E-invoicing: ready for September 2026?

September 2026. That date is etched into the diary of every French company, whatever its size. Why? Because by then, e-invoicing will become mandatory for all economic players in the country. An unavoidable digital shift that upends habits, shakes up admin processes and raises quite a few questions. Are you the head of a TPE (a French very small business), an HR director, a CMO or a CTO? Then this article is for you. Let’s take stock together, without unnecessary jargon, of what really lies ahead.

Before/After E-Invoicing

Mandatory e-invoicing: what exactly are we talking about?

E-invoicing is much more than a simple PDF sent by email. It’s a 100% paperless, structured and secure process that lets companies exchange invoices via certified platforms. In practice, out go paper invoices and Word files converted to PDF; in come documents in a standardised format (such as Factur-X or UBL), sent through official channels and compliant with legal requirements.

The e-invoicing obligation is part of a broader digital transition driven by the French State. The goal? Simplify exchanges between companies (the famous B2B), fight VAT fraud, speed up payment times and, incidentally, reduce the carbon footprint linked to paper. Ambitious, isn’t it?

But be careful: this isn’t just an option or a recommendation. From September 2026, all companies subject to VAT will have to be able to receive electronic invoices. For issuing invoices, a phased timetable has been put in place according to company size. Large companies and ETI (mid-sized companies) will lead the way, followed by very small businesses and SMEs (TPE and PME). Suffice it to say it’s time to get serious about it.

Why this e-invoicing reform?

You may be wondering why the State is imposing this change. There are several reasons behind this ambitious reform.

First, the fight against tax fraud. Every year, billions of euros slip under the tax authorities’ radar because of fictitious invoices, VAT carousels or dubious transactions. With a centralised, traceable system, these practices become much harder to carry out.

Next, administrative simplification. For companies, managing mountains of paper, archiving, filing, finding a 2019 invoice in the middle of a tax audit… is time-consuming and a source of errors. Going paperless promises to streamline all that: automatic storage, instant search, real-time tracking.

Another significant benefit: faster payments. By going through digital platforms, invoice processing times are reduced. Less paper stuck on a desk, fewer things forgotten, fewer delays. For the cash flow of very small businesses and SMEs, that’s a real plus.

Finally, e-invoice compliance aligns with European standards. France isn’t the only country going down this road: Italy, Spain and Poland have already made the move. European harmonisation makes cross-border trade easier and strengthens French companies’ competitiveness internationally.

How does business e-invoicing actually work?

Let’s get down to business. How does this whole e-invoicing thing work in real life?

Everything relies on dematerialisation platforms certified by the State. These platforms act as trusted intermediaries: they receive your invoices, check them, send them on to your clients and store them securely for the legal archiving period. The public portal Chorus Pro, already used to invoice the State and local authorities, will be at the heart of the system. But it won’t be alone: approved private platforms will also be able to offer their services.

The typical process looks like this: you create your invoice in your management software (ERP, CRM, accounting tool, whatever), which generates a file in a structured format, then sends it automatically to the platform of your choice. The platform runs checks (format compliance, data consistency, presence of mandatory information), then sends the invoice to your client via their own platform. Everything is tracked, time-stamped and secure. No room for improvisation.

It’s the same on the receiving side. Your suppliers will send you their invoices through these same channels. You’ll receive them in your system, ready to be integrated into your accounts. No more invoices lost in spam or forgotten at the back of a drawer.

Key steps to get ready before September 2026

Right, now that you’ve understood the principle, let’s talk strategy. How do you make sure you’re ready on D-day without stress or last-minute panic?

Audit your current processes

Step one: step back from the day-to-day and analyse your current practices. How do you manage your invoices today? Excel? Ageing accounting software? PDFs sent by email? A mix of paper and digital? Identify the weak points, the bottlenecks, the sources of error. This inventory will help you gauge the scale of the job.

Choose the right technology solution

Next, you’ll have to decide: which platform should you use? Is Chorus Pro enough, or should you go through a private provider with more features? Is your current management software compatible with the new e-invoice formats? If not, you’ll either have to upgrade it or replace it. This is the time to compare offers, try demos and consult your IT and finance teams.

Train your teams

It’s not always front of mind, but the success of this transition also depends on people. Your team members need to understand the whys and wherefores, master the new tools and adopt the right reflexes. Plan training sessions, practical guides and tailored support. Don’t underestimate the learning curve.

Secure your data

Going paperless is great… as long as your data stays protected. Check that your solutions comply with GDPR, that your servers (or your provider’s) are secure, and that backups are automatic and regular. A data leak or a cyberattack could turn your shiny digital transition into a nightmare.

Test and adjust

Finally, don’t dive in head first on 1 September 2026. Start testing your processes several months in advance. Send a few e-invoices in pilot mode, identify bugs, fix, refine. Better to spot a problem in the testing phase than in full production.

