What's different about running a trades business in France
French artisan software selection has structural differences from the US or UK. First, structured e-invoicing is becoming mandatory — from 1 September 2026 every business must be able to receive e-invoices, and from 1 September 2027 SMEs and micro-entreprises must issue them through an approved platform (PDP); the planned free public portal was scrapped, so software choice now carries compliance weight. Second, assurance décennale is mandatory — ten-year structural liability under the Loi Spinetta, required before a worksite opens, with a criminal penalty for working without it — and French clients expect your insurer and policy number on the quote. Third, TVA is multi-rate (20% standard, 10% renovation, 5.5% energy-renovation), so software must apply the right rate per line. Fourth, RGE certification is commercially essential: only RGE-qualified artisans let their clients claim MaPrimeRénov' and other renovation subsidies. And most solo tradespeople run as micro-entrepreneurs, with a VAT franchise and the "TVA non applicable, art. 293 B" invoice mention.
Devis-facture & job-management software
French-native BTP tools for quotes (devis), invoicing (factures) and worksite tracking — Obat and Tolteck for artisans, EBP and Batappli for fuller coverage, Organilog for maintenance rounds — all built around multi-rate TVA (20/10/5.5).
Obat
Tier S · RecommendedDevis-facture et suivi de chantier, pensé pour le bâtiment
A French-built quote-and-invoice (devis-facture) and worksite-tracking tool made specifically for building trades, with transparent pricing including a dedicated micro-entreprise tier — one of the cleanest BTP fits for a solo artisan or small crew.
France-specific note
A strong default for a French artisan who wants devis-facture done properly with the right TVA rates — and the micro-entreprise tier matches how most tradespeople are actually set up.
Pros
- + French-native, built for the BTP niche
- + Published pricing incl. a micro-entreprise tier
- + Devis → facture workflow done right
- + Multi-rate TVA (20/10/5.5) handled
Cons
- − Smaller than the big ERP publishers
- − Site/chantier depth lighter than heavy ERPs
- − Add-ons for advanced needs
- − French-market only
Tolteck
Tier S · RecommendedDevis & factures simples, conçus avec des artisans (et hors-ligne)
A French devis-and-invoice tool built with artisans, that works offline on site and is backed by Saint-Gobain Distribution Bâtiment France — simple, fast quoting for tradespeople who hate admin.
France-specific note
The pick for an artisan who wants the fastest possible devis with the least friction — and the offline mode genuinely matters on sites with no signal.
Pros
- + Made with artisans; very simple to use
- + Works offline on site
- + Flat, low published price (unlimited users)
- + Saint-Gobain backing
Cons
- − Owned by a building-materials distributor
- − Lighter on full chantier/ERP features
- − Quoting-first, not full project management
- − French-market only
EBP Bâtiment
Tier A · WorkableDevis, facture et chantier d’un éditeur français établi
The building edition of EBP, a long-established French business-software publisher — devis, invoicing and worksite management with the reassurance of a large local vendor and accountant familiarity.
France-specific note
A safe established-vendor choice, especially if your accountant already works in EBP — just note its e-invoicing runs through Cegid’s platform rather than its own.
Pros
- + Established French publisher (Cegid group)
- + Full devis/facture/chantier coverage
- + Familiar to many experts-comptables
- + Published entry pricing
Cons
- − Heavier/more complex than micro tools
- − Routes e-invoicing via Cegid’s platform (not its own PDP)
- − Per-user costs add up
- − More setup than a simple quoting app
Batappli
Tier A · WorkableLogiciel BTP tout-en-un avec la bibliothèque Batichiffrage
A French all-in-one BTP tool (publisher AGIRIS) with the Batichiffrage price library built in — useful for artisans who want ready-made priced works items rather than building every devis line from scratch.
France-specific note
The Batichiffrage library is the draw — if pricing works items accurately is your pain point, Batappli saves real time on every devis.
Pros
- + Built-in Batichiffrage price library
- + French BTP-specific
- + Tiered pricing for different sizes
- + Quote → invoice → chantier flow
Cons
- − Per-user pricing
- − Interface less modern than newer tools
- − Library value depends on your trade
- − French-market only
Mediabat
Tier A · WorkableDevis, facturation et chantier pour le BTP
A French quoting/invoicing/worksite tool for building trades with affordable published tiers — a workable mid-market option for small BTP firms.
