The acquisition marks a significant milestone in S&W’s international expansion strategy - backed by Apax Funds, which acquired the firm in March 2025 – and to further strengthen its ability to support clients across Europe. Following S&W’s two acquisitions in Ireland last year, the addition of Vachon enhances the firm’s growing cross border capabilities and deepens the support it provides to internationally active businesses.

Established in 1997, Vachon delivers audit, accounting, tax, payroll and advisory services to SMEs, mid-sized businesses and large international groups, as well as, family offices, private investors, investment funds and their portfolio companies. The firm’s 50 strong bilingual team - which includes 14 Partners - is recognised for its deep audit and accounting expertise notably in international accounting standards and cross-border tax and payroll frameworks.