E-Invoicing Timeline

E-invoicing and freelancers: what’s the impact?

If you’re a very small business that regularly works with freelancers, this question deserves a closer look. At Digitags.work, we connect companies with freelance talent in tech and digital marketing. And we know many independents have questions about this famous reform.

Good news: freelancers (micro-entrepreneurs, i.e. France’s micro-business status, independent professionals taxed under BNC — non-commercial profits — etc.) won’t all be in the same boat. Those who invoice only private individuals (B2C) are not affected. However, as soon as they invoice companies (B2B), they too will have to switch to e-invoicing.

For you, running a very small business and working with freelancers, this means your external providers will also have to switch to e-invoicing. Factor this into your contractual relationships, check that your regular talent are aware of it, and help them if needed. It’s part of a healthy, lasting collaboration.

In fact, if you’re looking for tech or marketing freelancers who are already aware of digital issues and able to adapt quickly to new standards, don’t hesitate to explore the profiles on Digitags.work. Because a good freelancer is also someone who stays up to date.

Platforms and tools to know

Now let’s talk concretely about the solutions available.

Chorus Pro is the go-to public platform. Free of charge, it’s already used by millions of companies to invoice the State. It will evolve to become one of the pillars of the B2B system. Simple and secure, but sometimes considered a little austere in terms of interface and advanced features.

Alongside it, there are dozens of approved private dematerialisation platforms: Sage, Cegid, Pennylane, Axonaut, Sellsy and many more. They often offer additional features (dashboards, automatic reminders, deep integration with your ERP, artificial intelligence to detect anomalies…). Some specialise in very small businesses, others are geared more towards SMEs or large groups. Take the time to compare.

Already using management or accounting software? Check whether it offers an update that complies with the regulations. Many vendors have already seen this coming and offer dedicated business e-invoicing modules.

To choose, ask yourself the right questions: how many invoices a month? What level of automation do you want? What budget? Do you need support, or are you more self-sufficient? The answers will naturally point you towards one solution or another.

Useful resources to go further

To dig deeper into the subject and stay informed of the latest developments, several official sources are essential.

The website of the Direction générale des Finances publiques (DGFiP, the French public finances directorate) regularly publishes guides, FAQs and tutorials on e-invoicing. It’s the reference for understanding the legal obligations, the precise deadlines and the penalties for non-compliance.

The Chorus Pro portal also offers comprehensive documentation, webinars and technical support to help you get to grips with the public platform.

Finally, don’t hesitate to consult the professional associations in your sector, talk to your peers, and attend conferences or trade shows dedicated to digital transformation. Sharing experience is often the best accelerator for learning.

FAQ: your questions about e-invoicing

Is e-invoicing really mandatory for all companies?

Yes: from September 2026, all companies subject to VAT in France will have to be able to receive electronic invoices. Issuing will follow a phased timetable according to company size, but eventually everyone will be affected.

Can I keep using my current accounting software?

It depends. If your software can generate invoices in a structured format (Factur-X, UBL…) and connect to a dematerialisation platform, then yes. If not, you’ll either have to update it or replace it. Check with your software vendor to confirm compatibility.

What are the penalties for non-compliance?

Companies that don’t meet the e-invoicing obligation face fines. The precise amounts and terms will be set by the tax authorities, but it’s better to plan ahead to avoid any risk of penalties.

Are micro-entrepreneurs affected?

Yes, as soon as they invoice companies (B2B). However, those who work only with private individuals (B2C) remain exempt for the time being. But if you’re a freelancer with business clients, get ready.

How much does it cost to set up e-invoicing?

It all depends on the solution chosen. Chorus Pro is free, but offers limited features. Private platforms offer monthly or annual subscriptions, with prices that vary according to invoice volume and the services included. Expect anywhere from a few tens to several hundred euros a month for a very small business, sometimes more for larger organisations.

Conclusion: don’t get left on the platform

September 2026 isn’t that far away. And in the business world, two years go by quickly. Very quickly. E-invoicing isn’t just another administrative whim; it’s a real upheaval that will affect all of your financial and commercial processes.

So yes, it takes time, energy, perhaps a bit of investment. But it’s also a tremendous opportunity to modernise your company, become more efficient, secure your data and align with European standards. Companies that anticipate this shift will gain a competitive edge. Those that wait… risk being left behind.

Are you the head of a very small business, a CMO, a CTO, an HR director? Now is the time to act. Audit your processes, choose your tools, train your teams, test, adjust. And if you need reinforcements — developers, digital consultants, digital transformation experts — think of the freelance talent you can find on platforms like Digitags.work. Because sometimes, the best way to move forward is to surround yourself with the right people.

E-invoicing isn’t the future. It’s already the present. So, are you ready for September 2026?
