moreRSM, the world’s 6th largest audit, accounting and consulting network, is expanding its presence in the Rhône-Alpes region with the acquisition of Sadex, a firm based in the heart of the Alps in Albertville.
Already established in Limas, Crolles, Chambéry and Lyon, this fifth office further reinforces RSM’s regional coverage and extends the reach of its expertise—particularly through a dedicated local payroll and HR services hub.
This operation aligns with RSM’s development strategy focused on delivering multidisciplinary support to businesses through strong regional networks.
It also strengthens RSM’s positioning as a leading network for the strategic support of mid-sized companies (ETIs) and SMEs across local territories.
RSM acquires Sadex, based in Albertville. Founded in 1983 in the heart of the Alps, the firm supports over 350 business leaders and generates annual revenues of €1.7 million.
Sadex also operates as a statutory auditor for regional SMEs and associations.
RSM, a major player in the accounting profession in Rhône-Alpes
RSM continues to expand its presence in France’s second-largest economic region. Already well established with its regional hub in Lyon and offices in Limas, Chambéry, Crolles, and now Albertville, RSM Rhône-Alpes now counts 19 partners and nearly 300 staff. Gautier Caddet, Chartered Accountant and Partner at Sadex—and a former RSM employee—becomes a Partner at RSM and will continue to lead the Albertville office alongside its 17-member team.
To strengthen its role as a strategic partner for business leaders, RSM will rely on Albertville’s multidisciplinary expertise in accounting, statutory audit, legal services, advisory, and a specialised payroll and HR administration team. Together with the Chambéry office, RSM now has 40 staff in Savoie and plans to further grow its teams and expertise in executive wealth management and CSR consulting.
A full range of services for businesses and their leaders
The Albertville office offers a comprehensive range of services, from business creation and HR consulting to strategic growth support in both domestic and international markets. In addition to accounting and tax compliance services, the office operates a specialised hub for payroll processing and HR administration. The team supports a broad client base across sectors that reflect the local economy: construction, industry and trades, retail, hospitality, medical/paramedical/legal professions, and sports.
This integration with RSM’s Rhône-Alpes teams will create multiple synergies, reinforcing existing service lines and enabling the development of new specialisations. RSM also aims to harmonise tools and methods in a spirit of continuity, drawing on the expertise of the founding partners. A strong emphasis will be placed on employee training to ensure excellence across the Rhône-Alpes region.
“Our decision to join RSM was driven by a desire to continue growing our business, and above all, by the strong shared values that unite us. As a former RSM employee with more than ten years of connection to the firm, I know just how central integrity and excellence are in client relationships. This integration allows us to benefit from RSM’s brand recognition and technical expertise to better meet the needs of our clients—whether it’s retirement planning, CSR, or electronic invoicing. Sadex becomes RSM Albertville, while maintaining its core strengths: client proximity, specialised expertise, and team dedication,” says Gautier Caddet, Head of Sadex and new RSM Partner.
“Welcoming Sadex allows us to combine the pleasure of working again with Gautier with the continuation of our regional growth strategy, bringing us closer to key players in the local economy. We share a common vision of client support and clear synergies between our areas of expertise. RSM now has over 40 professionals and partners in Savoie and reaffirms its leadership as a strategic advisor to dynamic ETIs and SMEs in this cross-border region,” adds Bertrand Dufour, Partner and Head of RSM Rhône-Alpes.
