Free invoicing software : which tool to choose to be compliant with electronic invoicing ?

In short — Electronic invoicing becomes mandatory in France from September 2026 for receiving and September 2027 for issuing. Good news: free and compliant solutions exist for all types of entrepreneurs. The challenge is choosing the tool suited to your situation without falling into freemium traps. This guide deciphers the best options, the regulatory obligations, and proposes a concrete method to decide.

Key points to remember : 🎯 Two essential dates: mandatory receipt in September 2026, progressive issuance until September 2027 • 📋 Three compliant formats: Factur-X (ideal for micro/SMEs), UBL and CII • ✅ Verify that the tool holds the Plateforme Agréée (PA) status registered by the DGFiP • 💰 Several 100% free solutions with no invoice limits • ⚠️ Beware of freemium traps: paid receipt, lack of PA, limited features • 🔍 Choose according to your profile: micro-entrepreneur, freelancer, small business or growing SME.

🔐 Electronic invoicing: a legal framework that is becoming clearer

For several years, invoice dematerialization has been progressing slowly in France. But in 2026, the movement truly accelerates. The tax administration has set a strict timetable for all VAT-liable economic actors to switch to mandatory electronic invoicing in France.

This transformation is not a mere administrative detail. It addresses concrete objectives: fight tax fraud, simplify B2B exchanges, and create full traceability of commercial transactions. For companies, it means gradually abandoning PDFs sent by email to adopt structured formats transmitted via Plateformes Agréées (PA) officially recognized by the DGFiP.

Understanding this legal framework is the first step before choosing your digital invoicing software. Because any free or paid solution must meet these constraints to be compliant.

📅 Reform schedule: key dates and progressive obligations

The transition to electronic invoicing spans two years, with well-defined steps to give companies time to adapt.

🗓️ September 1, 2026: This is the moment when all companies, without exception, must be able to receive electronic invoices. At the same time, large companies (LE) and mid-sized companies (ETI) must begin issuing their invoices in electronic format. Others are granted additional time.

🗓️ September 1, 2027: SMEs, very small enterprises and micro-enterprises finally switch to mandatory issuance. This is the final step before the entire French economic fabric operates in dematerialized form.

This strategic phasing allows everyone to prepare without haste. But beware: waiting until the last week before the deadline risks not finding technical support or compliant software. It is better to anticipate now.

📌 The three electronic invoice formats to know

The reform accepts three formats compliant with the European standard EN 16931. Each responds to different needs depending on your type of activity and commercial exchanges.

💼 Factur-X: the hybrid format for the majority

Factur-X combines a human-readable PDF with structured XML data in the background. It's the ideal choice for TPEs, SMEs and craftsmen who work primarily in France. It offers the best of both worlds: your clients can view a familiar document (a PDF) while allowing recipients' accounting software to automatically process the data.

This hybridity makes Factur-X particularly practical for small entities that do not necessarily master pure XML. Plateformes Agréées handle automatic conversion if your client uses another format.

🌍 UBL: international and interoperability

UBL (Universal Business Language) is a pure XML format without a PDF representation. It is internationally recognized and used notably on the PEPPOL network for cross-border exchanges. If your company exports or regularly collaborates with European partners, UBL becomes relevant.

This format requires a bit more technical know-how, but it guarantees maximum interoperability between different information systems.

📊 CII: the standard for complex operations

CII (Cross Industry Invoice) is the ISO/UN standard for complex commercial transactions. It is particularly suited to large companies, the construction sector, multi-channel distribution, or those with very rich data exchange needs (tax nuances, withholdings, detailed breakdowns, etc.).

For the majority of entrepreneurs, CII remains an advanced choice. But for those who need it, it's the most complete solution.

🆓 The 8 best free electronic invoicing tools in 2026

Several 100% free solutions allow you to anticipate the reform without a software budget. But beware: not all are equal. Here are the eight most reliable tools, analyzed according to their Plateforme Agréée status, their real free scope, and their included features.

✨ Facture.net: genuinely unlimited free

Facture.net is one of the rare tools to offer a 100% free plan with no limits: unlimited number of invoices, unlimited number of clients, and the publisher commits to keeping it free even after September 2026. The tool integrates its own Plateforme Agréée to transmit your invoices in compliance.

Strengths: total free without hidden freemium, integrated CRM, multi-format exports (Factur-X, UBL, CII), simple and intuitive interface, compliance guaranteed with the anti-VAT fraud law. Limitations: very advanced features (advanced bank reconciliation, conditional reminders) are less developed than premium competitors.

For micro-entrepreneurs and TPEs who simply want to issue and receive invoices without complications, Facture.net remains an excellent starting choice.

