Fiduciaire du Grand-Duché de Luxembourg - FLUX is a Luxembourg fiduciary and accounting firm that provides accounting, tax compliance, company valuation and family-office services to small and medium sized enterprises and entrepreneurs. The practice handles statutory accounting, payroll and corporate secretarial duties while supporting clients with financial reporting and valuation work tailored to Luxembourg regulatory requirements.
The firm was led by chartered accountants Florence Bastin and Marc Meyers, who co-managed FLUX and built a client base focused on wealth structuring and business transfers. Leadership subsequently restructured its advisory activities while the fiduciary business was transferred to another local firm at the end of 2022 and early 2023.
FLUX emphasizes personalised, compliance-focused service for owner-managed businesses and family clients, integrating accounting discipline with practical advice on corporate governance, liquidity management and cross-border matters. The firm draws on subject-matter experience in audits, company valuations and director or liquidator mandates to help clients navigate regulatory and transactional challenges.
