The French accounting software market has a rare characteristic in B2B: the end user (the accounting firm) is also the distribution channel for its own clients (SMEs). This dual role explains why vendor business models have diverged so sharply since 2020 — and why Pennylane’s arrival forced the incumbents into a fundamental strategic rethink.
In 2026, market consolidation is accelerating. ACD’s acquisition by Italian group TeamSystem in March 2026, Pennylane’s €175 million fundraise in January 2026, and the ongoing migration of firms still running Quadratus toward Cegid Loop are reshaping a landscape that firm directors and partners must understand before making any investment decision. This comparison structures the analysis across five relevant solutions, with concrete recommendations by firm profile.
The French Accounting Software Market: A Duopoly Under Disruption
Cegid and ACD: The Two Historic Blocs
For twenty years, the French accounting production market has operated around two dominant vendors.
Cegid consolidated the segment through successive acquisitions — including Quadratus (acquired in 2003 and progressively absorbed into the Loop platform) and CCMX. Its flagship product for accounting firms, Cegid Loop (formerly Cegid Expert), has established itself as the reference tool among mid-size and large firms. Native regulatory compliance — FEC (France’s mandatory audit file standard), liasse fiscale (statutory tax return package), DSN (payroll and HR reporting), and e-invoicing — along with deep functional coverage for statutory audit (commissariat aux comptes) and advisory missions are its structural advantages.
ACD Groupe has long played a credible challenger role, with a solution particularly valued by firms of 5 to 50 staff for its value-for-money ratio and ease of onboarding. With approximately €37 million in revenue, 350 employees, and 3,500 partner firms representing 30,000 users (TeamSystem, acquisition press release, April 2026), ACD was a solid, professionally recognised alternative.
On 31 March 2026, everything changed: TeamSystem — an Italian software group with over €1 billion in revenue, owned by US fund Hellman & Friedman — completed the acquisition of ACD (Herbert Smith Freehills Kramer, April 2026). A coherent strategic move: TeamSystem is replicating in France the model it deployed in Italy during the e-invoicing mandate, acquiring links in the chain before mandatory requirements trigger a wave of demand. Éric Choteau-Laurent, ACD’s president, remains at the helm of the French entity. The ACD brand and French operations are maintained.
Pennylane: The Fintech Disruption
Founded in 2020 by Arthur Waller, Pennylane built a fundamentally different model: the accounting firm is not the final target but the distribution channel. Pennylane acquires its SME clients through partner accountants who recommend the tool to their own clients.
In January 2026, Pennylane closed a €175 million Series E round from TCV and Blackstone, backed by DST Global, CapitalG, and Meritech Capital, valuing the company at €3.5 billion (Maddyness, 20 January 2026). The company now counts over 6,000 partner firms and has crossed €100 million in ARR (annual recurring revenue), achieving “centaur” status in the French tech ecosystem.
This financial firepower funds two priorities: accelerating AI development (accounting automation agents, intelligent coding) and European expansion ahead of the rollout of mandatory e-invoicing obligations across the EU.
Do the Big Four Use These Tools?
No. The eight or ten largest global networks (Deloitte, KPMG, PwC, EY, Mazars, BDO, Grant Thornton, RSM) have built proprietary platforms or integrate specialised audit solutions (TeamMate, Caseware, Galvanize) with no relation to the SME-focused accounting production tools covered here. This comparison is exclusively relevant for independent firms, regional networks, and practices of 1 to 200 staff.
The Five Solutions in Detail
Cegid Loop (formerly Cegid Expert): The Market Reference
Cegid Loop is Cegid’s cloud-native accounting and tax production platform, designed specifically for accounting firms. It covers the full spectrum: accounting, review, statutory tax returns, statutory audit, payroll, practice management, and client portal.
What sets it apart:
- Broadest functional coverage in the market for complex engagements (statutory audit, restructuring missions, multi-practice groups, multi-site operations)
- Native and up-to-date regulatory compliance: FEC, statutory tax returns, DSN, e-invoicing, tax attestation
- Integrated collaborative client portal (Loop Client) for document collection, e-signature, and engagement tracking
- Open Banking connectors for automatic bank statement retrieval
- Embedded AI for automatic transaction coding and anomaly detection
Its limitations:
- Perceived as more complex to navigate than ACD or Pennylane for small firms
- Non-public pricing, on request, with a per-managed-entity billing model. Field estimates suggest ranges of approximately €250–600 per month depending on modules and dossier volume, but without a published tariff, direct comparison is difficult
- Migration from Quadratus: technically feasible via Cegid’s RDD migration tool, but demanding — counterpart data, parameters, allocation rules, and access rights must all be migrated
Ideal profile: Firms of 10+ staff with diversified engagements including statutory audit, tax compliance, and advisory. Multi-site or group practices.
ACD Suite Expert (now TeamSystem France): A Solid Challenger in Transition
ACD’s Suite Expert covers accounting production, taxation, payroll, practice management, and document management (DMS) in a fully integrated platform developed specifically for French accounting firms for over 40 years.
What sets it apart:
- Onboarding widely recognised as faster than Cegid Loop — particularly valued by firms under 50 staff
- Full coverage of French statutory requirements (FEC, tax returns, DSN, e-invoicing)
- Per-staff billing model (not per dossier) — more predictable for practices with variable dossier volumes
- Support and proximity: French teams maintained post-acquisition, offices in Tours and Aix-en-Provence
What changes with TeamSystem:
The acquisition shifts the medium-term positioning. TeamSystem will bring AI capabilities (advanced OCR, automation agents, analytics) and European exposure. In the short term (12–24 months), service continuity is assured and French governance maintained. Over a longer horizon, integration into the TeamSystem ecosystem — which includes Sellsy, ClicData, and Clementine in France — could create meaningful synergies for practices looking beyond pure accounting production.