France-specific note
A budget-friendly French BTP option worth shortlisting against Obat and Mediabat’s peers if price is the deciding factor.
Pros
- + French BTP-focused
- + Affordable published pricing
- + Covers devis, facture and chantier
- + Aimed at small firms
Cons
- − Smaller brand
- − Lighter ecosystem/integrations
- − Feature depth varies
- − French-market only
Vertuoza
Tier A · WorkableGestion tout-en-un bâtiment, avec saisie vocale par IA
An all-in-one construction-management tool (quotes, invoicing, worksite) with AI voice input, serving the French market from Belgium — modern and feature-rich, though pricing is quote-only and it’s not French-native.
France-specific note
Capable and modern, but it’s a Belgian product serving France — confirm its French e-invoicing (PDP) readiness and get a written quote before committing.
Pros
- + Modern all-in-one bâtiment platform
- + AI voice-input feature
- + Covers the full quote-to-site workflow
- + Active product development
Cons
- − Belgian, not French-native
- − No public pricing (quote-only)
- − Newer entrant in France
- − Confirm French e-invoicing/PDP path
Organilog
Tier A · WorkableGestion d’interventions et de maintenance sur le terrain
A French field-intervention and maintenance-management tool — strongest for trades doing recurring service/maintenance rounds (plumbing, HVAC, facilities) rather than one-off construction projects.
France-specific note
The pick for service/maintenance-led trades (chauffagistes, plombiers on contracts) rather than project builders — pair with a devis tool if you also quote big jobs.
Pros
- + French-native field-service tool
- + Free tier to start; clear per-user pricing
- + Strong for maintenance/intervention rounds
- + Mobile-first
Cons
- − Intervention-focused, lighter on devis-BTP
- − Per-user costs scale
- − Less suited to project/chantier billing
- − General, not BTP-specific
Axonaut
Tier A · WorkableGestion d’entreprise tout-en-un (facturation, CRM, trésorerie)
A French all-in-one small-business tool (invoicing, CRM, treasury) — not BTP-specific, but a solid general option for an artisan business that wants CRM and cash-flow alongside invoicing.
France-specific note
Better if you want CRM and treasury management than if you need BTP-specific quoting — many artisans pair a devis tool with general business software, and this is the latter.
Pros
- + French-native, broad SMB feature set
- + CRM + treasury + invoicing in one
- + Published pricing
- + Good for the business side beyond devis
Cons
- − General SMB, not BTP-specific
- − No building price libraries
- − Base price includes only 1 user
- − Less tailored to chantier work
Lead generation
French renovation marketplaces connecting homeowners to artisans — Habitatpresto (subscription, no commission), Quotatis (backed by Leroy Merlin), and the energy-renovation/RGE-angled Allotravaux.
Habitatpresto
Tier S · RecommendedMise en relation particuliers ↔ artisans vérifiés
A leading French renovation lead-gen brand connecting homeowners to vetted artisans on a subscription model — no per-devis charge and no commission on the work, which makes cost predictable.
France-specific note
The cleanest French renovation lead channel to try first — the no-commission subscription means a busy month doesn’t cost you more. Ask for cost-per-signed-job data before committing.
Pros
- + Strong French-native renovation brand
- + Subscription model (no per-lead/commission)
- + Vetted-artisan positioning builds trust
- + Predictable cost
Cons
- − Pricing not public (quote)
- − Lead quality varies by trade/region
- − Subscription commits you upfront
- − Competition among listed artisans
Quotatis
Tier A · WorkableMise en relation travaux, adossée au groupe ADEO (Leroy Merlin)
A French homeowner-to-artisan matching platform backed by Groupe ADEO (Leroy Merlin), also handling product-installation dispatch — strong consumer reach through its retail parent.
France-specific note
Worth testing alongside Habitatpresto — the Leroy Merlin connection drives real consumer volume, but measure cost-per-won-job since the model isn’t transparent upfront.
