What Fidexpert group does

Fidexpert group operates as a fiduciaire (accounting and fiduciary firm) in Swiss Romandie under the commercial name In Extenso Suisse, delivering accounting, taxation, statutory audit, payroll and HR management, business creation advisory, international expansion consulting, and business transfer services to small and medium enterprises, self-employed independents, and individual clients. The firm was established in 1961 and is headquartered in Montreux, Switzerland, with regional agencies distributed across the French-speaking cantons. It is a subsidiary of the In Extenso Group, a pan-European professional services platform headquartered in France that serves more than 170,000 clients with 7,300 collaborators across France, Belgium, Luxembourg, and Switzerland.

The firm's technology layer consists of two group-developed assets: fulll, a proprietary accounting software used for bookkeeping and financial management, and the Fidexpert client portal built on the HubShare platform for secure document exchange, client communications, and self-service workflows. These tools support but do not differentiate the service offering; the core value delivery remains human-led professional services delivered by certified accountants, tax specialists, and auditors with local expertise in Swiss federal and cantonal regulation. Marketing and client acquisition run primarily through the corporate website, LinkedIn, Instagram, and partnership channels including MassChallenge Switzerland, CCIFS, and the Montreux Comedy Festival 2025.

The revenue model is a professional services model built on retainer arrangements, hourly consulting fees, and project-based engagements, with quote-based pricing calibrated to client size, complexity, and scope. Customer segmentation is horizontal (by client type and life stage rather than by industry vertical), and the firm holds a Great Place to Work certification as an employer brand signal. No revenue figures, funding rounds, or ownership percentages are disclosed in the source data, and the firm operates as a privately held entity within the In Extenso Group structure.