Ideal profile: Firms of 5 to 50 staff with diversified accounting production, sensitive to value-for-money and proximity support. Practices wanting a proven tool without Cegid’s pricing complexity.
Quadratus (Acquired by Cegid in 2003): What Happens to It?
Quadratus, acquired by Cegid as far back as 2003, is no longer an independent product. Cegid has progressively merged Quadratus functionality into the Loop platform, which is now the official convergence target for all firms still running Cegid Quadra (the former product name).
For firms delaying migration, the risk is real: Cegid concentrates its investment in Loop, not in maintaining the legacy Quadra interface. New capabilities (AI, Open Banking, advanced e-invoicing) arrive on Loop first. Migration is technically supported by Cegid’s RDD tooling, but demands serious preparation: accounting data migration, business rule reconfiguration, and staff training.
Key takeaway: If your firm runs Quadra, the question is no longer whether to migrate to Loop, but when — and how to de-risk the project.
Pennylane: The Fintech Challenger
Pennylane occupies a distinct place in this comparison: it is not, strictly speaking, an accounting production platform in the classical sense, but a financial management platform that integrates accounting, treasury, invoicing, and financial analytics from a single tool.
Its commercial model is its most defining characteristic: Pennylane charges the firm (base licence around €79/month, plus €15–40 per client dossier depending on volume and automation), and since January 2025, it shares a portion of revenue generated by its business banking product (interchange commissions, deposit remuneration) with partner firms as a licence rebate. A firm deploying Pennylane with 50 clients therefore generates supplementary income, in addition to productivity gains.
What sets it apart:
- Very fluid user experience, modern design, fast onboarding for junior staff
- Native Open Banking connections, OCR automation, and intelligent transaction coding
- Included client portal with real-time view of the client’s P&L and cash position
- Very active AI roadmap (autonomous accounting automation agents announced for 2026–2027)
- Business model aligning the firm’s interests with the vendor’s
Current limitations:
- Functional maturity still lower on complex engagements: statutory audit, detailed statutory tax returns, multi-entity group management
- Statutory audit coverage not on the short-term roadmap
- Fast-growing but relatively recent adoption: limited field evidence from 50+ staff firms running at 100% on the platform
Ideal profile: Firms pursuing aggressive digital transformation, focused on SME clients with accounting and advisory mandates, 1 to 30 staff. Practices wanting to align their production tool with their clients’ own management platform.
Sage for Accountants: The Option for Firms in the Sage Ecosystem
Sage for Accountants (sold in France as Sage Génération Experts) primarily targets firms whose clients are already equipped with Sage on the business management side (Sage 50, Sage 100, Sage Compta). More than 5,500 accounting firms in France use a Sage solution (Sage.com), many driven by the natural continuity of the client ecosystem.
What sets it apart:
- Seamless integration with client dossiers under Sage 50 or Sage 100: direct import of journal entries, no re-keying
- Full FEC, statutory tax, DSN coverage
- Sage prepares partner firms for the 2026 e-invoicing mandate with dedicated training and tools
- Strong commercial presence and a recognised support network
Its limitations:
- Less relevant for firms whose clients run other platforms (Odoo, Pennylane, Evoliz, Axonaut)
- UI and AI roadmap perceived as less dynamic than Pennylane on the automation front
Ideal profile: Firms with a client base historically on Sage, where ecosystem continuity is a determining selection criterion.

Recommendations by Firm Profile
Firms of 1 to 10 Staff — Generalist
Pennylane or ACD depending on digital maturity. Pennylane if the firm targets modern SME clients and wants a commercial differentiator; ACD if traditional accounting production is the priority and value-for-money is the lead criterion. Sage if clients are predominantly on Sage products.
Firms of 11 to 50 Staff — SME-Focused
ACD or Cegid Loop. ACD for its pricing transparency and ease of use; Cegid Loop if the firm has statutory audit engagements or large-account clients requiring greater functional depth. Pennylane as a complement or client acquisition channel rather than a primary production platform at this stage.
Firms of 50+ Staff, Multi-Site, Specialist Engagements
Cegid Loop without hesitation. The functional depth for statutory audit, multi-site management, and multi-entity group coverage has no accessible equivalent among the other solutions in this comparison.
Firms Pursuing Aggressive Digital Transformation
Pennylane as the priority. The combination of a unified platform (accounting production + treasury + invoicing for clients) and a business model aligned with the firm’s interests is a unique differentiator. Firms that have made this choice report reduced data entry and chasing time, and stronger client engagement through the real-time financial portal.
The 3 Questions to Ask Before Choosing
1. Do you carry out statutory audit engagements (commissariat aux comptes)? If yes, the question is closed: Cegid Loop or ACD. Pennylane is not in contention — its roadmap does not include a statutory audit module.
2. Are your clients on Sage, Odoo, or migrating to Pennylane? The client ecosystem is an underrated criterion. A firm where 70% of clients run Sage 50 has a structural argument for staying within the Sage ecosystem. Conversely, a firm accompanying growth-stage SMEs toward modern tools has every reason to master Pennylane.
3. What is your transformation horizon? A firm planning to change tool within the next six months should look at ACD (faster deployment, French teams maintained, post-acquisition continuity confirmed). A firm projecting five years ahead must factor AI into the decision: Pennylane and TeamSystem (ACD) are investing heavily on that front, while Cegid Loop relies on a broader functional base but has historically moved more slowly on innovation pace.
