Best billing software for nail technicians in 2026: the honest comparison
I compared 14 billing software options for nail technicians. Here are the real numbers on hidden commissions, NF525 certification, and how to choose based on your profile.
I counted. There are exactly 14 different solutions for managing your appointments, payments, and clients as a nail technician in France.
Some advertise €29/month. Others promise completely free access. And a handful charge you €89 excl. VAT per month with the argument that you 'have no choice'.
The problem? Almost every comparison guide out there tells you the same thing without giving you the real numbers.
I built software for nail technicians after talking with dozens of them. I've seen the real invoices. I've heard the frustrations. And I've understood that the most important question is not 'which software has the most features' — it's how much you're really paying at the end of the year.
This guide gives you the real numbers. The truth about hidden commissions. And a clear method to choose the right tool based on your profile — solo independent or a salon with multiple practitioners.
The truth about hidden commissions (and the calculation nobody does)
The first thing you see when searching for software is the advertised monthly subscription price. Treatwell: €29/month. Fresha: free. Planity: from €45/month.
What nobody clearly explains is the business model behind these numbers.
Treatwell and Fresha are marketplaces. Their real business model is finding you new clients — and taking a commission on every new client they bring you.
- Treatwell: 25% commission on every first appointment from a new client
- Fresha: 20% commission on each new client via their marketplace (since the 2025 pricing pivot)
Real scenario: you acquire 8 new clients per month, average basket €65
Treatwell: Subscription €29 | Commissions €130 | Real cost €159/month (€1,908/year). Nail Harmony Pro: Subscription €19 | Commissions €0 | Real cost €19/month (€228/year). Difference over one year: €1,680 — equivalent to 25 full services going directly to the platform.
The distinction nobody makes: are you solo or managing a salon?
75% of nail technicians work as independents — self-employed, at home, renting a booth, or mobile. Their needs are radically different from a salon manager with 3 practitioners.
The NF525 certified cash register myth
Since 2018, there's been a lot of talk about the obligation to use NF525-certified billing software. Since September 2025, rules have tightened: only NF525-certified software or software validated by an accredited body (LNE) is accepted.
But here's what many don't know: this obligation only applies to VAT-registered businesses. The 2025 VAT exemption threshold for services: €36,800 annual revenue. If you're below this threshold, you have NO obligation to have NF525-certified software.

Question 2: Do you work alone or with other practitioners? Alone → Solo solutions (Nail Harmony, NailBook Pro, Fleeky Pro). With others → Multi-practitioner software needed.
Question 3: Is no-show your main problem? Yes → Prioritize Fleeky Pro (bank imprint) or NailBook Pro (intensive reminders).
Question 5: What's your maximum monthly budget? Under €19 → Nail Harmony Free up to 20 clients. €19-30 → Nail Harmony Pro, NailBook Pro, Fleeky Pro. €30-60 → Booksy, Planity Essential. €60+ → Kiute Pro, Planity Premium.
Conclusion
The 'best' billing software for nail technicians in 2026 is the one that matches your profile and needs — not the one with the most features or the biggest advertising budget.
If you're solo under €36,800 revenue: you don't need NF525 certification, software between €15-30/month covers all your needs, avoid hidden marketplace commissions if you already have a loyal clientele.
