What DSM Consulting does

DSM Consulting is a Belgian accounting and tax advisory firm headquartered in Lier, founded in 1996 by Yannick De Smedt. The firm operates as a recognized accounting and tax office affiliated with the Instituut van Accountants en Belastingconsulenten (IAB), delivering an integrated suite of services including bookkeeping, VAT filings, year-end closing, tax advisory, legal advice (corporate law, restructuring, contracts), corporate finance, mergers and acquisitions, and wealth and succession planning. Its core delivery relies on digital accounting solutions that provide real-time access to financial figures for clients, framed as "smart digital solutions" with an emphasis on ease of use.

The firm targets Belgian entrepreneurs and SMEs across five named segments: starters, SMEs/KMOs, management companies, medical professionals, and holding structures. Service delivery is relationship-driven and face-to-face from the single Lier office (Antwerpsestraat 148), with no public pricing disclosed; engagements are structured on retainer and project bases typical of mid-sized professional services firms in the region. The team comprises 11 employees including 3 partners (vennoten).

In February 2026, DSM Consulting was acquired by PIA Group, the fastest-growing accountancy, audit, and advisory network in the Benelux region (52 brands, 92 offices, €440m / ~$515m consolidated turnover in 2025). DSM now operates as a member office within this network, gaining access to group-level resources, cross-referrals, and shared digital infrastructure while retaining its local identity and client relationships in the Lier/Flanders region.

Scale indicators3 records

Direct peers

• VGD: Belgian mid-sized accountancy and advisory firm serving SMEs and entrepreneurs with integrated accounting, tax, and corporate finance services — directly comparable to DSM's full-service local-firm model in the Flemish market.
• Moore Belgium: Member of the Moore Global network in Belgium, providing accounting, tax, and advisory services to mid-market and SME clients. Comparable to DSM as a multidisciplinary mid-tier Belgian practice with similar client segments.
• Baker Tilly Belgium: Belgian member of the Baker Tilly international network, offering accountancy, tax, and advisory services to Belgian SMEs and family-owned businesses. Closely comparable service portfolio and target market to DSM Consulting.
• BDO Belgium: Belgian member of the BDO international accounting network, offering accounting, tax, and advisory services. Similar full-service SME focus, though typically larger office footprint than DSM's single Lier location.
• Accofisc: Belgian accounting and tax advisory firm acquired by PIA Group concurrently with DSM Consulting in February 2026. Direct peer within the same PIA Group network with comparable size, service mix, and SME client focus.
• Grant Thornton Belgium: Belgian mid-tier advisory firm serving SMEs, entrepreneurs, and mid-market companies with audit, tax, and consulting services. Directly comparable in size tier and client focus to DSM.
• Warfid: Belgian accountancy firm also acquired by PIA Group as part of the same five-firm February 2026 transaction. Comparable in scale and service profile to DSM Consulting.

Broad incumbents

• Deloitte Belgium: Big 4 firm with a Belgian practice serving large enterprises, mid-market, and SME clients across audit, tax, consulting, and advisory. Competes with DSM for Belgian SME advisory mandates but operates at substantially larger scale and broader service breadth.
• KPMG Belgium: Big 4 firm providing audit, tax, and advisory services in Belgium. Overlaps with DSM's SME advisory positioning but operates as a broad incumbent with global resources rather than a local specialist.

Emerging players

• Accountable: Belgian digital-first accounting and tax platform targeting self-employed professionals and small businesses with automated bookkeeping and VAT filings. An emerging competitive threat to DSM's traditional SME compliance book, particularly among the 'Starters' segment.
