What EXCO does

EXCO is a privately-held French network of independent accounting, audit, tax, legal, payroll, and advisory firms structured as EXCO SAS, headquartered in Paris and tracing its earliest roots to 1946 (Exco Fiduciaire du Sud-Ouest). The network operates through approximately 140 offices across France and internationally, organized into regional partner-led groups including Exco Socodec, Exco Fiduciaire du Sud-Ouest, Exco Valliance, Exco Nexiom, Exco Omniconseils, Exco Hesio, and Exco Avec, with a federated ownership model anchored by President Bruno Geeraert. EXCO delivers a full-service professional services portfolio spanning accounting expertise, statutory audit, legal and tax advisory, payroll and HR management, CSR/sustainability verification (OTI third-party independent verification for CSRD compliance), carbon footprint assessment, M&A advisory (Exco Finance et Transactions), wealth management (Exco Gestion Privée), forensics, consulting, and international development support through Kreston International membership.

Revenue is generated primarily through quote-based professional services engagements, with recurring revenue streams from ongoing accounting, payroll, and compliance mandates, complemented by project-based advisory and transaction work. The customer base is horizontally segmented across TPE/PME, ETI/large enterprises, liberal professions, agriculture and agri-food, start-ups, and public sector entities, served through direct field-sales relationships at each member firm office and a client-facing digital portal (MyExco). Geographic presence spans France (Paris, Dijon, Toulouse, Champagnole, Vic-en-Bigorre, Biarritz, Bruges, and broader regional coverage) with international reach delivered via the Kreston network. The firm employs 501–1,000 professionals, with the largest documented regional subgroup (Exco Socodec) operating 6 offices with 9 partners and 130 employees in Bourgogne-Franche-Comté.
