e-Invoicing for Small Businesses in France: Requirements, Timeline & Next Steps

France’s e-invoicing reform will change how small businesses create, send, receive, and report invoices. From September 2026, every business must be ready to receive electronic invoices, and large and intermediate-sized enterprises must also start issuing them. Small businesses must begin issuing them from September 2027.

Key Takeaways

• All businesses in France must be able to receive electronic invoices from 1 September 2026.
• Small businesses, micro-enterprises, and SMEs must issue electronic invoices and complete applicable e-reporting from 1 September 2027.
• A normal PDF sent by email will not meet the new rules for covered domestic B2B transactions.
• Businesses must use a government-approved Plateforme Agréée, either directly or through connected accounting or invoicing software.
• Invoice volume does not create an exemption. Even businesses sending only a few invoices must prepare.

What is e-Invoicing for Small Businesses?

Under the French reform, the structured invoice contains machine-readable data such as the supplier's identity, customer SIREN, invoice number, taxable amount, VAT rate, VAT amount, and transaction type. France accepts formats such as UBL, CII, and Factur-X, a hybrid format that combines structured XML data with a human-readable PDF.

Electronic invoicing for small business generally covers domestic B2B transactions between businesses subject to VAT and established in France. B2C and many international transactions are handled through e-reporting, which transmits the relevant sales and payment data to the French tax administration.

Is e Invoicing Mandatory for Small Businesses in France?

Yes. The reform applies to small businesses, SMEs, micro-enterprises, freelancers, self-employed professionals, and many micro-entrepreneurs. It is not limited to companies above a particular turnover or invoice-volume threshold.

Businesses benefiting from the franchise en base de TVA are generally still covered by the reform because they remain persons subject to VAT. The scope of e-invoicing depends on whether an operation is a domestic B2B transaction between two taxable persons established in France to which French invoicing rules apply, under Article 289-0 of the French General Tax Code. Some VAT-exempt operations remain within scope, and an operation that falls outside e-invoicing may still be subject to e-reporting, so businesses should confirm the treatment of each transaction type.

Small businesses must separate the receiving and issuing obligations. They must be able to receive electronic invoices from 1 September 2026, while the issuing obligation begins on 1 September 2027. Businesses should therefore have a Plateforme Agréée in place before the receiving mandate takes effect.

e-Invoicing Timeline for Small Businesses

The e invoicing for small business timeline has two main dates.

1. From 1 September 2026, all businesses must be able to receive electronic invoices. Large and intermediate-sized enterprises must also begin issuing e-invoices and completing e-reporting.
2. From 1 September 2027, micro-enterprises, small businesses, and SMEs must begin issuing electronic invoices and completing the applicable e-reporting of their transaction and payment data.

e-Invoicing Requirements for Small Businesses

Instead of treating this as a software upgrade, think of e invoicing for small business as a compliance exercise. Your business must meet the following e invoicing for small business requirements before the mandate applies.

Use a Plateforme Agréée (PA)

Domestic B2B e-invoices must be issued, received, and transmitted through a government-approved e invoicing Plateforme Agréée (PA). You can either use a PA directly or continue using your existing invoicing or accounting software if it connects to one.

Issue Invoices in an Approved Format

Covered domestic B2B invoices must be issued in an approved structured or hybrid format, such as Factur-X, UBL, or CII. A standard PDF sent by email does not meet the e-invoicing requirement.

Include Mandatory Invoice Data

Along with the existing French invoice requirements, certain information must be available in structured fields. This includes details such as the customer's SIREN, transaction category, delivery address (where applicable), and VAT-related information.

Meet e-Reporting Requirements

Transactions outside the domestic B2B e-invoicing flow, such as B2C and many international transactions, must be reported through e-reporting. Businesses providing services may also need to report payment data where VAT becomes chargeable upon receipt of payment.

Retain Invoice Records

Electronic invoices and related records must remain complete, readable, and accessible throughout the applicable retention period. Businesses remain responsible for meeting French tax and commercial record-retention requirements.

Should Small Businesses Choose PPF or PA (PDP)?

Small businesses should choose a Plateforme Agréée (PA). The earlier PPF versus PDP comparison is no longer relevant because businesses now use a PA to issue, receive, and report invoices. The PPF mainly supports the government's central infrastructure.

Use a PA Directly

A PA portal is usually suitable if your business:

• Issues a low volume of invoices.
• Does not rely heavily on accounting or ERP software.
• Has relatively simple invoicing requirements.

Use Existing Software Connected to a PA

Connecting your current invoicing or accounting software to a PA is usually a better option if your business:

• Issues a higher volume of invoices.
• Handles B2C or international transactions.
• Wants automated invoice exchange and reporting.
• Already uses an ERP or accounting system.

Before choosing a PA, confirm that it appears on the official approved-platform list and supports the formats, integrations, and reporting capabilities your business needs.

How e-Invoicing Works for Small Businesses

Once your business is compliant, the invoicing process follows a structured digital workflow.

• Create the invoice using your invoicing, accounting, ERP software, or your chosen PA.
• Your software or PA converts it into an approved format, such as Factur-X, UBL, or CII.
• Send the invoice to your PA. It checks the required information and sends the invoice to your customer's platform.
• The required invoice data is transmitted to the French tax administration through the reform's infrastructure.
• If the customer rejects the invoice, issue a credit note or corrected invoice through the appropriate process.

For B2C and many international transactions, submit the required transaction or payment data through e-reporting instead of domestic B2B e-invoicing.

Benefits of e-Invoicing for Small Businesses

For small businesses, the biggest advantage is not simply replacing paper invoices. The reform introduces structured invoice exchange and reporting, making invoice processing, VAT compliance, and issue resolution more efficient.

• Invoices move through approved platforms. This makes it easier to check whether an invoice was delivered, rejected, corrected, or received.
• Structured invoice data reduces manual work. It also makes VAT reconciliation easier and helps detect missing SIREN details, incorrect VAT information, or incomplete invoice fields early.
• Standardised invoice and status data create a clear audit trail. They also help businesses investigate invoice disputes and processing delays faster.
