INAA Group

What INAA Group does

INAA Group (International Association of Independent Accounting Firms) is a Brussels-headquartered, Belgian-registered not-for-profit association (aisbl) founded in 1992. It operates as a membership-based international alliance of 140 independent accounting firms spanning approximately 50 countries, with combined member income of €525 million. Its core function is to enable cross-border professional collaboration among member firms through referral networks, joint project execution, training programs, and shared service partnerships, serving member firms whose end clients range from local SMEs to internationally active corporates.

The association generates revenue through membership subscription fees paid by its 140 member firms; this is the sole disclosed revenue mechanism and is consistent with its not-for-profit, cost-recovery structure. Its value proposition to members is operational rather than technological: access to a curated international referral network (90% of members report recurring referrals, 44% work on joint projects, with an average of 68 new clients introduced per member per year), supplemented by member services spanning legal collaboration (Consulegis), cybersecurity (Lupasafe, Sequrest), continuing professional education (NASBA accreditation), and M&A advisory access (ALTAC International, DealFox). Recent partnerships with ALTAC International and DealFox, both dated 2025-06-16, extend the alliance into M&A deal sourcing and corporate finance advisory. Earlier reputational milestones include a #14 ranking in the 2018 Accountancy Age Top 20 International Alliances.

INAA's operating model is governance-driven rather than product-led: a central secretariat coordinates activities among autonomous member firms, and there is no evidence of proprietary technology platform development or capital-raising activity. The association does not develop in-house AI/ML capabilities, and its competitive position rests on network scale, brand longevity (30+ years), and the depth of its partnership ecosystem rather than on technology differentiation.