Pros
- + Backed by ADEO/Leroy Merlin (reach)
- + Renovation + product-install leads
- + Established French brand
- + Large homeowner audience
Cons
- − Pricing model not public (hybrid)
- − Lead quality varies
- − Retail-driven lead mix
- − Competitive
Travaux.com
Tier A · WorkablePlace de marché travaux (propriété US — groupe Angi/Instapro)
A large French-origin renovation marketplace now owned by the US-listed Angi (via Instapro), connecting homeowners and artisans on a pay-per-lead model with free registration.
France-specific note
Big reach, but it’s US-owned and pay-per-lead — set a strict budget and track cost-per-job, because shared leads can get expensive fast.
Pros
- + Large established marketplace
- + Free registration; pay-per-lead
- + High homeowner traffic
- + Broad trade coverage
Cons
- − US-owned (Angi/Instapro), not French-native
- − Pay-per-lead cost can mount
- − Leads often shared/contested
- − Per-lead price not public
StarOfService
Tier A · WorkablePlace de marché de services locaux (rénovation incluse)
A French (Paris) local-services marketplace where renovation is one vertical among many, on a credit / pay-per-quote model with optional subscription — broad but less BTP-focused than the pure renovation platforms.
France-specific note
Generalist rather than BTP-specialised — fine as a secondary channel, but the renovation-focused platforms usually convert better for building trades.
Pros
- + French-native marketplace
- + Credit/pay-per-quote flexibility
- + Wide service categories
- + Optional subscription
Cons
- − Not renovation-specialised
- − Lead quality varies widely
- − Pricing mostly secondary-sourced
- − Many trades compete per request
Allotravaux
Tier A · WorkableMise en relation travaux & rénovation (angle RGE/énergie)
A French homeowner-to-artisan renovation platform with an energy-renovation/RGE angle, on a pay-per-lead model — relevant if your work skews toward subsidised energy-renovation jobs.
France-specific note
Most useful if you’re RGE-qualified and chasing energy-renovation work — confirm which domain/brand you’re actually signing with, as the naming is ambiguous.
Pros
- + French renovation lead-gen
- + Energy-renovation / RGE angle
- + Pay-per-lead
- + Fits MaPrimeRénov’-driven demand
Cons
- − Pricing not public
- − Brand split (.com vs allo-travaux.fr) is confusing
- − Lead quality varies
- − Smaller than Habitatpresto/Quotatis
Payroll (paie)
URSSAF-compliant payroll for small French firms — PayFit direct-to-business, Silae via your expert-comptable, plus EBP and Sage. Check BTP specifics (caisses CIBTP) for building crews.
PayFit
Tier S · RecommendedPaie + RH en ligne (bulletins, DSN, congés) pour TPE/PME
A French cloud payroll and HR platform (payslips, DSN declarations, leave) sold directly to small businesses — the most accessible self-serve option, and the only payroll vendor here with full public pricing.
France-specific note
The easiest payroll to set up yourself. One caveat for builders: confirm it handles BTP-specific items (caisses de congés CIBTP, intempéries) for your situation before switching.
Pros
- + French-native, direct-to-SMB
- + Handles bulletins + DSN + congés
- + Full public self-serve pricing
- + 30-day free trial
Cons
- − Per-employee cost + base subscription
- − Not BTP-specific (no caisses CIBTP/intempéries advertised)
- − Less suited to very large headcounts
- − Payroll/HR only
Silae
Tier A · WorkableMoteur de paie dominant, via experts-comptables
The dominant French payroll engine by volume (millions of payslips monthly), with 900+ collective agreements — but sold through accountants (experts-comptables), not direct, so you access it via your firm.
France-specific note
If you already use an expert-comptable, you may effectively be on Silae — its BTP convention coverage is excellent. It’s the accountant-led route rather than a DIY tool.
Pros
- + Market-leading French payroll engine
- + 900+ conventions collectives (incl. BTP)
- + Deep compliance coverage
- + Backed by your accountant
Cons
- − Not sold direct (via experts-comptables only)
- − No public pricing
- − Less hands-on for the business owner
- − Setup depends on your firm
EBP Paie
Tier A · WorkablePaie et déclarations sociales pour TPE/PME
The payroll module from French publisher EBP — payroll and social declarations for small firms, a natural fit if you already run EBP Bâtiment for your devis and invoicing.
