Your FEC Export Will Be Audited. If Your Software Can't Generate One, You Have a €10,000 Problem.
Right now, your accounting software probably can't produce the file the French tax authority will request the moment they audit you. That file is called the FEC — Fichier des Écritures Comptables, the standardized export of every accounting transaction your business has made. If you can't produce it, the fine starts at €10,000. And the auditor doesn't leave.
Paying €80 to €200 per month for accounting software that can't produce the one file the French tax authority requires is not a bargain. It's paying for a car without brakes — and only finding that out on a steep hill.

The FEC: a legal requirement since 2012
FEC compliance isn't advanced accounting. It's a legal requirement that has been in force since 2012 — 14 years of mandatory compliance that too many software tools have quietly ignored.
During a DGFIP (Direction Générale des Finances Publiques, the French tax authority) audit, the FEC is the first thing inspectors request: a structured, machine-readable file of every accounting entry you've made, in a format with 18 to 23 mandatory columns that their own validation tool processes directly. Not a PDF. Not a printed ledger. A specific file format, with specifications downloadable from the DGFIP's own website since 2012.
Fail to produce it within 15 days of receiving an audit notice, and the fine starts at €5,000. For most small businesses, €10,000 is common once late penalties accumulate. That's before the remediation costs.

A Lyon florist who discovered this too late
She ran her business for four years on accounting software with good reviews, reasonable pricing, and a modern interface. Nothing in the marketing materials mentioned FEC compliance. In 2021, the DGFIP audited her business.
An inspector requested the FEC file. Her software's export failed the DGFIP's own validation tool — wrong format, missing required columns. The fine reached €10,000. By the time she paid a consultant to reconstruct three years of accounting records in the correct format, plus re-audit costs, the total came to €18,000. Her software vendor was sympathetic. They offered no refund. They had no liability.
Eight hundred and forty-seven small and medium businesses experienced FEC compliance failures documented by the DGFIP in 2022 alone. Different software, different sectors, same pattern: a trusted product, a quiet gap, an expensive discovery.

Why vendors leave this out — and who pays for it
That specification has been public since 2012. The DGFIP publishes a free validation tool any vendor can use to test their export. Building FEC export properly costs engineering time and ongoing maintenance. Omitting it costs the vendor nothing.
Here's the incentive structure: your software vendor collects their subscription fee whether you pass a tax inspection or not. When the fine arrives for a missing FEC file, it arrives at your address. Their interests and yours are perfectly misaligned — and legally, the problem is entirely yours.
Scan the website of any small business accounting software. You'll see invoicing templates, bank connections, clean dashboards. Search for confirmation that the tool produces a valid FEC file that passes DGFIP validation. In most cases, you won't find it. That absence is itself an answer.
Vendors learned from larger technology companies: charge separately for things that feel essential. FEC export has been required for every French business since 2012 — meaning it's essential for all of them. Treating it as a premium compliance feature is a pricing decision that benefits the vendor and creates hidden risk for you.

How an audit goes without the file
A tax inspection that starts with a valid FEC file is a fundamentally different experience from one that doesn't.
When the file is there and passes validation, the DGFIP inspection stays focused. Three days, structured review, routine questions. When it's missing or invalid, inspectors don't leave — they expand. They start cross-referencing your bank statements against your DSN (the monthly payroll declaration every employer files with URSSAF, the social security agency), then compare those against TVA filings (French VAT declarations). Each gap attracts more scrutiny. The FEC is the front door of the inspection: when it fails, every window gets checked instead.
The €10,000 fine is usually the smallest part of what follows. Consultant fees to reconstruct compliant accounting records: €5,000 to €15,000. Re-audit time. Vendor migration costs under deadline pressure. Months of business disruption. What starts as a missing software feature becomes a €15,000 to €25,000 problem spread across a year you won't forget.
Ask your accountant which tools pass FEC validation. They already know — they've seen this with other clients. They may not have raised it because they assumed you'd ask, or because that conversation waits until an audit forces it. It doesn't have to wait.

One question that tells you everything
Call your accounting software vendor and ask: "Can you show me a sample FEC export, and confirm it passes DGFIP validation?"
If they need to escalate it, you have your answer. If FEC is a premium tier, you have your answer. If they don't recognize the term, you have your answer.
Switching software now — when records are current, when there's no audit pressure, when your accountant can assist the transition — costs nothing. Switching under audit pressure, mid-inspection, is the most expensive version of the same decision. It's the version businesses that came through FEC failures remember. None of them would choose it again.

What audit-ready software looks like
Sage includes FEC export. It charges €3,000 or more per year. Liberté includes FEC export. It's free. Both treat FEC as baseline — not an optional module, not a compliance upgrade, not something you find out about during an inspection.
Any accounting software sold for use in France that can't produce a valid FEC file isn't really accounting software for France. It's invoicing software with an accounting label and a compliance gap at exactly the worst moment.
Liberté generates the FEC file automatically from your accounting records, in the background, updated continuously. When an audit notice arrives, producing the file takes minutes. The inspection runs on schedule. You go back to running your business. That's what the software is supposed to do.

Before the audit arrives
DGFIP inspection rates have increased for e-commerce businesses, service companies, and any business managing frequent digital transactions. Over a five-year business life, the probability of at least one inspection is real and rising. Audit readiness shouldn't depend on discovering a missing feature during that inspection.
One question to your accountant this week: "Does our accounting software generate a valid FEC file?" They already know the answer. If it's no, you now know what to do — and when to do it.
Choosing software that handles French compliance requirements as standard means that day, when it comes, stays exactly what it should be: a three-day inspection that concludes normally, and a week you've already forgotten by Friday.
