Growing in what really matters
Pleased to meet you. We are aaff, the merger of Alfa Accountants en Adviseurs and ABAB. With 2,000 colleagues, we form a single team spread across 50 offices throughout the Netherlands. 2,000 owners who set the course together. Doing business together. Building together. That is what we do. And you’ll be part of it from day one.
A new face, 180 years of experience
Although we’ve been around for 180 years combined, it’s quite possible you haven’t heard of aaff yet. The new organisation aaff was formed in 2025 from the merger between ABAB and Alfa Accountants en Adviseurs. We already knew a lot from our roots, but together we know even more!