France-specific note
Most compelling if you already run EBP Bâtiment — keeping devis, invoicing and payroll in one publisher reduces friction. Otherwise PayFit is the easier standalone.
Pros
- + French publisher; integrates with EBP suite
- + Payroll + social declarations
- + Familiar to accountants
- + Good if already on EBP
Cons
- − Pricing on quote ("sur devis")
- − Less modern than cloud-native PayFit
- − Best value inside the EBP ecosystem
- − Setup effort
Sage Paie
Tier A · Workable Cross-marketPaie en ligne pour petites entreprises
Sage’s French online payroll for small businesses — the one non-French-founded payroll option here, with the reassurance of a global brand and a large accountant ecosystem.
France-specific note
A credible global-brand alternative to the French-native options — but for a small French artisan, PayFit’s self-serve simplicity usually wins unless your accountant standardises on Sage.
Pros
- + Global brand, large accountant network
- + Online payroll for small firms
- + Established compliance track record
- + Published entry pricing (snippet)
Cons
- − Not French-founded (UK-HQ)
- − Less TPE-friendly than PayFit direct
- − BTP specifics to confirm
- − Pricing page access was limited
Insurance — décennale & RC Pro
Mandatory ten-year decennial cover and pro liability — SMABTP (the historic BTP mutual), the per-trade specialist April, online insurtech Orus, plus AXA and MAAF.
SMABTP
Tier S · RecommendedL’assureur mutualiste historique du BTP — décennale + RC Pro
The historic French BTP mutual insurer (since 1859) and the reference for artisan décennale — bundling mandatory ten-year decennial liability with RC Pro, with deep building-sector specialism.
France-specific note
The incumbent every French builder knows for décennale. Get a SMABTP quote as your benchmark, then compare the insurtechs (Orus, April) on price and speed.
Pros
- + The reference for BTP décennale
- + Mutual, BTP-specialist since 1859
- + Décennale + RC Pro bundled
- + Deep claims/sector expertise
Cons
- − Quote-only (no online pricing)
- − Premiums reflect specialist cover
- − Application/underwriting process
- − Less "instant" than insurtechs
April Construction
Tier S · RecommendedRC Décennale sur mesure par métier, prix « à partir de » publiés
A French insurer/broker offering décennale tailored per trade (up to 10 activities) — and one of the few publishing indicative "à partir de" pricing, which makes it easy to benchmark.
France-specific note
A strong décennale benchmark precisely because it publishes starting prices — useful to sanity-check a SMABTP or AXA quote before you sign.
Pros
- + BTP décennale specialist
- + Per-trade tailoring (up to 10 activities)
- + Publishes indicative pricing
- + Established French brand
Cons
- − Final price still needs a quote
- − Broker/MGA model
- − Cover scope varies by trade
- − Add-ons for full protection
Orus
Tier A · WorkableDécennale 100% en ligne, attestation sous 24h
A French insurtech offering fully online décennale across 100+ BTP trades with an attestation issued within 24 hours and published starting prices — the fast, modern route to mandatory cover.
France-specific note
The quickest way to get compliant décennale cover if you need an attestation fast — just compare its cover scope against SMABTP for bigger or higher-risk work.
Pros
- + Fully online; fast (attestation in 24h)
- + Covers 100+ BTP trades
- + Published starting price
- + Modern, low-friction experience
Cons
- − Insurtech (younger than incumbents)
- − Final price by quote
- − Cover depth vs specialists to compare
- − Online-first support
AXA (BATISSUR)
Tier A · Workable Cross-marketDécennale et multirisque BTP (offre BATISSUR)
AXA’s building offer (BATISSUR) provides décennale and multirisk BTP cover with the backing of a major global insurer — a mainstream alternative to the BTP mutuals.
France-specific note
A solid mainstream option, especially if you already bank/insure with AXA — but benchmark it against the BTP specialists (SMABTP) and the insurtechs (Orus/April) on both price and cover.
