What GMBA does

GMBA is a Paris-headquartered multi-discipline professional services firm operating in the French market, with roots tracing to GMBA Seleco (1961) and the Walter France network (1974). The firm delivers accounting, statutory audit, tax, legal, HR, and consulting services through a set of branded subsidiaries including GMBAvocats (legal), GMBA SMC (social/HR), GMBA Seleco (accounting), and GMBA Essonne (regional). Its client base spans entrepreneurs, SMEs, mid-market companies (ETIs), associations, cultural and creative-sector organizations, startups, and international subsidiaries of foreign groups operating in France — a deliberately diversified roster with no disclosed anchor logos.

Alongside its core fee-for-service practice, GMBA has built and operates proprietary SaaS platforms E-Gestion (accounting and management) and E-Gestion RH (HR/payroll), which embed clients into its technology stack and generate subscription revenue. The firm is a member of both the Allinial Global international accounting alliance and the Walter France multi-discipline network, providing cross-border referral capacity and shared service-line access. It holds the LUCIE RSE CSR label (first accounting-sector recipient in 2012, with subsequent renewals), the EcoVadis Silver Medal (2025), and Great Place to Work certification across 2023-2025, indicating deliberate positioning around ESG credentials and employer brand.

GMBA's revenue mechanics combine traditional project-based professional services fees (audit, tax, legal, HR mandates) with recurring SaaS subscription revenue from E-Gestion deployments. Headcount sits in the 101-250 range, positioning the firm as a mid-tier Paris-based multi-discipline player rather than a Big Four competitor. No public revenue figures are disclosed.
