E-Invoicing Compliance in France, Handled for 2026

France's E-Invoicing Mandate Is Coming: Who Has to Comply, and When

E-invoicing is becoming mandatory in France on September 1, 2026. From that date, every business, whatever its size, must be able to receive e-invoices. The obligation to issue in electronic format, on the other hand, starts in September 2026 for large companies and mid-sized companies, then reaches SMBs, very small businesses, and micro-enterprises a year later, on September 1, 2027.

I'm Amalia Bercot, co-founder and CEO of Sanso. Before starting Sanso, I was part of the founding team at Brevo, and I've run companies day to day. So I know exactly what a new administrative obligation means for a small business owner: one more thing to digest, one more tool to choose, one more process to set up, all while you already have a business to run.

Be warned, the reform isn't just about "emailing a PDF." Starting in September 2026, invoices will have to go through a platform accredited by the tax authorities, in a structured, machine-readable format (such as Factur-X). On top of that comes the obligation to transmit certain transaction data to the tax authorities, known as e-reporting. For a small business, that means rethinking how you invoice, how you receive supplier invoices, and how you track payments.

How Sanso Handles Your E-Invoicing

Sanso handles the work of e-invoicing for you. And no, we're not yet another piece of software to install and then tame: Sanso is an AI-powered financial management service. The AI does the bulk of the work (invoice capture, reading, validation, issuing, follow-ups, reconciliation), while our team supervises and steps in on the sensitive cases.

In practice, Sanso plugs into the tools you already use: your accounting platform (Pennylane as the primary integration, but also Tiime, Axonaut, or Xero), your bank (Qonto, Revolut Business), your Google Workspace. On the regulatory side, Sanso routes your invoices through the compliant platforms you already have, like Pennylane. You keep your tools, your data stays with you, and everything stays visible in your usual environment.

The result: no need to become an e-invoicing expert. Sanso's AI handles the day-to-day mechanics and pushes your invoices through the compliant platform you already use, which takes care of the right format and the transmission. Meanwhile, you keep running your business. 2026-2027 compliance ends up running in the background instead of piling up on your desk.

What Sanso's AI Handles

Receiving Supplier Invoices

Sanso's AI captures your supplier invoices across every channel, without you having to chase them. It connects to your inbox, reads every message and attachment, tells a real invoice apart from a quote or a greeting card, weeds out duplicates, and routes the right document to your accounting platform. And for the invoices that only live on supplier portals (utilities, SaaS, telecom operators), an AI agent goes and retrieves them directly. The day the e-invoicing mandate takes effect, your incoming invoices are already processed and filed where they belong.

Issuing and Sending Your Client Invoices

Sanso's AI can recognize that a project is finished and therefore needs to be invoiced, generates the invoice with the right amount and the right entity, then sends it. It also reviews your quotes to catch what slipped through the cracks: at small businesses, nearly 5% of invoices are never issued at all, simply because no one thought of them. Sanso makes these oversights disappear, and your invoices go out in the format and through the channel the reform expects.

Validation and Compliance Checks

Before any payment goes out, Sanso's AI scrutinizes every supplier invoice: no duplicates, consistency with the quote or purchase order, amounts and VAT checked. A compliant e-invoice rests on accurate, complete data, nothing more, nothing less. That's exactly what this step secures, with no manual data entry on your side.

Reading and Extracting Data (AI-Powered OCR)

Sanso's AI reads and understands your financial documents: not just standard invoices, but also rent statements, capital calls, and construction progress statements. It extracts the key information (amount, VAT, supplier, date, purchase order number) and ties each document to its context to clear up any gray areas. In the end, you get structured data, ready to feed your accounting and the formats e-invoicing requires.

Bank Reconciliation and Payment Tracking

For every bank transaction, Sanso's AI finds the matching purchase or sales invoice in real time. At any moment, you know who has paid, what's pending, what's dragging on, and your VAT data holds up. As for collections on unpaid invoices, they're handled end to end, through personalized, multichannel follow-up, a far cry from a simple automated reminder system.

Who This Is For

• Owners of small businesses (5 to 50 employees) who want to be compliant with the e-invoicing mandate without giving up their evenings to it.
• Founders and business owners who still handle finance admin themselves and honestly don't have time to decode the reform.
• CFOs and admin managers at growing small businesses, keen to make invoice issuing, receipt, and archiving reliable.
• Law firms, consulting agencies, startups, tradespeople, and construction companies wrestling with complicated invoices (multi-stage billing, tricky collections, project-based cost accounting).
• Online retailers and marketplace sellers buried under invoice volumes and endless reconciliations.

How It Works

1. We talk on a call. We look together at your situation, your tools, and where you really stand on e-invoicing.
2. We plug into your tools. Sanso connects to your accounting, your bank, and your Google Workspace. Onboarding takes a few days, without disrupting your business.
3. The AI takes over the day-to-day. Supplier invoice capture, client invoice issuing, validation, reconciliation: the AI does the work while our team supervises.
4. You see everything in your tools. Invoices in Pennylane, payments in your bank. Nothing is hidden, and we stay reachable by email or WhatsApp.
5. You stay compliant, continuously. As the 2026 and 2027 deadlines approach, your invoices are already in the right format and go through the right channel.

Results You Can Expect

With Sanso, e-invoicing compliance stops being a project and becomes a given. No more chasing supplier invoices, no more forgetting to issue a client invoice. Bank reconciliation that used to stretch over days now happens continuously: one of our clients went from two days of reconciliation to a few minutes, with about 96% automatic reconciliation. Another cut their four weekly hours of chasing invoices down to a few minutes.

And above all, you get back time and a little peace of mind. Plans start at $300/month, less than a part-time minimum-wage hire, with no commitment. You stop whenever you want.
