Omnyacc

What Omnyacc does

Omnyacc (legal entity Omnyacc Federatie, trading as Omnyacc Accountants & Adviseurs) is a Dutch accountancy and advisory firm founded in 1930, headquartered in Den Helder, Netherlands. The firm operates across eight physical offices in North Holland and Northern Netherlands — Assen, Den Helder, Groningen, Heerhugowaard, Hoorn, Leeuwarden, Schagen, and Texel — with roughly 300 specialists. It delivers a one-stop-shop service model built around six disciplines: Accountancy & Administration, Audit & Assurance, Tax Advisory (Fiscaal Advies), Legal Advisory (Juridisch Advies), Personnel & Pension (Personeel en Pensioen), and Strategic Business Advisory (Strategisch Bedrijfsadvies), with add-on services such as OmnyVitaal (absence management/reintegration) and Toekomstgesprek (strategic visualization).

The underlying technology stack consists of recommended and supported third-party platforms — Exact, Twinfield, Unit4 Multivers Online, SnelStart, King Finance, AccountView for accounting; Nmbrs for HRM and payroll; Visionplanner for financial planning and BI; and Basecone for automated invoice scanning with native integration to the firm's recommended accounting suites. Operational tooling includes ISL Online remote support and SmartLockr secure file transfer. The firm does not sell software; rather, professional-services delivery is wrapped around and integrated with these platforms, supplemented by a client portal. The firm holds no disclosed patents, AI/ML research output, or proprietary models.

The revenue model is professional-services based across all five revenue streams. Pricing is not publicly disclosed; fees are customised per client engagement, segmented by ZZP'ers (self-employed), MKB-ondernemers (SMB entrepreneurs), and large enterprises. Go-to-market is sales-led and relationship-driven through regional office presence and walk-in access, supported by a knowledge bank (news, specials, Magazine Sterk!, visual content) and LinkedIn, Facebook, and Instagram channels. As of 2024 the firm is affiliated with PIA Group Nederland, the leading and fastest-growing Dutch SMB accountancy and advisory network, providing consortium-scale continuity while preserving local identity; the legal parent structure is characterised as a strategic operating company relationship rather than a financial acquisition.
