Vachon et Associes

What Vachon et Associes does

Vachon & Associés is an independent audit and public accounting firm (cabinet d'audit et d'expertise comptable) headquartered in Paris, France, founded in 1997. The firm is organized as a Société par actions simplifiée with four partners and approximately 40 collaborators, operating from a registered office at 54 Rue de Clichy (75009 Paris) and a working office at Square Louvois (1-3 Rue Lulli, 75002 Paris). It delivers multidisciplinary professional services across five core lines — Audit (French standards and IFRS), Expertise Comptable, Fiscalité, Paie, and Consolidation — supplemented by Due Diligence, Expatriate/Impatriate Tax Services, and CPA Services aligned to AICPA standards.

The firm's core technology is professional expertise rather than a software platform: bilingual (French/English) teams experienced in French GAAP, IFRS, and US GAAP, capable of serving both domestic SMEs and the French subsidiaries of foreign groups. There are no disclosed proprietary software products, applications, APIs, or AI-driven automation; service delivery rests on partner-led, bespoke engagements organized on an ad hoc basis.

Vachon generates revenue through professional services fees billed to clients for ongoing audit, accounting, tax compliance, payroll, consolidation, and advisory engagements. Its two principal customer segments are French SMEs/mid-market companies and French subsidiaries of international groups, reached through a direct engagement sales motion rather than channel partners. Marketing is limited to a bilingual SEO-optimized website and a LinkedIn company page. In April 2026, the firm entered an agreement to be acquired by professional services group S&W, which would mark a structural change in ownership and scale.
