Sage Has 300,000 Customers in France. Their Renewal Rate Is 94%. That's Not Loyalty — It's Lock-In.
Switching Cost Architecture in Legacy Accounting Software Markets
---
The renewal email arrives in your inbox from Sage. €150 for another month. You're not thrilled — the interface is dated, the software is slow, and you've heard there are free alternatives. You open a browser tab, search "Liberté comptabilité," look at the migration process, see "8 years of accounting history," and close the tab. You click renew.
Winning loyalty and winning inertia are different things. This is inertia.

What a 94% Renewal Rate Actually Means
Sage has 300,000 customers in France and a 94% annual renewal rate. In most software markets, 94% renewal means customers love the product. In markets built on switching costs, it means something different: customers can't afford to leave.
Ask the question precisely: of the 282,000 Sage customers who renewed this year, how many actively chose to stay — and how many renewed because leaving was more trouble than it was worth?
Their pricing has been in the same range for over a decade. Their renewal rate has moved very little during that time. Those two facts are more connected than their marketing suggests.
With 300,000 customers paying up to €200/month, Sage generates roughly €400 million per year in French subscription revenue. Maintaining that revenue doesn't require building a better product. It requires making sure that the cost of leaving is always slightly higher than the cost of staying. That's a different engineering challenge — and Sage has been solving it for 30 years.

Three Layers of Lock-In You Didn't Know You Were Building
Lock-in isn't one thing. It's three things, all accumulating simultaneously.
Data lock-in: your five, eight, fifteen years of bookkeeping are stored in Sage's proprietary format. Moving to a new platform requires exporting that history, reformatting it, validating it, and importing it into the new system. Every year you stay on Sage, this problem grows larger. This is not an accident — it's architecture.
Accountant lock-in: your expert-comptable (your accountant, the person you rely on for advice, tax filings, and annual accounts) learned Sage and charges accordingly. When you ask about switching platforms, many accountants say they don't know the alternative well, and quote a fee for migration support. A new system means retraining. Retraining costs time. Time costs money.
Habit lock-in: your monthly routine — logging invoices, matching payments, running payroll — is built around Sage's specific interface and workflow. Changing software means rebuilding those habits from scratch. That feels like more disruption than it actually is, but it feels real when you're three weeks from a quarterly declaration.
All three have to break at once for the switch to happen. Sage knows that.

The Calculation They Want You to Make
Each year, the calculation is the same: annual Sage subscription (€1,800/year at €150/month) versus migration disruption (1-3 weeks plus accountant fees for migration support). Most years, disruption wins. Most years, you click renew.
What the calculation relies on: the migration feeling bigger than it is. In reality, Sage is legally required to provide a complete data export. That export format is the FEC — the Fichier des Écritures Comptables, a standardized accounting file every French business has by law. Liberté is built to import a Sage FEC directly. The migration from Sage to Liberté is typically a weekend, not three weeks.
That gap between "how long it feels like it will take" and "how long it actually takes" is exactly the gap Sage profits from every year.

What Staying Has Cost
Six years on Sage at €150/month is €10,800. A genuinely free alternative that covers the same functions — invoicing, payroll, bank reconciliation, government declarations — has existed for the last two of those six years. The €3,600 paid in those two years is the exact price of inertia: €3,600 to avoid a migration that takes a weekend.
Most business owners don't look at the number this way. The monthly fee feels like a cost of doing business, like electricity or phone. €150 disappears into the operating expenses without much resistance. €10,800 concentrated in one line item is harder to ignore.
You didn't sign up for Sage because your business needed €10,000 in accounting software. You signed up because at the time, it was the option in front of you. The situation has changed. The subscription hasn't noticed.

Testing Your Own Lock-In
One honest question: if switching to a free alternative were completely free and took two hours, would you do it?
Answer yes — and you're still on Sage — and you've identified your lock-in precisely. The switching cost is the only thing keeping you there. Not product quality. Not features. Not satisfaction.
Try a practical test: log into Sage and search for the full data export option. Time how long it takes to find it. Then contact your accountant and ask what they'd charge for migration support. Those two numbers tell you your actual switching cost — and whether it matches what you've been imagining.
For most small businesses, the first number is "about 45 minutes" and the second is "€200-400 for the accountant to validate the import." That's the total migration cost you've been comparing against €1,800 per year for years.

What Liberté Is Built to Do
Liberté imports the FEC export from Sage directly. That's not a workaround — it's the designed path, because the FEC is the standardized format French law requires every accounting platform to produce. You export from Sage once. You import into Liberté. Your history is there.
Beyond that: Liberté connects directly to the same government APIs your current software uses — net-entreprises.fr for payroll declarations (DSN — the monthly social security report companies send for each employee), autoentrepreneur.urssaf.fr for social contributions, impots.gouv.fr for TVA (VAT) and income filings. Nothing from your compliance workflow breaks. The declarations that happened on Sage continue to happen on Liberté. The price goes from €150/month to €0.
Liberté's design assumes you might want to leave someday. There's a complete data export, clearly documented. The same exit you struggled to find on Sage.

The Math Going Forward
Switching from Sage to Liberté saves between €960 and €2,400 per year, depending on your current plan. Over five years, that's between €4,800 and €12,000 — real money for a small business. Over ten years, it's a salary.
Every year you wait adds another year of records to the eventual migration. Acting now, before the next annual cycle closes, is the lowest-friction version of a decision you'll make eventually. The migration will feel anticlimactic when you finally do it. That's the part Sage doesn't advertise.

What the 94% Renewal Rate Tells You
A 94% renewal rate is not evidence that the product is excellent. It's evidence that leaving is inconvenient — and that Sage has built its business on that inconvenience for three decades.
Confident vendors make switching easy and invite you back if you prefer it. Confident vendors don't hide their export functions. Confident vendors don't price their service just under the migration pain threshold.
Mild despair when the renewal email arrives — "€150 again, what can I do" — is the sound of lock-in. You do not have to feel that. The migration you have been avoiding is a weekend.