⚙️ Tiime: the PA registered for freelancers

Tiime is a French fintech created in 2015 and registered as a Plateforme Agréée under number 0037 by the DGFiP. Its free offer covers unlimited creation of quotes and invoices, including recurring invoices — an essential function for freelancers and consultants who bill the same clients regularly.

The interface is particularly smooth and designed for independents. The official PA status eliminates any ambiguity about compliance. However, companies under the VAT exemption regime must switch to the paid plan (from €14.99 excl. VAT/month), and automated reminders are reserved for higher plans.

🏗️ Henrri: the professional outsider from Groupe Rivalis

Henrri is developed by Groupe Rivalis, a software publisher since 1994. This affiliation brings a guarantee of longevity and reliability that young startups cannot always offer. The tool promises a professional invoicing software, free, without restriction on issuing and receiving.

Strengths: free without limit, compatible with all accounting tools from January 2026, team of 15 dedicated developers, accessible human support. The interface is less trendy than that of neobanks, but it works efficiently for traditional trades.

📈 Pennylane: the most complete for the ambitious

Pennylane is a complete accounting and invoicing solution used by nearly 600,000 companies. Registered as a Plateforme Agréée, it offers receipt and issuance of electronic invoices in its free plan. It's one of the rare ones to natively support the three formats (Factur-X, UBL, CII) and to benefit from high-level certifications (ISO 27001, SecNumCloud hosting).

If you plan to grow and are looking for an evolutive solution without future migration, Pennylane is worth testing. The free version may show its limits for very advanced needs, but it robustly covers standard uses.

💳 Abby: electronic signature included

Abby offers a free basic plan with issuance and receipt of invoices. Its plus: electronic signature of documents is natively included, useful for independents who ask their clients to validate quotes before engagement.

Registered as a PA, Abby specifically targets micro-entrepreneurs and independents looking for a simple and reassuring all-in-one solution.

🏦 Qonto: the neobank + invoicing

You may already know Qonto for its professional bank account services. This French platform, partner of Crédit Mutuel Arkéa, also offers an integrated electronic invoicing tool registered as a PA.

With Qonto, you issue and receive an unlimited number of compliant invoices for free. Integration with your business account and your accounting speeds up your pre-accounting. If you subscribe to the neobank (€9 excl. VAT/month), you benefit from the account + invoicing combo. But invoicing alone can be tested for free.

✍️ Shine Facture: for independents with a pro account

Shine is the invoicing solution integrated into the neobank Shine. It is included when opening a professional account and offers creation of quotes and invoices, although Shine is not yet officially registered as a PA (status: future PA in progress). For those already using Shine, it's a practical option.

🔗 Flowie: for integrators

Flowie is registered as a PA and targets startups and TPEs that need multiple integrations. Its free offer covers up to 100 invoices/month and supports multi-formats, making it flexible for companies with specific data exchange needs.

⚠️ The five traps of “free” to absolutely avoid

The word “free” in electronic invoicing needs nuance. Here are the five most common traps to know so you don't end up facing hidden costs.

💰 Trap #1: paid receipt

Some tools offer free issuance but charge for receiving supplier invoices. Yet, from September 2026, all companies must be able to receive electronic invoices. If you have to pay for this function, the real cost of your “free” solution quickly rises. Always check that reception is included in the free plan before committing.

🔒 Trap #2: absence of PA status

A billing software not registered as a PA must necessarily go through a third-party Plateforme Agréée to transmit your invoices. This can lead to additional fees and unforeseen intermediaries. Always check on impots.gouv.fr that the solution is itself a PA or directly connected to a clearly identified PA.

📊 Trap #3: freemium that costs a lot

Free versions often limit essential features: automated reminders, bank reconciliation, advanced accounting exports, multi-users, custom templates. Calculate the real cost by including paid modules you will need in the next six months. A tool advertised at “€0” but that forces you to move to €50 excl. VAT/month after three months is not really free.

❌ Trap #4: compliance claimed but not effective

Some tools claim “compliant 2026” without being operational or verifiable yet. Before choosing, check the official list of registered Plateformes Agréées published on the tax website that your solution is indeed approved or in advanced registration. Do not trust vague promises.

🚨 Trap #5: sustainability of the business model

A 100% free tool must have a viable business model. Ask yourself: how does the publisher make money? Through premium services? Accounting partnerships? Sale of anonymized data? An opaque model is a risk of a change in pricing policy after the reform. Favor established publishers or those with a solid parent structure (like Henrri with Groupe Rivalis).

🎯 Five key criteria to choose your tool without making a mistake

Do not choose your electronic invoicing software solely on price, since zero-euro options exist. Here are the five criteria that truly make the difference.

✅ Criterion 1: Plateforme Agréée status

The tool must itself be a PA registered by the DGFiP or directly connected to an identified PA. Check this status on the official register. It's non-negotiable to be compliant.

