What Newtone does

Newtone B.V. is a Dutch advisory and accounting firm created in April 2024 through the merger of three regional predecessors — HLB Witlox Van den Boomen (Central region), PKF Wallast (Western region), and Koenen en Co (Southern region) — and operates as part of the international HLB network. The firm employs more than 1,100 professionals across twelve offices in Limburg, Noord-Brabant, and the Randstad, serving entrepreneurial and professional Netherlands with a horizontal client mix that includes entrepreneurs, professionals, high-net-worth individuals, investors, and non-profit organisations.

The firm delivers eleven integrated service lines: accountancy and business advisory, audit and assurance, tax advisory, corporate finance, data/innovation/digitalisation, ESG and sustainability (including CSRD compliance and an SDG Quickscan tool), estate planning, international business, legal advisory, payroll and HRM consulting, and subsidy advisory. Underlying technology is built on third-party integrations — Exact Online, Twinfield, Nmbrs, Loket, SmartLockr, Visma Connect, and the Engyon audit platform — accessed through the Mijn Newtone client portal, which still operates across three regional legacy login environments pending unification.

Revenue is generated through professional services engagement: quote-based, multi-year contracts delivered by dedicated account managers and multidisciplinary teams via direct, relationship-led sales. The firm offers free initial consultations, runs active thought-leadership content marketing, and extends its Benelux reach through a 2024 strategic partnership with PKF BOFIDI. Client logos span fashion retail, logistics, construction, landscaping, healthcare, manufacturing, and charity, indicating a deliberately diversified mid-market book rather than vertical concentration.
