ACG - Audit Consulting Group

What ACG - Audit Consulting Group does

ACG - Audit Consulting Group is a France-based, independent professional services firm headquartered in Toulouse, delivering accounting, tax, payroll, statutory audit, business valuation, and digital advisory services to small and medium enterprises, liberal professionals, artisans, merchants, non-profits, and individuals. The firm is owned and operated by five associates — Jérémie Castelnau, Jean Chenebeau, Sébastien Gasc, Violaine Savant-Ros, and Hélène Soenen — three of whom hold dual Expert-comptable and Commissaire aux Comptes certifications. With approximately 13 employees, a single Toulouse office at 225 Avenue de Lardenne, and a portfolio of around 70 audit mandates, ACG operates as a relationship-driven, partner-led practice under the France Défi national network.

The firm's technological stack is built on standard professional services software (ODOO ERP and Silae payroll) layered with the proprietary TEEMSI client portal for secure document exchange and online service delivery, plus the FD Académie e-learning environment shared across the France Défi network. Its service portfolio spans six lines: Comptabilité & Fiscalité, Paie/RH & Gestion Sociale, Valorisation d'Entreprise & Accompagnement Bancaire, Gestion Administrative & Direction Financière Externalisée, Commissariat aux Comptes & Rapport de Durabilité (CSRD), and Optimisation Digitale. CSRD certification positions the firm to capture sustainability audit mandates as EU reporting requirements roll out.

ACG's revenue model is primarily subscription-based across recurring accounting, payroll, and audit retainers, supplemented by project-based advisory work for business valuation, financing, and digital transformation. Client acquisition is sales-led through direct engagement, the firm website, LinkedIn, the Experts et Décideurs content platform, and referrals. Pricing is quote-based and customized to engagement scope, with progressive tiered packaging for payroll services. Distribution is exclusively direct from the Toulouse office, with no intermediaries or resellers, and geographic reach is concentrated in the Occitanie region with national coverage enabled through France Défi network affiliations.

Expansion highlights5 records

Direct peers

• Fiducial: Large French accounting, audit, and business services firm with a strong SMB and small-business book. Overlaps with ACG across accounting, payroll, legal, and advisory services for TPE/PME clients, though at much greater scale and with proprietary technology investments.
• In Extenso: French network of independent accounting and consulting firms serving SMEs, TPE/PME, and regulated professions nationwide. Closely comparable to ACG in customer segmentation (entrepreneurs, liberal professionals, artisans) and service mix (accounting, payroll, audit, advisory), but with significantly broader geographic reach across France.
• Grant Thornton France: French member of the Grant Thornton international mid-tier network offering audit, tax, and advisory services. Comparable to ACG in serving mid-market clients with a relationship-led model, but with materially larger resources and cross-border capabilities.
• RSM France: French member of the RSM international mid-tier accounting network, providing audit, tax, and consulting to mid-market companies. Comparable to ACG in offering integrated professional services with mid-market focus, though with broader geographic coverage and a stronger advisory practice.
• Baker Tilly France: French mid-tier accounting and advisory network (STC and Orfis merged under the Baker Tilly banner). Competes with ACG in statutory audit, accounting, and advisory for SMEs and mid-market firms, especially in regional French markets.

Broad incumbents

• Deloitte France: Big Four professional services firm in France serving clients from SMEs to large enterprises across audit, consulting, tax, and advisory. Represents the upper bound of competition for ACG's audit and advisory engagements, particularly when SME clients scale into mid-market.
• KPMG France: Big Four professional services firm in France with audit, tax, and advisory practices covering SMB through large-cap segments. Overlaps with ACG in statutory audit and SME advisory but at vastly greater scale, brand recognition, and technology investment.
• BDO France: French arm of the BDO international accounting network, providing audit, accounting, tax, and advisory across all major French cities. Competes for the same mid-market and SME audit/advisory engagements as ACG but at significantly greater scale, geographic reach, and cross-functional depth.
• Forvis Mazars France: French operations of the Forvis Mazars global mid-tier network, offering audit, tax, and advisory. Overlaps with ACG on statutory audit and SME advisory mandates but competes from a substantially larger resource base and international footprint.

Others

• France Défi: National French network of independent accounting firms under whose umbrella ACG operates. Not a direct competitor but rather an affiliated platform providing shared branding, content, and learning resources; included here because other member firms within the same network are ACG's closest operational peers.
