aaff B.V. is a Dutch accountancy and business advisory organisation formed in 2025 through the merger of Alfa Accountants & Adviseurs and ABAB. The firm combines roughly 180 years of accumulated experience with a presence at over 50 locations across the Netherlands, employing approximately 2,000 colleagues who work with entrepreneurs and small and medium-sized businesses as a comprehensive business partner.

The organisation covers a broad technical range, including accountancy, audit and assurance, corporate finance, and tax and legal advisory. Tax work extends to international tax structuring, transfer pricing and cross-border VAT compliance. Other service lines include salary administration, payroll and staffing solutions, consultancy tailored to specific industry sectors, and global mobility services supporting international entrepreneurs and Dutch businesses expanding abroad.

Staff arrangements are distinctive. All approximately 2,000 employees are co-owners of the company through an employee co-ownership model in which colleagues can invest in the business, and profit-sharing arrangements are in place.
