- Hours: Monday through Friday, 8:30 to 12:00 and 14:00 to 17:30
Specialized partners
The office’s particular strength lies in the specialization of its partners, enabling it to handle on-site files that go beyond routine accounting:
- Thierry Sallée, office manager, partner and chartered accountant, real estate specialist;
- Florence Kaszuba, partner, payroll management specialist;
- Mathieu Dreno, partner, chartered accountant and statutory auditor, innovation, mergers and acquisitions and due diligence specialist, franchises representative;
- Damien Radier, partner and chartered accountant, real estate and consolidation specialist.
The published specialisms of its partners thus cover three areas, franchises and networks, real estate and innovation. For a franchisee opening a location, an investor structuring real estate assets or a young innovative business seeking financing, this is a concrete advantage.
Support from creation through transmission
The office offers dedicated services for business creation and takeover, with a free first meeting. It subsequently covers all business needs:
- accounting and annual accounts;
- payroll and human resources;
- tax and legal matters;
- audit and statutory auditor services;
- innovation consulting and asset management;
- business sale and transmission.
Clients also have access to Inexweb, In Extenso’s online management platform, to track accounts, invoice clients, transmit payroll items and communicate with their contact. For payroll, the choice of a payroll provider for an SME follows specific criteria.
The strength of a national network
Behind the Montpellier office stands an accounting group owned by its partners and chartered accountants. In Extenso brings together 7,300 employees, 332 partners and more than 280 offices, for 170,000 clients. For a Montpellier business, this means the possibility of mobilizing group specialists for an international project, external growth transaction or transmission. In nearby Gard, In Extenso also has an office in Nîmes.
How to choose your chartered accountant in Montpellier
Start with your sector
Seasonal tourism, restaurants, health, franchises, rental real estate or innovative startups, each activity has its own rules. Ask the firm which clients in your sector it already follows and who in the team is the specialist.
Look at upcoming stages
A firm is also chosen for what awaits you in two or three years. First hiring, opening a second location, entry of a partner, real estate investment, fundraising or transmission. The more skills a firm brings together in-house, the fewer external service providers you will need to engage.
Clarify the engagement letter
The engagement letter details what is included in fees (annual accounts, tax declarations, payroll, legal secretariat) and what falls under supplementary services. This is the document that avoids misunderstandings. These points are part of the criteria for choosing your chartered accountant.
Check the day-to-day relationship
Who will be your contact, how often will you meet, through what tool will you share documents? These answers weigh as much as pricing in the quality of follow-up.
Ranking methodology
The four firms were assessed on 24 October 2026 against the same ten criteria, based on the public pages of their websites (local branch pages, offers, online tools), the directory of the French Order of Chartered Accountants and review platforms. Only chartered accountancy firms that support businesses in the Montpellier area are ranked. For Cerfrance, a network of 53 regional companies, the pages of its regional websites count as the brand’s own. The first three criteria, assessed at brand level, are the same in every ranking on this site that includes In Extenso; the next seven cover local presence and day-to-day service.
Scoring grid. Each criterion that is met earns 1 point and is marked Yes. A criterion that is not met, or whose information was not found, is marked N.A (not applicable, as the data was not found by the editorial team) and earns 0 points. All criteria have the same weight, 1/10 of the overall score each (about 10%). The position follows from the overall score.
