Electronic Invoicing in France: 9 Points to Check Before Sending Your Invoices

Creating an electronic invoice does not simply mean turning a Word or Excel invoice into a PDF. With the French e-invoicing reform, businesses will have to create, send and receive invoices in structured formats through an approved platform.

From 1 September 2026, electronic invoicing will be gradually rolled out between VAT-registered businesses in France. Large companies and mid-sized companies will be the first required to issue electronic invoices, while SMEs and very small businesses will have until 1 September 2027 to issue their electronic invoices. However, all businesses must be able to receive electronic invoices from the start of the system.

To avoid rejections, payment delays and compliance errors, here are the 9 most common mistakes to avoid when preparing your electronic invoicing process.

Why Is Electronic Invoicing Becoming a Key Topic in France?

The French reform significantly changes the way companies create and send invoices. A valid electronic invoice must contain structured data that can be automatically read by IT systems and must be transmitted through an approved platform.

The expected formats include UBL, CII and Factur-X. A simple PDF sent by email does not qualify as a compliant electronic invoice under the reform.

The reform is not only about sending invoices. It also includes the transmission of certain data to the tax administration, including invoicing, transaction and payment data depending on the case. These exchanges are handled through approved platforms.

Mistake 1: Believing That a PDF Sent by Email Is Enough

This is probably the most common mistake.

Today, many businesses create an invoice in Word, Excel or invoicing software, then send it as a PDF by email. This process may seem “paperless”, but it does not meet the requirements of the reform.

A compliant electronic invoice must contain structured data, for example in a format such as UBL, CII or Factur-X. A standard PDF, even if professionally designed, remains a document mainly readable by humans, not by control and automated processing systems.

Mistake 2: Waiting Too Long Before Choosing an Approved Platform

To issue, receive and transmit the required data to the tax administration, businesses will have to use an approved platform. The French tax administration states that an approved platform is authorized to manage the essential functions of the reform: issuing, transmission, reception, e-reporting and status exchange.

Waiting until the last minute can create several problems:

• not enough time to test the solution;
• difficulties integrating with the ERP or accounting software;
• errors in customer data;
• delays in issuing or receiving the first electronic invoices.

Mistake 3: Confusing Electronic Invoicing and E-Reporting

Electronic invoicing applies to invoices exchanged between French businesses subject to VAT. But some transactions do not always follow the same flow: sales to individuals, international transactions or certain payment data may fall under e-reporting.

The tax administration indicates that approved platforms also contribute to the transmission of transaction and payment data to the administration.

Failing to distinguish between these two obligations can lead to processing errors.

Key Takeaway

E-invoicing: issuing, receiving and transmitting electronic invoices between businesses concerned by the reform.

E-reporting: transmitting certain data to the administration for transactions that do not directly fall under the e-invoicing flow.

Docnova helps centralize electronic invoicing flows and reporting needs to avoid managing several separate processes.

Mistake 4: Forgetting the Mandatory Information on the Invoice

Even with a platform or software, an invoice remains a tax document. Certain information must be correctly included: seller identity, customer identity, invoice number, date, amounts, VAT, payment terms, legal references where applicable, and more.

With the reform, data accuracy becomes even more important because platforms perform checks before transmission. An incomplete or inconsistent invoice may be rejected, which can delay delivery to the customer and therefore payment.

Mistake 5: Not Checking the Customer’s VAT Status

Not all invoices necessarily follow the same processing flow. Your customer’s status is essential: VAT-registered business, individual, association, foreign customer, public administration, and so on.

Mandatory electronic invoicing mainly targets transactions between French entities subject to VAT.

If you send an invoice through the wrong flow, you may face rejection or incorrect processing of the transaction.

Example

An invoice sent to a French VAT-registered company will not be processed in the same way as a sale to an individual. The required data, transmission channel and reporting obligations may vary.

Mistake 6: Neglecting the Quality of Customer Data

Electronic invoicing relies on accurate information: SIREN, SIRET, VAT number, billing address, delivery address, company name, routing identifiers, and more.

Incomplete or outdated customer data can cause:

• invoice rejection;
• routing errors;
• payment delays;
• incorrect accounting allocation;
• time-consuming manual corrections.

The SIREN and SIRET identify a company and its establishments, so this information is important when preparing electronic flows.

Mistake 7: Poorly Managing VAT, Invoice Lines and Rounding

An electronic invoice is not just a technical file. The amounts must be consistent: unit price, quantity, discount, VAT rate, total excluding VAT, total VAT and total including VAT.

A rounding difference or inconsistency between line items and totals can create a rejection or anomaly. The AFNOR XP Z12-012 standard provides useful clarification on the structuring and processing of electronic invoice data.

Good Practice

Check that your tool correctly calculates:

• line-by-line amounts;
• rounding;
• different VAT rates;
• credit notes;
• advance payments;
• discounts.

Mistake 8: Forgetting Advance Invoices and Special Cases

Some businesses manage advance payments, credit notes, partial payments, recurring services or complex multi-line invoices. These cases must also be processed correctly in an electronic invoicing environment.

An advance invoice or credit note should not be improvised in a simple PDF. The data must be understandable by systems and correctly linked to the relevant transaction.

Docnova supports businesses in managing different types of documents: invoices, credit notes, incoming flows, outgoing flows and data related to the invoice lifecycle.

Mistake 9: Thinking the Reform Only Concerns Large Companies

Many very small businesses, SMEs, freelancers and micro-entrepreneurs think electronic invoicing is only a topic for large groups. This is a mistake.

Even if the issuance calendar is progressive, businesses must prepare to receive electronic invoices and adapt their processes. The administration reminds businesses that even some companies that do not charge VAT may be concerned by the reception of electronic invoices.

What This Changes in Practice

Even a small business will need to ask the right questions:

• How will I receive supplier invoices?
• Which platform will I use?
• Is my current software compatible?
• Is my customer data ready?
• How will I track invoice statuses?
• How can I avoid compliance errors?
