What In Extenso Centre-Est does

In Extenso Centre-Est is a regional French accounting and advisory practice within the broader In Extenso network, headquartered in Besançon, Bourgogne-Franche-Comté, employing 51-100 professionals. It delivers the full suite of In Extenso services to its territory: accounting and bookkeeping, tax compliance and optimization, payroll and social security management, legal advisory, statutory audit (Commissariat aux Comptes), business creation and takeover advisory, M&A and business transmission, international development support, and wealth management — with additional sector-specific capabilities in agriculture, hospitality, tourism, social economy, franchise networks, and liberal professions.

The firm's technology backbone is Inexweb, a proprietary client management portal offering sector-specific modules (building/trades, automotive, retail, wholesale, point-of-sale), supplemented by business intelligence dashboards (Dashboard Essentiel) and an Electronic Invoice Compliance (ECF) tool aligned with France's mandatory 2026 e-invoicing regime. The wider In Extenso platform includes multiple subsidiary brands — In Extenso Avocats (legal), In Extenso Social (HR/payroll), In Extenso Finance (M&A), In Extenso Patrimoine (wealth management), In Extenso Innovation Croissance (innovation tax credits), In Extenso Économie Sociale et Solidaire, and In Extenso Tourisme Culture & Hôtellerie — together with adjacent services such as debt collection (Money Flow), public procurement (Caneva), and hotel transactions (Transaxio Hôtel).

Revenue is generated through a hybrid professional services model: recurring subscription/annual engagements for accounting, payroll, and audit (the compliance backbone), paired with project-based fees for tax advisory, M&A, business creation, legal, and wealth management work. Go-to-market relies on a nationwide network of regional agencies providing face-to-face advisory relationships, supplemented by the Inexweb digital portal and content marketing (Magaz'in blog, podcasts, white papers, webinars, industry events). The broader In Extenso network ranks #1 in France for accounting expertise (La Profession Comptable 2025) and operates 7,300+ collaborators across France, Belgium, Luxembourg, Switzerland, and Spain.