📋 Criterion 2: real free scope

Issuance AND reception included? Unlimited number of invoices? Supported formats (Factur-X at minimum)? Limited number of clients or users? Be precise on these points to assess whether the free offer truly matches your needs.

📈 Criterion 3: scalability

Which paid features will inevitably be necessary in 6 to 12 months? At what cost? Does the tool grow with you or will you have to migrate? A solution that allows you to stay free for a long time but forces you to change everything in case of growth is not a good strategic choice.

🔗 Criterion 4: integrations

Compatibility with your current accounting tool, your bank, your existing CRM? Integrations ease onboarding and eliminate redundant manual entries. It's a real time saver.

📞 Criterion 5: customer support

Accessible human assistance (chat, email, phone)? Comprehensive documentation in French? Active community? In case of a technical problem just before the deadline, you'll want to be able to speak to someone quickly. Do not neglect this criterion.

👤 Which tool for which entrepreneur profile?

🎯 You are a micro-entrepreneur or auto-entrepreneur

Favor Facture.net for a no-constraint, no-surprise solution, or Abby if you want a tool with built-in electronic signature to validate your quotes before invoicing. These two solutions cover your standard needs without requiring a switch to a paid plan. Your low billing volume does not justify a monthly subscription.

💼 You are a freelancer or consultant

Tiime is the natural choice: official PA status, free recurring invoices (essential for long missions), and an integrated accounting ecosystem that facilitates exchanges with your chartered accountant. If you bill the same clients every month, Tiime becomes truly relevant.

🏢 You run a TPE (2 to 10 employees)

Henrri offers the best solidity/freedom ratio thanks to its backing by Groupe Rivalis. If you have advanced accounting needs (bank reconciliation, financial steering), Pennylane is the strategic choice to evolve without changing tools in two years.

🚀 You are a startup or growing SME

Pennylane or Qonto combine electronic invoicing, financial steering and banking services. The free version lets you get started, then you scale up as you grow without painful migration. It's a long-term investment in your management infrastructure.

🔧 Step-by-step guide: switch to electronic invoicing in 5 steps

Step 1: audit your current situation

How many invoices do you issue per month? How many do you receive? Do you currently use Excel, Word, or an existing software? Who are your key contacts (accountant, bank, main clients)? This assessment allows you to measure the complexity of your migration and the features truly necessary.

Step 2: choose your Plateforme Agréée

Select a free electronic invoicing tool from those analyzed in this guide. Verify its PA status on the DGFiP official list. Create your account and configure your legal information: SIRET, APE code, VAT regime. It's an administrative but crucial step.

Step 3: configure your invoice templates

Set up your templates by including the four new mandatory mentions: the category of the operation (sale, service, mixed), the mention regarding the option for VAT on receipts if applicable, the full delivery address (if different from billing), and the client's SIREN number. Test a template to ensure all fields are correctly filled.

Step 4: test under real conditions

Send your first electronic invoices to partner clients or to yourself. Verify that transmission via the PA works, that data is correctly extracted, and that recipients receive the documents. Take advantage of the period before September 2026 to resolve technical issues calmly, without pressure.

Step 5: train your teams and communicate

Inform your clients and suppliers of your switch to electronic invoicing. Train employees involved in invoicing. Appoint an internal referent to handle technical questions during the first months. Transparent communication eliminates confusion and payment delays related to poorly received invoices.

📝 Mandatory mentions on an electronic invoice in 2026

Beyond the classic required mentions (vendor and buyer identity, date, numbering, description of products/services, VAT rate and amount), the reform adds specific requirements. Your invoicing software must automatically handle these mentions to avoid any rejection.

🏷️ Category of operation: mandatory indication if sale of goods, provision of services, or mixed operation. This mention helps the administration classify transactions.

📊 VAT on receipts option: mandatory mention if your company has opted for this particular regime. This concerns notably small entities with irregular receipts.

📍 Delivery address: full address of the delivery location, only if different from the billing address. For services or intangibles, this line can be empty.

🆔 Client's SIREN number: the unique identifier of the professional recipient. This data allows the DGFiP to trace commercial flows precisely.

A good software fills these fields automatically or guides you to complete them. Do not leave this step forgotten.

🌟 Why not wait until the deadline to act?

More than 10 million economic actors are concerned by the reform. Only a few hundred Plateformes Agréées will be available at the end. Waiting until the last moment risks not finding a support slot and undergoing an urgent migration, with all the malfunctions that implies.

Anticipate now by testing a free solution. You will be six months ahead of the majority of French companies, which gives you time to solve technical problems, train your team, and adapt your processes calmly.

It's also an opportunity to optimize your administrative flows beyond mere compliance. A digitalized invoice management lets you accelerate collections, reduce accounting errors, and gain several hours per week that you can devote to your core business.