Pros
- + Major global insurer
- + Décennale + multirisk BTP
- + Wide agent network
- + Brand stability
Cons
- − Quote-only
- − Less BTP-specialist than SMABTP
- − Agent-led process
- − Pricing opaque until quoted
MAAF Pro
Tier A · WorkableMutuelle généraliste avec solutions décennale artisan
A French generalist mutual (Covéa group) offering artisan décennale solutions — a familiar mainstream name for tradespeople who want one insurer across pro and personal lines.
France-specific note
Convenient if you want pro and personal cover under one familiar mutual — but for décennale specifically, benchmark against the BTP specialists before deciding.
Pros
- + Established French mutual (Covéa)
- + Artisan décennale solutions
- + Wide branch network
- + One-insurer convenience
Cons
- − Quote-only
- − Less BTP-specialist than SMABTP
- − Cover scope varies
- − Pricing opaque
Compliance & qualifications
What French artisans must navigate — the facturation électronique mandate, mandatory assurance décennale, RGE for subsidised work, multi-rate TVA, URSSAF/micro-entrepreneur, CMA registration and trade qualifications.
Facturation électronique (e-invoicing)
Official body / regimeFacturation électronique obligatoire via une plateforme agréée (PDP)
France is moving all B2B invoicing onto government-regulated structured e-invoicing through approved platforms (PDP / "plateformes agréées"): reception becomes mandatory for ALL businesses on 1 September 2026, and issuance reaches SMEs and micro-entreprises (most artisans) on 1 September 2027.
France-specific note
The defining French software change: from Sept 2026 you must be able to RECEIVE e-invoices, and from Sept 2027 you must ISSUE them via a PDP. See our facturation-électronique guide for the registered platforms. The free public portal was abandoned — every business needs a PDP.
What it covers
- + Single national e-invoicing framework
- + Approved-platform (PDP) routing + e-reporting
- + Phased, signposted calendar
- + Pilot phase already running (since Feb 2026)
Watch out for
- − Reception mandatory for ALL by 1 Sept 2026
- − Issuance mandatory for artisans by 1 Sept 2027
- − You must use an approved platform (PDP)
- − The free public portal (PPF) was scrapped — no free issuance route
Assurance décennale (Loi Spinetta)
Official body / regimeAssurance responsabilité décennale — obligatoire avant tout chantier
Mandatory ten-year decennial-liability insurance under the Loi Spinetta (Code des assurances L241-1), taken out BEFORE a worksite opens. It covers, for 10 years, damage compromising the structure’s solidity or making it unfit for purpose — and working without it is a criminal offence.
France-specific note
Non-negotiable for French building work — and uniquely central: French clients expect your décennale insurer and policy number on the quote. Get cover before you start, not after.
What it covers
- + Protects clients (and you) for 10 years
- + Legally mandatory — a market entry requirement
- + Routinely shown on devis/factures (trust signal)
- + Covers structural + indissociable equipment
Watch out for
- − Criminal penalty if uninsured: 6 months + €75,000
- − Must be in place before the worksite opens
- − Premiums vary widely by trade/risk
- − Per-activity cover scope to get right
RGE (Reconnu Garant de l’Environnement)
Official body / regimeLabel qualité — indispensable pour les aides à la rénovation énergétique
A quality label (awarded by Qualibat, Qualit’EnR, Qualifelec and others) that isn’t legally required to operate — but is commercially essential, because the homeowner can only claim MaPrimeRénov’, CEE or éco-PTZ subsidies if the installer holds the relevant RGE qualification.
France-specific note
In the subsidy-driven renovation market keeping the sector afloat, RGE is effectively the price of entry: no RGE means your clients can’t get the aid, so they’ll pick an installer who has it.
What it covers
- + Unlocks client access to MaPrimeRénov’/CEE/éco-PTZ
- + Strong commercial advantage in renovation
- + Signals quality to homeowners
- + Multiple trade-specific qualifications
Watch out for
- − Not mandatory to operate (but you lose subsidised work)
- − Qualification + annual monitoring + cost
- − 4-year validity to maintain
- − Trade-specific sub-labels to navigate
TVA bâtiment (20 / 10 / 5,5 %)
Official body / regimeTVA à taux multiples — 20% standard, 10% rénovation, 5,5% énergie
French building work uses multiple VAT rates: 20% standard, a reduced 10% for renovation/improvement, and 5.5% for energy-renovation work — applicable to dwellings over two years old, with conditions, and (since March 2025) excluding fossil-fuel boilers.
