disruptions in invoice routing.

6. Overlooking Internal Process Changes

E-invoicing affects the entire invoice processing lifecycle, not just the sending and receiving of invoices. Businesses often focus solely on external compliance and neglect necessary changes to internal processes, such as invoice approval, matching, and handling rejections.

How to Avoid This Mistake: Use the e-invoicing transition as an opportunity to streamline your internal workflows. Ensure that all invoice processing steps, from creation to payment, are integrated into the e-invoicing platform. Automating these processes will reduce errors and increase efficiency.

7. Underestimating Change Management and Training

Implementing e-invoicing is not just a technological change but also a cultural one. Businesses often fail to adequately prepare employees for the new system, leading to resistance and errors.

How to Avoid This Mistake: Plan for change management by involving all stakeholders in the transition process. Provide training well before the system goes live, including user guides and hands-on sessions. Address any concerns and highlight the benefits of the new system.

8. Believing E-Invoicing Will Be Completely Free or Handled by the Government Portal

Some businesses assume that the French government’s public invoicing portal (PPF) will be a free, one-stop solution. However, the PPF has limitations and won’t provide all the features available in commercial solutions.

How to Avoid This Mistake: Plan to use a certified private platform (PDP) for full e-invoicing capabilities. While the PPF can handle basic invoicing, you may need additional functionality like integration with your accounting software. Ensure you understand the costs involved in using any platform and evaluate the total value, not just the sticker price.

9. Overcomplicating with Too Many Platforms or Tools

Some businesses consider using multiple e-invoicing platforms, for example, one for sending invoices and another for receiving them. This can increase complexity and reduce efficiency, especially for smaller businesses.

How to Avoid This Mistake: Opt for a single platform to handle both sending and receiving e-invoices. This simplifies training, centralizes records, and ensures smoother invoice processing. Only consider multiple platforms if there’s a clear benefit, such as specialized requirements for certain subsidiaries or industries.

10. Focusing Only on the First Phase (Receiving) and Not Planning for Later Obligations

The e-invoicing mandate is phased: all businesses must be able to receive e-invoices by 2026, but the requirement to issue them is staggered. Small businesses must be prepared to issue e-invoices by 2027 and failing to plan for this in advance can lead to rushed implementations.

How to Avoid This Mistake: Plan for both receiving and issuing e-invoices from the start. Even if your business only needs to receive invoices in 2026, consider how you’ll issue them in 2027. This holistic approach will help you avoid needing to transition to a new system later.

11. Forgetting Archiving and Integrity Requirements

In addition to transmitting invoices, businesses must comply with archiving and integrity requirements. French law mandates that electronic invoices must be securely stored and retrievable for at least 10 years.

How to Avoid This Mistake: Ensure that your e-invoicing solution includes secure archiving or integrates with a compliant archiving system. Verify that invoices are stored with all required metadata and that they remain accessible for audits.

12. Not Capturing All Mandatory Fields and Details on Invoices

The e-invoicing mandate introduces new mandatory fields on invoices, such as the SIREN number for both the issuer and the recipient. Failing to capture all required details can result in non-compliance and rejected invoices.

How to Avoid This Mistake: Update your invoice templates and billing systems to capture all necessary data, including the correct SIREN numbers, VAT breakdown, and invoice type indicators. Testing invoices before going live can help ensure that all fields are correctly included.

Companies need to start early, select a reliable platform with both domestic and international capabilities, and clean their master data to ensure smooth invoice routing. Equally important is rethinking internal workflows so that sending, receiving, and archiving are integrated, secure, and efficient.

Training and change management should bring all teams on board, while invoice templates must be updated to capture the new mandatory details. By consolidating onto a single, future-proof solution and budgeting realistically, businesses can move beyond basic compliance to unlock faster payments, reduced errors, and streamlined financial operations.