France-specific note
Your software must apply 20/10/5.5 correctly per line and carry the rate-justification mention on the devis — getting the reduced rate right is both a compliance duty and a competitive price advantage.
What it covers
- + Reduced rates lower client cost (sales advantage)
- + Standard for renovation work
- + Clear official guidance
- + Built into good French BTP software
Watch out for
- − Per-line rate logic is complex
- − Conditions: >2-year-old dwelling, work type
- − Fossil-fuel boilers excluded since March 2025
- − Errors create VAT-recovery problems
URSSAF & régime micro-entrepreneur
Official body / regimeCotisations sociales et régime auto-entrepreneur
URSSAF collects social contributions (cotisations sociales). A large share of French tradespeople operate as micro-entrepreneurs — turnover-based contributions, simplified accounting and (below the threshold) a VAT franchise — declared via the URSSAF auto-entrepreneur portal.
France-specific note
Most solo French artisans are micro-entrepreneurs, so your software must support both the micro regime (incl. the "TVA non applicable, art. 293 B" mention) and full-VAT sociétés as you grow.
What it covers
- + Simplified regime for solo artisans
- + Turnover-based contributions
- + VAT franchise below the threshold
- + Online declaration portal
Watch out for
- − Turnover ceiling (~€83,600 services, 2026)
- − VAT franchise thresholds shifted in 2025
- − Franchise invoices need the art. 293 B mention
- − Above ceiling → full regime + VAT
Immatriculation CMA (guichet unique / RNE)
Official body / regimeImmatriculation de l’entreprise artisanale (guichet unique → RNE → SIRET)
Registering an artisan business goes through the INPI guichet unique into the Registre National des Entreprises (RNE), producing a SIRET; the Chambre de Métiers et de l’Artisanat (CMA) validates artisanal qualification. Registration is mandatory.
France-specific note
Your SIRET from this registration is what lets you legally invoice — and for regulated trades the CMA will check your qualification (diploma or 3 years’ experience).
What it covers
- + Single national registration route
- + Produces your SIRET (needed to invoice)
- + CMA validates artisan qualification
- + Online via the guichet unique
Watch out for
- − Registration mandatory before trading
- − Qualification proof for regulated trades
- − Process/documentation steps
- − CMA validation can add time
Qualification professionnelle (Code de l’artisanat)
Official body / regimeDiplôme ou 3 ans d’expérience pour les métiers réglementés
Several building trades are regulated: you must hold a relevant qualification (a CAP/BP diploma) OR prove three years’ professional experience to run the business, under the Code de l’artisanat (L121-1 to L121-3).
France-specific note
For regulated trades (e.g. électricien, plombier doing building work), you must show the qualification at registration — the experience route (3 years) exists if you don’t hold the diploma.
What it covers
- + Quality bar for regulated trades
- + Diploma OR 3 years’ experience route
- + Protects consumers
- + Clear legal basis (Code de l’artisanat)
Watch out for
- − Mandatory for regulated trades
- − Must be proven at registration
- − Experience route needs documentation
- − Trade-specific requirements
Qualibat
Official body / regimeQualification/certification volontaire — et organisme RGE de référence
A voluntary French qualification and certification body for building firms — not legally required, but a recognised quality mark and one of the leading bodies that awards RGE, so often de-facto needed for larger or subsidised work.
France-specific note
Voluntary, but valuable: a Qualibat qualification is a trust signal, and Qualibat is a main route to RGE — so it often pays for itself on subsidised renovation work.
What it covers
- + Recognised quality/qualification mark
- + A leading RGE-awarding body
- + Signals capability to clients
- + Useful for tenders/larger work
Watch out for
- − Voluntary (not a legal requirement)
- − Qualification process + fees
- − Maintenance/renewal
- − Value depends on your work type
